Abstract

The invention discloses a method and Bluetooth earphone system for realizing a hearing aid function by a single Bluetooth chip. The method for realizing the hearing aid function by the single Bluetooth chip comprises the following steps: converting a sound source collected by a microphone MIC into a digital signal through AD conversion; then attaching the converted digital signal to an output loop; and outputting he converted digital signal through a speaker SPK. The invention adds the hearing aid function to the basic functions of calling and playing music of an ordinary Bluetooth earphone. The differences of the invention from the hearing aids, Bluetooth hearing aids and the like on the market are that: compared with the ordinary hearing aids, the Bluetooth is added, which can be used for calling and playing music; and the difference of the invention from the Bluetooth hearing aid is that the invention is implemented by using the single Bluetooth chip, and the cost is greatly reduced.

Description

technical field [0001] The invention discloses a bluetooth earphone, in particular to a method and a bluetooth earphone system for realizing a hearing aid function with a single bluetooth chip. Background technique [0002] Bluetooth headset is to apply Bluetooth technology to hands-free headsets, so that users can avoid annoying wires and talk easily in various ways. Since the advent of Bluetooth headsets, it has been a good tool for mobile business families to improve efficiency. However, ordinary bluetooth earphones usually only have a bluetooth call function, and the function is relatively single. High-end bluetooth earphones have the function of playing music, but it is still the basic function of bluetooth earphones. [0003] With the continuous development of technology and people's higher and higher requirements for quality of life, Bluetooth headsets that only have the functions of Bluetooth calls and music playback have long been unable to meet people's inner need...
