Description

Technical Field

[0001] The utility model belongs to the technical field of audio equipment, and particularly relates to a shock absorber seat for placing audio equipment or connecting audio equipment prefabricated with threaded interfaces, and particularly relates to a multi-layer shock absorber seat with replaceable head nut pads or nut heads for placing or bearing audio equipment. Background Art

[0002] At present, there are very few shock absorber pads or shock absorber nails on the market that can be used for placing audio equipment with foot nails and can also be used for placing non-foot nail audio equipment. In particular, shock absorber seats that are suitable for different types of audio equipment are even rarer. However, simple shock absorber pads for placing or bearing are relatively common. However, in view of product quality, shock absorption function, and load-bearing capacity or usage scenarios, they are relatively narrow, especially not suitable for placing or reconnecting and bearing large audio equipment.

[0003] For various different types of audio equipment, in actual application scenarios, there are audio equipment with foot nails or non-foot nail audio equipment, or audio equipment prefabricated with M6, M8, M10, M12 threaded interfaces. The existing simple shock absorber pads simply cannot be used compatibly; and the existing shock absorber pads or shock absorber nails cannot control tuning, have poor shock absorption effects, etc., and cannot bear large audio equipment, such as large 400 kg floor-standing speakers.

[0004] In order to adapt to bearing different types of audio equipment and achieve the resonance frequency and shock isolation coefficient between the shock absorber seat and various different types of audio equipment. Therefore, we urgently need to innovatively design a multi-layer shock absorber seat with a combined shock absorption structure that combines metal materials and non-metal materials in hard materials. Summary of the Invention

[0005] To solve the problems that the existing shock absorber pads are not suitable for different types of audio equipment, have a single shock absorption material, poor shock absorption tuning effect, and cannot bear large audio equipment, etc., the utility model particularly provides a multi-layer shock absorber seat with replaceable head nut pads or nut heads, which can be used for flat placement or square head screw connection of audio equipment prefabricated with M6, M8, M10, M12 threaded interfaces at the bottom.

[0006] To achieve the above purpose, the concept adopted by the utility model is:

[0007] To adapt to the shock absorption of different types of audio equipment, a shock absorption seat composed of a basic ring-shaped base and a petal-shaped support seat is designed. A through-hole nut column that can connect a nut pad or a nut head is designed at the head of the shock absorption seat, and the through-hole nut column is embedded in the petal-shaped support seat. To solve the multi-layer shock absorption of different materials, a threaded bushing is designed. The ring-shaped base and the petal-shaped support seat are sleeved through the threaded bushing. When a 1-cm high threaded bushing is selected, different material damping shock absorption layers are added between the ring-shaped base and the petal-shaped support seat, thus solving the problem of the multi-layer shock absorption structure of different materials. Regarding the problem of the way of placing or bearing audio equipment, it is achieved by replacing the nut pad or the nut head. To solve the use of audio equipment with M6, M8, M10, and M12 threaded interfaces prefabricated at the bottom, the nut head is innovatively designed to be composed of a through-hole nut and a special-shaped stud. By embedding a square head screw or a square head cone pad at the head of the special-shaped stud, the problem of connecting the threaded interface at the bottom of the audio equipment is solved. Thus, by replacing the nut pad or the nut head at the head, the purpose of using shock absorption for placing or bearing different types of audio equipment is achieved.

Among them, the special-shaped stud is a metal stud composed of a large head and a small head. The large head of the stud is machined with a square counterbore, and the small head of the stud is machined with an internal hexagonal tooth; when M6, M8, M10, or M12 square head screws are embedded in the square counterbore, a shock absorber seat for reconnecting the threaded interface at the bottom of the audio equipment is formed; when a square head taper pad is embedded in the square counterbore, a shock absorber seat for placing audio equipment with foot nails is formed.

Specific embodiments

[0066] When used for audio equipment without foot nails, a non-metallic nut pad 6 is connected to the through-hole stud 5 at the head of the multi-layer structure shock-absorbing seat for use. The multi-layer shock-absorbing seat formed at this time can be used for placing audio equipment without foot nails, such as CD players, decoders, etc.; it can also be used for placing on the audio equipment cabinet, such as the cabinets of CD players, preamplifiers, digital players, etc. Since the audio equipment cabinet is prone to vibration, placing it on the cabinet can play a certain role in suppressing vibration and change the natural frequency of the original cabinet. Specific embodiments

[0067] When used for audio equipment with feet, it is used by connecting a nut head 7 with a square head cone pad 11 embedded on the through-hole nut stud 5 at the head of the multi-layer structure shock-absorbing seat. The multi-layer shock-absorbing seat thus formed can be used to pad under audio equipment with feet, such as speakers, power amplifiers, turntables, shock-absorbing racks, etc. Specific embodiments

[0068] When used for audio equipment prefabricated with M6, M8, M10, and M12 thread interfaces, it is used by connecting a nut head 7 with a square head screw 10 embedded on the through-hole nut stud 5 at the head of the multi-layer structure shock-absorbing seat. When the multi-layer shock-absorbing seat thus formed is bearing a floor-standing speaker, four shock-absorbing seats are assembled according to the prefabricated thread interfaces at the bottom of the floor-standing speaker to jointly bear a large speaker device within 400 kg as shock-absorbing foot pads. The multi-layer shock-absorbing seat is threadedly connected to the thread interface at the bottom of the floor-standing speaker, which is safer and more secure than the existing split-type shock-absorbing pads or shock-absorbing nails, thus achieving the purpose of strengthening the bearing of large floor-standing speakers.

[0069] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Any person skilled in the art, without departing from the scope of the technical solution of the present invention, may make many possible changes and modifications to the technical solution of the present invention by using the principle content disclosed above, all of which fall within the scope of the claims.
