Embodiment 1

[0022] Such as figure 1 As shown, a novel audio conversion device of the present invention includes a sound signal transmitter 4, and a novel audio conversion device also includes a microphone interface 1, an audio interface 2, and a Bluetooth interface 3, and the three interfaces are commonly connected to the audio switcher Above, the output end of the audio switcher is sequentially connected to a filter, an analog-to-digital converter, a DSP processor, and a digital-to-analog converter, and the output end of the digital-to-analog converter is connected to the sound signal transmitter 4 .

[0023] During use, when the input signal is an audio signal input by a microphone, the microphone device is connected to the microphone interface 1 of the novel audio conversion device, and then the hearing aid is connected to the sound signal transmitter 4 of the new audio conversion device, When the user speaks to the microphone, the hearing aid will send out a high-quality audio signal ...

Embodiment 2

[0025] This embodiment makes the following further limitations on the basis of Embodiment 1: the audio switcher adopts automatic patrol technology, and adopts XUNWEI 8-in 1-out audio switcher. The sound signal transmitter 4 uses a bluetooth transmitter, and adopts a bluetooth audio transfer transmitter whose model is RDT1202. The filter adopts a low-pass filter, and adopts a low-pass power filter whose model is YB11E1-10A-Q. The DSP processor has a built-in noise suppression algorithm, adopts ADAU1452 digital audio processor, and has a built-in multi-channel Wiener filter noise reduction algorithm.

Abstract

The invention discloses a novel audio conversion device, which relates to audio converters. The novel audio conversion device comprises a sound signal transmitter and further comprises a microphone interface, an audio interface, a Bluetooth interface, and an audio switcher, a filter, an analog-to-digital converter, a DSP and a digital-to-analog converter connected orderly; the microphone interface, the audio interface and the Bluetooth interface are jointly connected with the filter, and the digital-to-analog converter is connected with the sound signal transmitter. The novel audio conversiondevice has the characteristics of being compatible to various input modes and enabling the existing hearing aid with a Bluetooth audio converter to be capable of being matched with more devices; by multiple noise reduction through the filter and the DSP, quality of voice is improved, and people with hearing disorders are helped to understand semantics better; through an audio switcher automatic tour round technology, audio input is automatically identified and conductive separately, and thus, the novel audio conversion device is more convenient and efficient to use.

Description

technical field [0001] The invention relates to an audio converter, in particular to a novel audio conversion device. Background technique [0002] At present, there are more and more hearing-impaired people in our country, mainly including the elderly and mildly deaf patients. As a small loudspeaker to help the hearing-impaired, hearing aids solve the problem of the hearing-impaired. A hearing aid is a small loudspeaker that amplifies the originally inaudible sound, and then uses the residual hearing of the hearing-impaired to send the sound to the auditory center of the brain so that the sound can be felt. It is mainly composed of five parts: microphone, amplifier, earphone, power supply and volume control. Hearing aids are divided into air conduction hearing aids and bone conduction hearing aids according to the conduction method; according to the use method, they are classified into box type, glasses type, hairpin type, behind-the-ear type, in-ear type, ear canal type, ...
