AI Technical Summary

Problems solved by technology

Due to the existence of the gap, when the upper shell and the lower shell are connected, for example, during ultrasonic welding, the lower shell will shake in the upper shell, resulting in undesirable phenomena such as tilting of the lower shell assembly and unstable ultrasonic welding.

Abstract

The invention discloses a speaker shell and a speaker module. The shell comprises a first shell and a second shell which are adjacent to each other; the first shell includes a first side wall part, and an open end is formed at one end, close to the second shell, of the first shell; the second shell is provided with a second side wall part extending towards the direction of the first shell; the second shell is covered on the open end; at least a part of the second side wall part is located below the end surface of the open end and is located at the inner side of the first side wall part; the first shell and the second shell are fixed together through ultrasonic welding; and a plurality of stop pieces for defining the position of the second shell are provided on the second side wall part and / or the first side wall part.

Description

technical field [0001] The present invention relates to the technical field of electro-acoustic conversion, and more particularly, to a loudspeaker shell and a loudspeaker module. Background technique [0002] Existing loudspeaker casings usually include an upper casing and a lower casing. The upper shell and the lower shell are snapped together. An accommodation space is formed inside the two. For example, part of the upper shell is located inside the lower shell to form a partial overlap. The speaker unit is installed in the accommodation space. The upper and lower shells are held together by ultrasonic welding. Under normal circumstances, limited by machining accuracy, there will be a certain gap between the upper shell and the lower shell. Due to the existence of the gap, when the upper shell and the lower shell are connected, for example, during ultrasonic welding, the lower shell will shake in the upper shell, resulting in undesirable phenomena such as tilting of ...
