Earphone and its assembly method

Abstract

The invention provides an earphone and an assembly method thereof. The earphone includes a battery module, a main board, a first electrical connection element, a loudspeaker module and a second electrical connection element; A battery element used for power supply in a storage space; the speaker module is fixedly connected to the casing and together with the casing to form a second storage space, the main board is located in the second storage space; the main board is fixedly stored in the second storage space; the first The electrical connection element extends from the first storage space through the housing to the second storage space, one end of the first electrical connection element is electrically connected to the battery element, and the other end extends into the second storage space to be electrically connected to the main board; The two electrical connection elements are fixed on the main board and electrically connect the main board with the speaker module. Compared with the related art, the earphone of the present invention has fewer welding spots, simple circuit structure and high assembly efficiency.

Description

technical field [0001] The invention relates to the technical field of an electroacoustic conversion device, in particular to an earphone. Background technique [0002] With the advent of the mobile Internet era, the number of smart mobile devices continues to rise. Among them, TWS wireless earphones have been favored by consumers since their launch, and their demand has also increased significantly year by year. [0003] In the related art, the TWS wireless earphone includes a housing with a first storage space, battery elements accommodated in the first storage space are respectively fixed on a main board and a speaker box outside the housing, and the main board relies on cables and batteries wound around the housing. The components form an electrical connection, the cable needs to be welded to the solder spot of the main board, and the speaker module and the main board also need to be welded to form an electrical connection between the two. [0004] The size is getting ...

AI Technical Summary

Problems solved by technology

[0004] The size is getting smaller and more functions, therefore, various circuit connections and control relationships are also more complicated, which leads to more soldering of circuit boards, complicated cable winding, difficult production and assembly, and sometimes requires glue to fix, and then Poor product consistency and reduced reliability during use

[0005] However, in the earphones of the related art, due to the complexity of various circuit connections and control relationships, there are many solder joints to be welded, and the cable winding is complicated, thereby making the circuit structure complicated; in addition, during assembly, due to too many solder joints, Many times of welding are required, which seriously affects the assembly production efficiency of TWS wireless earphones
