Loudspeaker box

Abstract

The invention provides a loudspeaker box, which comprises a shell with an accommodating space and a sound production monomer, and is characterized in that the shell comprises a plastic part and a reinforcing rigid body which is arranged on the plastic part in an injection molding manner, and the plastic part comprises a bottom wall which is connected with the reinforcing rigid body and a retainingwall which is connected with the bottom wall. The loudspeaker box further comprises a soldering lug for electrically connecting the sound production single body with an external circuit, and the soldering lug comprises a main body part, a first electric connection part extending from the main body part to the outside of the accommodating space, and a second electric connection part extending fromthe main body part and electrically connected with the sound production single body. The plastic part further comprises an enclosing wall extending from the bottom wall to the position far away fromthe reinforcing rigid body, the enclosing wall and the blocking wall are spaced by a certain distance and surround the main body part, and the enclosing wall and the reinforcing rigid body are bondedthrough glue. The loudspeaker box is low in cost, simple to assemble and high in 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. Therefore, speaker boxes for playing sound are widely used in current smart mobile devices. [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
