Description

Technical Field

[0001] This utility model relates to the field of acoustic product technology, specifically to an acoustic product sound port protection structure. Background Technology

[0002] Acoustic products refer to acoustic components such as speakers or microphones. Currently, many electronic devices and equipment, such as mobile phones, headphones, speakers, walkie-talkies, and wearable devices, utilize acoustic products. To ensure normal sound transmission, sound-permeable openings are needed in the casing of these electronic devices or equipment. However, these openings also become direct channels for external dust, moisture, sweat, and even high-pressure water flow to enter, causing internal acoustic products, such as speakers and microphones, to become susceptible to moisture, corrosion, or failure, severely impacting product reliability and lifespan.

[0003] Therefore, it is necessary to develop a sound port protection structure for acoustic products with good protective effect to ensure the reliability of acoustic products and extend their service life. Utility Model Content

[0004] To address the aforementioned shortcomings, the purpose of this utility model is to provide an acoustic product sound port protection structure with a reasonable structural design and good protective effect.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] An acoustic product sound port protection structure includes an acoustic product, a housing, a soft rubber sleeve, and a waterproof cloth. The acoustic product is encased within the housing by the soft rubber sleeve, which has a sound-permeable opening. The waterproof cloth seals the sound-permeable opening. The housing has an opening corresponding to the sound-permeable opening. Several short vertical baffles are spaced apart and arranged side by side on the opening. A tall vertical baffle is positioned between two adjacent short vertical baffles, forming a lower sound channel between the short vertical baffles and the tall vertical baffles. A horizontal baffle is positioned at the top of the tall vertical baffles, and the vertical projection of the horizontal baffle covers the lower sound channel. An upper sound channel is formed between two adjacent horizontal baffles. The upper and lower sound channels are vertically offset. A middle sound channel is formed between the bottom surface of the horizontal baffle and the sidewall of the tall vertical baffle, connecting the upper and lower sound channels.

[0007] In a preferred embodiment of this invention, the upper surface of the horizontal baffle is provided with an upper drainage groove extending along its long side, with both ends of the upper drainage groove extending to the edge of the outer casing. Water flowing into the horizontal baffle is guided along the upper drainage groove to the edge of the outer casing for discharge, preventing accumulation on the surface of the horizontal baffle and reducing the risk of seepage.

[0008] In a preferred embodiment of this invention, the upper surface of the short vertical baffle is provided with a drain groove extending along its long side, with both ends of the drain groove extending to the edge of the outer casing. Water flowing in from the upper sound channel can be discharged along the drain groove after contacting the short vertical baffle, avoiding accumulation and stagnation on the surface of the short vertical baffle and reducing the risk of seepage into the interior.

[0009] As a preferred embodiment of this utility model, the horizontal baffle and the high vertical baffle are provided with drainage holes that penetrate vertically through them, which can drain water located at the opening position.

[0010] As a preferred embodiment of this utility model, the outer wall of the soft rubber sleeve is provided with anti-slip ridges to increase the friction with the inner wall of the outer shell and ensure a tight fit.

[0011] As a preferred embodiment of this utility model, the waterproof cloth is located between the soft rubber sleeve and the acoustic product, resulting in good assembly and eliminating the need for additional bonding processes.

[0012] As a preferred embodiment of this utility model, the thickness of the waterproof cloth is 0.2-0.4mm, which balances waterproof and dustproof performance with acoustic transmission performance, minimizes sound attenuation, and ensures sound propagation effect.

[0013] As a preferred embodiment of this utility model, the outer side of the opening of the outer shell is radially enlarged to form a panel portion, which can serve as the fitting surface of the equipment outer shell, making assembly easier.

[0014] As a preferred embodiment of this utility model, the acoustic product is a loudspeaker or a microphone, which has good versatility. Since loudspeakers and microphones have highly consistent protection requirements, both need to be sound-transparent and waterproof.

[0015] The beneficial effects of this utility model are as follows: The structure of this utility model is reasonably designed. The acoustic product is covered by a soft rubber sleeve, which has a buffering and shock absorption effect and provides initial protection. Utilizing the characteristics of the waterproof cloth, it allows sound to pass through but blocks liquids and particles, providing good waterproof and dustproof effects. At the same time, the structure of the short vertical baffle, the high vertical baffle, and the horizontal baffle are combined to form an upper, middle, and lower sound channel with a staggered labyrinth structure. The tortuous and staggered sound channel path can effectively block rainwater, washing water columns, and larger dust particles that directly intrude, greatly reducing the risk of high-pressure water directly impacting the waterproof cloth. Meanwhile, sound waves can easily propagate in the tortuous sound channel path with minimal sound loss, ensuring acoustic performance.

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0020] See Figures 1 to 3 This embodiment provides an acoustic product sound port protection structure, which includes an acoustic product 1, a shell 2, a soft rubber sleeve 3, and a waterproof fabric 4. The thickness of the waterproof fabric 4 is preferably 0.2–0.4 mm, balancing waterproof and dustproof performance with acoustic transmission performance, minimizing sound attenuation, and ensuring effective sound propagation. The waterproof fabric 4 can be PALL's Versapor 5000RC, which allows sound to pass through but blocks liquids and particles, providing good waterproof and dustproof performance.

[0021] In this embodiment, the acoustic product 1 is described as a microphone. In other embodiments, the acoustic product 1 may also be a speaker.

[0022] The acoustic product 1 is encased in the outer shell 2 by a soft rubber sleeve 3. Preferably, the outer wall of the soft rubber sleeve 3 is provided with anti-slip texture 31, which can increase the friction with the inner wall of the outer shell 2 and make a tight fit.

[0023] The soft rubber sleeve 3 is provided with a sound-permeable opening 32, and the waterproof cloth 4 is closed on the sound-permeable opening 32. Preferably, the waterproof cloth 4 is located between the soft rubber sleeve 3 and the acoustic product 1, which has a good assembly effect and does not require additional bonding process.

[0024] The outer casing 2 has an opening corresponding to the sound transmission port 32. Several short, vertical baffles 21 are spaced apart and arranged side-by-side on the opening. Preferably, a drain groove 211 extending along the long side is provided on the upper surface of each short, vertical baffle 21, with both ends extending to the edge of the outer casing 2. Water flowing in from the upper sound channel can be discharged along the drain groove 211 after contacting the short, vertical baffles 21, avoiding accumulation and stagnation on the surface of the short, vertical baffles 21 and reducing the risk of seepage into the interior.

[0025] A tall vertical baffle 22 is positioned between two adjacent short vertical baffles 21, forming a lower sound channel 23 between the short vertical baffles 21 and the tall vertical baffles 22. A horizontal baffle 24 is provided at the top of the tall vertical baffle 22, and the vertical projection of the horizontal baffle 24 covers the lower sound channel 23. Preferably, an upper drain groove 241 extending along the long side is provided on the upper surface of the horizontal baffle 24, with both ends of the upper drain groove 241 extending to the edge of the outer casing 2. After water comes into contact with the horizontal baffle 24, it can be guided along the upper drain groove 241 to the edge of the outer casing 2 for discharge, avoiding accumulation on the surface of the horizontal baffle 24 and reducing the risk of leakage.

[0026] Preferably, the horizontal baffle 24 and the high vertical baffle 22 are provided with drainage holes 27 that penetrate vertically through them. Water blocked by the waterproof cloth 4 will gather at the opening position, and the water located at the opening position can be discharged through the drainage holes 27.

[0027] An upper channel 25 is formed between two adjacent horizontal baffles 24. The upper channel 25 and the lower channel 23 are offset in the vertical direction. A middle channel 26 is formed between the bottom surface of the horizontal baffle 24 and the side wall of the high vertical baffle 22, so that the upper channel 25 and the lower channel 23 are connected.

[0028] A panel portion 28 is formed by radially increasing the outer side of the end of the housing 2 where an opening is provided. The panel portion 28 can serve as the fitting surface of the housing 2, which is more conducive to assembly.

[0029] In use, the acoustic product 1 is covered by the soft rubber sleeve 3, which has a cushioning and shock absorption effect and provides initial protection. Utilizing the characteristics of the waterproof cloth 4, it allows sound to pass through but blocks liquids and particles, providing good waterproof and dustproof effects. At the same time, the structure of the short vertical baffle 21, the high vertical baffle 22 and the horizontal baffle 24 are combined to form a staggered labyrinthine sound channel. The tortuous and staggered sound channel path can effectively block rainwater, washing water columns and larger dust particles that enter in a straight line, greatly reducing the risk of high-pressure water directly impacting the waterproof cloth 4, while sound waves can easily propagate in the tortuous sound channel path.
