Detailed Description

The present invention will be described with reference to the accompanying drawings and the detailed description, and it should be noted that, in the following description, various embodiments or technical features may be arbitrarily combined to form a new embodiment without conflict.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "horizontal", "vertical", "top", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention.

In the description of the present invention, it should be noted that unless otherwise explicitly stated or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as being fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; either directly or indirectly through intervening media, or through both elements. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

The implementation mode is as follows:

as shown in fig. 1-2, the present invention shows a passive radiator, which is installed on a mounting hole of a cabinet housing for adjusting the tone of a cabinet. In order to exert the effect of passive radiator, install it on transparent audio amplifier casing and internally mounted have the audio amplifier of luminous body (like LED light), make it can be along with audio amplifier resonance to make it dazzle along with the music sound is luminous, produce light and show, and promote tone quality through the balancing weight, satisfy user's individual need. However, the passive radiator mounted on the sound box with the transparent sound box shell and the light emitting body (such as LED light) mounted inside is opaque, so that the overall light effect of the sound box is poor and cannot meet the user's requirements.

In this embodiment, the passive radiator includes a support 1, a diaphragm 2, and a weight 3, the support 1 is transparent and is connected to the diaphragm 2, the diaphragm 2 is transparent and has a hollow accommodating portion 20, and the weight 3 is transparent and is disposed in the accommodating portion 20. That is, all parts of the passive radiator are transparent, so that the passive radiator is arranged on the transparent sound box shell and the sound box with the luminous body (such as LED light) arranged inside can improve the whole light effect of the sound box, and the requirements of users are met. Meanwhile, the sound box provided by the utility model adopts the passive radiator, so that the effect of generating light brightness by the light inside the sound box is greatly improved.

In this embodiment, the weight member 3 is made of transparent glass, or diamond, or transparent marble, because glass has the advantages of high transparency, good light-oxygen aging resistance, flame retardance and the like, and meanwhile, the transparent glass, the transparent diamond and the transparent marble have higher density, so that the weight requirement can be met, and meanwhile, the vibration quality can be adjusted by changing the thickness, so that the acoustic performance of the sound box is optimal. Of course, in other embodiments, the weight member 3 may be made of other transparent materials, as long as the weight member 3 is transparent and can reach the preset weight, and therefore, it should also fall into the protection scope of the present invention for those skilled in the art to reasonably change the transparent material of the weight member 3.

In this embodiment, the bracket 1 is made of a transparent PC material, which has a long service life in the application process due to its transparency, heat resistance, impact strength and dimensional stability. Of course, in other embodiments, the bracket 1 may be made of other transparent plastic materials, which is not limited herein.

In this embodiment, the support 1 and the diaphragm 2 are integrally formed, that is, the support 1 and the diaphragm 2 are connected into a whole by using the encapsulation vulcanization process, so that the manufacturing cost is low and the quality is good. Furthermore, the support 1, the vibrating diaphragm 2 and the counterweight 3 are integrally formed, namely the passive radiator is formed by integrally forming all parts of the passive radiator, all parts of the passive radiator are connected into a whole by using a rubber coating and vulcanizing process, and compared with the traditional adhesive bonding process (bonding by two processes of a bonding glue and a reinforcing glue), the integrated forming bonding process has the advantages of simple process, automatic production, production efficiency improvement, firm bonding, difficulty in opening and the like. It should be noted that, the bracket 1, the diaphragm 2 and the weight member 3 of the present invention are molded into a whole by encapsulation and vulcanization, which is the prior art and will not be described herein.

In addition, because between the weight part 3 and the vibrating diaphragm 2 is integrally formed through the process of rubber coating vulcanization, a through groove 30 penetrating through the upper surface and the lower surface of the weight part 3 is formed on the weight part 3, and liquid silica gel used in the rubber coating vulcanization process can be filled into the through groove 30 so as to enhance the bonding force between the weight part 3 and the vibrating diaphragm 2. Similarly, because the support 1 and the vibrating diaphragm 2 are integrally formed through the encapsulation vulcanization process, a concave part 10 is formed at the joint of the support 1 and the vibrating diaphragm 2, and liquid silica gel used in the encapsulation vulcanization process can be filled in the concave part 10, so that the bonding force between the support 1 and the vibrating diaphragm 2 is enhanced, and the service life of the passive radiator is prolonged.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are within the protection scope of the present invention.
