[0002] A power amplifier is a device that uses a small signal to drive a high-power load (typical high-power loads include speakers, motors, wireless transmission antennas, etc.). This type of amplifier circuit that can amplify a small input signal to drive a large load is called a power amplifier, or simply a PA. The voltage and current output by the power amplifier that can drive a high-power load is sometimes called a "large signal". Power amplifiers are often found in our daily lives and are extremely important devices.

The power amplifier of the technical solution of the utility model is stably installed in the shell through the locking assembly, which not only prevents the power amplifier from shaking, but also avoids the use of a large number of screws to cause complicated disassembly and assembly. Since power amplifiers are needed for both experiments and control systems, and due to the complexity of the application environment, users may drop the power amplifiers. Power amplifiers that lack protection from protective components are prone to damage, causing trouble to users.

DETAILED DESCRIPTION

[0021] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1

[0023] See also Figure 1-Figure 3 The utility model provides a technical solution: the power amplifier with a protective structure includes: a body 1, an end cover 2 and a protective block 6, the end of the body 1 is embedded with the end cover 2, and the end cover 2 and the body 1 are fixed with screws, and protective handles 5 for blocking protection are welded on both sides of the end cover 2, and a protective block 6 is embedded between the end covers 2 on both sides, and one side of the protective block 6 is fitted along one side of the body 1, the height dimension of the protective block 6 is greater than the height dimension of the body 1, and the protective block 6 raises the body 1, and the protective blocks 6 on both sides are in contact with the ground to separate the bottom of the body 1 from the ground, the inner wall of the protective block 6 is embedded with a buffer partition 61 for buffer protection, and the connection between the buffer partition 61 and the protective block 6 is sleeved with a sealing strip 62 for sealing protection, and the connection between the protective block 6 and the end covers 2 at both ends is threadedly connected with a fastening bolt 4.

[0024] Embodiment 2

[0025] On the basis of the first embodiment, inner heat dissipation holes 11 for heat dissipation protection are provided on both sides of the outer wall of the body 1, and a plurality of outer heat dissipation holes 63 are provided on the inner wall of the buffer partition 61, and the outer heat dissipation holes 63 and the inner heat dissipation holes 11 overlap with each other. The entire protective block 6 serves as the left protective component of the body 1. Since the height dimension of the protective block 6 is greater than the height dimension of the body 1, the protective block 6 raises the body 1, and the bottom of the body 1 does not contact the ground. When the body 1 falls, the protective block 6 contacts the ground first. At the same time, a buffer partition 61 is provided on the inner wall of the protective block 6. The material of the buffer partition 61 includes rubber, latex, ACF metamaterial, polyurethane foam, EVA material, etc. It can play a good shock-absorbing and buffering role, reduce the impact caused by the fall of the body 1, and play a certain protective function. End covers 2 are also provided at both ends of the body 1, and protective handles 5 are distributed on both sides of the end cover 2. The ends of the body 1 are protected by the protective handles 5, which can further improve the protection ability of the body 1, meet the all-round protection of the body 1, and ensure that the body 1 can be used normally. At the same time, since the protective handles 5 first contact the wall, when the body 1 is placed, when the rear end of the body 1 is connected to the wire, there is a preventive space between the protective handles 5 on both sides, which meets the requirement of buffering the bending angle of the wire and the wall, and reduces the possibility of damage caused by large-angle bending of the connected wire.

[0026] Embodiment 3

[0027] On the basis of the second embodiment, the front end of the body 1 is equipped with a control panel 3 for controlling the power amplifier. The body 1 is provided with a through hole 22 along the contact position of the control panel 3, and a friction sleeve 23 is fitted along the inner side of the body 1 along the through hole 22. The friction sleeve 23 is threadedly connected to the output end shaft of the control panel 3, and the friction sleeve 23 increases the friction coefficient between the output end shaft and the end cover 2. The two ends of the end cover 2 are bent with side plates 21, and the side plates 21 are fitted along the upper and lower ends of the body 1. The end shaft of the control button of the control panel 3 is connected to the friction sleeve 23 by a threaded connection. The surface of the friction sleeve 23 adopts a friction pattern design that provides friction. When the user rotates the control button, its end shaft is subjected to the friction force of the friction sleeve 23 and is slightly rotated at a slow speed, which satisfies the effect of the user fine-tuning the power amplifier, and the side plate 21 has a certain protective effect. The side plate 21 protects the upper and lower ends of the body 1, reduces the entry of liquid from the gap between the body 1 and the end cover 2, and further improves the protective effect of the body 1.

[0028] In actual use, the end cover 2 is fixed to the two ends of the body 1 by bolt fastening, and the friction sleeve 23 is threadedly connected to the output end shaft of the control panel 3. The friction sleeve 23 is fitted on the inner wall side of the end cover 2. At this time, the protective block 6 is embedded between the end covers 2 on both sides, and the connection is connected by fastening bolts 4. At the same time, the outer heat dissipation holes 63 in the buffer partition 61 are aligned with the inner heat dissipation holes 11 of the body 1, and the two overlap with each other to ensure that the body 1 can dissipate heat normally. Then the body 1 is moved to a suitable position. Since the height dimension of its protective block 6 is greater than the height dimension of the body 1, the protective block 6 raises the body 1, and the bottom of the body 1 does not contact the ground. When the body 1 falls, the protective block 6 first contacts the ground. At the same time, a buffer partition 61 is arranged on the inner wall of the protective block 6, which can play a good shock-absorbing and buffering role and reduce the impact caused by the fall of the body 1. Finally, the user intervenes in the input wire and controls the body 1 through the control panel 3.
