Abstract
A kind of multifunction wireless hearing aids, comprise MCU, microphone, pick-up coil and loudspeaker, described microphone is connected with MCU, and described pick-up coil is connected with MCU, described MCU connects loudspeaker by a power amplification circuit, and described MCU has a Sound control channel switching module.Cross the setting of microphone and pick-up coil, the quality of audio frequency can be significantly improved, the needs that people listen to far and near sound can be met simultaneously.
Description
Technical field
The utility model relates to hearing aid technology, especially a kind of multifunction wireless hearing aids.
Background technology
There is obstacle for hearing or need occasion that the sound of sound source is amplified, usually need to use hearing aids.
Traditional hearing aids has signal receiving end, digital to analog converter, loudspeaker and power supply etc., and generally wear the crowd of this kind of hearing aids when listening to voice signal remotely, definition is not high, poor effect.
Therefore, prior art needs to be improved and improves.
Summary of the invention
For overcoming the above-mentioned problems in the prior art, the purpose of this utility model is to provide one and listens to the remotely voice signal still good multifunction wireless hearing aids of effect.
The utility model realizes above-mentioned purpose by following technological means:
A kind of multifunction wireless hearing aids, comprise MCU, microphone, pick-up coil and loudspeaker, described microphone is connected with MCU, and described pick-up coil is connected with MCU, described MCU connects loudspeaker by a power amplification circuit, and described MCU has a Sound control channel switching module.
Compared with prior art, the beneficial effects of the utility model are: by the setting of microphone and pick-up coil, can significantly improve the quality of audio frequency, can meet simultaneously people to far and near sound listen to needs.
Accompanying drawing explanation
Accompanying drawing 1 is functional-block diagram of the present utility model.
In figure, each label respectively: (10) MCU, (20) microphone, (30) pick-up coil, (40) loudspeaker, (50) power amplification circuit, (60) Sound control channel switching module.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Refer to Fig. 1, a kind of multifunction wireless hearing aids of the utility model, comprise MCU10, microphone 20, pick-up coil 30 and loudspeaker 40, described microphone 20 is connected with MCU10, microphone 20 converts tones into the signal of telecommunication and forms first passage with this, realizes in-plant audio collection; Described pick-up coil 30 is connected with MCU10, pick-up coil 30 converts tones into the signal of telecommunication and forms second channel with this, realize remote audio collection, because atomic weak audio signal can gather by pick-up coil 30, therefore, through the process to signal, the clear sound being sent to user is effective; Described MCU10 connects loudspeaker 40 by a power amplification circuit 50, by loudspeaker 40, sound is sent to user, described MCU10 has a Sound control channel switching module 60, by this Sound control channel switching module 60, user sends passage bridge instruction by sound, thus the pattern realizing first passage and second channel switches, be convenient to user and use.
The above, only better enforcement of the present utility model, not any pro forma restriction is done to the utility model, any those skilled in the art may utilize above-mentioned technology contents to be changed or be modified to the Equivalent embodiments of equivalent variations, at this, allly do not depart from the technical solution of the utility model content, the any simple modification just done above embodiment according to technical spirit of the present utility model, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
