Embodiment Construction
[0007] Such as figure 1 As shown, a hearing aid, training and entertainment system 1 for the deaf-mute includes a transmitting unit 11 , a receiving unit 12 and an earphone 13 . The transmitting unit 11 includes a microphone and an amplifier 11a, a data memory 11b, an MP3 / MP4 / MP5 player 11c, and a digital wireless audio transmitter 11d. Strong anti-interference effect. The data memory 11b can be a built-in memory chip, or an external USB flash drive, SD card, etc. Training courseware or those used for entertainment are stored in the data memory in MP3, MP4 or MP5 format, and along with the play command, the audio (stereo) signal is transmitted wirelessly into the air through a digital wireless audio transmitter. The transmitter unit 11 has a built-in microphone and amplifier 11a. Therefore, in addition to audio signals, speech signals detected by the microphone and background noise signals detected by the microphone are also transmitted wirelessly into the air through the di...

The invention relates to a medical electronic auxiliary system, in particular to a hearing aid, training and entertainment system for deaf mutes. The hearing aid, training and entertainment system for the deaf mutes aims at the deaf mutes at all age groups. The hearing aid, training and entertainment system for the deaf mutes comprises a sending unit, a receiving unit and headphones. The sending unit comprises a microphone and amplifier, a data memorizer, an MP3 / MP4 / MP5 player and a digital wireless voice frequency sender. The receiving unit comprises a microphone and amplifier, a signal processor, a power amplifier, an amplitude-frequency regulator and a digital wireless voice frequency receiver. The sending unit is connected with the receiving unit in a digital wireless mode and two microphones are adopted for noise reduction. The headphones comprise a left sound track headphone and a right sound track headphone, at least two vibrator units are arranged inside the headphones, one vibrator unit drives to generate low-frequency vibration and sound signals, the low-frequency vibration and sound signals are sent to auditory nerves of the deaf mutes through skins or bones, the other vibrator unit drives to generate high-frequency vibration and sound signals, and the high-frequency vibration and sound signals are sent to the auditory nerves of the deaf mutes through air or eardrums.
Description
Technical field [0001] The invention relates to a medical electronic auxiliary system, in particular to a hearing aid, training and entertainment system for deaf-mute people of all ages. Background technique [0002] Generally, the medical electronic auxiliary systems for the deaf-mute are mainly hearing aids. Traditional hearing aids can be simplified into a sound amplifier, mainly including: microphone, preamplifier, postamplifier, earphone. Most deaf people may be able to perceive amplified sound signals, but some people, especially children who have been deaf since childhood, often do not understand what they hear. In this regard, periodic training is necessary. In addition, for deaf-mute people, on the one hand, they hope to communicate like normal people; entertainment effect. Traditional hearing aids are suitable for speech communication and not suitable for entertainment applications such as listening to music. The reason is that its earphones have a narrow freq...
