Embodiment 1

[0070] The microphone of the earphone 3 is one.

[0071] Such as Figure 4 Shown, a kind of environmental sound monitoring parameter calibration method, based on the above-mentioned environmental sound monitoring parameter calibration system, the method comprises the following steps:

[0072] 1) Place the earplug of earphone 3 on the artificial ear canal of dummy head 2;

[0073] 2) The earphone 3 communicates with the control operation module 4, and makes the earphone 3 enter the calibration mode;

[0074] 3) The control operation module 4 controls the audio sound module 1 to play the calibration audio;

[0075] 4) The microphone on the earphone 3 collects the calibration audio and converts it into an analysis audio, and sends the analysis audio to the control operation module 4;

[0076] 5) The control operation module 4 analyzes and calculates the analyzed audio to obtain calibration parameters, and sends the calibration parameters to the earphone 3 for storage.

[0077...

Embodiment 2

[0104] The earphone 3 has two earplugs, and a microphone is arranged in each earplug. The above analysis audio is divided into left ear analysis audio and right ear analysis audio.

[0105] Such as Figure 9 Shown, a kind of environmental sound monitoring parameter calibration method, based on the above-mentioned environmental sound monitoring parameter calibration system, the method comprises the following steps:

[0106] 1) Place the earplug of earphone 3 on the artificial ear canal of dummy head 2;

[0107] 2) The earphone 3 communicates with the control operation module 4, and makes the earphone 3 enter the calibration mode;

[0108] 3) The control operation module 4 controls the audio sound module 1 to play the calibration audio;

[0109] 4) The two microphones on the earphone 3 respectively collect the calibration audio and convert it into the left ear analysis audio and the right ear analysis audio, and send the left ear analysis audio and the right ear analysis audi...

Abstract

The invention discloses a system and method for calibrating environmental sound monitoring parameters. The system includes an audio sounding module, an artificial head, an earphone and a control operation module. The earphone earplugs are placed on the artificial ear canal, the audio sounding module is electrically connected to the control operation module, and the control operation module Communicate with the headset. The method includes the following steps: 1) placing the earplug of the earphone on the artificial ear canal of the dummy head; 2) communicating the earphone with the control operation module, so that the earphone enters the calibration mode; 3) the control operation module controls the audio sound module to play the calibration audio ; 4) The microphone collects the calibration audio and converts it into analysis audio; 5) The control operation module analyzes and calculates the analysis audio to obtain calibration parameters, and sends the calibration parameters to the earphone for storage. The invention can calibrate the environmental sound monitoring parameters, so that the user can also monitor the environmental sound while wearing earphones; the invention also has a hearing aid function and improves the practical performance of the earphones.

Description

technical field [0001] The invention relates to the technical field of earphones, in particular to a system and method for calibrating environmental sound monitoring parameters. Background technique [0002] Ambient sound mainly refers to the general term of various sounds around the human ear. For users who wear earphones and other types of electronic products, environmental sound monitoring is very necessary, because human ears are blocked, and they are not sensitive to outside sounds when listening to music, and cannot normally hear other people's speech and traffic on the road. Sounds such as car alarms are likely to bring various troubles and dangers. It is very passive to take off the earphones and listen again. The monitoring of ambient sound can solve the above problems very well. [0003] For electronic products, because it involves the assembly of incoming structural materials and the differences in electronic components, etc., it is impossible to guarantee the c...
