[0001] This utility model relates to the field of power amplifier technology, and in particular to a power amplifier device for handheld electronic devices. Background Technology
[0002] A power amplifier (or simply "amplifier") is an amplifier that can produce maximum power output to drive a load (such as a loudspeaker) under a given distortion rate. The power amplifier plays a pivotal role in the entire audio system, acting as a coordinator and, to a certain extent, determining whether the system can provide good sound quality.
[0003] In the present technology, power amplifier devices are often fixed in one position during use. However, in actual use, the operator needs to move the device by hand. Since the power amplifier device has a certain weight, it will cause arm pain for the operator when holding it for a long time, which reduces its practicality. In order to address the above problems, a handheld electronic device power amplifier device is proposed. Utility Model Content

Detailed Implementation
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Example: Reference Figures 1-6 The handheld electronic device power amplifier shown includes a power amplifier body 1, a placement mechanism at the bottom of the power amplifier body 1 for protecting the power amplifier body 1, and a floating mechanism at the top of the power amplifier body 1 for suspending the power amplifier body 1.
[0027] The placement mechanism includes a U-shaped mounting plate 2. The power amplifier body 1 is set on the top inner wall of the U-shaped mounting plate 2 by two limiting components. Multiple buffer grooves are opened at the bottom of the U-shaped mounting plate 2. Buffer columns 6 are slidably installed in each of the multiple buffer grooves. Elastic components are set at the top of each of the multiple buffer columns 6. Two mounting grooves are opened at the top of the U-shaped mounting plate 2. A mounting shaft is fixedly installed on the opposite inner walls of one of the mounting grooves. A flip plate 9 is rotatably sleeved on the mounting shaft. The flip plate 9 is connected to the U-shaped mounting plate 2 by a fastening component. A hand-held component is set on the side of the flip plate 9.
[0028] The floating mechanism includes a hydrogen balloon 14, a fixing ring 11 is provided on the top of the flip plate 9, a steel wire rope 13 is provided on the fixing ring 11, and the other end of the steel wire rope 13 is connected to the hydrogen balloon 14.
[0029] With the above structure, when in use, the amplifier body 1 is first placed on the top inner wall of the U-shaped mounting plate 2 and fixed by two limiting components. Then, the flip plate 9 is rotated and connected to the U-shaped mounting plate 2 by the fastening components. Then, hydrogen is filled into the hydrogen balloon 14. When it is filled to a certain extent, it causes the amplifier body 1 and the U-shaped mounting plate 2 to float. The staff can stabilize it by holding the component to prevent it from tipping over and falling, which greatly reduces the burden on the staff when holding it for a long time.
[0030] like Figure 2 and Figure 3 As shown, the limiting component includes an L-shaped limiting block 3, and a sliding hole 16 is provided at the bottom of the U-shaped mounting plate 2. The L-shaped limiting block 3 is slidably installed in the sliding hole 16 through a guide unit. The bottom of the power amplifier body 1 is provided with an L-shaped limiting hole 17 that matches the L-shaped limiting block 3. Through the snap-fit function between the L-shaped limiting block 3 and the L-shaped limiting hole 17, the power amplifier body 1 and the U-shaped mounting plate 2 are snap-fit connected. The guide unit includes a limiting rod 4. The two ends of the limiting rod 4 are respectively fixedly installed on the opposite inner walls of the sliding hole 16. A limiting hole is provided on the side of the L-shaped limiting block 3. The limiting rod 4 is slidably installed in the limiting hole. A compression spring 5 is sleeved on the limiting rod 4. One end of the compression spring 5 is fixedly installed on the side of the L-shaped limiting block 3, and the other end of the compression spring 5 is fixedly installed on the inner wall of the side of the sliding hole 16.
[0031] Specifically, the two L-shaped limiting blocks 3 move in opposite directions, compressing the two compression springs 5 respectively. Then, the power amplifier body 1 is placed on the top inner wall of the U-shaped mounting plate 2, and the limiting of the L-shaped limiting blocks 3 is released, allowing them to reset under the elastic action of the compression springs 5, thereby engaging with the L-shaped limiting hole 17 to achieve the fixing function. The entire fixing operation is convenient and has strong stability.
[0032] like Figure 4As shown, the elastic component includes a buffer spring 7. By setting the buffer spring 7, when the U-shaped mounting plate 2 is placed, its elasticity can play a certain buffering function on the buffer column 6 to prevent damage caused by vibration. The bottom end of the buffer spring 7 is fixedly installed on the top end of the buffer column 6, and the top end of the buffer spring 7 is fixedly installed on the top inner wall of the buffer groove. A buffer pad 8 is fixedly installed at the bottom end of the buffer column 6.
[0033] Specifically, after use, the U-shaped mounting plate 2 moves downward. When multiple buffer columns 6 come into contact with the ground, the elastic action of multiple buffer springs 7 achieves the buffer protection function, thereby protecting the main body of the power amplifier 1.
[0034] like Figure 6 As shown, the fastening assembly includes a fastening bolt 10. The top of the flip plate 9 has a threaded hole, and the bottom inner wall of one of the mounting slots has a threaded groove. The fastening bolt 10 is threaded into the threaded hole and the threaded groove. Through the connection between the fastening bolt 10 and the threaded hole and the threaded groove, the flip plate 9 and the U-shaped mounting plate 2 can be fixedly connected.
[0035] Specifically, after placing the power amplifier body 1, the flip plate 9 is rotated to rotate it into the mounting slot, and then fixed by the connection of the fastening bolts 10.
[0036] like Figure 6 As shown, the handheld assembly includes a U-shaped handle 12, which can stabilize the device in a floating state. The U-shaped handle 12 is fixedly installed on the side of the flip plate 9, and multiple heat dissipation holes 15 are provided on the opposite inner walls of the U-shaped mounting plate 2.
[0037] Specifically, during use, the hydrogen balloon 14 causes the main body of the power amplifier 1 to float, and the U-shaped handle 12 enables the staff to control and stabilize the operation.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
