[0021] The following describes the embodiments of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0022] It should be noted that the structures illustrated in the drawings of this specification are only used to match the contents disclosed in the specification so that people familiar with this technology can understand and read them. They are not used to limit the conditions under which the present invention can be implemented. Therefore, they have no substantive technical significance. Any modification or adjustment of the structure should still fall within the scope of the technical contents disclosed in the present invention without affecting the effects and purposes that can be achieved by the present invention.

[0023] like Figure 2As shown, a sound membrane includes a fixed portion 21, a vibration portion 22, and an extension portion 24 extending and bent outward from the outer side of the vibration portion 22, the upper end surface of the extension portion 24 is connected to the fixed portion 21, and the lower end of the extension portion 24 is used to connect to the voice coil 3.

[0024] like Figures 1 to 3 As shown, a speaker comprises a housing 1, wherein the housing 1 is provided with a receiving groove 11, wherein the receiving groove 11 is provided with a sound diaphragm 2 and a voice coil 3, wherein the sound diaphragm 2 comprises a fixing portion 21 and a vibration portion 22 arranged at the bottom of the fixing portion 21, wherein the fixing portion 21 is arranged at the top of the receiving groove 11, wherein the fixing portion 21 is provided with a through hole 12 for exposing the vibration portion 22; wherein an extension portion 24 is provided on the outer side of the vibration portion 22 and is bent outwardly, wherein the upper end surface of the extension portion 24 is connected to the fixing portion 21, and the lower end surface of the extension portion 24 is connected to the voice coil 3. During installation, the voice coil 3 is located directly below the extension portion 24 and the width of the voice coil 3 is smaller than the width of the sound diaphragm 2.

[0025] Specifically, a sound diaphragm and a speaker provided with the sound diaphragm of the present embodiment, by dividing the sound diaphragm 2 into a fixed portion 21 and a vibrating portion 22, by extending and bending the outer side of the fixed portion 21 outward to form an extension portion 24, and the extension portion 24 makes way for the magnet 5 below, so that the present invention can be equipped with a larger magnet, thereby improving the overall sound effect of the present invention.
