Abstract
The invention discloses an external behind-the-ear intercommunication device, which mainly comprises an ordinary telephone, an audio input circuit, an audio output circuit, a telephone receiver, a telephone microphone, a transfer switch, an audio input interface, an audio output interface and the like. The external behind-the-ear intercommunication device is characterized in that: the components are connected by a circuit. When the telephone is answered, the contact of the transfer switch is switched, the audio input circuit is communicated with the telephone microphone or the audio input interface, and the audio output circuit is communicated with the telephone receiver or the audio output interface. The audio input interface and the audio output interface can be externally connected with various behind-the-ear audio input/output devices, thereby realizing transition between a handheld microphone intercommunication way and an external behind-the-ear intercommunication way. The external behind-the-ear intercommunication device can flexibly select an intercommunication way in which a telephone answerer is interested according to the needs of the telephone answerer to bring great convenience to a user of the telephone, and simultaneously has the advantages of simple structure, convenience of manufacturing, low cost and the like.
Description
Technical field
The present invention relates to a kind of external supra-aural communicator.
Background technology
Existing desk telephone set mainly contains two kinds of talking modes, and the one, portable microphone type, the 2nd, hands-free.Dual mode all has shortcoming, and mode one time must be held microphone with hand in conversation, and when answering the call, hand just can not be done other thing, and microphone sound can only import an ear into, and the air time is when longer, can feel that ear and hand all ache very much, uses very inconvenient.Mode two sound effects are bad, and sound by hands-free amplification after, the people around can disturbing, also very inconvenient.
Summary of the invention
The objective of the invention is to solve above-mentioned shortcoming, and a kind of external supra-aural communicator is provided, it is on the basis of ordinary telephone set talking mode, increases a kind of supra-aural talking mode, thereby made telephonic people that more more options are provided, for the people who answers the call provides convenience.
For achieving the above object: external supra-aural communicator, comprise ordinary telephone set, audio frequency input circuit, audio output circuit, phone receiver, phone microphone, change over switch, audio input interface, audio output interface, it is characterized in that electrically connecting between audio frequency input circuit, audio output circuit, phone receiver, phone microphone, change over switch, audio input interface, the audio output interface.When answering the call, by the contact of switch transition switch, the audio frequency input circuit is connected with phone microphone or audio input interface respectively, and audio output circuit is connected with phone receiver or audio output interface respectively.
Above-mentioned audio input interface and audio output interface can external various supra-aural audio frequency input/output units.
Beneficial effect of the present invention:
1, external supra-aural communicator of the present invention is on the basis of ordinary telephone set talking mode, increases a kind of supra-aural talking mode, and this structure is easy to use.
2, external supra-aural communicator of the present invention, have easy to make, low cost and other advantages.
Description of drawings
Fig. 1 is an electrical block diagram of the present invention.
