Description

Technical Field

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

[0002] A loudspeaker, also known as a "horn," is a common energy conversion device that converts electrical signals into sound signals. The function of a loudspeaker is to make sound travel farther and louder. When a loudspeaker is working, the sound signal is converted into an electrical signal, which is then amplified by a power amplifier and converted back into a sound signal for playback.

[0003] When some existing horn-shaped loudspeakers play music outdoors, water can seep through the diaphragm into the connection between the dust cover and the frame, potentially causing water to enter the permanent magnet structure. Prolonged exposure to moisture can lead to poor contact in the internal wiring of the loudspeaker, preventing it from functioning properly. Summary of the Invention

[0004] In view of the above-mentioned technical problems in the existing technology, the present invention provides a speaker with a waterproof structure.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A loudspeaker with a waterproof structure is provided, including a housing frame, a permanent magnet base, a diaphragm, a dust cover, and an open-top housing frame. The permanent magnet base is installed on the bottom inner wall of the housing frame. The bottom surface of the diaphragm is fixedly connected to the top of the permanent magnet base. The diaphragm is fixedly connected to the inner wall of the diaphragm. The bottom centers of both the diaphragm and the diaphragm are open. A connecting block is fixedly connected to the inner wall of the bottom surface of the diaphragm. A mounting groove is formed at the center of the surface of the connecting block. The dust cover is located on the inner wall of the mounting groove, and the bottom of its outer surface is in contact with the inner wall of the mounting groove. A circumferentially distributed drainage hole is formed in the middle of the inner wall of the connecting block, and the drainage hole penetrates the outer wall of the diaphragm.

[0007] Preferably, the dust cover is a cone shape with a smaller top and a larger bottom, and the bottom of the outer surface is in contact with the inner wall of the connecting block.

[0008] Preferably, the cross-section of the drain hole is inclined.

[0009] Preferably, a sealing ring is fixedly connected to the bottom of the outer surface of the dust cover, and the top surface of the sealing ring is lower than the opening of the drain hole, and a sealing groove that fits the sealing ring is opened on the inner wall of the connecting block.

[0010] Preferably, a sealing cover is fixedly connected to the top surface of the vibrating diaphragm, and a joint is fixedly connected to the outer wall of the sealing cover, with the bottom surface of the joint tightly fitting the top opening of the box frame.

[0011] Preferably, the surface of the joint is provided with circumferentially distributed water guide holes, and the top surface of the box frame is provided with a flow guide groove extending to the outer wall of the box frame. The flow guide groove is L-shaped and the part extending to the outer wall of the box frame is inclined. The water guide holes are connected to the flow guide groove.

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0022] This embodiment provides a speaker with a waterproof structure, such as... Figures 1 to 5 As shown, the device includes a box frame 1, a permanent magnet base 2, a basin frame 3, a vibrating diaphragm 4, and a dust cover 7. The box frame 1 is open at the top. The permanent magnet base 2 is installed on the bottom inner wall of the box frame 1. The bottom surface of the basin frame 3 is fixedly connected to the top of the permanent magnet base 2. The vibrating diaphragm 4 is fixedly connected to the inner wall of the basin frame 3. The bottom center of both the basin frame 3 and the vibrating diaphragm 4 is open. A connecting block 5 is fixedly connected to the inner wall of the bottom surface of the basin frame 3. An installation groove 6 is opened at the center of the surface of the connecting block 5. The dust cover 7 is located on the inner wall of the installation groove 6, and the bottom of its outer surface is in contact with the inner wall of the installation groove 6. A circumferentially distributed drainage hole 8 is opened in the middle of the inner wall of the connecting block 5, and the drainage hole 8 penetrates the outer wall of the basin frame 3.

[0023] Since the bottom surfaces of both the basin frame 3 and the vibrating diaphragm 4 are open, the connecting block 5 is fixed to the inner wall of the bottom opening of the basin frame 3, and the top of the connecting block 5 extends upward, thus creating a gap between the basin frame 3 and the connecting block 5.

[0024] The bottom of the diaphragm 4 is located in the gap between the frame 3 and the connecting block 5, and the gap between the bottom of the diaphragm 4 and the connecting block 5 is ≥1mm. This prevents the diaphragm 4 from being too close to the dust cover 7, which could affect sound production. When water flows downwards through the diaphragm 4, it will flow out through the drainage hole 8 on the inner wall of the connecting block 5, preventing it from directly affecting the performance of the permanent magnet base 2. It should be noted that the permanent magnet base 2 is part of the magnetic circuit system of the speaker in the prior art, so this technical solution will not be described in detail.

[0025] Furthermore, the dust cover 7 is a cone shape with a smaller top and a larger bottom, and the bottom of its outer surface is fitted to the inner wall of the connecting block 5. There is also a gap of ≥1mm between the top outer surface of the dust cover 7 and the connecting block 5 to prevent the dust cover 7 from being completely pressed against the connecting block 5, which would result in poor sound production of the basket frame 3.

[0026] In addition, the channel cross-section of the drain hole 8 is inclined, with a larger opening at one end near the dust cover 7 and the other end extending outwards from the basin holder 3, which can accurately guide the water flowing into the drain hole 8 outwards.

[0027] In addition, a sealing ring 9 is fixedly connected to the bottom of the outer surface of the dust cover 7, and the top surface of the sealing ring 9 is lower than the opening of the drain hole 8. The inner wall of the connecting block 5 is provided with a sealing groove 10 that fits with the sealing ring 9, so that the dust cover 7 can be installed in a sealed state to prevent dust from passing through the installation groove 6.

[0028] Furthermore, a sealing cover 11 is fixedly connected to the top surface of the diaphragm 4, and a joint 12 is fixedly connected to the outer wall of the sealing cover 11. The bottom surface of the joint 12 fits tightly against the top opening of the frame 1, wherein the bottom surface of the sealing cover 11 completely covers the top surface of the frame 3 and the diaphragm 4, preventing dust or water stains from entering between the frame 3 and the diaphragm 4. In addition, the installation of the joint 12 makes it easy to mount the speaker on the top surface of the frame 1, facilitating subsequent installation.

[0029] The surface of the connector 12 is provided with circumferentially distributed water guide holes 13, and the top surface of the box frame 1 is provided with a flow guide groove 14 extending to the outer wall of the box frame 1. The flow guide groove 14 is L-shaped and the part extending to the outer wall of the box frame 1 is inclined. The water guide holes 13 and the flow guide groove 14 are connected. The water guide holes 13 are provided on the top surface of the connector 12 and the flow guide groove 14 is provided on the surface of the box frame 1, so that the speaker has a multi-faceted water guiding effect.

[0030] In addition, the top surface of the joint 12 is provided with a first threaded hole 16 that is circumferentially distributed and spaced from the water guide hole 13, and the top surface of the box frame 1 is provided with a second threaded hole 17 that communicates with the first threaded hole 16. The inner walls of the first threaded hole 16 and the second threaded hole 17 are connected by a bolt 15. Through the setting of the first threaded hole 16 and the second threaded hole 17, the bolt 15 can pass through the first threaded hole 16 and the second threaded hole 17 to stably connect the box frame 1 and the joint 12, maintaining the overall installation effect.
