本公开涉及通信技术领域,尤其涉及一种电路控制方法及移动终端。The present disclosure relates to the field of communication technologies, and in particular, to a circuit control method and a mobile terminal.
相关技术中的一些能够接打电话和拍照的移动终端(如手机、平板电脑)中,一般都配置有听筒模组和摄像模组,而在移动终端的正面分别对应听筒模组和摄像模组,开设有一功能孔(即听筒孔和透光孔)。听筒孔是用于将听筒模组产生的声音传导出来,在用户贴近听筒孔的时候,可以进行声音的听取。透光孔是用于摄像模组中的感光芯片,能够通过该透光孔进行感光,以采集外界图像。无论是听筒孔还是透光孔都是不可缺少的功能孔。但在移动终端开设这两个功能孔,会占用一定的屏幕空间,对于相关技术中的移动终端的屏幕无孔化或者少孔化的全面屏发展趋势,这两个功能孔占用了相对比较大面积的屏幕空间,会影响全面屏的发展。Some mobile terminals (such as mobile phones and tablet computers) capable of receiving calls and taking pictures in related technologies are generally equipped with a handset module and a camera module, and the front of the mobile terminal corresponds to the handset module and the camera module, respectively. There is a function hole (ie, a handset hole and a light-transmitting hole). The earpiece hole is used to conduct the sound generated by the earpiece module. When the user is close to the earpiece hole, the sound can be heard. The light-transmitting hole is a light-sensitive chip used in the camera module. The light-transmitting hole can be used for light-sensing to collect external images. Both the earphone hole and the light transmission hole are indispensable functional holes. However, the opening of these two function holes in a mobile terminal will occupy a certain screen space.

下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例,然而应当理解,可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反,提供这些实施例是为了能够更透彻地理解本公开,并且能够将本公开的范围完整的传达给本领域的技术人员。Hereinafter, exemplary embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a thorough understanding of the present disclosure, and to fully convey the scope of the present disclosure to those skilled in the art.
依据本公开实施例的一个方面,提供了一种电路控制方法,应用于一听筒与摄像头的组合装置(以下简称为组合装置)。According to an aspect of the embodiments of the present disclosure, a circuit control method is provided, which is applied to a combination device of an earphone and a camera (hereinafter referred to as a combination device).
其中,如图1、图3和图8所示,该组合装置至少包括:环形的听筒振膜101、环形线圈102、磁铁103(如永磁铁)、镜头模组104和切换开关106。As shown in FIG. 1, FIG. 3, and FIG. 8, the combined device includes at least a ring-shaped handset diaphragm 101, a ring coil 102, a magnet 103 (such as a permanent magnet), a lens module 104, and a switch 106.
其中,听筒振膜101通过振动起到发声作用,其设置于移动终端的显示屏盖板114上,以便用户进行声音的听取,具体为:显示屏盖板114上开设 有一通孔109,听筒振膜101设置于该通孔109中。Wherein, the earpiece diaphragm 101 plays a role of sound through vibration, and is arranged on the display cover 114 of the mobile terminal so that the user can listen to the sound. Specifically, the display cover 114 is provided with a through hole 109 for the handset to vibrate. The film 101 is disposed in the through hole 109.
其中,环形线圈102对应设置于听筒振膜101下方,其上连接有通电端子105,用于音频电路107或摄像头马达驱动电路108电连接(以下简称马达驱动电路108)。Among them, the toroidal coil 102 is correspondingly disposed below the earpiece diaphragm 101, and a power-on terminal 105 is connected to the toroidal coil 102 for electrical connection of the audio circuit 107 or the camera motor driving circuit 108 (hereinafter referred to as the motor driving circuit 108).
其中,镜头模组104用于采集外界图像,位于环形线圈102的中心孔内,与环形线圈102固定连接。本公开实施例中,镜头模组104与听筒振膜101中间的孔相对设置,这样镜头模组104可以通过听筒振膜101中间的孔,采集外界图像。The lens module 104 is used to collect external images. The lens module 104 is located in the central hole of the toroidal coil 102 and is fixedly connected to the toroidal coil 102. In the embodiment of the present disclosure, the lens module 104 and the hole in the middle of the earpiece diaphragm 101 are oppositely disposed, so that the lens module 104 can collect external images through the hole in the middle of the earpiece diaphragm 101.
其中,磁铁103围绕环形线圈102设置,用于提供磁场环境,使线圈通电时可以产生一定方向的磁场力。具体为,线圈通电时,线圈产生的磁场发生变化,进而使磁铁103与线圈之间的磁力发生变化,从而使磁铁103与线圈之间的距离发生变化。The magnet 103 is arranged around the toroidal coil 102 and is used to provide a magnetic field environment, so that when the coil is energized, a magnetic field force in a certain direction can be generated. Specifically, when the coil is energized, the magnetic field generated by the coil changes, and further, the magnetic force between the magnet 103 and the coil changes, so that the distance between the magnet 103 and the coil changes.
其中,切换开关106不仅与环形线圈102上的通电端子105电连接,还与音频电路107或马达驱动电路108电连接,用于使环形线圈102与音频电路107电连接或与马达驱动电路108电连接。其中,音频电路107用于驱动环形线圈102带动听筒振膜101进行振动发声,马达驱动电路108用于驱动环形线圈102带动镜头模组104进行对焦。Among them, the switch 106 is not only electrically connected to the energized terminal 105 on the toroidal coil 102, but also to the audio circuit 107 or the motor driving circuit 108, and is used to electrically connect the toroidal coil 102 to the audio circuit 107 or to the motor driving circuit 108. connection. The audio circuit 107 is used to drive the ring coil 102 to drive the handset diaphragm 101 to vibrate and sound, and the motor drive circuit 108 is used to drive the ring coil 102 to drive the lens module 104 to focus.
本公开实施例提供的组合装置既能够实现听筒功能,又能够实现摄像头功能,如图2所示,该组合装置的电路控制方法包括:The combination device provided by the embodiment of the present disclosure can implement both the handset function and the camera function. As shown in FIG. 2, the circuit control method of the combination device includes:
步骤201:检测该组合装置的工作模式。Step 201: Detect the working mode of the combined device.
其中,该组合装置的工作模式包括:听筒工作模式和摄像头工作模式。The working mode of the combined device includes a handset working mode and a camera working mode.
步骤202:在检测到组合装置工作于听筒工作模式下时,控制切换开关导通通电端子与音频电路,环形线圈接收音频电路的音频信号,根据音频信号带动所述听筒振膜振动进行发声。Step 202: When it is detected that the combined device works in the earpiece working mode, control the switch to turn on the power-on terminal and the audio circuit, and the ring coil receives the audio signal of the audio circuit, and drives the earpiece diaphragm to vibrate for sound according to the audio signal.
其中,在听筒工作模式下时,环形线圈102与听筒振膜101相抵触,环形线圈102接收音频电路107的音频信号,该音频信号驱动环形线圈102小幅度运动,小幅度运动的环形线圈102又带动环形振膜振动,使环形振膜发声,而不同的电流产生不同的振动,从而使环形振膜发出不同的声音。Among them, in the earpiece working mode, the toroidal coil 102 and the earpiece diaphragm 101 are in conflict. The toroidal coil 102 receives the audio signal of the audio circuit 107. The audio signal drives the toroidal coil 102 to move in small amplitude, and the toroidal coil 102 in small amplitude to move again. The ring diaphragm is driven to vibrate, making the ring diaphragm sound, and different currents generate different vibrations, so that the ring diaphragm emits different sounds.
需要说明的是,虽然环形线圈102与听筒振膜101并没有固定连接在一 起,但是由于环形线圈102与听筒振膜101之间的振动只是小幅度振动,是十分微小的,因此,只需满足环形线圈102与听筒振膜101相抵触,即可保证环形线圈102与听筒振膜101的持续接触。It should be noted that although the toroidal coil 102 and the handset diaphragm 101 are not fixedly connected, since the vibration between the toroidal coil 102 and the handset diaphragm 101 is only a small amplitude vibration, it is very small, so it only needs to meet If the toroidal coil 102 and the handset diaphragm 101 are in conflict, continuous contact between the toroidal coil 102 and the handset diaphragm 101 can be ensured.
步骤203:在检测到组合装置工作于摄像头工作模式下时,控制切换开关导通通电端子与马达驱动电路,环形线圈与听筒振膜间隔第一预设距离,环形线圈接收马达驱动电路的对焦驱动信号,根据对焦驱动信号,带动镜头模组向靠近或远离显示屏盖板的方向移动进行对焦。Step 203: When it is detected that the combined device works in the camera working mode, the control switch is turned on to energize the terminal and the motor drive circuit, the ring coil and the earphone diaphragm are spaced a first preset distance, and the ring coil receives the focus drive of the motor drive circuit. Signal, according to the focus drive signal, drives the lens module to move toward or away from the display cover for focusing.
其中,在摄像头工作模式下时,环形线圈102与听筒振膜101是相分离的,环形线圈102接收马达驱动电路108的对焦驱动信号,根据该对焦驱动信号,带动环形线圈102向靠近显示屏盖板114或远离显示屏盖板114的方向(即靠近听筒振膜101或远离听筒振膜101的方向)运动,由于镜头模组104固定于环形线圈102上,因此,在环形线圈102的带动下,镜头模组104同样会向靠近显示屏盖板114或远离显示屏盖板114的方向移动,从而实现对焦。Among them, in the camera working mode, the toroidal coil 102 is separated from the handset diaphragm 101. The toroidal coil 102 receives the focus driving signal of the motor driving circuit 108, and according to the focus driving signal, the toroidal coil 102 is driven closer to the display cover. The plate 114 moves in a direction away from the display cover 114 (that is, in a direction close to the earpiece diaphragm 101 or away from the earpiece diaphragm 101). Since the lens module 104 is fixed on the toroidal coil 102, it is driven by the toroidal coil 102 The lens module 104 will also move toward or away from the display cover 114 to achieve focusing.
具体地,如图3所示,图像传感器将镜头模组104采集的光学图像转换成电子信号,发送至图像处理器,图像处理器接收到图像传感器发送的电子信号后,根据自动对焦(Auto Focus,AF)算法,确定需要对焦的距离,马达驱动电路108根据需要对焦的距离,驱动环形线圈102带动镜头模组104进行对焦。Specifically, as shown in FIG. 3, the image sensor converts the optical image collected by the lens module 104 into an electronic signal and sends it to the image processor. After receiving the electronic signal sent by the image sensor, the image processor (AF) algorithm to determine the distance that needs to be focused, and the motor driving circuit 108 drives the ring coil 102 to drive the lens module 104 to focus according to the distance that needs to be focused.
需要说明的是,为了避免在对焦过程中,环形线圈102与听筒振膜101碰触,设计镜头模组104的初始对焦位置为:环形线圈102与听筒振膜101间隔第一预设距离,且镜头模组104的最近对焦距离(即靠近显示屏盖板114方向的最大对焦距离)不超过该第一预设距离,该第一预设距离可根据镜头模组104的对焦需求进行设计。It should be noted that in order to avoid the ring coil 102 and the handset diaphragm 101 from touching during the focusing process, the initial focus position of the lens module 104 is designed as follows: the ring coil 102 and the handset diaphragm 101 are separated by a first preset distance, and The closest focusing distance of the lens module 104 (ie, the maximum focusing distance near the display cover 114) does not exceed the first preset distance, and the first preset distance can be designed according to the focusing requirements of the lens module 104.
本公开实施例提供的电路控制方法,通过对该组合装置的控制,使该组合装置既实现了听筒功能,又实现了摄像头功能。According to the circuit control method provided in the embodiment of the present disclosure, by controlling the combined device, the combined device realizes both the handset function and the camera function.
进一步地,本公开实施例中,对于该组合装置的初始状态(即不通电状态),可以设计环形线圈102与听筒振膜101相抵触,或环形线圈102与听筒振膜101之间间隔第二预设距离,其中,该第二预设距离大于、等于或小于 第一预设距离,具体情况可根据实际需求设计。Further, in the embodiment of the present disclosure, for the initial state of the combined device (that is, the non-energized state), the toroidal coil 102 and the earpiece diaphragm 101 can be designed to be in conflict, or the interval between the toroidal coil 102 and the earpiece diaphragm 101 is second. The preset distance, where the second preset distance is greater than, equal to, or less than the first preset distance, and the specific situation can be designed according to actual needs.
本公开实施例中,该组合装置的初始状态可选为:环形线圈102与听筒振膜101相抵触,这样,在启动移动终端上的听筒工作时,环形线圈102可以直接根据音频电路107的音频信号,带动听筒振膜101振动,而不必先控制环形线圈102与听筒振膜101相抵触,再进行听筒发声,减小时延。In the embodiment of the present disclosure, the initial state of the combined device may be selected as follows: the ring coil 102 is in conflict with the earpiece diaphragm 101. In this way, when the earpiece on the mobile terminal is started to work, the ring coil 102 may be directly based on the audio of the audio circuit 107. The signal drives the handset diaphragm 101 to vibrate, without having to control the ring coil 102 and the handset diaphragm 101 to interfere first, and then the handset emits sound to reduce the time delay.
其中,当该组合装置的初始状态(即不通电状态)为:环形线圈102与听筒振膜101相抵触时,在该环形线圈接收马达驱动电路的对焦驱动信号,根据对焦驱动信号带动镜头模组向靠近或远离显示屏盖板的方向移动进行对焦之前,该电路控制方法还包括:Wherein, when the initial state of the combined device (that is, the non-energized state) is: when the toroidal coil 102 and the handset diaphragm 101 are in conflict, the toroidal coil receives a focus driving signal from a motor driving circuit, and drives the lens module according to the focus driving signal. Before moving toward or away from the display cover to focus, the circuit control method further includes:
环形线圈接收马达驱动电路的第一初始驱动信号,并根据该第一初始驱动信号,向远离显示屏盖板的方向移动第一预设距离,形成镜头模组的初始对焦位置。The toroidal coil receives a first initial driving signal of the motor driving circuit, and according to the first initial driving signal, moves a first preset distance in a direction away from the display screen cover to form an initial focusing position of the lens module.
也就是,当启动摄像头工作时,马达驱动电路108首先会给一定电流(即第一初始驱动信号)到环形线圈102,拉动环形线圈102脱离听筒振膜101,在环形线圈102与听筒振膜101间隔第一预设距离时,停止拉动环形线圈102,并将当前位置记录为镜头模组104的初始对焦位置。在这之后,马达驱动电路108再发送对焦驱动信号至环形线圈102,控制环形线圈102带动镜头模组104较大幅度移动,实现对焦。That is, when the camera is started, the motor driving circuit 108 first gives a certain current (ie, the first initial driving signal) to the toroidal coil 102, pulls the toroidal coil 102 away from the handset diaphragm 101, and the ring coil 102 and the handset diaphragm 101 When the first preset distance is separated, the ring coil 102 is stopped from being pulled, and the current position is recorded as the initial focus position of the lens module 104. After that, the motor driving circuit 108 sends a focus driving signal to the toroidal coil 102 again, and controls the toroidal coil 102 to drive the lens module 104 to move in a larger range to achieve focusing.
进一步地,当该组合装置的初始状态为:环形线圈102与听筒振膜101之间间隔第二预设距离时,在环形线圈接收马达驱动电路的对焦驱动信号,根据对焦驱动信号带动镜头模组向靠近或远离显示屏盖板的方向移动进行对焦之前,该电路控制方法还包括:Further, when the initial state of the combined device is: when the ring coil 102 and the handset diaphragm 101 are spaced a second preset distance, the focus driving signal of the motor driving circuit is received in the ring coil, and the lens module is driven according to the focus driving signal. Before moving toward or away from the display cover to focus, the circuit control method further includes:
环形线圈接收马达驱动电路的第二初始驱动信号,根据第二初始驱动信号,向远离或靠近显示屏盖板的方向移动第三预设距离,形成镜头模组的初始对焦位置。The toroidal coil receives a second initial driving signal of the motor driving circuit, and moves a third preset distance in a direction away from or close to the display cover according to the second initial driving signal to form an initial focusing position of the lens module.
也就是,当启动摄像头工作时,马达驱动电路108首先会给一定电流(即第二初始驱动信号)到环形线圈102,使环形线圈102带动镜头模组104向远离或靠近显示屏盖板114的方向移动,在环形线圈102与听筒振膜101间隔第一预设距离时,停止环形线圈102的移动,并将当前位置记录为镜头模 组104的初始对焦位置。在这之后,马达驱动电路108再发送对焦驱动信号至环形线圈102,控制环形线圈102带动镜头模组104较大幅度移动,实现对焦。That is, when the camera is started, the motor driving circuit 108 first gives a certain current (ie, the second initial driving signal) to the toroidal coil 102, so that the toroidal coil 102 drives the lens module 104 away from or near the display cover 114. When the ring coil 102 is separated from the earphone diaphragm 101 by the first preset distance, the movement of the ring coil 102 is stopped, and the current position is recorded as the initial focus position of the lens module 104. After that, the motor driving circuit 108 sends a focus driving signal to the toroidal coil 102 again, and controls the toroidal coil 102 to drive the lens module 104 to move in a larger range to achieve focusing.
其中,若第二预设距离大于第一预设距离,则控制环形线圈102带动镜头模组104向靠近显示屏盖板114的方向移动;若第二预设距离小于第一预设距离,则控制环形线圈102带动镜头模组104向远离显示屏盖板114的方向移动;若第二预设距离等于第一预设距离,则环形线圈102保持不动。If the second preset distance is greater than the first preset distance, the loop coil 102 is controlled to drive the lens module 104 to move closer to the display cover 114; if the second preset distance is less than the first preset distance, then Controlling the loop coil 102 drives the lens module 104 to move away from the display screen cover 114; if the second preset distance is equal to the first preset distance, the loop coil 102 remains motionless.
其中,为了保证用户的使用体验,本公开实施例中,在镜头模组104处于初始对焦位置时,再控制移动终端的显示屏显示镜头模组104采集的图像,以避免环形线圈102带动镜头模组104处于初始对焦位置过程中,摄像头采集的图像显示在显示屏上,出现显示画面不稳定的情况发生。In order to ensure the user experience, in the embodiment of the present disclosure, when the lens module 104 is in the initial focus position, the display of the mobile terminal is controlled to display the images collected by the lens module 104 to prevent the ring coil 102 from driving the lens module. While the group 104 is in the initial focus position, the image collected by the camera is displayed on the display screen, and the display image is unstable.
其中,当该组合装置的初始状态为:环形线圈102与听筒振膜101之间间隔第二预设距离时,在环形线圈接收音频电路的音频信号,根据音频信号带动听筒振膜振动进行发声之前,该电路控制方法还包括:Wherein, when the initial state of the combined device is: when the ring coil 102 and the earpiece diaphragm 101 are separated by a second predetermined distance, before the ring coil receives the audio signal of the audio circuit, the earpiece diaphragm is driven to vibrate according to the audio signal to make a sound. The circuit control method further includes:
环形线圈接收音频电路的第三初始驱动信号,根据第三初始驱动信号,向靠近听筒振膜101的方向移动,与听筒振膜101相抵触。The toroidal coil receives the third initial driving signal of the audio circuit, and according to the third initial driving signal, moves to a direction close to the earpiece diaphragm 101, and conflicts with the earpiece diaphragm 101.
也就是,当启动听筒工作时,音频电路107首先会给一定电流(即第三初始驱动信号)到环形线圈102,使环形线圈102靠近显示屏盖板114的方向移动,使环形线圈102与听筒振膜101相抵触。在这之后,音频电路107再发送音频信号至环形线圈102,控制环形线圈102带动听筒振膜101振动,实现发声。That is, when the earpiece is activated, the audio circuit 107 first gives a certain current (ie, the third initial driving signal) to the toroidal coil 102, so that the toroidal coil 102 moves closer to the display cover 114, so that the toroidal coil 102 and the earpiece are moved. The diaphragm 101 is in conflict. After that, the audio circuit 107 sends an audio signal to the toroidal coil 102, and controls the toroidal coil 102 to drive the handset diaphragm 101 to vibrate to achieve sound.
进一步地,如图1所示,该镜头模组104包括:与环形线圈102固定连接的载体1041和设置于载体1041上的镜头1042,也就是,镜头1042通过载体1041与环形线圈102固定连接,从而使环形线圈102带动镜头1042进行向靠近或远离显示屏盖板114的方向移动。Further, as shown in FIG. 1, the lens module 104 includes a carrier 1041 fixedly connected to the ring coil 102 and a lens 1042 disposed on the carrier 1041, that is, the lens 1042 is fixedly connected to the ring coil 102 through the carrier 1041. As a result, the ring coil 102 drives the lens 1042 to move toward or away from the display screen cover 114.
进一步地,如图4所示,该组合装置还包括:第一弹片111和/或第二弹片112。其中,第一弹片111设置于镜头模组104朝向听筒振膜101的一侧,第二弹片112设置于镜头模组104背离听筒振膜101的一侧。其中,第一弹片111和第二弹片112的具体结构形状,可根据实际需求选择,本公开实施 例对此不进行限定。Further, as shown in FIG. 4, the combined device further includes: a first elastic piece 111 and / or a second elastic piece 112. The first elastic piece 111 is disposed on a side of the lens module 104 facing the earpiece diaphragm 101, and the second elastic piece 112 is disposed on a side of the lens module 104 facing away from the earpiece diaphragm 101. The specific structural shapes of the first elastic piece 111 and the second elastic piece 112 can be selected according to actual needs, which is not limited in the embodiments of the present disclosure.
其中,第一弹片111和第二弹片112能够起到平衡电磁力的作用,以调节镜头模组104的移动位置,达到对镜头1042的微距离调整,调整对焦平面,实现清晰影像的目的。例如,设置两个弹片时,当镜头模组104向靠近显示屏盖板114的方向移动过程中,第一弹片111可以对镜头模组104产生与镜头模组104移动方向相反的作用力,而第二弹片112也可以对镜头模组104产生与镜头模组104移动方向相反的作用力,通过第一弹片111和第二弹片112的作用力之和平衡电磁力,避免镜头模组104过度向靠近显示屏盖板114的方向移动,导致环形线圈102与听筒振膜101抵触。同样的,当镜头模组104向远离显示屏盖板114的方向移动过程中,第一弹片111可以对镜头模组104产生与镜头模组104移动方向相反的作用力,而第二弹片112也可以对镜头模组104产生与镜头模组104移动方向相反的作用力,以平衡电磁力,避免镜头模组104过度向远离显示屏盖板114的方向移动。当然可以理解的是,第一弹片111对镜头模组104的作用力方向与第二弹片112对镜头模组104的作用力方向不一定要相同,具体情况,可根据两个弹片的拉伸或压缩的状态确定。而具体在组合装置中设置哪个弹片,也可根据实际需求选择。Among them, the first elastic sheet 111 and the second elastic sheet 112 can balance the electromagnetic force to adjust the moving position of the lens module 104, to achieve the fine-distance adjustment of the lens 1042, adjust the focus plane, and achieve a clear image. For example, when two shrapnels are provided, when the lens module 104 moves in a direction close to the display cover 114, the first shrapnel 111 can generate a force on the lens module 104 opposite to the moving direction of the lens module 104, and The second shrapnel 112 can also generate a force on the lens module 104 that is opposite to the movement direction of the lens module 104. The electromagnetic force is balanced by the sum of the forces of the first shrapnel 111 and the second shrapnel 112 to prevent the lens module 104 from being excessively moved. Moving in a direction closer to the display cover 114 causes the toroidal coil 102 to interfere with the handset diaphragm 101. Similarly, when the lens module 104 is moved away from the display cover 114, the first elastic piece 111 can generate a force on the lens module 104 opposite to the moving direction of the lens module 104, and the second elastic piece 112 also A force acting on the lens module 104 opposite to the moving direction of the lens module 104 may be generated to balance the electromagnetic force and prevent the lens module 104 from moving excessively away from the display cover 114. Of course, it can be understood that the direction of the acting force of the first elastic piece 111 on the lens module 104 and the direction of the acting force of the second elastic piece 112 on the lens module 104 are not necessarily the same. The state of the compression is determined. Specifically, which shrapnel is set in the combination device can also be selected according to actual needs.
其中,本公开实施例中,还可以借助第一弹片111和/或第二弹片112,更好地控制环形线圈102与听筒振膜101相抵触,例如,在组合装置的初始状态下时,在第一弹片111和/或第二弹片112的作用下,可以更好的使环形线圈102与听筒振膜101保持相抵触的状态,或是在听筒工作模式下时,在第一弹片111和/或第二弹片112的作用下,可以更好地控制环形线圈102与听筒振膜101持续抵触。In the embodiment of the present disclosure, the first elastic piece 111 and / or the second elastic piece 112 can also be used to better control the toroidal coil 102 and the earpiece diaphragm 101 to conflict with each other. For example, in the initial state of the combined device, Under the action of the first shrapnel 111 and / or the second shrapnel 112, the ring coil 102 and the earpiece diaphragm 101 can be kept in a better state, or in the working mode of the earphone, the first shrapnel 111 and / or Or, under the action of the second elastic piece 112, it is possible to better control the continuous interference between the toroidal coil 102 and the handset diaphragm 101.
