Description

Technical Field

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

[0002] A speaker is a device that converts electrical signals into sound. It is widely used in audio systems. Its internal structure mainly includes T-iron, magnet, washer, basin, spring, diaphragm, voice coil, cone, etc. The basin serves as a supporting structure to fix other structures. When the speaker is working, the current passes through the coil in the T-iron to generate a magnetic field, which interacts with the magnet to generate a force to drive the diaphragm to vibrate. The diaphragm is connected to the T-iron through the spring and is fixed to the basin. The elasticity of the spring allows the diaphragm to vibrate freely. When the diaphragm vibrates, the air is compressed and released, realizing the conversion of electrical energy into sound energy.

[0003] In conventional speakers, the spider is fixed to the basin frame with adhesive to ensure that the spider remains firmly connected during long-term use, so as to properly support the diaphragm and T-iron and maintain their linear motion, thereby ensuring the audio performance and durability of the speaker. However, when the speaker is working, the diaphragm continues to vibrate, and the vibration is transmitted to the spider, which then vibrates. After the speaker has been working for a long time, the spider may partially fall off, affecting the sound quality of the speaker.

[0004] In order to ensure the long-term working stability of the elastic wave in the speaker assembly, you can choose to use adhesive to repair it, or separate the old elastic wave and re-glue a new one. The first method is more troublesome and may contaminate other components in the speaker during bonding. The second method leads to an increase in cost, and both methods have certain limitations. Utility Model Content

[0005] In order to ensure the long-term working stability of the elastic wave in the speaker assembly, the present application provides a speaker assembly reinforced with an elastic wave.

[0006] The present application provides a spring-reinforced loudspeaker assembly that adopts the following technical solution:

[0007] A speaker assembly reinforced with a spring-loaded elastic wave comprises a basin frame, the upper end of the middle portion of the basin frame is detachably connected to a spring-loaded elastic wave, the spring-loaded elastic wave comprises a main body and a connecting ring connected to the outer periphery of the main body, the upper end of the connecting ring is detachably connected to a pressure ring, the axes of the basin frame, the spring-loaded elastic wave and the pressure ring are coaxial, and the pressure ring is detachably connected circumferentially to fixing screws that simultaneously insert the pressure ring, the connecting ring and the basin frame.

[0008] By adopting the above technical solution, the spring wave is pressed against the upper end of the basin frame by using a pressure ring, and then the basin frame, the spring wave and the pressure ring are detachably connected by using fixing screws. When the speaker needs to be repaired, you can choose to directly retighten the fixing screws, or replace the new spring wave or pressure ring according to actual needs and then re-fix and lock it. The maintenance will not affect other structures in the speaker. The long-term working stability of the spring wave in the speaker assembly is effectively guaranteed through a simple method.

[0009] Optionally, a first embedding ring groove for embedding the connecting ring is formed at the upper end of the basin frame.

[0010] By adopting the above technical solution, the embedded annular groove serves to initially limit the position of the damper during the working process, and also improves the convenience of aligning the screw holes to install the damper.

[0011] Optionally, at least two elastic waves are vertically arranged, the pressure rings are detachably connected between adjacent elastic waves, and the upper end of the uppermost elastic wave is detachably connected to a pressure sheet.

[0012] By adopting the above technical solution, the cooperation of multiple elastic waves helps to increase the stability of the diaphragm and T-iron, control the vibration range, disperse the pressure and reduce shock, and improve the frequency response characteristics of the sound, thereby ensuring the sound quality and performance of the speaker.

[0013] Optionally, a second embedding ring groove is provided at the upper end of the pressure ring for embedding the upper layer of the elastic wave.

[0014] Optionally, the outer circumferential surface of the pressure ring abuts against the groove wall of the first embedded annular groove, and the outer circumferential surface of the pressing sheet abuts against the groove wall of the second embedded annular groove.

[0015] By adopting the above technical solution, the pressure ring and the pressing sheet are limited by the groove wall, which reduces the probability of displacement of the pressure ring and the pressing sheet, and avoids the pressure ring or the pressing sheet accidentally hitting the spring wave or driving the spring wave to move together after moving.

[0016] Optionally, the upper ends of the basin frame and the pressure ring are provided with round holes for inserting the fixing screws, and the outer side of the connecting ring is provided with straight slots for inserting the fixing screws, and the straight slots are connected to the round holes.

[0017] By adopting the above technical solution, the setting of the straight slot allows the wave damper to have a certain adjustment space during installation, which meets actual needs.

[0018] Optionally, a plurality of ventilation holes are provided at intervals on the outer circumference of the basin frame.

[0019] By adopting the above technical solution, the vents help the internal structure of the speaker to dissipate heat, prevent the speaker from overheating, and ensure the sound quality and the working life of the speaker.

[0020] In summary, the present application includes at least one of the following beneficial technical effects:

[0021] 1. Use the pressure ring to press the spring against the upper end of the basin frame, and then use the fixing screws to achieve a detachable connection between the basin frame, the spring and the pressure ring. When the speaker needs to be repaired, you can choose to directly re-tighten the fixing screws, or replace the spring or pressure ring with a new one according to actual needs and then re-fix and lock it. The maintenance will not affect other structures in the speaker. This simple method effectively ensures the long-term working stability of the spring in the speaker assembly;

[0022] 2. The combination of multiple elastic waves helps to increase the stability of the diaphragm and T-iron, control the vibration range, disperse pressure and shock absorption, and improve the frequency response characteristics of the sound, thereby ensuring the sound quality and performance of the speaker.
