Description

Technical Field

[0001] The utility model relates to the technical field of electroacoustic converters, in particular to a loudspeaker module. Background Art

[0002] The speaker module includes a module shell and a speaker unit arranged in the module shell. The module shell has a placement cavity and a rear cavity that are connected. In order to reduce the thickness of the speaker module and other factors, the placement cavity of some speaker modules adopts an open design and forms a window on the surface of the module shell. The gap between the edge of the speaker unit and the window is sealed with sealant. Please refer to the Chinese utility model patent with application number 202222367621.6.

[0003] However, the production yield of the speaker module with the above structure is not very high. The reason is that when applying sealant, a small amount of sealant will flow into the placement cavity along the gap between the speaker unit and the window, and block the air vent hole of the speaker unit used to connect to the rear cavity, causing the speaker unit to vent air smoothly. Utility Model Content

[0004] The technical problem solved by the utility model is to provide a loudspeaker module with high production yield.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: a speaker module, comprising:

[0008] An isolating member, wherein one side surface of the isolating member has an adhesive layer, the isolating member is connected to the module housing and the speaker unit through the adhesive layer, and the isolating member covers the gap between the inner side wall of the window and the speaker unit.

[0009] In one embodiment, the isolation element is a plastic film.

[0010] In one embodiment, the isolation member is planar in shape as a whole.

[0011] In one embodiment, the module housing has an adhesive groove arranged around the window, the adhesive groove is connected to the inner wall of the window, and the bottom surface of the adhesive groove is a first adhesive plane that cooperates with the adhesive layer.

[0012] In one embodiment, the isolating member is in the shape of a ring frame as a whole.

[0013] In one embodiment, it further includes a sealing colloid connecting the separator, the speaker unit and the module housing.

[0030] Embodiment 1

[0031] Please refer to Figure 1 and Figure 2, Embodiment 1 of the present utility model is: A speaker module, including a module housing 1, a speaker unit 2, and a spacer 3. The module housing 1 has a placement cavity 11 and a rear cavity 12 that are connected and communicated. The placement cavity 11 communicates with the outer surface of the module housing 1 to form a window 13; the speaker unit 2 is placed in the placement cavity 11, and the speaker unit 2 includes a magnetic circuit assembly. The magnetic circuit assembly includes a yoke 22, and the yoke 22 is exposed from the window 13; one side surface of the spacer 3 has an adhesive layer, and the spacer 3 connects the module housing 1 and the speaker unit 2 through the adhesive layer. The spacer 3 covers the gap between the inner wall of the window 13 and the speaker unit 2.

[0032] In this embodiment, the spacer 3 is a plastic film, such as a PET film, etc. It is not difficult to understand that the spacer 3 seals the gap between the inner wall of the window 13 and the speaker unit 2.

[0033] To facilitate the bonding and fixing of the spacer 3 to the module housing 1, the module housing 1 has an adhesive groove provided around the window 13. The adhesive groove communicates with the inner wall of the window 13, and the bottom surface of the adhesive groove is a first bonding plane 14 that cooperates with the adhesive layer.

[0034] In some embodiments, the spacer 3 is integrally planar. At this time, the spacer 3 covers the entire exposed surface area of the yoke 22. However, to reduce the manufacturing consumables of the spacer 3, in this embodiment, the spacer 3 is integrally in a ring frame shape.

[0035] To improve the connection reliability between the spacer 3, the speaker unit 2, and the module housing 1, optionally, the speaker module further includes a sealing colloid (not shown in the figure) that connects the spacer 3, the speaker unit 2, and the module housing 1. This can improve the anti-drop ability of the speaker module. In an actual product, the number of the sealing colloids can be two. One sealing colloid connects the spacer 3 and the module housing 1, and the other sealing colloid connects the spacer 3 and the speaker unit 2. Of course, it is also possible that the number of the sealing colloids is one. At this time, the sealing colloid connects the spacer 3, the speaker unit 2, and the module housing 1 simultaneously. Preferably, the sealing colloid is in a ring frame shape.

[0036] In other embodiments, the spacer 3 can also be a mesh cloth. At this time, the sealing colloid covers the entire exposed surface area of the mesh cloth. The mesh cloth can reduce the fluidity of the sealing colloid and capture the sealing colloid, and can also prevent the sealing colloid from flowing into the placement cavity 11 and blocking the air vents 21 of the speaker unit 2.

[0037] The edge of the yoke 22 is provided with a pressing groove, and the bottom surface of the pressing groove is a second bonding plane 221 that cooperates with the back adhesive layer. In this way, it is convenient to bond the annular spacer 3 to the speaker unit 2. Preferably, the second bonding plane 221 is flush with the first bonding plane 14.

[0038] The above are only optional embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the inventive concept of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
