Embodiment
Now with embodiment, the utility model is further illustrated by reference to the accompanying drawings.
embodiment 1
As a specific embodiment, see Fig. 1, a kind of bluetooth hearing aids of the present utility model, comprise the sound acquisition module for receiving voice signal, by voice signal amplifying signal amplification module, complete the Micro-processor MCV changed between voice signal and the signal of telecommunication, for the power module of powering, realize bluetooth communication bluetooth module and for the voice output module by voice output, the output of sound acquisition module is connected to the input of signal amplification module, the output of signal amplification module is connected to the input of Micro-processor MCV, power module is connected to the power end of Micro-processor MCV, bluetooth module and Micro-processor MCV are set up and are bi-directionally connected, the output of bluetooth module is connected to the input of voice output module, wherein, bluetooth module comprises Bluetooth chip, charhing unit, volume adjustment unit and signal amplification unit, and charhing unit, volume adjustment unit, signal amplification unit are all electrically connected to Bluetooth chip.
In order to prevent amplifier distortion (harmonic distortion, intermodulation distortion), the signal amplification unit of bluetooth module and signal amplification module share a signal amplifier and realize.
embodiment 2
In the present embodiment, this bluetooth hearing aids is except each module of embodiment 1, and rise and also comprise memory module and display module, this memory module and Micro-processor MCV are bi-directionally connected, and when user is by bluetooth module transmission data, stores by memory module.This display module is connected to the output of Micro-processor MCV, for showing hearing aids operating state and parameter.
Fig. 3 is the circuit theory diagrams of the bluetooth hearing aids of embodiment 1 of the present utility model, and it mainly comprises Bluetooth chip BC213159A, charhing unit CN3052, hearing aid chips SA3286.Bluetooth chip BC213159A can carry out bluetooth to being frequently connected with mobile phone, computer, TV etc., bluetooth output signal (J1, K1) connects the input of hearing aid chips SA3286, after amplifying through hearing aid chips SA3286, export to loudspeaker (voice output module).So both can realize the voice signal of hearing aids own to amplify, also can accept separately the signal of mobile phone, computer, TV.
In order to simplify circuit structure, the volume adjustment unit of bluetooth module adopts SW-PB key switch to realize, and see Fig. 3, in the present embodiment, this volume adjustment unit comprises key switch SW1 and key switch SW2.This volume adjustment unit also adjusts for the volume of whole hearing aids, and that is the key switch SW1 of this volume adjustment unit and key switch SW2 and hearing aids share.Key switch SW1 and key switch SW2 is external physics volume button.The external physics volume button of Bluetooth chip BC213159A and hearing aid chips SA3286 shares, when specifically using, the short volume plus-minus by controlling hearing aid chips SA3286, the long volume plus-minus controlling Bluetooth chip BC213159A by (being such as more than or equal to 3 seconds).
In order to prevent amplifier distortion (harmonic distortion, intermodulation distortion), the signal amplification unit of bluetooth module and signal amplification module share a signal amplifier and realize, and signal amplifier adopts the signal amplification module of hearing aid chips SA3286 to realize.Because the measurement sound pressure level of regulation is 70dB, the distortion numerical value thus now recorded is less, does not represent the distortion when large input acoustic pressure pole of bluetooth hearing aids also little.Because when input signal is at medium and low middling, linearity of amplifier amplifies, at this moment undistorted generation.When input signal is not too large, signal is less by peak clipping, and the harmonic distortion of generation is also little, also affects not quite the understandability of speech.But when input signals are large, because peak clipping degree strengthens, harmonic distortion can be very large, also greatly declines to the understandability of speech.The measurement sound pressure level of regulation is that 70dB is mainly generally 60 ~ 70dB based on the sound intensity heard during verbal communication.But when hearing aid user listens the sound of oneself particularly to make a phone call, because sound source distance microphone is comparatively near, the input sound intensity of hearing aids may have 80 ~ 90dB, and at this moment the distortion of hearing aids is just likely larger.Although the distortion that frequent hearing aid is measured is very little, sounds and having a husky voice, is exactly this reason.Therefore weigh the tonequality quality of hearing aids, only can not see distortion during input 70dB sound pressure level.In the present embodiment, adopt hearing aid chips SA3286 chip and peripheral circuit thereof, coordinate Bluetooth chip BC213159A to achieve good circuit optimization, decrease the distortion of the sound pressure level of each grade.
In addition, in order to save power supply, this bluetooth module also comprises switch element, this switch element is electrically connected to Bluetooth chip, in the present embodiment, it adopts external physics starting key (RESET) to realize, and presses this RESET button thus opens or close bluetooth module.Meanwhile, the conveniently switching of the external program of whole hearing aids, this switch element also switches use as the program of bluetooth hearing aids simultaneously.Concrete shortly press RESET button in use, the program realizing hearing aid chips SA3286 switches, the long switching on and shutting down by (being such as more than or equal to 3 seconds) control Bluetooth chip BC213159A.
Consult Fig. 3, conveniently by this chip external equipment, bluetooth module also comprises bluetooth and turns serial port unit, and bluetooth turns serial port unit and Bluetooth chip is electrically connected, this bluetooth turns serial port unit and adopts bluetooth to turn serial port chip realization, and such as model is BMX-02/03 family chip.
Meanwhile, see Fig. 3, in the present embodiment, the power module of power supply adopts lithium battery power supply, is charged the battery by CN3052 chip, then by powering to after HX1001 chip voltage hearing aid chips SA3286.
Bluetooth hearing aids of the present utility model, improve the electronic circuit of existing bluetooth hearing aids, bluetooth earphone function and function of hearing aid with effective integration, and parameter programmable can be realized, the adjustment of physics volume, physical procedures switch; Meanwhile, bluetooth hearing aids also can keep the original function of bluetooth earphone, chargeable, Bluetooth data transfer, the adjustment of physics volume etc.Above-mentioned bluetooth hearing aids, when having communication signal in the external world, be switched to bluetooth earphone pattern carry out telephone receiving by bluetooth module, when not having communication signal, this device is in hearing aid state, convenient for users to use.
Although specifically show in conjunction with preferred embodiment and describe the utility model; but those skilled in the art should be understood that; not departing from the spirit and scope of the present utility model that appended claims limits; can make a variety of changes the utility model in the form and details, be protection range of the present utility model.
