Description

Technical Field

[0001] This utility model relates to the field of loudspeaker technology, specifically to a shockproof and drop-resistant loudspeaker. Background Technology

[0002] A loudspeaker is actually a device that converts electrical energy into sound. When different electronic energies are transmitted to the coil, the coil generates an energy that interacts with the magnetic field of the magnet. This interaction causes the diaphragm to vibrate. Because the electronic energy changes constantly, the loudspeaker's coil will move forward or backward, and thus the loudspeaker's diaphragm will move accordingly. These movements cause changes in the density of the air, which produces sound. Existing loudspeakers have poor shock resistance and drop protection, and are easily damaged.

[0003] An existing shockproof and drop-proof speaker, such as the one described in Chinese patent application number CN202020790938.9, includes a shell and a speaker body. A spherical groove is fixedly provided in the middle of the top of the shell, and the speaker body is fixedly installed on the bottom side inside the spherical groove. A drop-proof structure is fixedly provided on the top of the spherical groove. However, although the existing shockproof and drop-proof speaker has a shock-absorbing structure, it can only provide shock absorption in one direction, which is not very effective. If it is dropped, the direction of impact cannot be controlled, resulting in poor protection for the speaker.

[0004] Therefore, we proposed a shockproof and drop-resistant speaker to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a shockproof and drop-resistant speaker to solve the problem mentioned in the background art that although existing shockproof and drop-resistant speakers have a shock-absorbing structure, their unidirectional shock-absorbing effect is poor and they cannot provide comprehensive protection.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a shockproof and drop-resistant speaker, comprising a speaker housing, a protective cover, and a speaker body:

[0007] The front end of the speaker housing is equipped with a protective cover, and the speaker body is provided inside the speaker housing. The speaker body is connected to a positioning seat, and the rear end of the positioning seat is connected to a positioning shaft.

[0008] A positioning link is passed through the upper end of the positioning shaft. A positioning ring is provided on the outside of the speaker body, and the positioning link is embedded inside the positioning ring. A spring piece passes through the outside of the positioning link, and sliding rods are fixed at both ends of the spring piece.

[0009] Preferably, a buffer spring is sleeved on the outside of the positioning shaft, and the buffer springs are symmetrically distributed on both sides of the positioning link, with the two ends of the buffer springs connected to the positioning link and the positioning shaft respectively.

[0010] By adopting the above technical solution, the design of the buffer spring can buffer and absorb energy when the speaker body is subjected to horizontal impact or collision. The design of two sets of buffer springs can prevent the speaker body from shaking back and forth after absorbing energy.

[0011] Preferably, the positioning base and the positioning shaft are arranged in a circular array with the center point of the horn body as the axis.

[0012] By adopting the above technical solution, the design of multiple positioning seats and positioning shafts can achieve a buffering effect in multiple directions.

[0013] Preferably, a limiting rod is fixed at the upper end of the positioning link, a limiting groove is formed on the outer wall of the positioning ring, and both ends of the limiting rod extend into the limiting groove, and the limiting groove is distributed in a ring array.

[0014] By adopting the above technical solution, the range of motion of the positioning link and its stability during movement can be improved through the cooperation of the limiting groove and the limiting rod.

[0015] Preferably, the inner wall of the positioning ring is provided with a sliding groove, and both ends of the sliding rod extend into the sliding groove. The sliding rod is slidably connected to the sliding groove, and the sliding rod contacts the outer end of the spring piece.

[0016] By adopting the above technical solution, through the design of the sliding rod and the spring, the spring can be deformed and absorb energy when the horn is impacted or collided. At the same time, the cooperation between the sliding groove and the sliding rod can limit the range of motion and stability of the spring.

[0017] Preferably, the inner wall of the speaker housing is symmetrically fixed with mounting bases, and the front end of the mounting base is threaded with a positioning bolt. The positioning ring has a positioning hole on its outside, and the positioning bolt passes through the positioning hole.

[0018] By adopting the above technical solution, the positioning bolts and positioning holes are designed to connect and fix the mounting base and the positioning ring, and then the mounting base is used to install the positioning ring and the speaker body structure inside the speaker housing.

[0019] Compared with the prior art, the beneficial effects of this utility model are: the impact-resistant and shockproof speaker;

[0020] 1. It is equipped with a multi-directional buffer and shock absorption structure, which can effectively protect the speaker body when the speaker shell is impacted or collided, absorb the energy of the impact, avoid damage to the speaker body from vibration, and improve the service life of the speaker body.

[0021] 2. The energy-absorbing buffer structure with a ring array design, together with the positioning ring, is used to install the speaker body, thereby protecting the speaker body from multiple directions. With the addition of a horizontal buffer structure, the protection effect is better when the speaker is dropped, and it is not limited by the drop angle. Attached Figure Description
