Description

Technical Field

[0001] The present application relates to the technical field of loudspeakers, and in particular to a waterproof loudspeaker. Background Art

[0002] A speaker is a device that converts electrical energy into sound. When different electronic energies are transmitted to the coil, the coil generates an energy that interacts with the magnetic field of the magnet. This interaction causes the paper plate to vibrate. Since the electronic energy changes all the time, the coil will move forward or backward accordingly, so the paper plate of the speaker will move with it. This movement causes the density of the air to change and produce sound.

[0003] There are many types of existing speakers, which are divided into indoor and outdoor types according to the installation occasions. Waterproofing of outdoor speakers is particularly important, especially for speakers installed on the ground, such as in residential areas and campus greening. Most of these speakers are installed facing the sky and are equipped with rain covers on the outside. However, the rain cover can easily affect the sound effect of the speaker, and the speaker itself is not waterproof, which makes the installation complicated. The rain cover needs to be installed at the same time as the speaker, which increases the cost and makes it complicated to replace the speaker. Utility Model Content

[0004] In order to improve the waterproof performance of the speaker, the present application provides a waterproof speaker.

[0005] The waterproof speaker provided in this application adopts the following technical solution:

[0006] A waterproof speaker comprises an upper basin frame, a lower basin frame, drum paper, a spring, a pressure strip and a water retaining strip, wherein the lower basin frame is arranged on the lower side of the upper basin frame, the spring is arranged on the side of the lower basin frame close to the upper basin frame, a through hole is initially provided on the upper basin frame, the upper basin frame is provided with a mounting groove at the opening of the through hole, the drum paper is installed in the mounting groove, the pressure strip is embedded in the mounting groove and abuts against the drum paper, and the water retaining strip is arranged between the pressure strip and the bottom of the mounting groove.

[0007] Through the above technical solution, the gap between the pressure strip and the bottom of the installation groove can be blocked by the water retaining strip, reducing the risk of water inflow, thereby improving the waterproof performance of the speaker.

[0008] Optionally, a plurality of connection rings are provided on one side of the pressure strip close to the bottom of the installation groove, and a plurality of connection grooves for inserting the connection rings are opened on the bottom of the installation groove of the upper basin frame.

[0009] Through the above technical solution, multiple connecting rings and connecting grooves are coordinated to block the water flow, reduce the risk of water inflow, and thus improve the waterproof performance of the speaker.

[0010] Optionally, a guide surface is provided at one end of the connecting ring close to the bottom of the connecting groove.

[0011] Through the above technical solution, by providing the guide surface, the size of the insertion end of the connecting ring is reduced, thereby facilitating the insertion of the connecting ring and the installation of the pressure strip.

[0012] Optionally, absorbent cotton is bonded to the outer side wall of the water retaining strip.

[0013] Through the above technical solution, when water flows in, the absorbent sponge can absorb the water, reducing the risk of water flowing into the speaker and improving the waterproof performance of the speaker.

[0014] Optionally, a fixing block is provided on the side wall of the pressure strip, a vertical groove for inserting the fixing block is opened on the notch of the installation groove, and a horizontal groove for rotatably inserting the fixing block is opened on the wall of the installation groove, and the horizontal groove and the vertical groove are interconnected and perpendicular.

[0015] Through the above technical solution, when the absorbent cotton needs to be replaced, the pressure strip is rotated to rotate the fixed block into the vertical groove, and then the pressure strip is pulled upward. At this time, the water retaining strip can be taken out to replace the absorbent cotton, which facilitates the replacement of the absorbent cotton.

[0016] The beneficial effect of the utility model is that the risk of water flowing into the speaker is reduced through the cooperation of the water retaining strip, the connecting ring and the water absorbing sponge, thereby improving the waterproof performance of the speaker.

DETAILED DESCRIPTION

[0022] The following is combined with Figure 1-4 This application is described in further detail.

[0023] The embodiment of the present application discloses a waterproof speaker.

[0024] Reference Figure 1 , Figure 2 and Figure 3 The waterproof speaker includes an upper basin frame 1, a lower basin frame 2, a drum paper 3, a spring 4, a pressure strip 5 and a water retaining strip 6. The lower basin frame 2 is arranged on the lower side of the upper basin frame 1, and the spring 4 is arranged on the side of the lower basin frame 2 close to the upper basin frame 1. A through hole 11 begins to be provided on the upper basin frame 1. The upper basin frame 1 is provided with a mounting groove 12 at the opening of the through hole 11. The drum paper 3 is installed in the mounting groove 12. The pressure strip 5 is embedded in the mounting groove 12 and abuts against the drum paper 3. The water retaining strip 6 is arranged between the pressure strip 5 and the bottom of the mounting groove 12.

[0025] The gap between the pressure strip 5 and the bottom of the installation groove 12 can be blocked by the water retaining strip 6 to reduce the risk of water inflow, thereby improving the waterproof performance of the speaker.

[0026] Reference Figure 3 A plurality of connecting rings 51 are arranged on one side of the pressure strip 5 close to the bottom of the installation groove 12 , and a plurality of connecting grooves 121 for inserting the connecting rings 51 are opened at the bottom of the installation groove 12 on the upper basin frame 1 .

[0027] By cooperating with a plurality of connection rings 51 and connection grooves 121, water flow is blocked, reducing the risk of water inflow, thereby improving the waterproof performance of the speaker.
