[0002] A sound power amplifier, that is, a power amplifier, is simply called an amplifier. It is one of the most basic devices in an audio system, commonly known as an "amplifier". Its main task is to amplify the weak electrical signals from a signal source (from a mixer in a professional audio system) to drive the speaker to emit sound. The main performance indicators of the amplifier include output power, frequency response, distortion, signal-to-noise ratio, output impedance, damping factor, etc.

[0003] Most of the audio products on the market currently only support a single installation method, such as horizontal placement or wall mounting. This design limits the flexibility of the audio in different occasions and user needs, and there are certain limitations. This design limitation makes it difficult for audio products to adapt to diverse usage scenarios, thereby reducing their applicability. At the same time, the protection of the audio itself is also poor. For this reason, a sound power amplifier is proposed. Summary of the Utility Model

[0021] 1. An audio power amplifier provided by the present utility model assembles the power amplifier body and the mounting plate by moving the movable plate so that two positioning posts on the mounting plate pass through the holes on the surface of the inserting block. Since the shape of the first mounting plate is L-shaped, it can not only isolate the power amplifier body from the ground when the power amplifier body is placed flat, playing a certain moisture-proof role, but also use components such as fixing nails to install the power amplifier body on the wall through the holes in the upper part of the first mounting plate, enabling the power amplifier body to have two different installation methods, greatly increasing the flexibility and applicability of use.

[0037] Preferably, the surface of the mounting groove assembly 3 is provided with a built-in groove 31. The inner wall of one side of the built-in groove 31 is fixedly connected with a plurality of horizontal plates 32. The plurality of horizontal plates 32 support the power amplifier body 2 to prevent it from contacting the ground, playing a moisture-proof role, and at the same time facilitating the heat dissipation at the bottom of the power amplifier body 2.

[0038] Preferably, the positioning and mounting assembly 4 includes two fixed blocks 41 and two pairs of insertion blocks 42. The two fixed blocks 41 are respectively fixed on both sides of the surface of the first mounting plate 1, and the two pairs of insertion blocks 42 are respectively fixed on both sides of the surface of the power amplifier body 2. The insertion blocks 42 have holes through which the positioning posts 45 can pass, so as to facilitate the assembly of the first mounting plate 1 and the power amplifier body 2.

[0039] Preferably, a movable plate 43 is movably sleeved on the surface of the fixed block 41. The fixed block 41 is U-shaped to prevent the movable plate 43 from separating from the surface of the fixed block 41 when moving. There is a certain frictional force between the contact surface of the movable plate 43 and the fixed block 41. One end of the movable plate 43 is fixedly connected to a mounting plate 44.

[0046] The using process of an audio power amplifier provided by the present utility model is as follows: First, the user pulls the lifting plate 51 upward until the position of the lower block 52 corresponds to the position of the moving block 72.
