Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0027] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0028] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0029] Please refer to Figure 1 and Figure 2 This embodiment discloses a curved ribbon loudspeaker, comprising: a diaphragm support 500 having an arc-shaped mounting frame; a diaphragm 100, which is a flexible sheet with a conductive circuit on its surface, the diaphragm 100 being mounted on the arc-shaped mounting frame and extending along the arc direction of the arc-shaped mounting frame; a front curved magnetic strip 200 disposed on the front side of the diaphragm 100 and extending along the arc direction of the arc-shaped mounting frame; a rear curved magnetic strip 300 disposed on the rear side of the diaphragm 100 and extending along the arc direction of the arc-shaped mounting frame; a rear cover support 400 adapted to mount the rear curved magnetic strip 300 and connected to the diaphragm support 500; and a front cover support 600 adapted to mount the front curved magnetic strip 200 and connected to the diaphragm support 500 or the rear cover support 400.

[0030] Specifically, in this embodiment, the diaphragm 100 is made of a metal composite insulating film, which can be bent according to design requirements. The diaphragm support 500 adopts an arc-shaped frame or two plates with arc-shaped sides arranged vertically in parallel, so that the diaphragm support 500 has an arc-shaped mounting frame. The front curved magnetic strip 200 and the rear curved magnetic strip 300 both extend along the arc direction of the arc-shaped mounting frame of the diaphragm support 500, which can form an arc-shaped magnetic field. The diaphragm 100 is mounted on the arc-shaped mounting frame of the diaphragm support 500, and the diaphragm 100 is covered with a conductive circuit. When an alternating current passes through the conductive circuit, under the action of the magnetic field, the conductive circuit will drive the diaphragm 100 to vibrate up and down, thereby pushing the air to produce sound. It should be understood that there is a certain gap between the diaphragm 100 and the front curved magnetic strip 200 and the rear curved magnetic strip 300.

[0031] Compared with the prior art, the diaphragm 100, the front curved magnetic strip 200, and the rear curved magnetic strip 300 of this embodiment all have arc-shaped structures. Furthermore, the front curved magnetic strip 200 and the rear curved magnetic strip 300 are concentrically arranged and located on both sides of the diaphragm 100, which allows the speaker to have an arc-shaped surface, increasing the diversity of speaker structures. It should be considered that, to make the speaker structure more aesthetically pleasing, both the front cover bracket 600 and the rear cover bracket 400 can have curved surface structures adapted to the arc-shaped mounting frame of the diaphragm bracket 500.

[0032] Please refer to Figure 3 and Figure 4 The front curved magnetic strips 200 are in at least one set, and the rear curved magnetic strips 300 are in the same number as the front curved magnetic strips 200, in order to form a magnetic field. By combining multiple sets of magnetic strips, the speaker can present different shapes, realizing the diversification of speaker structure. Specifically, the number of front curved magnetic strips 200 can be one, two, or three sets.

[0033] The ends of the two adjacent sets of the front curved magnetic strips 200 and the rear curved magnetic strips 300 are connected, please refer to... Figure 3 When two adjacent sets of front curved magnetic strips 200 face the same direction, they can form a larger arc-shaped structure, with the ends of the two adjacent sets of front curved magnetic strips 200 connected; please refer to Figure 4 The adjacent sets of front curved magnetic strips 200 face opposite directions, forming a strip-like structure. The ends of adjacent front curved magnetic strips 200 and rear curved magnetic strips 300 are connected. Different combinations can alter the speaker's structure, achieving greater diversity. It should be noted that within the same magnetic field group, the rear curved magnetic strip 300 faces the same direction as the front curved magnetic field to ensure a uniform and stable magnetic field. The length of the diaphragm 100 in this embodiment can be adjusted based on the number of combined magnetic strips.

[0034] Please refer to Figure 3 or Figure 4Each set of front curved magnetic strips 200 includes at least two equally spaced sub-magnetic strips 210, which ensures that the sound generated by the vibration of the diaphragm 100 can be diffused to the outside of the speaker through the gap between the sub-magnetic strips 210. In this embodiment, the number of sub-magnetic strips 210 is 3, which ensures that the width of the magnetic field meets the design requirements.

[0035] Please refer to Figure 5 Similarly, a sound amplification groove 610 is provided on the faceplate support 600 and between two adjacent sub-magnetic strips 210, which is beneficial to the diffusion of sound.

[0036] Please refer to Figure 6 and Figure 7 The diaphragm support 500 adopts an arc-shaped frame, which can prevent the diaphragm 100 from making complete contact with the diaphragm support 500, thus preserving a certain vibration space for the diaphragm 100. The diaphragm support 500 is provided with a mounting groove 510, which can be used for wiring, which helps to make the speaker wiring neat and aesthetically pleasing.

[0037] Please refer to Figures 6 to 8 To facilitate installation, flanges 620 are provided on the upper and lower sides of the faceplate bracket 600. In this embodiment, the faceplate bracket 600 is an arc-shaped frame, within which the front curved magnetic strip 200 can be installed, as well as components such as the diaphragm 100, the rear curved magnetic strip 300, and the rear cover bracket 400 can be accommodated, which helps to reduce the size of the speaker and achieve structural miniaturization. The faceplate bracket 600 can be connected to the diaphragm bracket 500 or the rear cover bracket 400 via the flanges 620. It should be considered that the flanges 620 can be provided with through holes or threaded holes to facilitate the connection between the faceplate bracket 600 and the diaphragm bracket 500 or the rear cover bracket 400.

[0038] The rear cover bracket 400 has first L-shaped steps 410 on both its upper and lower sides, and the diaphragm bracket 500 has second L-shaped steps 520 that mate with the first L-shaped steps 410. The first L-shaped steps 410 are mounted on the second L-shaped steps 520, facilitating quick alignment of the rear cover bracket 400 and the diaphragm bracket 500 and simplifying installation. During installation, after the diaphragm bracket 500 is assembled with the rear cover bracket 400, it snaps into the front cover bracket 600. Compared to threaded connections, this eliminates the need for fasteners, saving production costs and simplifying the assembly process.

[0039] To make the connection between the faceplate bracket 600 and the diaphragm bracket 500 more reliable, the faceplate bracket 600 is provided with a hook 630 and the diaphragm bracket 500 is provided with a protrusion 530, and the hook 630 engages with the protrusion 530.

[0040] Please refer to Figure 8 The rear cover bracket 400 is provided with a mounting bracket 420 for installing the rear curved magnetic strip 300. The rear curved magnetic strip 300 is snapped into the mounting bracket 420 for easy assembly.

[0041] To further simplify the assembly process, the rear cover bracket 400 and the diaphragm bracket 500 are integrated into one structure. During installation, the front cover bracket 600 snaps into the rear cover bracket 400, making the operation simple and convenient.

[0042] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
