Description

Technical Field

[0001] This application relates to the field of audio equipment technology, and in particular to a buffer structure and a power amplifier. Background Technology

[0002] A power amplifier is a pulsed power amplifier capable of generating maximum power output to drive a specific load. During operation, the high power output of a power amplifier generates vibrations, which can easily cause resonance between its casing and the surface it's placed on, resulting in noticeable noise. Furthermore, power amplifiers are often used in conjunction with speakers. However, the vibrations generated by the speakers are transmitted to the power amplifier, causing it to vibrate during operation and potentially leading to loosening or even damage to internal electrical components. Currently, the industry commonly uses elastic coils to buffer vibrations, but these have poor actual damping capacity, negatively impacting the power amplifier. Utility Model Content

[0019] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0020] In the description of this application, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation or be constructed or operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0021] In the description of this application, if there are short sentences containing multiple parallel features, the modifiers in these sentences define the closest feature. For example, "B, C, and E connected to D are set on A," means that B is set on A, E is connected to D, and C is not defined. However, modifiers indicating the relationship between features, such as "interval setting" or "circular arrangement," do not fall into this category. In sentences where the subject is omitted, the omitted subject is the subject of the preceding sentence; that is, "A has B and includes C" means that A has B and A includes C.

[0022] In the description of this application, unless otherwise expressly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.

[0023] The following is combined Figures 1 to 4 The embodiments of this utility model are described below.

[0024] When a power amplifier is in operation, it will vibrate slightly due to its output. The vibration can be more noticeable when it is close to the audio equipment due to the lightness or heaviness of the rhythm. Therefore, vibration damping pads are often installed on the bottom of these devices to prevent the power amplifier from shifting or tipping over due to shaking and affecting the listening quality. The current power amplifier buffer structure mostly uses a combination of feet and rubber pads. The feet need to be adjusted in height and fixed in position separately. Over time, they will deform. The structure is complex and the installation is cumbersome.

[0025] Based on this, this application provides a buffer structure, which includes a cover 110, the cover 110 having a receiving cavity with a lower opening, and a downwardly extending connecting rod 320 fixed in the receiving cavity.

[0026] The buffer assembly 200 includes a base 210, an elastic element 220, and a damping element 230. The damping element 230 is fixed to the base 210, and the elastic element 220 is arranged around the outside of the damping element 230. The top of the damping element 230 has a connecting hole, and the connecting rod 320 is slidably inserted into the connecting hole. The damping element 230 has a connecting layer with a connecting hole. When the elastic element 220 is a spring, it first undergoes compression or tension deformation. This elastic deformation reduces the intensity of the vibration impact. Combined with the damping element 230, the remaining vibration energy is dissipated through the internal damping medium or structure, reducing vibration transmission and preventing repeated vibration transmission caused by the elastic element 220's repeated rebound. The connecting rod 320 slides along the connecting hole, limiting the relative movement direction between the cover 110 and the buffer assembly 200, allowing vibration to be transmitted vertically to the cover 110, thereby effectively reducing the vibration experienced by the power amplifier. It should be noted that the damping component 230 can use existing damping structures, as long as they can be adapted to the base 210 for installation.

[0027] Therefore, by connecting the connecting rod 320 inside the housing 110 and engaging the connecting hole on the buffer assembly 200, the two can be combined into a single unit with a simple overall structure, eliminating the need for complex foot spikes to achieve the buffering and shock absorption function. When external vibrations occur, the vibrations pass sequentially through the buffer assembly 200 and the housing, providing conditions for the amplifier to effectively buffer and reduce vibrations, thus protecting the precision components such as the circuit boards inside the unit 100 and preventing components from becoming loose or falling off due to vibrations.

[0028] In some embodiments, the buffer assembly 200 further includes a gasket 240, which is fixedly connected to the top of the elastic member 220. The gasket 240 has a mounting hole through which the connecting rod 320 passes and connects to the damping member 230, thereby providing a guide and support point for the connecting rod 320, making its up-and-down movement more stable and reducing jamming. The gasket 240 can evenly distribute pressure or elastic force across the entire end face, preventing the end of the elastic member 220 from wearing or deforming due to long-term localized stress, thus extending its service life. In addition, it can also prevent the elastic member 220 from shifting or being damaged during vibration, thereby improving the reliability of the buffer structure and further optimizing the structure and performance of the buffer assembly 200.

[0029] In some embodiments, the buffer structure further includes a stop 300, which is annular and disposed within the receiving cavity, with the connecting rod 320 fixed to the stop 300. The stop 300 is placed within the receiving cavity of the cover 110, the connecting rod 320 is fixed to the stop 300, and then the buffer assembly 200 is connected to the cover 110.

[0030] Optionally, the stop 300 and the cover 110 are integrally formed. This reduces assembly steps and improves assembly efficiency. Alternatively, the stop 300 has a protrusion 310 at its top, with an external thread 311 on the protrusion 310. The cover 110 has a corresponding connection port inside the protrusion 310, with an internal thread on the inner wall of the connection port. The cover 110 is threadedly connected to the protrusion 310. This allows the buffer structure to be easily disassembled for replacement or repair of other internal components, improving product maintainability.

[0031] In some embodiments, a plurality of buffer washers 400 are sleeved on the outer edge of the elastic element. The buffer washers 400 are sleeved and fixed along the outer edge of the elastic element structure, so as to further increase the buffering effect of the elastic element through the buffer washers 400, absorb more vibration energy through their own deformation, and at the same time, protect the elastic element.

[0032] In some embodiments, a silicone pad and a sponge pad are sequentially bonded and fixed to the bottom of the base from bottom to top. The silicone pad has good elasticity and wear resistance, preventing the power amplifier from sliding on a smooth surface. The sponge pad has good flexibility, providing initial cushioning through the silicone pad and then secondary cushioning through the sponge pad, further buffering and absorbing vibrations.

[0033] like Figure 1 As shown, this application also provides a power amplifier, which includes a body 100 and a buffer structure as described in any of the above embodiments, the buffer structure being installed at the bottom of the body. Therefore, this power amplifier combines the technical advantages of the buffer structure disclosed in the embodiments of this application. At the same time, the buffer structure has strong versatility, eliminating the need to adjust the height of the feet according to the power amplifier model, and can be adapted to power amplifier bodies of different sizes.
