Description

Technical Field

[0001] The present application relates to the technical field of loudspeakers, and in particular to a bass loudspeaker. Background Art

[0002] A horn, also known as a loudspeaker, is essentially a transducer device that can convert electrical energy into sound and is widely used in people's daily lives. The principle of sound generation is that a magnet generates a permanent magnetic field. When the coil is energized, an AC signal is input into the coil. According to the left-hand rule, the energized coil moves in the permanent magnetic field due to the magnetic force. The coil drives the sound membrane to vibrate, causing the density of the air to change and produce sound.

[0003] With respect to the above-mentioned related technologies, the inventor believes that the speaker is generally fixed and installed by bolts, and the speaker needs to be repaired after being used for a long time. The repair requires the speaker to be disassembled and assembled by bolts, which is inconvenient. Utility Model Content

[0004] In order to facilitate the maintenance of the speaker, the present application provides a bass speaker.

[0005] The present application provides a woofer that adopts the following technical solution:

[0006] A bass speaker comprises a speaker body, a mesh cover and a fixing part, wherein the speaker body is provided with a mounting groove for inserting the mesh cover, the fixing part comprises a fixing block and a first compression spring, the speaker body is provided with a sliding groove on the wall of the mounting groove, the fixing block is slidably connected in the sliding groove, the first compression spring is arranged between the bottom of the sliding groove and the fixing block, the side wall of the mesh cover is provided with a fixing groove for inserting the fixing block, a guide surface is arranged at one end of the fixing block away from the first compression spring, and the guide surface is inclined toward the insertion direction of the mesh cover.

[0007] Through the above technical solution, when the speaker needs to be inspected, the mesh cover can be pressed down. Since the sliding groove limits the fixed block, the fixed block can only slide into the sliding groove. Then the mesh cover is rotated to make the fixed groove and the sliding groove misaligned. Then the mesh cover is taken out and the inside of the speaker can be inspected, which facilitates the inspection of the speaker.

[0008] Optionally, the speaker body is provided with a connecting ring on the wall of the mounting groove, and a second compression spring is provided between the connecting ring and the mesh cover.

[0009] Through the above technical solution, the second compression spring presses the mesh cover upward, reducing the risk of the mesh cover sliding downward, thereby causing the mesh cover to fall out, and making the fixation of the mesh cover more stable.

[0010] The beneficial effect of the utility model is that when the speaker needs to be repaired, the mesh cover can be pressed downwards. Since the sliding groove limits the fixed block, the fixed block can only slide into the sliding groove. Then the mesh cover is rotated to misalign the fixed groove and the sliding groove. Then the mesh cover is taken out and the inside of the speaker can be repaired, which facilitates the repair of the speaker. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The following is combined with Figure 1-3 This application is described in further detail.

[0016] The embodiment of the present application discloses a bass speaker.

[0017] Reference Figure 1 , Figure 2 and Figure 3 The bass speaker includes a speaker body 1, a mesh cover 2 and a fixing member 3. The speaker body 1 is provided with a mounting groove 11 for inserting the mesh cover 2. The fixing member 3 includes a fixing block 31 and a first compression spring 32. The speaker body 1 is provided with a sliding groove 111 on the groove wall of the mounting groove 11. The fixing block 31 is slidably connected in the sliding groove 111. The first compression spring 32 is arranged between the bottom of the sliding groove 111 and the fixing block 31. The side wall of the mesh cover 2 is provided with a fixing groove 21 for inserting the fixing block 31. A guide surface 311 is arranged at one end of the fixing block 31 away from the first compression spring 32, and the guide surface 311 is inclined toward the insertion direction of the mesh cover 2.

[0018] When the speaker needs to be inspected, the mesh cover 2 can be pressed downward. Since the sliding groove 111 limits the fixed block 31, the fixed block 31 can only slide into the sliding groove 111. Then the mesh cover 2 is rotated to make the fixed groove 21 and the sliding groove 111 misaligned. Then the mesh cover 2 is taken out and the inside of the speaker can be inspected, which facilitates the inspection of the speaker.

[0019] Reference Figure 3The speaker body 1 is provided with a connecting ring 112 on the wall of the mounting groove 11 , and a second compression spring 4 is provided between the connecting ring 112 and the mesh cover 2 .

[0020] The second compression spring 4 presses the mesh cover 2 upwards, reducing the risk of the mesh cover 2 sliding downwards and thus causing the mesh cover 2 to fall out, thereby making the fixation of the mesh cover 2 more stable.

[0021] The implementation principle of a bass speaker in an embodiment of the present application is as follows: when the speaker needs to be repaired, the mesh cover 2 can be pressed downward, and since the sliding groove 111 limits the fixed block 31, the fixed block 31 can only slide into the sliding groove 111, and then the mesh cover 2 is rotated to misalign the fixed groove 21 and the sliding groove 111, and then the mesh cover 2 is taken out, and the inside of the speaker can be repaired, which facilitates the repair of the speaker.

[0022] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
