Loudspeaker, loudspeaker casing and manufacturing method of loudspeaker casing

Abstract

The invention provides a casing of a loudspeaker. The casing comprises a first housing and a reinforcing steel part, wherein the first housing is provided with a first accommodation space, the reinforcing steel part comprises a body and a supporting connecting plate which extends from the body, the reinforcing steel part and the first housing are formed integrally, the first housing comprises an accommodation hole and a cavity which is communicated with the first accommodation space, the body is arranged corresponding to the accommodation hole, one end of the supporting connecting plate is embedded inside the first housing, and the other end of the supporting connecting plate extends to a position of the cavity. In the casing of the loudspeaker, the integral reinforcing steel part is formed by an injection moulding technology, and the supporting connecting plate of the reinforcing steel part is directly embedded inside the first housing, so that the integral appearance is flat and attractive, the probability of corrosion damage of the reinforcing steel part is greatly reduced, and the reliability of a product is improved. Simultaneously, the invention also provides the loudspeaker using the casing and a manufacturing method of the casing.

Description

technical field [0001] The invention relates to a loudspeaker casing, a loudspeaker using the casing and a manufacturing method of the loudspeaker casing. Background technique [0002] With the development of consumer electronics products in the direction of thinner and lighter, various components that make up consumer electronics products also need to adapt to the trend of thinner and lighter, and micro speakers are no exception. [0003] The loudspeaker refers to the reciprocating movement of the diaphragm in the magnetic field to drive the air flow in or out to produce sound, and is widely used and installed on consumer electronics products. [0004] In addition to the mechanical system, the loudspeaker also needs to be provided with a housing for support and protection. In the known related technology, the speaker housing is covered with a plastic housing to cover the entire speaker internal structure, and the housing supports the vibration system and the magnetic circu...

AI Technical Summary

Problems solved by technology

[0014] However, the following defects still exist in the processing of the above-mentioned casing 11: because the support link 114 runs through the side wall 1113 of the first shell 111, after the exposed part of the support link 114 is cut off, the The cut marks formed on the surface of the side wall 1113 affect the appearance; and, because the cross-section of the support link 114 is also exposed in the air, this structure is easy to cause the reinforced steel body 113 to corrode and damage from the cross-section , more importantly, during use, because the speaker 1 is usually assembled with other electronic components at the same time, when it is in contact with an external circuit, an electrical connection is likely to occur and have a destructive effect on the speaker 1, reducing product reliability.
