It should be noted that similar reference numerals and letters indicate similar items in the following figures, therefore, one Once an item is defined in a drawing, it is not required to be further discussed in subsequent figures.

According to an embodiment of the present invention, a speaker device is provided. The device includes a housing, a base 15 and an elastic connection. Any one of the base 15 and the housing has a through hole 18, and a first curved surface 16 is provided around the outer periphery of the through hole 18, and the other of the two has an abutting portion that cooperates with the first curved surface 16. For example, the shape of the through hole 18 is circular, elliptical or polygonal to meet different usage requirements. For example, the first curved surface 16 is a concave curved surface or a convex curved surface. The first curved surface 16 may be a circular arc surface, an elliptical arc surface or an arc surface of any arc set as needed, as long as the relative angle between the base 15 and the casing can be changed.

The resilient connection passes through the through hole 18 and connects the base 15 to the housing. For example, the resilient connection is an elastic rubber piece or an assembly of a plurality of differently functional parts.

The aperture of the through hole 18 is larger than the outer diameter of the elastic connecting portion. Thus, there is sufficient freedom between the base 15 and the housing to change the relative angle, and the resilient connection does not form interference with the base 15 or the housing. The elastic connecting portion is configured to form an elastic force directed from the base 15 toward the housing such that the abutting portion abuts against the first curved surface 16 and the abutting portion is slidable along the first curved surface 16. For example, the abutting portion is a second curved surface 26, a plurality of arcuate surfaces or annular structures disposed at intervals, as long as it can abut against the first curved surface 16 and slide along the first curved surface 16 to connect the base 15 to the housing. The relative angle of the change can be.

For example, the base 15 has a through hole 18, and a first curved surface 16 is provided around the outer periphery of the through hole 18, and an abutting portion is provided on the housing. The abutting portion abuts against the first curved surface 16 and can slide along the first curved surface 16.

For example, the housing has a through hole 18, and a first curved surface 16 is provided around the outer periphery of the through hole 18, and an abutting portion is provided on the base 15. The abutting portion abuts against the first curved surface 16 and can slide along the first curved surface 16.

In the speaker device of the present invention, the first curved surface 16 abuts against the abutting portion and is relatively slidable, so that the set angle between the base 15 and the casing can be changed. Therefore, the orientation of the speaker can be adjusted according to different installation positions, so that the sound effect of the device is good. The adaptability of the speaker device is improved.

Further, the elastic connecting portion can form an elastic force directed from the base 15 toward the housing such that the abutting portion abuts against the first curved surface 16. Thus, the angle between the base 15 and the housing is due to the abutting portion and the first curved surface. The abutment position of 16 changes and changes.

In addition, the spring force creates a frictional force between the base 15 and the housing, which enables the angle between the two to be fixed.

1 is an exploded view of a speaker device in accordance with one embodiment of the present invention. 2 is a cross-sectional view of a speaker device in accordance with one embodiment of the present invention. 3 is a cross-sectional view of a speaker device that rotates a set angle, in accordance with one embodiment of the present invention.

As shown in FIG. 1, the housing includes a front cover 11 and a bottom case 13 that are fastened together. The front cover 11 has an acoustic hole. The bottom case 13 is for connection with the base 15. The interior of the housing forms a cavity. The speaker unit 12 is disposed within the cavity and opposite the sound hole. A circular through hole 18 is provided in the base 15, and a first curved surface 16 surrounding the through hole 18. The first curved surface 16 is a convex curved surface. As shown in FIG. 2, an abutting portion is provided on the bottom case 13, and the abutting portion is a second curved surface 26 that matches the first curved surface 16. The second curved surface 26 is a concave curved surface. Alternatively, the first curved surface has a concave curved surface at 16 positions, and the second curved surface is a convex curved surface. In this way, the relative sliding between the first curved surface 16 and the second curved surface 26 is smoother and the rotational operation is less laborious.

In addition, there is a larger contact area between the first curved surface 16 and the second curved surface 26, and the pressure of the two curved surfaces is small, is not easily damaged, and has a long service life.

Optionally, a damping coating is applied to at least one of the first curved surface 16 and the second curved surface 26. The damping paint can increase the friction between the two arcuate faces, which can fix the angle at which the base 15 and the bottom casing 13 rotate.

In one example, a guide rail extending in a set direction is provided on any one of the first curved surface 16 or the abutment portion, and a groove matching the guide rail is provided on the other, and the guide rail 17 is inserted into the groove Medium to define the direction in which the housing and the base rotate. For example, the setting direction is the direction in which the bottom case 13 and the base 15 are relatively rotated. As shown in FIGS. 1-3, the first curved surface 16 is located on the base 15, and the guide rails are disposed on both sides of the through hole 18 in the rotational direction. Those skilled in the art can set the height of the guide rail according to actual needs. A groove is provided on the second curved surface 26. When assembled, the guide rail 17 is inserted into the groove. The recess forms a definition of the guide rail 17. When rotating, the bottom case 13 and the base 15 can only rotate in the extending direction of the guide rail 17. In this way, the adjustment of the angle between the bottom case 13 and the base 15 is more accurate, and the displacement of the two is avoided at will.

Of course, it is also possible that the guide rail 17 is disposed on the abutting portion (for example, the second curved surface 26). The groove is provided on the first curved surface 16 as long as the direction of rotation can be limited.

In one example, the resilient joint is an assembly of multiple parts. For example, the resilient connection includes a resilient member and a pin 22. The spring element is used to provide spring force and the pin 22 is used to connect the housing to the base 15. One end of the pin 22 is coupled to the housing and the other end is coupled to the base 15. The pin 22 passes through the through hole 18. The diameter of the through hole 18 is larger than the outer diameter of the pin shaft 22. The resilient element is located between the end of the pin 22 and the housing or between the end of the pin 22 and the base 15. The length of the pin 22 is such that there is an axial degree of freedom between the housing and the base 15 to facilitate angular adjustment and assembly of the speaker. For example, as shown in FIG. 7, the pin shaft 22 has a catching portion 23 at both ends. As shown in FIGS. 1-3, the engaging portions 23 of the pin 22 are engaged with the base 15 and the bottom case 13, respectively. This structure facilitates the assembly of the speaker device.

As shown in FIGS. 2-3, during rotation, since the diameter of the through hole 18 is larger than the outer diameter of the pin 22, the bottom case 13 is allowed to move in the radial direction of the pin 22. Since the abutting portion abuts against the first curved surface 16, the position of the bottom case 13 with respect to the first curved surface 16 changes. The change in position changes the angle of the bottom case 13 relative to the base 15, achieving angular adjustment.

Preferably, at least one of the housing and the base 15 is detachably coupled to the pin 22. This arrangement facilitates the connection of the housing to the base 15 and makes assembly of the speaker device simpler. For example, the catching portion 23 is screwed to the pin main body 27. At the time of installation, the engaging portion 23 and the pin main body 27 are first loosened; then, the pin main body 27 passes through the bottom case 13 and the base 15; and the engaging portion 23 is screwed to the pin main body 27.

In one example, the elastic element is a spring 19 . The elastic piece 19 includes a ring member 21 and a plurality of elastic arms 20 connected to the ring member 21. The elastic arm 20 is used to form an elastic force. Each of the elastic arms 20 is coupled to the ring member 21 and extends outwardly, and the spring arm 20 forms a stop with the housing or base 15. The pin 22 passes through the inner ring of the ring member 21. For example, a plurality of elastic arms 20 are evenly arranged around the ring member 21. At the time of assembly, the elastic piece 19 is pressed by the engaging portion 23 of the pin shaft 22, and elastic deformation between the elastic arm 20 and the ring member 21 forms a force for bringing the bottom case 13 close to the base 15. The elastic piece 19 has a simple structure, is convenient to assemble, and has good elasticity.

Preferably, as shown in FIG. 8, the elastic arms 20 are two and are oppositely disposed on both sides of the ring member 21. This saves material and the shrapnel 19 has sufficient spring force. Optionally, the two elastic arms 20 are opposite to the two guide rails 17, respectively. In this way, the elastic piece 19 has in the direction of rotation Sufficient elasticity. Preferably, the elastic piece 19 has a curved surface structure, and the curved surface structure is the same as the convex direction of the first curved surface 16. Thus, the pin 22 can be made shorter and the directivity of the spring force is better.

For example, as shown in FIG. 7, a stepped projection 24 is provided on the pin main body 27. The outer diameter of the stepped projection 24 is the same as the outer diameter of one of the engaging portions 23. For example, the outer diameter of the pin main body 27 is the same as the inner diameter of the ring member 21. In this way, the catching portion 23 can pass through the ring member 21 to facilitate the assembly of the elastic piece 19, and the ring member 21 can be sleeved on the stepped projection 24. Since the outer diameter of the stepped protrusion 24 is the same as the inner diameter of the ring member 21, when the housing and the base 15 are relatively rotated, the stepped protrusion 24 can prevent displacement between the elastic piece 19 and the pin shaft 22, so that the base 15 and the base 15 The elasticity between the housings is stable.

4 is an exploded view of a speaker device in accordance with another embodiment of the present invention. FIG. 5 is a schematic structural view of a speaker device according to another embodiment of the present invention. 6 is a schematic structural view of a speaker device for rotating a set angle according to another embodiment of the present invention.

As shown in FIGS. 4-6, a wave-shaped projection 25 arranged in the rotational direction is provided on either of the base 15 and the housing, and the other of the two is provided with the wavy projection 25. The meshed bumps 14, the undulations 25 and the bumps 14 form a damping gear effect. For example, the damper gear effect means that the undulating projections 25 are engaged with the ribs 14. When rotated, the lobes 14 slide along the peaks and valleys of the undulations 25 to form a frustrating sensation similar to that in the shifting position. And when rotated to a suitable angle, the bumps 14 snap into the valleys of the undulations 25, forming a fix to the angle. By this means of engagement, the adjustment of the angle between the housing and the base 15 can be made more precise and the relative position between the two can be more fixed. In addition, the damping gear effect improves the user experience.

Preferably, the bumps 14 are plural and arranged in the direction of rotation. The arrangement of the plurality of bumps 14 enables the relative position between the base 15 and the housing to be more fixed, effectively avoiding the offset of the relative angle between the housing and the base 15.

While the invention has been described in detail with reference to the specific embodiments of the present invention, it should be understood that It will be appreciated by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the invention. The scope of the invention is defined by the appended claims.
