The utility model discloses an earphone, referring to fig. 1 to 3, earphone includes shell 100, and the inside of shell 100 is formed with the inner chamber, is equipped with support 200 in the inner chamber, and support 200 is used for installing other component parts such as loudspeaker, mike. The housing 100 is provided with a first sound transmission hole 110, the support 200 is provided with a second sound transmission hole 210, and the first sound transmission hole 110 is opposite to the second sound transmission hole 210.

For the speaker, the first sound transmitting hole 110 and the second sound transmitting hole 210 may be understood as sound emitting holes, and sound emitted from the speaker is emitted to the outside through the second sound transmitting hole 210 and the first sound transmitting hole 110. For a microphone, the first sound transmitting hole 110 and the second sound transmitting hole 210 may be understood as sound receiving holes, and external sound is transmitted into the microphone through the first sound transmitting hole 110 and the second sound transmitting hole 210. Outside dust, water drops and the like are prevented from entering the inner cavity through the first sound transmission hole 110 and the second sound transmission hole 210 to influence the performance of the earphone, and mesh cloth needs to be arranged at the first sound transmission hole 110 and the second sound transmission hole 210.

A microphone or a speaker is installed at an inward side of the second sound transmitting hole 210 to facilitate transmission of sound. A microphone or speaker is mounted on the stand 200. Preferably, the bracket 200 is provided with a mounting groove for mounting a microphone or a loudspeaker, so that the microphone or the loudspeaker can be fixedly mounted, and the connection is more reliable.

The present embodiment takes a microphone as an example to explain the scheme of the present application. The bracket 200 is provided with a mounting groove 220, and the microphone 500 is fixedly arranged in the mounting groove 220. The second sound transmitting hole 210 is aligned with the mounting groove 220 so as to realize sound transmission of the microphone 500.

In this embodiment, the mesh 300 is disposed on a side of the bracket 200 facing the housing 100, and the mesh 300 covers the second sound transmission holes 210. The side of the bracket 200 facing the housing 100 is further provided with a fixing portion 400, and the fixing portion 400 abuts against the edge of the mesh cloth 300. The fixing portion 400 is provided with a third sound transmitting hole 410, and the first sound transmitting hole 110, the second sound transmitting hole 210 and the third sound transmitting hole 410 are opposite to each other, so as to transmit sound.

When assembling, the microphone 500 is firstly arranged in the mounting groove 220; the mesh 300 is then mounted to the outside of the bracket 200; then, the fixing part 400 is installed at the outer side of the support 200, and the fixing part 400 is attached to the edge of the mesh 300 and abuts against the edge of the mesh 300, so that the edge of the mesh 300 is prevented from being tilted, and the mesh 300 is further fixed and limited; finally, the bracket 200 with the mesh 300 and the fixing portion 400 is installed into the housing 100, and in the installation process, the fixing portion 400 can effectively prevent the mesh 300 from being rubbed by other components such as the housing 100 and the like, so that the mesh 300 is prevented from shifting, and the mesh 300 is prevented from deviating. Thereby finally realize the fixed spacing of screen cloth 300, improve the sealing performance of screen cloth 300, realize dustproof, waterproof effect.

Further, the inner side of the housing 100 is pressed against the fixing portion 400, so that the fixing portion 400 is pressed and limited between the housing 100 and the bracket 200, the structure of the fixing portion 400 is more reliable and is not easy to fall off, and the fixing effect on the mesh cloth 300 is improved. Meanwhile, the pressing force of the fixing part 400 to the edge of the mesh 300 can be larger by the squeezing action of the shell 100 and the bracket 200 to the fixing part 400, and the sealing performance is further improved.

Furthermore, the material of the fixing portion 400 is preferably rubber, and the gap between the housing 100 and the bracket 200 is designed to be slightly larger than the thickness of the fixing portion 400, so that after the fixing portion 400 is installed between the housing 100 and the bracket 200, the fixing portion 400 is deformed by compression, and the fixing effect on the mesh cloth 300 is further improved.

A guide structure may be disposed between the support 200 and the casing 100, for example, a guide groove is disposed on the outer side of the support 200, and a guide protrusion is correspondingly disposed on the inner side of the casing 100, so that when the support 200 is installed in the casing 100, the guide protrusion is inserted into the guide groove and slides along the guide groove, thereby facilitating the installation of the support 200, and simultaneously avoiding the support 200 from shifting during the installation process, thereby achieving the direct alignment of the first sound transmission hole 110, the second sound transmission hole 210, and the third sound transmission hole 410.

Further, the fixing portion 400 is provided with a concave portion 420, and the edge of the mesh 300 is located in the concave portion 420, so that when the fixing portion 400 abuts against the edge of the mesh 300, the edge of the mesh 300 is prevented from being exposed, and the mesh 300 is protected to a certain extent. Meanwhile, when the fixing portion 400 is pressed and limited between the bracket 200 and the housing 100, the two sides of the fixing portion 400 are tightly attached to the bracket 200 and the housing 100, which is further beneficial to improving the sealing performance of the mesh cloth 300.

Furthermore, one side of the bracket 200 facing the housing 100 is provided with a connecting column 230, and the fixing portion 400 is fastened to the connecting column 230, so that the fixing connection between the fixing portion 400 and the bracket 200 is realized, the structure is simple, and the assembly is convenient.

The quantity of spliced pole 230 is preferably four, and four spliced poles 230 are located the four angles departments that are close to screen cloth 300, make fixed part 400 assemble to target in place the back can fix spacingly to four angles of screen cloth 300 at first, improve the fixed action to screen cloth 300.

In other embodiments, the fixing portion 400 may be fixedly mounted to the bracket 200 by gluing.

Further, the size of the third sound transmitting hole 410 is larger than the sizes of the first sound transmitting hole 110 and the second sound transmitting hole 210, so as to prevent the third sound transmitting hole 410 from being too small to affect the sound transmission performance.

Further, the mesh 300 is bonded and fixed with the outer side of the bracket 200, which is convenient for assembly.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
