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

The invention discloses a charging box and a charging system for communicating with a wireless earphone, comprising: a second communication contact connected with the first communication contact of the wireless earphone put into the box; wherein, the first communication contact is connected with the wireless earphone The analog-to-digital conversion interface of the first control chip is connected; the analog communication circuit connected with the second communication contact; the communication trigger module for receiving the communication instruction representing the pre-implementation function of the wireless earphone; connected with the analog communication circuit and the communication trigger module The second control chip is used to control the analog communication circuit to output an analog signal representing the pre-implemented function when the wireless earphone is put into the box and receives a communication instruction, so that the first control chip receives the data signal converted from the analog signal After that, control the wireless headset to realize the pre-implementation function. It can be seen that the analog communication method of the present application reduces the cost of the wireless earphone and facilitates 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...
