Description

Technical Field

[0001] The utility model relates to the technical field of speakers, and in particular to a uniform light guiding structure of foam for speakers. Background Art

[0002] A speaker refers to a device that can convert an audio signal into sound. Generally speaking, it means that there is a built-in power amplifier in the speaker main body box or the subwoofer box, and after the audio signal is amplified, the sound is played back by the speaker itself, making the sound louder. The speaker is the terminal of the entire audio system, and its function is to convert audio electrical energy into corresponding sound energy and radiate it into space. It is an extremely important part of the audio system and is responsible for converting the electrical signal into a sound signal for people's ears to directly listen to.

[0003] The inventor found in the actual R & D process that in the prior art, for the light guiding of speakers, glass or transparent plastic is usually used as the light transmitting carrier, and then lamp beads are installed inside the speaker. When the lamp beads emit light, it can be displayed through the light transmitting carrier; however, using glass or transparent plastic as the light transmitting carrier cannot achieve the effect of uniform light emission; at the same time, for the materials of glass or transparent plastic, mold opening is required according to the shape of the speaker, and the production cost remains high.

[0004] Therefore, it is necessary to study a new technical solution to solve the above problems. Content of the Utility Model

[0005] In view of this, in view of the deficiencies of the prior art, the main purpose of the present utility model is to provide a uniform light guiding structure of foam for speakers, which effectively solves the technical defects of uneven light guiding and high production cost in the prior art for the light transmitting structure of speakers.

[0007] The beneficial effect of the uniform light guiding structure of foam for speakers provided by the present application is that: compared with the prior art, by arranging a sheet-shaped foam on the back surface of the metal wire frame, the light source emitted by the lamp group is evenly distributed by the sheet-shaped foam and then emitted outward; with such a structure, there is no need to use glass or a light guide plate for light source guiding, thus saving the cost of mold opening for the light transmitting carrier and reducing the manufacturing cost; and the sheet-shaped foam can also be used to achieve the uniform light distribution effect, thereby enhancing the visual experience of users.

[0030] Please refer to Figures 1 to 5 , and now an explanation will be given to the foam uniform light guiding structure for a speaker provided by the embodiments of the present application. The foam uniform light guiding structure for a speaker includes: a speaker body 10.

[0031] A support frame 11 is installed on the front side of the speaker body 10, a lamp group 12 is installed on the front side of the support frame 11, a metal wire frame 13 is installed on the speaker body 10, and the metal wire frame 13 is located on the front side of the support frame 11; a plurality of light-emitting holes (not shown in the figure) penetrating through the front and rear surfaces of the metal wire frame 13 are provided, and a sheet-shaped foam 14 is press-fitted on the rear surface of the metal wire frame 13; when the lamp group 12 emits light, the light is homogenized by the sheet-shaped foam 14 and emitted from the light-emitting holes. Specifically, by providing the sheet-shaped foam 14 on the rear surface of the metal wire frame 13, the light emitted by the lamp group 12 is homogenized by the sheet-shaped foam 14 and then emitted outward; with such a structure, it is not necessary to use glass or a light guide plate for light source guiding, thereby saving the cost of mold opening for the light guide carrier and reducing the manufacturing cost; the sheet-shaped foam 14 can also be used to achieve a light homogenization effect, thereby enhancing the user's visual experience.

[0032] Preferably, the sheet-shaped foam 14 is white foam, which has a series of characteristics such as elasticity, light weight, quick pressure-sensitive fixation, easy to use, flexible bending, ultra-thin volume, and reliable performance. By setting the white sheet-shaped foam 14 with a thickness of 3 mm, 6 mm, or 12 mm, and then setting different densities such as 20 kg / m3, 25 kg / m3, 30 kg / m3, etc. according to the sheet-shaped foam 14 with different thicknesses, the sheet-shaped foam 14 can be adapted to different light guide requirements.

[0033] In some embodiments of the present application, the metal wire frame 13 is an arc-shaped metal wire frame 13 protruding from the back to the front. When the sheet-shaped foam 14 is assembled to the arc-shaped metal wire frame 13, the front surface of the sheet-shaped foam 14 fits against the back surface of the arc-shaped metal wire frame 13. During specific assembly, the sheet-shaped foam 14 is directly cut into a shape adapted to the metal wire frame 13, and then the sheet-shaped foam 14 is inserted from the rear side of the metal wire frame 13 and pushed forward, causing the sheet-shaped foam 14 to deform, so that the front surface of the sheet-shaped foam 14 fits against the back surface of the metal wire frame 13, and the assembly of the sheet-shaped foam 14 can be completed. It can be seen that using the sheet-shaped foam 14 structure, compared with the traditional method of using components such as a light guide plate or glass for light guiding, there is no need to use a mold to mold the light guiding component, which is beneficial to reducing the manufacturing cost; at the same time, the assembly method of the sheet-shaped foam 14 is simple, which is beneficial to improving the assembly efficiency.

When the metal wire frame 13 is installed on the speaker body 10, the piercing portion 114 can pierce into the sheet-shaped foam 14, so that the sheet-shaped foam 14 can obtain a more firm fixing method, and there is no need for adhesive operation, and the assembly is fast and simple.

[0036] In other embodiments of the present application, a first abutting notch 132 is formed between the rear surface of the metal grid 13 and the first plug-in protrusion 131. When the metal grid 13 is installed on the speaker body 10, the front surface of the speaker body 10 abuts against the first abutting notch 132. A first positioning column 115 is provided on the rear surface of the support frame 11. The first positioning column 115 is provided with a first positioning hole 116. The first positioning hole 116 passes through the front surface of the support frame 11 and the rear surface of the first positioning column 115.
