A one-piece horn device

Abstract

This utility model relates to the field of horn devices, and more specifically, to a one-piece molded horn device, including a horn and a matching lower support bracket. A wiring component is provided between the horn and the lower support bracket. At least three reinforcing ribs are evenly distributed circumferentially on the outer surface of the horn's horn-shaped curved surface, and each reinforcing rib has a threaded hole. The lower support bracket has through holes corresponding to the positions of the reinforcing ribs, and a screw passes through the through hole and is threadedly connected to the threaded hole to fix the horn and the lower support bracket. The horn and the lower support bracket are both integrally molded. This utility model, by only providing a horn and a lower support bracket, and connecting the horn and the lower support bracket by a screw, effectively eliminates the difficulty of installing multiple components and eliminates the need for glass glue or other adhesives.

Description

Technical Field

[0001] This utility model relates to the field of loudspeaker devices, and more specifically, to a one-piece molded loudspeaker device. Background Technology

[0002] As a common electroacoustic conversion device, a loudspeaker typically comprises a magnetic circuit system, a vibration system, and a support structure. In traditional loudspeaker designs, components such as magnets, washer, voice coils, diaphragms, and frames are often manufactured separately and then bonded together using silicone sealant or other adhesives. For example, in the prior art, such as the multi-voice coil loudspeaker disclosed in Chinese Patent CN206948603U, the horn and magnet fixing parts, frame, diaphragm, and other components are generally assembled using a special plastic adhesive.

[0003] Its shortcomings lie in the significant defects of this type of plastic-specific adhesive assembly: firstly, alignment of components during the bonding process is difficult, making it hard to guarantee assembly precision and affecting the consistency and acoustic performance of the speaker; secondly, during long-term use, due to temperature changes, mechanical vibration, or aging of the adhesive, the bonded areas are prone to cracking or detachment, leading to structural instability, sound quality degradation, or even component damage, seriously affecting the reliability and lifespan of the product. Utility Model Content

[0004] To address the aforementioned issues, this invention provides an integrated horn device that offers a more robust structure, is easier to assemble, and avoids reliance on adhesive bonding for fixation.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an integrally molded horn device, characterized in that it includes a horn and a lower support bracket that cooperates with it, and a wiring component is provided between the horn and the lower support bracket; The outer surface of the horn's trumpet-shaped curved surface has at least three reinforcing ribs evenly distributed circumferentially, and each reinforcing rib has a threaded hole; the lower support bracket has through holes corresponding to the positions of the reinforcing ribs, and a screw passes through the through holes and is threadedly connected to the threaded holes to fix the horn to the lower support bracket. The horn and the lower support bracket are both made in one piece.

[0006] Preferably, the lower support bracket includes, from top to bottom, a first cavity, a second cavity, and a third cavity that are connected to each other; The wiring component includes an annular sidewall, an annular bottom surface, and two wiring terminals extending outward from the annular bottom surface and protruding from the first cavity, thereby forming a fourth cavity inside the wiring component; the wiring component is entirely housed within the first cavity, and is installed with the annular bottom surface facing upward and the annular sidewall facing downward; The first cavity is located in the space above the annular bottom surface to accommodate the coil connected to the terminal block; the fourth cavity and the second cavity together form a combined chamber for accommodating the magnet; the third cavity is a tubular structure that runs vertically through the magnet for heat dissipation.

[0007] More preferably, the lower support bracket is provided with two lead wire grooves at the positions corresponding to the protrusion of the wiring terminals. This invention effectively eliminates the difficulties of installing multiple components by simply setting up a horn and a lower support bracket, with the horn and the lower support bracket connected by a screw, and also eliminates the need for the use of glass glue or other adhesives.

[0009] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0010] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model, and are not intended to indicate or explicitly suggest that the weighing or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0011] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or explicitly suggesting relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, unless otherwise explicitly specified.

[0012] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0013] For details, see Figures 1-6 A one-piece molded horn device includes a horn 1 and a lower support bracket 2 that cooperates with it, and a wiring component 3 is provided between the horn 1 and the lower support bracket 2. At least three reinforcing ribs 101 are evenly distributed circumferentially on the outer surface of the trumpet-shaped curved surface of the horn 1, and each reinforcing rib 101 is provided with a threaded hole; the lower support bracket 2 is provided with a 201 corresponding to the position of the reinforcing rib 101, and a screw passes through the 201 and is threadedly connected to the threaded hole to fix the horn 1 and the lower support bracket 2. Horn 1 and lower support bracket 2 are made in one piece.

[0014] Specifically, the lower support bracket 2 includes, from top to bottom, a first cavity 202, a second cavity 203, and a third cavity 204 that are connected to each other; The wiring component 3 includes an annular sidewall 301, an annular bottom surface 302, and two wiring terminals 303 extending outward from the annular bottom surface 302 and protruding from the first cavity portion 202, thereby forming a fourth cavity 304 inside the wiring component 3; the wiring component 3 is entirely housed in the first cavity portion 202, and is installed with the annular bottom surface 302 facing upward and the annular sidewall 301 facing downward; The space above the annular bottom surface 302 of the first cavity 202 is used to accommodate the coil connected to the terminal 303; the fourth cavity 304 and the second cavity 203 together form a combined chamber for accommodating the magnet; the third cavity 204 is a tubular structure that runs vertically through the magnet and is used to dissipate heat from the magnet.
