Embodiment 1

[0036] This embodiment provides a data communication system for simultaneous detection of multiple earphones, including a sending end, an air channel and a receiving end, the sending end sends data to the receiving end through the channel; the sending end includes a signal source and a modulator and a speaker, the source, the modulator and the speaker are connected in sequence; the receiving end includes a microphone, a demodulator and a sink; the microphone, the demodulator and the sink are connected in sequence.

[0037] The data communication system in this embodiment can realize online testing of multiple earphone devices at the same time, and the information source includes multiple earphone devices, and different earphone devices have different device numbers.

Embodiment 2

[0039] In this embodiment, the data communication system described in Embodiment 1 is used to realize a simultaneous detection method for multiple earphones, and the method includes the following steps:

[0040] S1, using multiple earphone devices to build a data communication system, including a sending end, a channel, and a receiving end; the sending end includes a source, a modulator, and a speaker, and the source, the modulator, and the speaker are connected in sequence; The receiving end includes a microphone, a demodulator and a sink; the microphone, the demodulator and the sink are connected in sequence.

[0041] In this embodiment, the channel is the air between the sending end and the receiving end, and the channel noise is the channel noise.

[0042] S2. Generate different source data according to different device numbers; select different source coding methods to encode the generated source data, and then perform channel coding on the coded source data.

[0043] So...

Abstract

The invention discloses a sound wave data communication system and method for realizing simultaneous detection of multiple earphones, and relates to the technical field of earphone detection. The datacommunication system comprises a sending end, a channel and a receiving end, wherein the sending end comprises an information source, a modulator and a loudspeaker which are connected in sequence; and the receiving end comprises a microphone, a demodulator and an information sink which are sequentially connected. The detection method comprises the steps of the sending end generating information source data, encoding the information source data and a channel and then transmitting the data to a modulator; modulating the coded channel data to generate a left channel modulated digital signal anda right channel modulated digital signal; playing the left and right channel modulated digital signals and recording by adopting a microphone; performing data processing on the recorded data, and finally obtaining information sink data; comparing the result of the information sink data with the result of the information source data and judging the earphone detection result. Through the scheme of the invention, tedious detection steps before a user uses the earphone can be solved, more time is saved, the operation is convenient, and the accuracy is high.

Description

technical field [0001] The invention relates to the field of earphone detection, in particular to an acoustic wave data communication system and method for realizing simultaneous detection of multiple earphones. Background technique [0002] At present, computers and electronic devices have penetrated all aspects of daily life, and earphones are becoming more and more widely used as an accessory electronic device. Almost every computer or mobile device needs to be equipped with earphones, and some environments require earphones even more, such as voice In classrooms, conference sites, etc., before using the equipment, it is impossible to determine whether the earphones are in good condition. Only the user will find that the earphones are damaged during use. At this time, repair or replacement has affected the continuity of equipment use, and even affects the meeting. Or voice courses, the user experience is extremely poor. However, if one-by-one inspection is carried out be...
