Abstract
The utility model provides a wireless microphone of a hearing aid. The wireless microphone of the hearing aid comprises a wireless transmitting device and a wireless receiving device. The wireless transmitting device comprises an MEMS microphone used for converting voice signals into electrical signals, an MCU transmitting controller used for processing the electrical signals and transmitting the electrical signals to an infrared transmitting chip, and the infrared transmitting chip. The wireless receiving device comprises an infrared receiving chip, an MCU receiving controller used for processing signals of the infrared receiving chip and transmitting the signals to a hearing aid module, and the hearing aid module. The infrared transmitting chip is in communication connection with the infrared receiving chip. The carrier wave of the wireless microphone is infrared light, the frequency of the infrared light is above 3G, and the frequency of the infrared light is much higher than that of a common wireless system, so that the radio frequency is not occupied, and interference is avoided; the wireless microphone is small in size and convenient to carry; in addition, the wireless microphone is creatively applied to the field of the hearing aid, the quality of audio acquisition is obviously improved, and the wireless microphone is suitable for the elderly to hear high-fidelity sound.
Description
Technical field
The utility model relates to hearing aids field, especially relates to a kind of wireless hearing aids microphone.
Background technology
Along with social development, wireless advantage progressively manifests, the development of wireless telecommunications is very fast, and people for this noun of wireless microphone not strange, for example bar, KTV, meeting room, concert, program hosting etc. place, in these places, wireless microphone has seemed of crucial importance.
Also not having when popular at wireless microphone, is cable microphone at that time, cable microphone distance limit its development, and cumbersome be that cable microphone must be to couple together with connecting line and Karaoke, effect device, conference system, just can send voice.And wireless microphone has replaced and has connected with connecting line, adopt the way of the former black and white television set tuner of picture, realize the connection of wireless microphone and receiver, thereby make wireless microphone easy to use.In certain space, can move anywhere or anytime and send voice, but the use frequency range of wireless microphone is generally 200-700 million, and still have the following disadvantages in use: 1, need to take radio frequency, before installation, need to regulate the frequency of reflector and receiver, it is not too convenient to use; 2, be subject to external radio frequency, produce noise; 3, between uniform machines, phase mutual interference is large; 4, reflector volume is large, and it is not too convenient to carry.
Meanwhile, common hearing aids is all only to have a receiving equipment at present, i.e. hearing aids chip+earphone is worn the ear barrier patient of this hearing aids in the time of the voice signal (as the audio amplifier signal of microphone after amplifying) of listening at a distance, often poor effect.
Utility model content
The utility model object is for the existing above-mentioned technical problem of prior art, and a kind of wireless hearing aids microphone is provided.
A kind of wireless hearing aids microphone, comprise wireless transmission device and radio receiver, described wireless transmission device comprises for voice signal being converted to the microphone of the signal of telecommunication, for the treatment of the signal of telecommunication and is sent to MCU transmit control device and the infrared emission chip of infrared emission chip, described radio receiver comprises infrared receiving chip, receives controller and hearing aids module for the treatment of infrared receiving chip signal the MCU that is sent to hearing aids module, and described infrared emission chip communicates to connect with infrared receiving chip.
Preferably, described hearing aids module comprises the hearing aids chip for the signal of telecommunication is processed and the signal of telecommunication after treatment is converted to the hearing aid earphone of voice signal.
Preferably, described microphone adopts the MEMS microphone that numeral output is provided.
Compared with prior art, the utility model carrier wave is infrared ray to the utility model, and its frequency is more than 3G, high more a lot of than common wireless system, do not take radio frequency, can not produce interference, be difficult for producing disturbing wave yet, the interference of not forgiving between similar, volume is little, easy to carry; Innovation quotes wireless microphone in hearing aid field, obviously improves the quality of audio collection, is suitable for the sound source of the elderly's hearing aid high-fidelity.
Accompanying drawing explanation
Fig. 1 is the theory diagram of wireless hearing aids microphone described in the utility model.
Embodiment
Feature of the present utility model and advantage will be elaborated by reference to the accompanying drawings by embodiment.
As shown in Figure 1, a kind of wireless hearing aids microphone, comprise wireless transmission device and radio receiver, described wireless transmission device comprises MEMS microphone for voice signal being converted to the signal of telecommunication, for the treatment of the signal of telecommunication and be sent to MCU transmit control device and the infrared emission chip of infrared emission chip, described radio receiver comprises infrared receiving chip, receives controller and hearing aids module for the treatment of infrared receiving chip signal the MCU that is sent to hearing aids module, and described infrared emission chip communicates to connect with infrared receiving chip.Described hearing aids module comprises the hearing aids chip for the signal of telecommunication is processed and the signal of telecommunication after treatment is converted to the hearing aid earphone of voice signal.
Operation principle of the present utility model is: sound is changed into the signal of telecommunication by microphone, then pass the signal to MCU transmit control device, transmit signal to infrared emission chip by MCU transmit control device again, infrared emission chip will be converted into infrared ray after Signal coding, the infrared receiving chip receiving infrared-ray of radio receiver, changes into the signal of telecommunication by infrared ray, then the signal of telecommunication is sent to MCU reception controller, receive controller by MCU again and be sent to hearing aids, signal is changed into sound by hearing aids.
Specific embodiment described herein is only to the explanation for example of the utility model structure.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
