speaker box

Abstract

The present invention provides a loudspeaker box, which includes a casing with a receiving space and a sounding unit, the casing includes a plastic part and a reinforcing rigid body injected into the plastic part, and the plastic part includes the reinforcing rigid body A connected bottom wall and a retaining wall connected to the bottom wall. The speaker box also includes a soldering piece for electrically connecting the sounding unit with an external circuit, and the soldering piece includes a main body, a first electrical connection portion extending from the main body to the outside of the receiving space, and a first electrical connecting portion extending from the main body The second electrical connection part extends from the bottom wall and is electrically connected to the sounding unit. The plastic part also includes a surrounding wall extending from the bottom wall away from the reinforcing rigid body. The surrounding wall is separated from the retaining wall by a certain distance. distance from and surround the main body, and the wall and the reinforced rigid body are bonded by glue. The loudspeaker box of the invention has low cost, simple assembly and high assembly stability.

Description

【Technical field】 [0001] The invention relates to the field of sound and electricity, in particular to a speaker box applied to portable electronic products. 【Background technique】 [0002] With the advent of the mobile Internet era, the number of smart mobile devices continues to rise. Among the many mobile devices, the mobile phone is undoubtedly the most common and portable mobile terminal device. At present, the functions of mobile phones are extremely diverse, one of which is the function of high-quality music.

[0003] A speaker box in the related art includes a housing, a sounding unit accommodated in the housing, and a flexible circuit board for connecting the sounding unit and an external circuit for supplying power to the sounding unit. The flexible circuit board is fixed to the housing by welding, and the assembly process includes processes such as fitting, soldering, and...

AI Technical Summary

Problems solved by technology

The flexible circuit board is fixed to the housing by welding, and the assembly process includes processes such as fitting, soldering, and notch glue. The assembly process is complicated and requires processes such as hot spots and pressure maintaining; due to the small size of the flexible circuit board, The assembly accuracy is poor, and it is necessary to apply notch glue to the outlet groove after assembly. If the notch glue is not applied in place, there will be a risk of air leakage in the outlet groove; at the same time, the price of the flexible circuit board is relatively expensive
