Abstract

The invention discloses a loudspeaker device, comprising a vibration system, a magnetic circuit system, and an auxiliary system for receiving and fixing the vibration system and the magnetic circuit system. The vibration system comprises a vibrating diaphragm. The auxiliary system comprises a front cover. A waterproof gasket is provided at one side of the front cover far away from the vibration system. The vibrating diaphragm, the front cover and the waterproof gasket are integratedly combined by injection moulding. The vibrating diaphragm of the vibration system and the front cover and the waterproof gasket of the auxiliary system are integratedly combined by injection moulding, and the waterproof gasket is compressed after being contacted with a terminal, so that the loudspeaker device of the invention satisfies the terminal waterproof requirement of IPX7 or higher, achieving good waterproof effect. Furthermore, the vibrating diaphragm, the front cover and the waterproof gasket are integratedly formed, thereby simplifying the production process of the waterproof loudspeaker device, improving the production efficiency, lowering the production cost of the loudspeaker device and increasing the yield rate of the repaired loudspeaker device.
