The present invention also discloses an earphone.

Description

A waterproof speaker and earphone

technical field

The invention relates to a speaker and an earphone, in particular to a waterproof speaker and an earphone.

Background technique

Existing horn structures are shown in Figures 1 to 3, which are the front view, right view and top view of the horn respectively, wherein the horn is cylindrical, and the horn vibration coil lead-out line 11 extends from the outside of the horn to the front end of the horn, and passes through The welding spot 12 of the horn is fixed on the front end. In order to protect the lead-out wire 11 of the horn vibrating coil, a protective glue 13 is provided outside the lead-out wire 11 of the horn vibrating coil. The speaker is assembled with the earphone cavity 21 to form an earphone. As shown in FIG. But the waterproof performance of the above-mentioned assembled earphone is poor. According to the analysis of the inventor, the reasons for the poor waterproof performance are as follows. Since the side of the speaker cannot be seamlessly fitted with the inner wall of the earphone cavity 21, water will flow from the side of the speaker and the inner wall of the earphone cavity. The gap between the inner walls of the earphone cavity 21 infiltrates; secondly, since the front end of the speaker has no waterproof structure, water can also infiltrate into the inside of the speaker from the front end of the speaker.

Contents of the invention

In view of this, the purpose of the embodiments of the present invention is to provide a waterproof speaker, aiming to solve the problem of poor waterproof performance of earphones in the prior art.

The invention provides a waterproof horn. The lead-out line of the horn vibration coil of the waterproof horn extends from the interior of the waterproof horn to the front end of the waterproof horn, and is fixed to the front end via horn solder joints. The side of the waterproof horn is covered with an elastic waterproof ring.

Preferably, the elastic waterproof ring is rubber.

Preferably, the front end of the waterproof horn is pasted with a waterproof mesh.

Preferably, the side of the waterproof horn is provided with an annular groove for accommodating the waterproof ring.

Preferably, the waterproof speaker includes a protective cover and a voice coil arranged inside the protective cover, the inner surface of the protective cover is provided with a lead groove penetrating from the bottom of the waterproof speaker to the front end, and the speaker led from the voice coil The lead-out line of the vibration coil extends to the front end of the waterproof horn through the lead-in groove.

Preferably, a diaphragm, a voice coil, a washer, a magnet, a T-iron, a tuning cloth and a circuit board are sequentially arranged inside the protective cover from the front end to the bottom of the waterproof horn, and the voice coil runs through the diaphragm, The washer and the magnet, the lead-out line of the speaker vibration coil are led out through the T-iron and extended to the front end of the waterproof speaker, and the tuning cloth and the circuit board are arranged at the bottom of the T-iron.

The protective cover is in the shape of a ring, and a sealant is coated on the junction between the inner side and other parts.

Preferably, the waterproof horn is a 6.9mm waterproof horn.

The present invention also provides an earphone, comprising an earphone cavity and a waterproof speaker accommodated inside the earphone cavity, the waterproof speaker being the aforementioned waterproof speaker.

In the embodiment of the present invention, since the lead-out wires of the horn vibration coil go inside the waterproof horn, there is no need to add protective glue on the outside as in the prior art, which saves costs; and because the side of the waterproof horn is covered with an elastic waterproof ring, When the speaker and the earphone cavity are assembled, the elastic waterproof ring makes the waterproof speaker and the inner wall of the earphone cavity fit seamlessly, so that water cannot penetrate from here; at the same time, the elastic waterproof ring can fully ensure the firmness of the assembly, and also make the speaker assembly Stablize.

detailed description

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

The present invention provides a waterproof speaker with good waterproof performance, as shown in Figure 5 to Figure 8, the same as in the prior art is that the waterproof speaker is cylindrical, but the speaker vibration coil lead-out line 31 of the waterproof speaker is self-waterproof The inside of the horn extends to the front end of the waterproof horn, and is fixed to the front end via the horn welding spot 32, and the side of the waterproof horn is covered with an elastic waterproof ring.

Because the speaker vibrating coil lead-out line 31 goes inside the waterproof speaker, it is not necessary to add protective glue 13 outside like the prior art, which saves costs; When the speaker and the earphone cavity 21 are assembled, the elastic waterproof ring makes the waterproof speaker and the inner wall of the earphone cavity 21 fit seamlessly, so that water cannot penetrate from here; The waterproof speaker assembly is stable.

Preferably, the elastic waterproof ring can be made of rubber, and of course other elastic materials can also be used.
