Charging box communicating with wireless earphone, and charging system

Abstract

The invention discloses a charging box communicating with a wireless earphone, and a charging system. The charging box comprises a second communication contact connected with a first communication contact of the wireless earphone after entering the box. The first communication contact is connected with an analog-to-digital conversion interface of a first control chip of the wireless earphone. Theanalog communication circuit is connected with the second communication contact. The communication triggering module is used for receiving a communication instruction for representing a pre-implementation function of the wireless earphone. The second control chip is connected with the analog communication circuit and the communication trigger module. The control circuit is used for controlling theanalog communication circuit to output an analog signal representing the pre-implementation function when the wireless earphone enters the box and a communication instruction is received, so that thefirst control chip controls the wireless earphone to realize the pre-implementation function after receiving a data signal converted from the analog signal. Therefore, the analog communication mode of the application reduces the cost of the wireless earphone, and is beneficial to the miniaturization design of the wireless earphone.

Description

technical field [0001] The invention relates to the field of wireless earphone charging, in particular to a charging box and a charging system for communicating with a wireless earphone. Background technique [0002] With the development of wireless communication technology, wireless earphones are more and more widely used. Among the wireless earphone products, TWS (True Wireless Stereo, True Wireless Stereo) wireless earphones are relatively intelligent products, which are usually equipped with a charging box with storage and charging functions. At present, communication between the charging box and the wireless earphone is usually designed to complete some specific functions of the wireless earphone, thereby enhancing user experience. [0003] In the prior art, digital communication is mostly used to complete information transmission between the charging box and wireless earphones. This digital communication method requires a complete digital communication circuit to be b...

Problems solved by technology

[0003] In the prior art, digital communication is mostly used to complete information transmission between the charging box and wireless earphones. This digital communication method requires a complete digital communication circuit to be built on both the charging box and the wireless earphones, resulting in relatively high cost for the wireless earphones. High; moreover, the components of the digital communication circuit will occupy part of the space of the circuit board of the wireless earphone, which is not conducive to the miniaturization design of the wireless earphone
