Description

Loudspeaker shell and loudspeaker module

Technical Field

The utility model relates to the technical field of electroacoustic converters, in particular to a loudspeaker shell and a loudspeaker module.

Background

The speaker module includes speaker shell and locates the speaker monomer in the speaker shell, and speaker shell is injection moulding generally, and the bad problem that appears in the injection moulding process of speaker shell can sometimes lead to speaker module complete machine equipment to interfere, the problem such as gas leakage influences speaker acoustic performance.

Specifically, in the injection molding process of the existing loudspeaker shell, because the loudspeaker shell is injected into a mold through high temperature and high pressure after hot melting of plastic particles, and finally is cooled and molded, hot melt colloid is injected into a pouring port of an injection molding machine in the injection molding process, in the final molding process, the temperature cannot be reduced so quickly, the pouring port is in a high temperature state in a short time, when the pouring port is disconnected, the colloid part contacted with the pouring port is still in a hot melting semi-solidification state, at the moment, the hot melt part can pull out a section of colloid towards a separation surface, so that a section of redundant colloid exists at the pouring port of the loudspeaker shell, the appearance of the whole is influenced, and meanwhile, the colloid possibly has interference influence when being assembled with the whole electronic equipment, even the tightness of the whole machine is influenced, and the acoustic performance is influenced due to the influence of the leakage of the loudspeaker.

Disclosure of Invention

Example 1

Referring to fig. 1 to 3, a first embodiment of the present utility model is as follows: the loudspeaker housing is formed by an injection molding process.

The loudspeaker shell comprises a top wall 1 and a peripheral wall 2 arranged along the edge of the top wall 1, wherein the exposed surface of the top wall 1 is a first surface 11, the peripheral wall 2 is provided with an exposed second surface 21, a glue containing platform 22 is arranged on the second surface 21, and the glue containing platform 22 is communicated with the first surface 11. The bottom surface of the glue containing and sinking table 22 is a contact surface of the casting insert 3, when the casting insert 3 is demolded, the casting insert 3 is separated from the loudspeaker shell along the direction perpendicular to the first surface 11, and the glue containing and sinking table 22 is used for containing glue pulled by the excessive glue formed when the casting insert 3 is retracted.

The first face 11 is perpendicular to the second face 21, and in order to facilitate demolding of the speaker housing, the speaker housing should have a demolding slope, so that it is also possible that the first face 11 is approximately perpendicular to the second face 21.

The number of the glue-depositing stages 22 may be set as required according to the size of the speaker housing, that is, one or more glue-depositing stages 22 may be provided. For example, in the present embodiment, the speaker housing has two glue-sinking stages 22, and the two glue-sinking stages 22 are disposed away from each other.

The shape of the glue-depositing table 22 may be set according to actual needs, for example, in this embodiment, the glue-depositing table 22 is rectangular, as long as the pouring insert 3 is not affected to separate from the glue-depositing table 22.

Generally, a speaker enclosure includes an upper shell and a lower shell that are connected, both of which are formed by an injection molding process. The speaker housing may be referred to as an upper case or a lower case, and in this embodiment, the upper case is taken as an example, and in other embodiments, the glue depositing table 22 may be disposed on the lower case.

The embodiment also provides a speaker module, the speaker module includes a module housing and a speaker unit disposed in the speaker housing, and the module housing is the speaker housing.

Example two

Referring to fig. 4, a second embodiment of the present utility model is a further improvement made on the basis of the first embodiment, specifically: the glue depositing platform 22 includes a first section 221 and a second section 222 connected to each other, the depth of the second section 222 is greater than that of the first section 221, and one end of the second section 222 away from the first section 221 is communicated with the first surface 11.

This allows the glue depositing station 22 to hold more glue and further prevents the glue from affecting the appearance of the speaker enclosure.

The foregoing description is only of the optional embodiments of the present utility model, and is not intended to limit the scope of the utility model, and all the equivalent structural changes made by the description of the present utility model and the accompanying drawings or the direct/indirect application in other related technical fields are included in the scope of the utility model.
