Description

Technical Field

[0001] This utility model relates to the field of loudspeaker technology, and in particular to a teardrop-shaped loudspeaker. Background Technology

[0002] A loudspeaker 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. To meet consumers' aesthetic demands, existing electronic devices that play sound are designed in a teardrop shape. However, only the outer shell of such devices is teardrop-shaped; the speaker inside is still circular. This design wastes internal space and is not conducive to reducing the size of the device. Furthermore, the diaphragm of existing loudspeakers is usually fixed to the speaker bracket with adhesive. This fixing method requires a certain amount of time to allow the adhesive to dry, which affects production efficiency. Moreover, when the loudspeaker needs to be replaced or repaired, the adhesive fixation makes it difficult to disassemble the diaphragm, thus reducing repair efficiency. Utility Model Content
