Description

Technical Field

[0001] This utility model relates to the field of audio technology, specifically to an audio system with waterproof function. Background Technology

[0002] Sound systems refer to a system of equipment used to amplify and play sound. They are a complete set of equipment that can reproduce and play audio signals. They can make up for the lack of stage space and help create atmosphere in specific environments. Outdoor sound systems can provide a stage anytime and anywhere, providing people with opportunities for performance and entertainment.

[0003] According to a public notice of an outdoor waterproof speaker (publication number: CN218162757U), the aforementioned application uses an outer frame, a roller, a rainproof cloth, a vertical rod, a slider, a base plate, and a support frame to allow the rainproof cloth on the outside of the speaker to be unfolded and retracted. When it rains, unfolding the rainproof cloth can prevent rainwater from entering the speaker's interior.

[0004] However, in actual use, when the rainproof cloth is unfolded, it completely blocks the front of the speaker, which also causes the sound emitted by the speaker to be blocked by the rainproof cloth. This weakens the sound amplitude and affects the sound propagation distance and range. As a result, the speaker cannot be used normally when the rainproof component is opened in rainy weather, affecting the speaker's performance in rainy weather. In view of this, we propose a speaker with waterproof function. Utility Model Content

[0005] The purpose of this invention is to provide a waterproof speaker to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waterproof speaker, comprising a speaker body, a face mask fixedly mounted on the front end of the speaker body, a protective cover fixedly mounted on the outer side of the front end of the speaker body, and a waterproof component disposed inside the protective cover, the waterproof component comprising:

[0027] like Figures 1-6As shown, this utility model provides a technical solution: a waterproof speaker, including a speaker body 1, a faceplate 2 fixedly installed on the front end of the speaker body 1, and a protective cover 3 fixedly installed on the outer side of the front end of the speaker body 1. The protective cover 3 can protect the outer side of the front end of the speaker body 1, and a waterproof component is provided inside the protective cover 3.

[0028] The waterproof component includes: a fixing frame 401, a protective component, a sliding groove 410, and a water leakage channel 411. The fixing frame 401 is fixedly installed on the upper end of the protective cover 3. A motor 402 is fixedly installed on the left end of the fixing frame 401. A rotating roller 403 is fixedly installed through the left side surface of the fixing frame 401 at the right output end of the motor 402. A protective cloth 404 is fixedly installed on the outside of the rotating roller 403. The bottom end of the protective cloth 404 penetrates the upper surface of the protective cover 3. When the motor 402 is started, it can drive the rotating roller 403 to rotate, thereby driving the bottom end of the protective cloth 404 to move vertically in the up and down direction. When the protective cloth 404 moves, it can drive the protective component to move synchronously.

[0029] The protective components include: V-shaped crossbars 405, multiple sets of which are arranged in a vertical array inside the protective cover 3. The left and right surfaces of the V-shaped crossbars 405 are in contact with the inner wall surface of the protective cover 3. A drainage groove 406 is provided at the bottom of the inner surface of each V-shaped crossbar 405. Connecting ropes 407 are fixedly installed at both ends of the bottom surface inside the V-shaped crossbars 405. In the initial state, the bottom end of the protective cloth 404 is located at the upper inner surface of the protective cover 3. The multiple sets of V-shaped crossbars 405 are pulled up using the connecting ropes 407. This keeps the connecting rope 407 taut, leaving a gap between two adjacent V-shaped crossbars 405 to reduce the impact on sound transmission to the speaker body 1. This allows the speaker body 1 to continue to function normally even when the waterproof components are in use. Furthermore, the bottom of the previous V-shaped crossbar 405 and the top surface of the next V-shaped crossbar 405 are on the same horizontal plane. When it rains, rainwater falling into the protective cover 3 will be blocked by multiple sets of V-shaped crossbars 405, preventing rainwater from falling directly onto the mask 2 and entering the speaker body 1, thus affecting its use.

[0030] Rainwater falling onto the front surface of the V-shaped crossbar 405 will slide down the inclined surface of the V-shaped crossbar 405 into the interior of the V-shaped crossbar 405. Rainwater that splashes directly into the interior of the V-shaped crossbar 405 will be absorbed by the water-absorbing sponge 408, preventing it from splashing into the back of the V-shaped crossbar 405 and affecting the use of the speaker body 1. At this time, the rainwater falling into the interior of the V-shaped crossbar 405 will be drained downward through the drainage channel 406. When the speaker is not in use, the motor 402 can be activated to release the protective cloth 404, causing multiple sets of V-shaped crossbars 405 to stack on top of each other. The weight of the V-shaped crossbars 405 will squeeze the water-absorbing sponge 408 below, causing the rainwater inside the water-absorbing sponge 408 to be discharged. The stacked V-shaped crossbars 405 and the protective cloth 404 work together to protect the entire front end of the interior of the protective cover 3, preventing external debris from entering the interior of the protective cover 3 and impacting the mask 2, which could damage the speaker.

[0031] A water-absorbing sponge 408 is fixedly installed on the inner rear wall surface of the V-shaped crossbar 405. Rectangular limiting blocks 409 are fixedly installed at both ends of the V-shaped crossbar 405. The rectangular limiting blocks 409 at both ends of the V-shaped crossbar 405 are slidably connected to the inside of the sliding grooves 410 at both ends of the protective cover 3. There are two sliding grooves 410, which are respectively opened on the left and right end surfaces of the protective cover 3. A water leakage channel 411 is opened on the inner bottom surface of the protective cover 3. The protective component is located directly above the water leakage channel 411. The sliding grooves 410 and the rectangular limiting blocks 409 can guide and limit the movement of the V-shaped crossbar 405, so that the V-shaped crossbar 405 maintains vertical movement in the up and down direction, and avoids displacement when multiple V-shaped crossbars 405 are stacked, which would affect the protective effect.

[0032] A fixed housing 501 is fixedly installed on the upper surface of the protective cover 3. A movable housing 502 is provided at the front end of the fixed housing 501. The fixed frame 401 and the motor 402 are arranged in the gap between the fixed housing 501 and the movable housing 502. The fixed housing 501 and the movable housing 502 are fixedly connected by bolts. When the fixed housing 501 and the movable housing 502 are fixedly closed, the upper ends of the fixed frame 401, the motor 402, the rotating roller 403 and the protective cloth 404 can be protected to prevent rainwater from damaging the motor 402.

[0033] In this invention, when the speaker needs to be used in the rain, the motor 402 can be started to roll up the protective cloth 404. This allows the multiple V-shaped crossbars 405 in the protective assembly to be vertically pulled upwards via the connecting rope 407, with the cooperation of the rectangular limiting block 409 and the sliding groove 410. This waterproofs the front side of the protective cover 3, preventing rainwater from falling onto the mask 2 and entering the speaker body 1, thus preventing damage to the speaker body 1 and affecting its use. Rainwater falling onto the front surface of the V-shaped crossbars 405 and directly entering the V-shaped crossbars 405 will be blocked by the V-shaped crossbars 405 themselves and the water-absorbing sponge 408, and will eventually be drained downwards through the drainage channel 406 and the water leakage channel 411. The gaps between the multiple V-shaped crossbars 405 reduce the obstruction to the sound transmission emitted by the speaker body 1, allowing the speaker to produce sound normally even when the waterproof assembly is in use in the rain.

[0034] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
