DE3839084A1 - Communications ear insert - Google Patents

Abstract

Communications devices such as telephones and radios have the disadvantage that they cannot readily be used in a noisy environment, a free hand is required to operate them and they are uncomfortable over longer periods. The object of the present invention is to enable communication to be carried out with free hands and also in a noisy environment. At the same time, the device can be carried inconspicuously. In the solution according to the invention 1. known microphones which are inserted in the ear are used. External noise is thus screened in the ear and the microphone can also be used in a noisy environment; 2. the use of a base station close to the transmitter (e.g. on the body) and a wireless connection are provided.

Description

Communication devices such as telephones or radio devices have that Disadvantage that it is used poorly in a noisy environment can be that you have a free hand to serve them needed and that they are uncomfortable to wear in the long run.

The aim of the present invention is communication both with free hands and in a noisy environment to be able to drive. At the same time, the device can be inconspicuous be worn.

The solution according to the invention is that

• 1. In-ear microphones ( 5 ) are used in the ear communication insert ( Figure 1) that are known from literature and practice. This shields the external noise in the ear and enables the microphone to be used even in a noisy environment. This ear insert consists of a microphone ( 5 ), a transmitter ( 4 ) with the same or separate antenna ( 8 ) and an earphone ( 1 ), a receiver ( 2 ) with the same or separate antenna ( 6 ) and a power supply ( 3 ) and . U. with the same or separate antenna ( 7 );
• 2. the use of a relay station ( Figure 2) not far from the ear insert transmitter antenna ( 8 ) (eg on the body) and a wireless connection are provided. This consists of a relay to the ear transmitter ( 9 ) with a separate ( 14 ) or common antenna and a receiver ( 10 ) with a separate ( 15 ) or common antenna as well as a relay transmitter to the outside ( 12 ) with a separate ( 16 ) or common antenna and a receiver ( 11 ) with ge separated ( 13 ) or common antenna;
• 3. for direct voltage supply ( 3 ), the use of batteries in the ear insert (by supplying HF energy from a relay station) can be avoided, for. B. characterized in that the broadcast in the VHF range and rectification device in the resonance circuit received to supply the devices ( 2 ) and ( 4 );
• 4. a single electro-acoustic transducer ( 21 ) is used both as a microphone and as an earphone by switching ( 20 ) functions ( Figure 3);
• 5. such an ear insert with transmitter ( 19 ) with separate ( 23 ) or common antenna and a receiver ( 25 ) with separate or common antenna ( 22 ) switches the transmission direction between relay station and communication use using the same or two different frequencies may be equal to or different from the power supply frequency;
• 6. non-manually operated switches, e.g. B. switching to speech or acoustic command (also programmed) aku tical switches, which are housed in the ear insert and / or the relay station ( 17 ) used;
• 7. with high-frequency switching ( 20 ) between the transmit and receive function, there is the risk of reverberation of the ear as the cause of noise, so that the reverberation of the inner ear as a source of interference must be eliminated by subtracting a voltage from the transducer serving as the reception level of the microphone is, which is proportional to that in the clock before by the acoustic transducer as earphone voltage. This type of dehalling ( 24 ) is known per se.

The problems described concern both the call devices, that disturb the environment, car phones that do not use the Hands and without attached microphones over headphones, earphones or speakers should work, as well as hearing aids what is known from the literature.

Claims (9)

1. Communication device that is on the body and mostly in the ear is used, with or without its own energy source (Energy source radiated in from outside), the transmission and / or receiving units with at least one electronic acoustic transducers such as microphone or earphones and at least one antenna for reception and / or transmission involves using at least one Frequency for reception and / or broadcast and Transfer of energy from or to a predominantly movable, carried, but also fixed relay station, e.g. B. on the body of the wearer. 2. Use of communication as above, using an electro-acoustic transducer as Microphone and as earphones by switching between both functions. 3. Use of communication according to 1 and 2 above, using an antenna (transmit and receive antenna) with three or more different frequencies for sending and receiving.   4. Communication use according to claims 1 to 3 above, using one antenna and two transmit and Reception frequencies (supply energy through equ direction of the recipient). 5. Communication use according to claims 1 to 4, with an antenna and a transmission and reception frequency, using a switch between transmit and Receive function or change of transmission direction. 6. Communication use according to claims 1 to 5, using two antennas for broadcast and em pfang. 7. Communication use according to claims 1 to 6, while neutralizing the reverberation effects in the ear Use of contained or contained circuit circling. 8.
