Detailed implementation manners

[0025] The following further describes the present application in detail with reference to the accompanying Figures 1-10 drawings.

[0026] Embodiment 1:

[0027] Referring to Figures 1 to 8 , this embodiment discloses a paper carving Bluetooth speaker, which includes a front housing 1, a rear housing 2, a speaker 3, a circuit board 4 and a rechargeable battery 5. The speaker 3, the circuit board 4 and the rechargeable battery 5 are all arranged between the front housing 1 and the rear housing 2. The speaker 3 and the rechargeable battery 5 are both electrically connected to the circuit board 4. The paper carving Bluetooth speaker further includes a paper carving assembly 6, which is arranged between the front housing 1 and the rear housing 2. The paper carving assembly 6 sequentially includes a transparent window plate 61, spaced-apart paper carving pictures 62 and a first frame partition 63, a soft light sheet 64, a second frame partition 65 and a light board 66 from outside to inside. The light board 66 is electrically connected to the circuit board 4, and at least one LED lamp 661 is provided on the light board 66. The first frame partition 63 is used to make the plurality of paper carving pictures 62 three-dimensional, and the second frame partition 65 is used to control the distance between the soft light sheet 64 and the light board 66 to obtain uniform backlight. Referring to Figure 3 and Figure 4 , the speaker 3 is a horn, which is a common sound generating unit and is extremely widely used.

[0028] In this embodiment, a plurality of positioning posts (not shown) are provided on the front housing 1. Semi-open positioning holes 621 are provided on the side edges of the paper carving picture 62, the first frame partition 63, the soft light sheet 64, the second frame partition 65, and the lamp board 66. The positioning posts are inserted into the positioning holes 621 to position the paper carving picture 62, the first frame partition 63, the soft light sheet 64, the second frame partition 65, and the lamp board 66 in the radial direction of the positioning posts, ensuring the accuracy of the paper carving pattern and preventing dislocation.

[0029] In this application, by providing the first frame partition 63, a spacing is created between the paper carving pictures 62, increasing the layering and enhancing the three-dimensional effect. Setting the paper carving assembly 6 on the Bluetooth speaker combines artistry and ornamental value, can create a good usage atmosphere, and improve the texture of the Bluetooth speaker. By providing the second frame partition 65, the soft light sheet 64 and the lamp board 66 are separated to obtain uniform backlighting. The soft light sheet 64 can specifically be made of greaseproof paper, which is non-glare and does not cause eye strain. The LED lamp 661 on the lamp board 66 is at least as few as one, with low cost and good effect.

[0030] Embodiment Two:

[0031] Referring to Figure 9 and Figure 10 , the difference from Embodiment One is that the speaker 3 is a planar diaphragm sound generating unit, and the planar diaphragm sound generating unit and the paper carving assembly 6 are arranged side by side (depending on the specific shape of the speaker, they can also be arranged vertically). Patterns can be sprayed on the surface of the planar diaphragm sound generating unit, and combined with the exquisite paper carving assembly 6, making the Bluetooth speaker no longer look like a speaker, but more like a photo frame or a work of art.

[0032] Referring to Figure 10 , the planar diaphragm sound generating unit includes an elastic diaphragm 31 made of Kevlar fiber material, a rigid diaphragm 32 made of balsa wood material, an elastic transition film 33 made of EPDM material, and a magnetic circuit assembly 34 as the excitation source. The elastic diaphragm 31 is tensioned on the front housing 1. The elastic transition film 33 is adhered to the back of the elastic diaphragm 31 with glue. The rigid diaphragm 32 is adhered to the back of the elastic transition film 33 with glue. The magnetic circuit assembly 34 is adhered to the back of the rigid diaphragm 32 with glue. Since the magnetic circuit assembly 34 is in direct contact with the rigid diaphragm 32, the directly contacted area can cause the rigid diaphragm 32 to generate high-frequency response, and the non-directly contacted area generates medium-frequency response. An elastic transition film 33 with certain flexibility is provided between the rigid diaphragm 32 and the elastic diaphragm 31, which plays a buffering role and can cause the elastic diaphragm 31 to generate ultra-low-frequency response. The planar diaphragm sound generating unit can achieve balanced configuration in high, medium, and low frequencies. The planar diaphragm sound generating unit as a whole can be made very thin, being closer to a traditional photo frame.

[0033] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
