Description

Technical Field

[0001] The utility model relates to the technical field of high-frequency loudspeakers, in particular to a single-piece membrane high-frequency loudspeaker. Background Technique

[0002] A high-frequency loudspeaker refers to a loudspeaker specifically designed to generate high-frequency sounds. Such a loudspeaker usually has the characteristics of being small and light, aiming to generate high-frequency sound waves. A single-piece membrane high-frequency loudspeaker refers to a high-frequency loudspeaker using a single-layer planar diaphragm. The characteristic of a single-piece membrane high-frequency loudspeaker is the use of a single-layer planar diaphragm. This design helps to improve the reproduction effect of high-frequency signals. Compared with traditional dome-shaped or other forms of diaphragms, the planar diaphragm may be more excellent in high-frequency response and can provide clearer and more accurate high-frequency performance. In order to improve the use efficiency of high-frequency loudspeakers, a single-piece membrane high-frequency loudspeaker is required. However, the existing single-piece membrane high-frequency loudspeakers still have the following deficiencies:

[0003] For example, the utility model with the publication number CN221127484U discloses a high-frequency loudspeaker structure. In this utility model, a rubber ring is arranged on the outer side of the loudspeaker body in front of the mounting block, and the rubber ring is in contact with the groove, so that the screws tightened on the mounting block can be blocked when viewed from the front side of the speaker panel, thus avoiding the unsightly situation of the screws being exposed outside. And convex bodies are arranged on the rubber ring to facilitate pulling, so as not to affect the disassembly and assembly of the screws. However, for comparative documents similar to the above application, when the existing single-piece membrane high-frequency loudspeakers are in use, since most single-piece membrane high-frequency loudspeakers are a large integral structure, it is inconvenient to store the single-piece membrane high-frequency loudspeakers and they are prone to being toppled by external forces during use, resulting in the problems of decreased practicability and reduced use efficiency of the single-piece membrane high-frequency loudspeakers.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a single-piece membrane high-frequency loudspeaker is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a single-piece membrane high-frequency loudspeaker to solve the problems put forward in the above background technique.

[0006] To achieve the above object, the present utility model provides the following technical solutions: A single-film high-frequency loudspeaker, comprising a main frame body and a mounting assembly. Limited-sliding grooves are provided on both sides of the lower end of the main frame body. An installation assembly is provided at the lower end of the main frame body, and the installation assembly includes an installation frame, a docking groove, a limit slider, a threaded installation groove, a threaded rotating rod, an auxiliary rotating handle, a receiving block, and a universal wheel. A docking groove is provided in the middle of the installation frame, and limit sliders are additionally provided on both sides inside the docking groove. Threaded installation grooves are provided at both ends inside the installation frame, and threaded rotating rods are connected inside the threaded installation grooves. An auxiliary rotating handle is additionally provided at the upper end of the threaded rotating rod. At the same time, a receiving block is installed at the lower end of the threaded rotating rod. Universal wheels are installed on both sides of the lower end of the installation frame. A sounding assembly is provided inside the main frame body.

[0007] Further, the external dimension of the limit slider is adapted to the internal dimension of the limited-sliding groove, and the limit slider is slidably connected to the main frame body through the limited-sliding groove.

[0008] Further, the external dimension of the threaded rotating rod is adapted to the internal dimension of the threaded installation groove, and the threaded rotating rod is rotatably connected to the installation frame through the threaded installation groove.

[0009] Further, the number of the threaded rotating rods is set to four, and two of the threaded rotating rods are in a group. And each group of the threaded rotating rods is symmetrically arranged on both sides of the lower end of the main frame body with respect to the front central axis of the main frame body.

[0010] Further, the sounding assembly includes an installation through groove, a diaphragm main body, and a limit groove. The diaphragm main body is connected to the middle of the installation through groove. Limit grooves are provided on both sides inside the main frame body.

[0011] Further, the sounding assembly further includes a docking block, a mounting bolt, and a permanent magnet plate. A docking block is connected inside the limit groove. At the same time, a mounting bolt is connected inside the docking block. A permanent magnet plate is installed outside the docking block.

[0012] Further, the external dimension of the diaphragm main body is adapted to the internal dimension of the installation through groove, and the diaphragm main body is embeddedly connected to the main frame body through the installation through groove.

[0013] Further, the internal dimension of the limit groove is adapted to the external dimension of the docking block, and the docking block is connected to the main frame body through the limit groove.

[0014] The present utility model provides a single-film high-frequency loudspeaker, which has the following beneficial effects:

[0015] 1. Through the arrangement of the mounting assembly, when the single-membrane high-frequency speaker is in use, the threaded rod can be rotated by the auxiliary handle, causing the receiving block to move downward and contact the ground, thereby increasing the stability of the mounting bracket during use. The main frame is slidably installed inside the mounting bracket through the docking groove. At the same time, the limiting chute cooperates with the limiting slider to avoid position deviation during the sliding installation, enabling the main frame to increase its stability during use through the mounting bracket. The universal wheels installed at the bottom of the mounting bracket facilitate the movement of the main frame, thus enhancing the overall practicality and usage efficiency of the high-frequency speaker.

[0016] 2. Through the arrangement of the sound-generating assembly, when the single-membrane high-frequency speaker is in use, the diaphragm main body can be installed inside the main frame through the installation through groove opened inside the main frame. The permanent magnet plates are installed on both outer sides of the diaphragm main body by using the limiting groove and the docking block. At the same time, the permanent magnet plates are fixedly installed on the main frame by using the mounting bolts connected inside the docking block. The two permanent magnet plates form a uniform magnetic field using a magnetic conductive bracket and are installed with opposite polarities, sandwiching the diaphragm main body in the middle. The diaphragm main body is composed of a yellow flexible circuit board with serpentine lines printed on it. After being energized, it will generate a magnetic field and interact with the magnetic plates, thereby vibrating, and further enhancing the overall usage efficiency of the high-frequency speaker.
