[0002] A speaker is an electroacoustic transducer that converts electrical signals into sound signals. It is widely used in electronic devices that play sound, such as speakers and headphones. In order to meet consumers' demand for aesthetics, existing electronic devices that play sound are designed to be teardrop-shaped. However, only the outer shell of such teardrop-shaped devices is teardrop-shaped, and the speaker inside is still round. This design wastes space inside the device and is not conducive to reducing the size of the device. In addition, the diaphragm of existing speakers is usually fixed to the speaker bracket by gluing. This fixing method requires a certain amount of time to wait for the glue to dry, which affects production efficiency. Moreover, when the speaker needs to be replaced and repaired, the gluing fixation will make the diaphragm difficult to remove, thereby reducing the efficiency of repair. Summary of the Invention
