Abstract:
Provided is a loudspeaker. The loudspeaker comprises a connecting member, and a magnetic circuit assembly and a vibration assembly which are fixed to the connecting member. The vibration assembly comprises a first diaphragm fixed to the connecting member and a voice coil for driving the first diaphragm to vibrate and produce sound. The magnetic circuit assembly comprises a magnetic steel assembly for providing a driving force for the voice coil, and an installation member for fixing the magnetic steel assembly. An edge of the installation member is bent towards the first diaphragm to form a bent portion, and the bent portion is fixedly connected to the connecting member. By using the structure, the first diaphragm is fixedly connected to the installation member, so that the overall strength of the loudspeaker is enhanced, deformation of the loudspeaker in the vibration direction is avoided, and the quality of the loudspeaker is thus improved.
