Description

Technical Field

[0001] This utility model belongs to the field of loudspeaker technology, and in particular relates to a vibration damping structure for a loudspeaker. Background Technology

[0002] A loudspeaker consists of a fixed permanent magnet, a coil, and a conical paper cone. It can be electrodynamic or electromagnetic, and is classified as an internal or external loudspeaker. When a loudspeaker is working, an alternating current, the magnitude and direction of which change over time, flows through the coil to reproduce signals such as music and speech. However, because sound generates vibrations, the loudspeaker itself vibrates more strongly as the sound level increases. This strong vibration can damage the loudspeaker. To reduce damage, a vibration-damping structure is needed within the loudspeaker itself. A search revealed that patent application number 202322112450.7 discloses a vibration damping structure for a loudspeaker, including a loudspeaker body. A round rod is fixedly connected to the supporting end of the loudspeaker body. Multiple connecting blocks are fixedly connected to the annular surface of the round rod. A circular groove is formed on the side of the connecting blocks away from the loudspeaker body. A buffer is inserted into the circular groove. An H-shaped frame is fixedly connected to the end of the buffer away from the connecting block. The H-shaped frame is installed in a circular hole. A vibration damping component is threadedly connected to the end of the buffer away from the H-shaped frame. A sliding groove is formed on the annular inner surface of the circular groove, and the vibration damping component is slidably connected in the sliding groove.

[0003] However, during actual use, the applicant found that the vibration damping of the speaker body was achieved by setting a first elastic element and multiple second elastic elements. In this process, since the first elastic element and the second elastic element cannot quickly convert and weaken the vibration, the first elastic element and the second elastic element will be compressed and released back and forth for a long time, which makes the speaker body unstable. In view of this, we propose a vibration damping structure for the speaker. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to a vibration damping structure for a loudspeaker, comprising a loudspeaker body, a protective shell surrounding the loudspeaker body, slide rails symmetrically fixed on the inner wall of the protective shell, a connecting seat fixedly mounted at the rear end of the loudspeaker body, a vibration damping bracket fixedly mounted on the connecting seat by bolts and nuts, a vibration damping pad fixedly connected to the inner wall of the vibration damping bracket, a rod sleeve fixedly mounted on the outer wall of the vibration damping bracket, a sliding rod slidably connected within the rod sleeve, a vibration damping slide block fixedly connected to the end of the sliding rod outside the rod sleeve, the vibration damping slide block being elastically connected to the rod sleeve by a spring, the vibration damping slide block sliding along the rod sleeve, and a dustproof net fixedly mounted on the front side of the protective shell.

[0006] Preferably, the vibration damping bracket is U-shaped, and connecting ears are symmetrically arranged at both ends of the vibration damping bracket.

[0007] Preferably, the connecting seat has a slot, the vibration damping bracket is inserted into the slot, and the inner wall of the vibration damping pad abuts against the connecting seat.

[0010] Preferably, a limiting plate is fixedly provided on the outer wall of the rod sleeve, one end of the spring abuts against the limiting plate, and the other end of the spring abuts against the vibration damping slide.

[0011] This utility model has the following beneficial effects:

[0012] This utility model discloses a vibration damping structure for a loudspeaker. By setting a vibration damping bracket, when the loudspeaker body vibrates, the vibration damping slide can slide along the slide rail, converting the kinetic energy of the vibration into heat to weaken it, thereby achieving vibration damping of the loudspeaker body. This makes the loudspeaker more stable during use and reduces the damage caused by vibration. The vibration damping pad, together with the slide rail and the vibration damping slide, can achieve dual vibration damping of the loudspeaker, resulting in better vibration damping effect.

[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 As shown, this utility model provides a technical solution:

[0022] A vibration damping structure for a loudspeaker includes a loudspeaker body 1, a protective shell 2 on the outside of the loudspeaker body 1, slide rails 22 symmetrically fixed on the inner sidewall of the protective shell 2, a connecting seat 11 fixedly fixed at the rear end of the loudspeaker body 1, a vibration damping bracket 3 locked and fixed on the connecting seat 11 by bolts 4 and nuts 5, the vibration damping bracket 3 being U-shaped, with connecting ears 31 symmetrically arranged at both ends of the vibration damping bracket 3, and a slot 111 formed on the connecting seat 11, in which the vibration damping bracket 3 is engaged. A vibration damping pad 7 is fixedly connected to the inner wall of the frame 3. The inner wall of the vibration damping pad 7 abuts against the connecting seat 11. One end of the bolt 4 passes through the connecting lugs 31 on the two vibration damping brackets 3 in sequence, and one end of the bolt 4 is threadedly engaged with the nut 5. A rod sleeve 32 is fixedly installed on the outer wall of the vibration damping bracket 3. A sliding rod 33 is slidably connected in the rod sleeve 32. A limit slider 331 is provided at one end of the sliding rod 33 inside the rod sleeve 32, and the limit slider 331 slides along the limit groove opened inside the rod sleeve 32. A vibration damping slide 34 is fixedly connected to one end of the rod sleeve 32. The vibration damping slide 34 is elastically connected to the rod sleeve 32 via a spring 6. A limit plate 321 is fixedly provided on the outer wall of the rod sleeve 32. One end of the spring 6 abuts against the limit plate 321, and the other end of the spring 6 abuts against the vibration damping slide 34. The vibration damping slide 34 slides along the rod sleeve 32. Both the vibration damping slide 34 and the rod sleeve 32 are provided with anti-slip textures. The setting of the spring 6 ensures that the vibration damping slide 34 can always effectively contact the slide rail 22. The vibration damping bracket 3 can cause the vibration damping slide 34 to slide along the slide rail 22 when the speaker body 1 vibrates, converting the kinetic energy of the vibration into heat to weaken it, thereby achieving vibration damping of the speaker body 1, making the speaker more stable during use and reducing the damage caused by vibration to the speaker. The vibration damping pad 7 can work with the slide rail 22 and the vibration damping slide 34 to achieve double vibration damping of the speaker, with better vibration damping effect. A dustproof net 21 is fixedly installed on the front side of the protective shell 2.

[0023] Working principle: When the speaker body 1 vibrates during operation, the vibration of the speaker body 1 can drive the vibration damping bracket 3 to vibrate together. At this time, the vibration damping pad 7 can realize the primary vibration damping of the speaker body 1. The vibration of the vibration damping bracket 3 can drive the rod sleeve 32 and the slide rod 33 to vibrate together. The vibration of the slide rod 33 can drive the vibration damping slide 34 to vibrate and make the vibration damping slide 34 slide along the slide rail 22. At this time, the vibration damping slide 34 can convert the kinetic energy of the vibration into heat by sliding along the slide rail 22, thereby reducing the vibration. This can achieve secondary vibration damping of the speaker body 1, making the speaker body 1 more stable during operation and reducing the damage caused by vibration to the speaker.
