Communication method, charging box, wireless earphone and computer storage medium

Abstract

The invention discloses a communication method which is characterized in that the communication method is applied to a charging box, and the communication method comprises the following steps: building a carrier communication channel based on a first contact and a second contact after the first contact of the charging box is connected with the second contact of a wireless earphone; modulating a first parameter of a carrier signal of the carrier communication channel according to to-be-sent data; and demodulating a second parameter of the carrier signal to obtain data sent by the wireless earphone, the first parameter being at least one of an amplitude, a frequency and a phase, or the second parameter being an amplitude, the first parameter being at least one of a frequency and a phase. Theinvention also discloses a communication method, a charging box, a wireless earphone and a computer storage medium. Full duplex communication between the charging box and the wireless earphone is realized through a single contact, and the cost is reduced while the data transmission rate is improved.

Description

technical field [0001] The invention relates to the technical field of earphone communication, in particular to a communication method, a charging box, a wireless earphone and a computer storage medium. Background technique [0002] The charging box of the True Wireless Stereo (TWS, True Wireless Stereo) headset needs to communicate independently with the left and right headsets to achieve better charging control and functional applications in other scenarios. [0003] In the prior art, the physical connection between the charging box and the earphone is often realized by connecting contacts (Pogo pins). If half-duplex communication is realized through a single communication contact, that is, the charging box and the earphone only communicate through a single line, and data can only be transmitted in one direction during the same period of time, making the data transmission rate lower; Line full-duplex communication can increase the data transmission rate, but due to the in...

Problems solved by technology

If half-duplex communication is realized through a single communication contact, that is, the charging box and the earphone only communicate through a single line, and data can only be transmitted in one direction during the same period of time, making the data transmission rate lower; Line full-duplex communication can increase the data transmission rate, but due to the increase in the number of communication contacts, it will also increase the complexity of the product structure and increase the manufacturing cost. Therefore, the existing communication methods cannot take into account both high data transmission rate and manufacturing cost
