[0002] The loudspeaker is commonly known as a "horn". It is a very commonly used electroacoustic transducer device that can be found in all electronic and electrical equipment that make sound. Its main structure is composed of a sound unit, a mounting frame and a front cover. The loudspeaker is a transducer device that converts electrical signals into sound signals. The performance of the loudspeaker has a great influence on the sound quality. The loudspeaker is the weakest component in the audio equipment, but it is also the most important component for the sound effect. There are many types of loudspeakers, and the prices vary greatly. Audio electrical energy vibrates the cone or diaphragm through electromagnetic, piezoelectric or electrostatic effects, and resonates (resonates) with the surrounding air to produce sound;

[0003] For example, the prior art application number CN201821321163.X discloses a low-temperature-resistant speaker with a rubber-edged sound cone, which includes a speaker and a sound cone body. The sound cone body is provided on the top of the speaker, and one side of the sound cone body is connected to a basin frame by mounting screws. The inner top surface of the sound cone body is provided with an internal thread, and a pleated layer is provided on the inner surface of the sound cone body below the internal thread. A paper layer is provided on one side of the pleated layer on the outer surface of the sound cone body.

[0004] The above-mentioned prior art has been found through actual use to transmit sound mainly through the hollow openings in the protective cover. However, such hollow openings easily collect a lot of dust and do not have a waterproof effect, which will seriously affect the service life of the speaker. For this reason, we have improved the above-mentioned solution based on actual usage. Utility Model Content

[0005] In order to solve the problem that the above-mentioned hollow openings easily collect a lot of dust and have no waterproof effect, which will seriously affect the service life of the speaker, the utility model aims to provide a speaker front cover and a speaker.

[0007] Preferably, ear blocks are integrally provided on both sides of the mounting frame and a No. 1 bolt hole is provided in each ear block, a No. 2 bolt hole is provided in the rear side of the mounting frame, and the front side of the speaker body is used to fix the speaker body through bolts and threaded arrangements of the No. 2 bolt holes.

[0008] Preferably, an annular groove is provided on the front side of the mounting frame, and a cushion is provided between the mounting frame and the front cover to increase the vibration force of the front cover.

[0009] Preferably, the cushion member includes a corrugated pad and a magnetic block, and a magnetic block is provided on the rear side of the corrugated pad for fixing the front cover and the mounting frame.

[0010] Preferably, the front side of the corrugated pad is fixed to the rear side of the front cover by glue, and the rear side of the corrugated pad is fixed with a sealing ring by glue. The inner wall of the sealing ring is fixed to the outer surface of the magnetic block by glue, and the sealing ring can increase the waterproofness of the speaker body.

[0011] Preferably, the magnetic block is annular, and when the rear side of the magnetic block is attracted to the annular groove and the rear side of the sealing ring is pressed against the front side of the mounting bracket, water is prevented from entering the speaker body;

[0012] 1. The utility model provides a plurality of grooves in the front cover, and the inner wall of each groove is designed in a sloped manner, which can prevent dust accumulation from directly flowing back into the through-hole and entering the surface of the speaker body, and has a certain dust-proof effect. When the device is used outdoors, when the front cover is hit by rain, the water flow will not directly enter the through-hole and cause water to enter the speaker body because of the slope of the slope and the fact that the through-hole and the opening of the groove are not directly opposite. The water flow will achieve the effect of dustproofing and waterproofing at the same time.

[0013] 2. A cushion is installed between the front cover and the mounting frame. When the device is in use, the sound generated will cause the device to generate a certain vibration force. The vibration force will pass through the corrugated pad in the cushion and cause the corrugated pad to drive the front cover to vibrate slightly, causing the dust in the groove in the front cover to slide down, thus achieving an automatic dust cleaning effect.
