Problems solved by technology

Due to the load on the human ear, hearing aids cannot be made too large, otherwise the human ear will be overwhelmed. On the other hand, if the hearing aid is made slightly larger, it may cause discrimination for the wearer. It may be made small, which limits the ability of its signal processing system to not be too strong, and the battery also uses high-end metal-air batteries, and the energy consumption should not be too high. Such a compromise makes the hearing aid effect very limited, often Severe noise, hearing distortion and other problems

Embodiment 1

[0015] Embodiment 1: The earphone is connected to the hearing aid terminal by wire.

[0016] In this embodiment, the hearing aid terminal 6 is a mobile phone.

[0017] Such as figure 1 As shown, there are two earphones, and each earphone is composed of a microphone 1 and a micro-speaker 2, and an isolation cavity 3 is provided between the microphone 1 and the micro-speaker 2. The signal output end of the microphone 1 is connected to the signal input end of the sound signal processing unit 4 through the ADC module, and the signal output end of the sound signal processing unit 4 is connected to the WeChat speaker 2 through the DAC module. A sound measurement module 5 is provided between the sound signal processing unit 4 and the DAC module. The sound signal processing unit 4, the ADC module, the DAC module, and the sound measurement module 5 are all located in the hearing-aid terminal 6, and the hearing-aid terminal 6 is wired to the earphone.

[0018] The microphone 1 collec...

Embodiment 2

[0019] Embodiment 2: The earphone is wirelessly connected to the hearing aid terminal.

[0020] In this embodiment, the hearing aid terminal 9 adopts a special hearing aid device.

[0021] The sound signal processing unit 7 and the sound measurement module 8 are located in the hearing aid terminal 9, the ADC module and the DAC module are arranged on the earphone, the hearing aid terminal 9 is wirelessly connected to the earphone, and both the earphone and the hearing aid terminal 9 are provided with a wireless sending module and Wireless receiving module. On the earphone, the signal output end of the ADC module is connected to the wireless sending module through the encoding module, and the signal output end of the wireless receiving module is connected to the DAC module through the decoding module; on the hearing aid terminal 9, the signal output end of the wireless receiving module is connected to the sound signal processing unit 7 , the signal output end of the sound signa...

Abstract

The invention relates to a hearing aid which comprises microphones, micro loudspeakers and a sound signal processing unit. The hearing aid is characterized in that the microphones and the micro loudspeakers form earphones, and a separation cavity is formed between each microphone and the corresponding micro loudspeaker; the hearing aid further comprises a hearing aid terminal, the sound signal processing unit is arranged in the hearing aid terminal, the signal output ends of the microphones are connected with the signal input end of the sound signal processing unit through an ADC module, and the signal output end of the sound signal processing unit is connected with the micro loudspeakers through a DAC module.

Description

technical field [0001] The invention relates to a hearing aid device. Background technique [0002] Existing hearing aids are composed of microphones, micro-speakers, sound signal processing units, batteries, and the like. Due to the load on the human ear, hearing aids cannot be made too large, otherwise the human ear will be overwhelmed. On the other hand, if the hearing aid is made slightly larger, it may cause discrimination for the wearer. It may be made small, which limits the ability of its signal processing system to not be too strong, and the battery also uses high-end metal-air batteries, and the energy consumption should not be too high. Such a compromise makes the hearing aid effect very limited, often Severe noise, hearing distortion and other problems occur. Contents of the invention [0003] The object of the present invention is to provide a hearing aid device which is easy to use and effectively improves the hearing aid effect. [0004] The technical sch...
