[0022] The technical solution of this utility model will be further clearly and completely described below with reference to the accompanying drawings and through embodiments. The described embodiments are only some embodiments of this utility model. Other embodiments obtained by those skilled in the art without creative effort are all within the protection scope of this utility model.

[0023] It should be noted that if the embodiments of this utility model involve directional indication, the directional indication is only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0024] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., shall be interpreted broadly. For example, they may refer to a fixed connection, a detachable connection, or an integral part; they may refer to a mechanical connection or an electrical connection; they may refer to a direct connection or an indirect connection through an intermediate medium; they may refer to the internal connection of two components or the interaction between two components. Unless otherwise expressly limited, those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0025] like Figure 1-4 As shown, a speaker diaphragm includes a fixing part 1 fixed to the speaker. The fixing part 1 has a folded ring part 2, and the folded ring part 2 has a diaphragm body 3. The diaphragm body 3 has a mounting groove 4 on the side facing the inside of the speaker. A diaphragm tongue 5 is embedded in the mounting groove 4. During installation, the diaphragm tongue 5 can be installed and fixed simply by embedding it in the mounting groove 4, which is convenient and quick. The fixing part 1 can be fixed to the speaker by means of adhesive, snap-fit, or embedding.

[0026] The folded ring 2 is connected between the fixed part 1 and the diaphragm body 3, and is usually made of deformable materials such as silicone or rubber. The fixed part 1 is connected to the outer ring of the folded ring 2, and the diaphragm body 3 is connected to the inner ring of the folded ring 2.

[0027] like Figure 3 As shown, the mounting groove 4 has a slot 41 formed on the side of the diaphragm body 3 facing the inside of the speaker box, and the inner ring of the folded ring part 2 is fixed on the diaphragm body 3 on the outer periphery of the slot 41.

[0028] The fixing part 1, the folding ring part 2, and the diaphragm body 3 can be integrally formed.

[0029] The diaphragm tongue 5 can not only increase the structural strength of the diaphragm body 3, but also change the thickness and weight of the diaphragm body 3, thereby adjusting the resonant frequency of the diaphragm body 3 and achieving the purpose of adjusting the bass effect. Users can replace the diaphragm tongue 5 with different materials and thicknesses according to their needs to achieve resonance with specific frequency sound waves.

[0030] The diaphragm tongue 5 is arc-shaped, with its concave side facing the inside of the speaker box and its convex side facing the outside. By designing the diaphragm tongue 5 as arc-shaped and having its concave side facing the inside of the speaker box, and in conjunction with the mounting groove 4, it can better collect sound wave energy and make the sound more directional. The shape of the mounting groove 4 is adapted to the shape of the diaphragm tongue 5. The convex side and sidewall of the diaphragm tongue 5 are attached to the inner wall of the mounting groove 4. Through the cooperation between the mounting groove 4 and the diaphragm tongue 5, the diaphragm tongue 5 can be quickly installed.

The light-shielding part 31 can be a sticker pasted on the side of the diaphragm body 3 away from the speaker, or it can be various types of inks or coatings sprayed on the side of the diaphragm body 3 away from the speaker, or it can be a shell of various materials fixed to the side of the diaphragm body 3 away from the speaker. A light-transmitting part 32 is provided on the light-shielding part 31. Both the diaphragm body 3 and the diaphragm tongue 5 can be made of light-transmitting materials (for example, the diaphragm body can be made of PET, PEN, PEI, PEEK, etc., and the diaphragm tongue 5 can be made of acrylic material). The light emitted by the lighting components inside the speaker can pass through the diaphragm body 3, the diaphragm tongue 5 and the light-transmitting part 32 to reach the outside, so that the speaker has a lighting effect.

[0032] like Figure 4 As shown, the light-transmitting part 32 can be a groove that passes through the light-shielding part 31; the light-transmitting part 32 can also be protruding from the diaphragm body 3, the light-transmitting part 32 is made of transparent material, and the light-transmitting part 32 protrudes outward through the light-shielding part 31; the light-transmitting part 32 and the diaphragm body 3 can be integrally formed.

[0033] The shape of the light-transmitting part 32 can be various decorative texts, patterns, etc.

[0034] Both the diaphragm body 3 and the diaphragm tongue 5 are elliptical.

[0035] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model.
