Description

Technical Field

[0001] The utility model relates to the technical field of circuit boards, in particular to a karaoke audio integrated circuit board. Background Art

[0002] Nowadays, karaoke audio equipment has been widely welcomed and loved by consumers due to its entertainment and unique sound quality experience. However, as a complex system integrating multiple functions such as computing, audio processing, amplification, and even network communication, the design and performance of its core part: the integrated circuit board directly affects the performance of the entire system.

[0003] However, there are some problems in the existing karaoke audio integrated circuit board design:

[0004] Unstable structure: Existing karaoke audio integrated circuit boards may have some structural weaknesses in their design. For example, if the circuit board cannot maintain its shape and structure under instantaneous pressure or vibration, it may cause damage to the device and affect the audio performance and stability of the device.

[0005] Poor heat dissipation: If the heat generated by the device during operation is not properly handled, it will cause the chip to overheat, which will seriously affect the performance and service life of the device. Many existing integrated circuit boards do not have adequate heat dissipation design, so that under continuous use, the internal components may suffer performance degradation or even damage due to overheating.

[0006] Poor pressure resistance: Since the integrated circuit board needs to withstand possible pressure and impact, it needs to have strong pressure resistance. However, some current designs may not perform well in this regard, causing the device to be damaged when subjected to pressure or impact.

[0007] Insufficient insulation: The insulation of the circuit board is extremely important, otherwise it may cause accidental electrical contact and even electrical safety accidents. However, some existing designs also have certain problems in providing sufficient insulation performance.

[0008] Therefore, it is necessary to develop a new type of karaoke audio integrated circuit board to provide stronger structural stability, improve heat dissipation, enhance voltage resistance and improve insulation capacity, which will help ensure the normal operation of karaoke audio equipment and provide a better user experience. Utility Model Content

[0009] In order to overcome the defects of the prior art, the purpose of the utility model is to provide a karaoke audio integrated circuit board to solve the problems raised in the above background technology.

[0010] To achieve the above object, the technical solution of the utility model is implemented as follows: a karaoke audio integrated circuit board comprises a base, an insulating plate, a circuit board body, a pressure-resistant support component and a heat dissipation component, wherein the base is fixed on the insulating plate, a cavity is provided in the base, and support plates are respectively fixed on both sides of the base, the circuit board body is embedded in the base and placed on the support plates, the pressure-resistant support component is arranged in the cavity at the bottom of the circuit board body, and the heat dissipation components are respectively arranged on the base and the insulating plate;

[0011] The pressure-resistant support assembly includes an expansion plate, a connecting column, a hollow cylinder and a piston. There are several expansion plates, and the bottoms of the expansion plates are respectively connected to connecting columns. The number of hollow cylinders corresponds to the number of expansion plates. The bottom ends of the connecting columns are passed into the corresponding hollow cylinders, and the bottom ends of the connecting columns are fixed with pistons.

[0012] The heat dissipation assembly includes a first heat dissipation groove, a second heat dissipation groove, a first inclined plate, a second inclined plate, a third inclined plate and a fourth inclined plate. The first heat dissipation groove is opened on both sides of the base, and the second heat dissipation groove is opened on the insulating plate. The first inclined plate and the second inclined plate are alternately fixed in the first heat dissipation groove, and the third inclined plate and the fourth inclined plate are also alternately fixed in the second heat dissipation groove. "S"-shaped channels are formed between the first inclined plate and the second inclined plate, and the third inclined plate and the fourth inclined plate respectively.

[0013] Preferably, locking holes are respectively provided around the insulating plate.

[0014] Preferably, the top ends of several of the expansion plates are in contact with the circuit board body.

[0015] Preferably, the hollow cylinder is fixed on the inner wall of the bottom of the cavity.

[0016] Preferably, the piston is adapted to the shape and size of the hollow cylinder.

[0017] Preferably, one end of the first heat dissipation groove and the second heat dissipation groove are connected to the cavity.

[0018] Preferably, the other ends of the first heat dissipation slot and the second heat dissipation slot are connected to the outside.

[0019] The beneficial effects of the utility model are embodied in:

[0020] Structural stability: The base of the board is fixed to the insulating board to form a solid structure. The base has a cavity inside and there are pallets on both sides, which provide additional support. The body of the board is embedded in the base, ensuring the stability of the board. This helps prevent the board from deforming or damaging during use.

[0021] Pressure resistance: Through the design of the pressure-resistant support components, including the expansion plate, connecting column, hollow cylinder and piston, the piston can squeeze the air in the hollow cylinder, increasing the pressure resistance of the circuit board during use. This is very important for protecting the components and circuits inside the circuit board, especially in equipment such as karaoke audio, which may be subject to certain pressure and impact.

[0022] Heat dissipation efficiency: The heat dissipation assembly includes a first heat dissipation slot, a second heat dissipation slot, and alternately arranged inclined plates. These inclined plates form an "S"-shaped channel, which helps to effectively dissipate heat. The first heat dissipation slot and the second heat dissipation slot are connected to the cavity and to the outside world, which allows air to flow and effectively dissipate heat. This design helps to keep the temperature of the components inside the circuit board within a safe range, improving the reliability and life of the equipment.

[0023] Insulation: The insulating board is surrounded by locking holes, which can be used to strengthen the insulation performance of the circuit board and prevent accidental electrical contact between the components on the circuit board and the external environment. This is very important for maintaining the electrical safety of the equipment.

[0024] Based on the above beneficial effects, this karaoke audio integrated circuit board has a solid structure, pressure resistance, good heat dissipation performance and insulation, is suitable for karaoke audio and other equipment, and can improve the performance and reliability of the equipment.

[0043] Embodiment 1:

[0044] Please refer to the instruction manual Figure 1-12 The utility model provides a karaoke audio integrated circuit board, specifically:

[0045] Preparation and Assembly:

[0046] Base and its components:

[0047] Base 1: First, take a base 1 made of appropriate material. There should be a cavity 3 of moderate depth in the middle of the base 1. Both sides of the base 1 should be flat, where the support plate 5 can be fixed.

[0048] Insulation board 2: Select appropriate insulation material, such as PVC or other plastic materials to make insulation board 2. Ensure that the size of insulation board 2 matches the base 1, and pre-open locking holes 4 around it.

[0049] Fix the base 1 to the insulating board 2 and ensure that it is firmly fixed. Bolts, glue or other fixing methods can be used.

[0050] Installation of circuit board:

[0051] According to the required circuit design, the circuit board body 6 is produced, and the size of the circuit board is ensured to be compatible with the cavity 3 in the base 1 and the support plate 5 .

[0052] The circuit board body 6 is embedded in the base 1 and ensured to be stably placed on the support plate 5 .

[0053] Installation of pressure-resistant support components:

[0054] The expansion plate 7 is made of a strong material, and a connecting column 8 is welded or fixed at the bottom thereof.

[0055] The hollow cylinder 9 is fixed to the bottom inner wall of the cavity 3 , ensuring that the number thereof matches that of the expansion plates 7 .

[0056] Insert the bottom end of the connecting column 8 into the corresponding hollow cylinder 9, and fix the piston 10 at the bottom end of the connecting column. Make sure that the piston 10 matches the shape and size of the inside of the hollow cylinder 9, and the piston 10 squeezes the air in the hollow cylinder 9 to increase the pressure resistance during use.

[0057] Production and installation of heat dissipation components:

[0058] First heat dissipation grooves 11 are formed on both sides of the base 1 , and second heat dissipation grooves 12 are formed on the insulating plate 2 .

[0059] The first inclined plates 13 and the second inclined plates 14 are alternately fixed in the first heat dissipation grooves 11 to form an "S"-shaped channel.

[0060] Similarly, the third inclined plates 15 and the fourth inclined plates 16 are alternately fixed in the second heat dissipation grooves 12 to form an “S”-shaped channel.

[0061] The "S" channel design allows for heat dissipation while minimizing dust ingress.

[0062] It is ensured that one end of the first heat dissipation groove 11 and the second heat dissipation groove 12 is connected to the cavity 3 , and the other end is connected to the outside.

[0063] During use, when the karaoke audio equipment is in use, the circuit board may generate heat due to the flow of current. At this time, the heat dissipation component plays a key role, allowing air to circulate through the "S"-shaped channel to help dissipate heat, thereby protecting the circuit board body 6 from damage caused by excessive temperature. At the same time, due to possible external pressure or impact, the piston in the pressure-resistant support component can squeeze the air in the hollow cylinder 9, thereby increasing the pressure resistance of the circuit board and protecting its internal components. The locking hole 4 can be used to fix this overall structure inside the karaoke audio equipment to ensure its stable and safe operation.

[0064] In summary, through the above specific implementation methods, we can obtain a karaoke audio integrated circuit board that has a stable structure, good heat dissipation effect, and sufficient pressure resistance.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
