Embodiment Construction
[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0033] figure 1 It is a structural schematic diagram of a wireless earphone charging system. Wherein, the wireless earphone may be a true wireless stereo (True Wireless Stereo, TWS) earphone. Such as figure 1 As shown, the charging system includes a first part of the circuit 100 located in the TWS earphone and a second part of the circuit 200 located in the charging box. The first part of the circuit 100 includes a first battery BAT1 , a first ...

The invention relates to a wireless earphone and a circuit thereof, a charging box and a circuit thereof, and a charging box upgrading method. The wireless headset circuit includes: a first battery; the first charging management unit performs charging management on the first battery and is provided with a charging end; the first detection unit detects that the voltage of the charging end is a first charging voltage or a second charging voltage greater than the first charging voltage; a first boost unit that is charged in advance by a second charging voltage; the first upgrading unit sends a pulse signal to the first boosting unit, and the pulse signal enables the first boosting unit to boost the charging end to a first voltage greater than the first charging voltage when the first detection unit detects that the voltage of the charging end is the first charging voltage, so that the charging box circuit stops outputting the first charging voltage; therefore, the first upgrading unit sends a program code for upgrading the charging box to the charging box circuit through the charging end. The charging box can be upgraded without being connected with special equipment, the circuit structure is simple, and the cost can be reduced.
Description
technical field [0001] The invention relates to the technical field of earphones, in particular to a wireless earphone and its circuit, a charging box and its circuit, and a method for upgrading the charging box. Background technique [0002] Compared with wired earphones, wireless earphones have the advantages of being convenient to carry and use, so they are more and more popular. With the continuous development of technology, it is inevitable to upgrade the charging box. The traditional solution is to upgrade the charging box by connecting the charging box with a special device, so that the user needs to go to the maintenance point to upgrade, which makes the upgrading operation very inconvenient. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned technical problems and provide a wireless earphone and its circuit, a charging box and its circuit, and a method for upgrading the charging box. The charging box can be ...
