Description

Technical Field

[0001] This utility model relates to the field of constant impedance speaker technology, and in particular to a constant impedance speaker with good vibration damping effect. Background Technology

[0002] A constant impedance speaker is an audio device designed for use with constant impedance amplifiers. Compared to other types of speakers (such as constant voltage or variable impedance speakers), constant impedance speakers are characterized by providing a relatively stable impedance value throughout the entire frequency range, typically 4Ω, 8Ω, or 16Ω. Constant impedance speakers offer good compatibility, working with most audio amplifiers, especially those designed to drive specific impedances. Due to their impedance stability, they provide consistent sound quality, unaffected by frequency variations. The parameters of constant impedance speakers are relatively simple to design and tune, making their design and manufacturing relatively easy. When selecting speakers, understanding their impedance characteristics and matching them with the amplifier is crucial to ensuring optimal sound quality and performance.

[0003] Some existing constant impedance speakers are mounted on one side of the wall using brackets to achieve better playback. However, when the speaker is producing sound, the internal air pressure changes, which can cause the speaker casing and brackets to vibrate, thus affecting the sound quality. Therefore, this problem needs to be solved. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a constant impedance speaker with good shock absorption.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A constant impedance speaker with good vibration damping includes a U-shaped plate. Two hanging plates are fixedly connected to one side of the U-shaped plate. Each of the two hanging plates has a support mechanism for supporting the U-shaped plate. A speaker is installed inside the side of the U-shaped plate away from the hanging plates. Locking holes are opened at both ends of the speaker. A first locking cap and a second locking cap are slidably connected inside the two locking holes, respectively. The surface of the second locking cap away from the speaker has a moving mechanism for moving the second locking cap. A first damper is fixedly connected to the surface of the first locking cap away from the speaker. The other end of the first damper is fixedly connected to the inner surface of the U-shaped plate. A first damping spring is sleeved on the surface of the first damper. The top end of the first damping spring is fixedly connected to the bottom of the first locking cap, and the bottom end of the first damping spring is fixedly connected to the inner surface of the U-shaped plate. By setting up the damper, the vibration generated by the speaker can be absorbed and buffered.

[0007] As a further embodiment of this utility model, the support mechanism includes a base plate, which is disposed on one side of the U-shaped plate. A sliding groove is provided on the side of the base plate near the hanging plate, and a hanging groove is provided at the bottom of the sliding groove. The hanging plate is slidably connected to the sliding groove and the hanging groove. An installation hole is provided on one side of the base plate. The speaker can be supported by the base plate.

[0008] As a further embodiment of this utility model, the moving mechanism includes a first synchronous wheel, which is rotatably connected to the top of the U-shaped plate. A lead screw is sleeved on the top of the first synchronous wheel. A connecting plate is fixedly connected to the end of the lead screw near the second lock cap. A second damper is fixedly connected to the end of the connecting plate near the second lock cap. The other end of the second damper is fixedly connected to the top of the second lock cap. A second damping spring is sleeved on the surface of the second damper. The top end of the second damping spring is fixedly connected to the bottom of the connecting plate, and the bottom end of the second damping spring is fixedly connected to the top of the second lock cap. Two constraint members are symmetrically fixedly connected to the top of the second damper. Both constraint members are slidably connected to the top of the U-shaped plate. A rotating mechanism for rotating the first synchronous wheel is provided on the surface of the first synchronous wheel. The second lock cap can be moved by the lead screw.

[0009] As a further embodiment of this utility model, the rotating mechanism includes a rotating shaft, which is rotatably connected to the top of the U-shaped plate. A second synchronous wheel is sleeved on the surface of the rotating shaft near the first synchronous wheel. The surfaces of the first and second synchronous wheels are sleeved with the same synchronous belt. A gear is sleeved on the surface of the rotating shaft away from the synchronous belt. A rack is fitted on the surface of the gear. The rack is fixedly connected to one side of the slide groove and hanging groove. The second synchronous wheel can be rotated by the synchronous belt.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. This utility model employs a damper-based support for the speaker, effectively absorbing and buffering the vibrations generated by the speaker. This solves the problem of changes in internal air pressure during speaker output, which can cause vibrations in the speaker casing and mounting hardware, thus affecting sound quality. The speaker's back is angled, and when placed between the first and second locking caps, the speaker compresses the caps, causing them to contract. This contraction secures the speaker. Because the speaker is connected to the U-shaped plate via the damper, the damper absorbs and buffers vibrations, preventing them from being transmitted to the U-shaped plate and causing noise.

[0023] Reference Figure 3 and Figure 5 In a preferred embodiment, the moving mechanism includes a first synchronous wheel 2, which is rotatably connected to the top of the U-shaped plate 1. A lead screw 205 is sleeved on the top of the first synchronous wheel 2. A connecting plate 207 is fixedly connected to the end of the lead screw 205 near the second lock cap 210. A second damper 208 is fixedly connected to the end of the connecting plate 207 near the second lock cap 210. The other end of the second damper 208 is fixedly connected to the top of the second lock cap 210. A second damping spring 209 is sleeved on the surface of the second damper 208. The top end of the second damping spring 209 is fixedly connected to the bottom of the connecting plate 207, and the bottom end of the second damping spring 209 is fixedly connected to the top of the second lock cap 210.

[0024] Reference Figure 3 and Figure 5In a preferred embodiment, the rotating mechanism includes a rotating shaft 203, which is rotatably connected to the top of the U-shaped plate 1. A second synchronous wheel 202 is sleeved on the surface of the rotating shaft 203 near the first synchronous wheel 2.

[0025] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: In use, the base plate 3 is first installed in a suitable position through the mounting hole 304, and then the speaker 4 is installed on one side of the U-shaped plate 1. A first locking cap 104 and a second locking cap 210 are respectively installed on one side of the U-shaped plate 1, and the first locking cap 104 and the second locking cap 210 are connected to the U-shaped plate 1 through a first damper 102 and a second damper 208. The back of the speaker 4 is inclined. When the speaker 4 is placed between the first locking cap 104 and the second locking cap 210, the speaker 4 will... The first locking cap 104 and the second locking cap 210 are pressed together, causing them to contract. This contraction allows the speaker 4 to be securely fixed. Since the speaker 4 is connected to the U-shaped plate 1 via a damper, the damper absorbs and buffers vibrations when the speaker 4 vibrates, preventing the vibrations from being transmitted to the U-shaped plate 1 and causing noise. A hanging plate 101 is installed on one side of the U-shaped plate 1, and the hanging plate 101 cooperates with the sliding groove 301 and hanging slot 302 on one side of the base plate 3. After the speaker 4 is installed, the hanging plate 101 is inserted into the sliding groove 301. After the U-shaped plate 1 is fully inserted into the slide 301, it will drive the hanging plate 101 to move downwards so that it can enter the hanging slot 302. After the hanging plate 101 enters the hanging slot 302, with the cooperation of the weight of the speaker 4, the installation of the U-shaped plate 1 can be completed. A rack 303 is installed in one of the slides 301 and the hanging slot 302, and the rack 303 is engaged with the gear 204 on one side of the U-shaped plate 1. So when the U-shaped plate 1 moves horizontally, the gear 204 will also rotate. A timing belt 201 is installed on the top of the gear 204, and the timing belt 201 is connected to the first... The first synchronous wheel 2 on the top of the second lock cap 210 is engaged with the second lock cap 210. When the gear 204 rotates, driven by the synchronous belt 201, the first synchronous wheel 2 will also rotate synchronously. A lead screw 205 is sleeved on the top of the first synchronous wheel 2 and is installed on one side of the second lock cap 210. Because there are constraint members 206 installed on both sides of the lead screw 205, the lead screw 205 is fixed and cannot rotate. When the first synchronous wheel 2 rotates, the lead screw 205 can be moved down, so that the second lock cap 210 can be inserted into the lock hole 401, thus completing the final installation of the speaker 4.
