Description

Technical Field

[0001] This utility model relates to the field of loudspeaker technology, specifically to a loudspeaker with waterproof measures. Background Technology

[0002] A loudspeaker is a transducer that converts electrical signals into sound signals. Based on their working principle, loudspeakers can be classified into electromagnetic, electrodynamic, piezoelectric, and electrostatic types. During the use of loudspeakers, in order to cope with harsh environments such as humidity and rain, staff will waterproof the loudspeakers. Waterproofing not only prevents water from entering and causing damage or performance degradation to the loudspeaker components, but also improves the durability of the loudspeakers in humid environments, providing users with more convenience and protection.

[0003] Existing loudspeakers typically use a waterproof membrane to prevent liquid intrusion and maintain sound transmission performance. However, relying solely on this single waterproof membrane for protection is relatively limited in effectiveness. It cannot effectively guide and quickly drain moisture from inside the loudspeaker, and prolonged moisture retention can negatively impact the loudspeaker's lifespan, hindering its normal operation.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-6 As shown, a waterproof speaker includes a mounting housing 1. A top cover 4, adapted to the top opening of the mounting housing 1, and a speaker assembly 2 for sound propagation, located at the bottom of the inner cavity of the mounting housing 1. By setting the speaker assembly 2, audio signals can be amplified and sound reproduced, thus meeting the needs of communication, entertainment, and information dissemination. It should be noted that in actual use, the speaker assembly 2 is positioned and installed within the space formed by the mounting housing 1 and the top cover 4. The mounting housing 1 and the top cover 4 will replace the speaker assembly 2 in contact with the external environment and provide moisture protection. A partition 5... The mounting housing 1 is fixed inside the top cover 4. The partition 5 has intermittently spaced sound outlet holes 6. The mounting housing 1 is connected to the outside through the sound outlet holes 6. The U-shaped bracket 11 is set at the bottom of the mounting housing 1. The top of the inner cavity of the mounting housing 1 is provided with a waterproof component 7 to prevent moisture from entering and affecting the speaker assembly 2. By setting the waterproof component 7, on the one hand, moisture can be prevented from entering with minimal impact on the sound of the speaker assembly 2. On the other hand, the intruded moisture can be guided to accumulate and be quickly discharged into the external environment of the mounting housing 1, thus avoiding the long-term retention of moisture and its impact on the speaker assembly 2.

[0017] The speaker assembly 2 includes a mounting groove 21 located at the bottom of the inner cavity of the mounting housing 1, and a speaker body 22 is installed inside the mounting groove 21. Figure 4 , Figure 5As shown, the speaker body 22 inside the mounting slot 21 can amplify the audio signal and reproduce the sound, thereby meeting the needs of communication, entertainment and information dissemination. It should be noted that the speaker body 22 in this utility model is consistent with the existing speaker structure and technical effects. This utility model does not make any changes to the circuit, structure, etc. of the existing speaker body 22.

[0018] Sealant 3 is provided on the inner wall of the mounting groove 21. The sealant 3 is connected to both the speaker body 22 and the inner wall of the mounting groove 21. Figure 4 , Figure 5 As shown, by setting the sealant 3, on the one hand, the installation stability of the speaker body 22 inside the mounting groove 21 can be enhanced, and on the other hand, it is beneficial to improve the sealing performance between the speaker body 22 and the inner wall of the mounting groove 21, preventing further intrusion of moisture.

[0019] The waterproof component 7 includes a support plate 71 fixed to the top of the inner cavity of the mounting housing 1. The top of the support plate 71 has multiple symmetrically arranged protrusions 72. Each protrusion 72 has a strip-shaped through groove 73 inside, and a flared waterproof membrane 74 is fixedly connected inside the strip-shaped through groove 73. Water guide channels 75 are provided between adjacent protrusions 72 for guiding moisture. Figure 4 , Figure 5 and Figure 6 As shown, when external moisture enters the housing 1 through the sound outlet 6, the moisture is first blocked by the speaker waterproof membrane 74 inside each strip groove 73. Then, under the influence of gravity, the moisture flows along the inclined surfaces on both sides of the protruding ridge 72 and accumulates at the bottom of the inner cavity of the water guide groove 75. It should be noted that the speaker waterproof membrane 74 is a high-polymer acoustic material made of EPTFE or TPU film. It adopts a microporous structure design and has waterproof, dustproof, breathable and sound-transmitting functions, with a protection level of up to IP68. Therefore, the speaker waterproof membrane 74 can prevent moisture from entering while minimizing the impact on the sound of the speaker assembly 2.

[0020] The top outer side of the mounting shell 1 is provided with a liquid storage chamber 9. A water inlet groove 8 corresponding to the water guide groove 75 is provided on the top side of one side of the liquid storage chamber 9. Drainage grooves 10 are provided intermittently at equal intervals on the bottom side of one side of the liquid storage chamber 9. Figure 4 , Figure 5 and Figure 6 As shown, the water collected at the bottom of the inner cavity of the water channel 75 will be discharged into the interior of the mounting shell 1 through the water inlet 8, the liquid storage chamber 9 and the drainage channel 10 in sequence. This can prevent water from staying for a long time and affecting the speaker assembly 2. Compared with the common method of relying on the single structure of the speaker waterproof membrane 74 for protection, the drainage and waterproof effects are better.

[0021] The bottom of the U-shaped bracket 11 is provided with a positioning groove 14. Both ends of the U-shaped bracket 11 are rotatably connected to rotating shafts 12. One end of the rotating shaft 12 passes through the U-shaped bracket 11 and connects to the mounting housing 1. The other end of the rotating shaft 12 has a locking nut 13 on its outer side for easy adjustment of the angle of the mounting housing 1. Figure 1 , Figure 2 and Figure 3 As shown, the positioning groove 14, together with bolts and other fasteners, can be used to fix and install this utility model. When it is necessary to adjust the sound-emitting angle of the mounting shell 1, the mounting shell 1 can be swung to the required angle first, and then the locking nut 13 can be tightened to restrict the swing of the mounting shell 1. This makes it easier for the staff to adjust the sound-emitting angle according to the actual needs, thus improving the practicality.

[0022] The bottom edge of the encapsulation top cover 4 is provided with a first mating part 15, and the top edge of the mounting shell 1 is provided with a second mating part 16. Multiple limiting bolts 17 are symmetrically arranged inside the first mating part 15. The bottom end of each limiting bolt 17 extends through to the outside of the second mating part 16 and is screwed with a fastening nut 18. Figure 2 , Figure 3 and Figure 4 As shown, by setting the limit bolt 17 and the fastening nut 18, the mounting shell 1 and the encapsulation top cover 4 can be easily disassembled and assembled, thereby facilitating the maintenance and cleaning of the internal components of the mounting shell 1 by the staff.

[0023] Working principle: First, the staff can use the positioning groove 14 and fasteners such as bolts to fix and install this utility model. Then, the speaker component 2 amplifies the audio signal and reproduces the sound to meet the needs of communication, entertainment and information dissemination. When the mounting shell 1 is in a humid environment such as rain, the waterproof component 7 can prevent water intrusion with minimal impact on the sound of the speaker component 2. At the same time, it can also guide the intruded water, so as to promote the water to accumulate and be quickly discharged to the external environment of the mounting shell 1. This avoids water from staying for a long time and affecting the speaker component 2. Compared with the common method of relying on the single structure of the speaker waterproof membrane 74 for protection, the drainage and waterproof effects are better.
