[0002] A loudspeaker is a transducer that converts electrical signals into sound signals. Its main function is to convert electrical energy into sound waves, which generate sound waves through vibration, enabling people to hear various sounds such as music, voice, and prompts. Loudspeakers are crucial components in many devices, providing users with a variety of audio experiences.

[0003] The U-shaped iron of a speaker is the base of the speaker and one of the most important main components in an audio system. Currently used speakers, due to their shape, cannot reduce air resistance during sound fluctuations, which can easily affect sound conversion and greatly reduce the sound conversion rate.

[0004] Therefore, a novel low-air-resistance speaker U-iron is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a speaker U-shaped iron with low air resistance, in order to solve the problem mentioned in the background art that the speaker's shape makes it impossible to reduce air resistance during sound fluctuations, which can easily affect sound conversion and greatly reduce the sound conversion rate.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a low-air-resistance speaker U-shaped iron, comprising a first U-shaped iron body, a second U-shaped iron body, and a connecting body, wherein the first U-shaped iron body and the second U-shaped iron body are respectively located on both sides of the connecting body, and the connecting body and the first U-shaped iron body and the second U-shaped iron body are provided with adjustment components that can reduce air resistance;

[0007] The adjustment assembly includes a first connecting seat, a second connecting seat, a mounting block, and a heat dissipation and ventilation plate. The second connecting seat is provided through the side wall at the bottom of the first U-shaped iron body and the second U-shaped iron body. The first connecting seat is provided through both sides of the connecting body. The heat dissipation and ventilation plate is provided through the interior of the first connecting seat and the second connecting seat.

[0008] Preferably, multiple sets of mounting blocks are fixedly connected at equal intervals to the exterior of both sides of the heat dissipation and ventilation plate, and the mounting blocks are engaged and fixed inside the first connecting seat and the second connecting seat.

[0009] Preferably, a placement platform is fixedly connected to the top of the connecting body, a voice coil is provided above the placement platform, and vertical grooves are provided on the top of both the front and rear ends of the placement platform.

[0010] Preferably, an external rod is fixedly connected to both the front and rear ends of the bottom of the voice coil. The external rod passes through the interior of the slide groove, and a limiting plate is fixedly connected to the front end of the external rod. The length of the limiting plate is greater than the length of the slide groove. Two sets of connecting grooves are provided at both the front and rear ends of the placement platform.

[0011] Preferably, the rear ends of both sides of the limiting cross plate are fixedly connected with insert blocks, and the outside of the insert blocks and the inside of the connecting groove form a snap-fit ​​connection.

[0012] Preferably, a fixing seat is fixedly connected to the top of the outer sidewall of the first U-shaped iron body and the second U-shaped iron body, and the fixing seats are symmetrically distributed about the vertical center line of the connecting body.

[0013] Preferably, the fixed base has a positioning hole inside, and a positioning sleeve is fixedly connected to the inner wall of the positioning hole. The inner wall of the positioning sleeve is provided with threads.

[0014] Preferably, the top end of the positioning sleeve is provided with an installation groove, and a sealing ring is engaged with the top end of the installation groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the low air resistance speaker U-shaped iron not only achieves the function of reducing air resistance and optimizing the fixing function, but also achieves the function of convenient installation;

[0016] (1) By setting a first connecting seat, a second connecting seat, a heat dissipation and ventilation plate and mounting blocks, the heat dissipation and ventilation plate penetrates the interior of the first connecting seat, the second connecting seat and the connecting body on both sides, so that the first U iron body, the second U iron body and the connecting body can be quickly assembled and fixed together. The heat dissipation and ventilation plate itself has several holes to reduce airflow separation and uniformly discharge to the outside, thereby reducing air resistance. At the same time, the heat generated inside can be quickly discharged to avoid heat accumulation causing damage to the internal structure and affecting subsequent use, thus improving the safety of use. The length of the heat dissipation and ventilation plate can be adapted to the speaker, making the structure flexible. The heat dissipation and ventilation plate is fixed in all directions by several sets of mounting blocks using a snap-fit ​​structure.

[0017] (2) By setting a sliding groove, a limiting horizontal plate, an external rod, a plug and a connecting groove, the voice coil is installed on the top of the placement stage. The external rod passes through the inside of the sliding groove. The limiting horizontal plate can limit and fix the two ends of the voice coil. The plug can be fixed in the inside of the connecting groove by using the snap-fit ​​structure. This optimizes the connection between the voice coil and the first U iron body and the second U iron body, enhances the fixation between the voice coil and the placement stage, prevents the voice coil from falling off during use, and facilitates the disassembly and replacement of the voice coil.

[0018] (3) By providing positioning holes, fixing seats, positioning sleeves, mounting grooves and sealing rings, the outer side walls of the first U-shaped iron body and the second U-shaped iron body are fixedly connected to fixing seats. The positioning holes facilitate the installation and fixing of the overall structure, which can fix the first U-shaped iron body and the second U-shaped iron body in a suitable position, expand the application range of the structure, and guide the installation structure. The sealing rings can provide sealing protection for the outside of the installation structure and extend the service life of the installation structure. Attached Figure Description
