Abstract: Provided is a speaker, including: a connector and a magnetic circuit unit and a vibration system that are fixed to the connector. The vibration system includes a first diaphragm fixed to the connector and a voice coil driving the first diaphragm to vibrate and sound. The magnetic circuit unit includes a magnet assembly providing driving force to the voice coil and a mounting member fixing the magnet assembly. A bending portion is formed by bending from an edge of the mounting member toward the first diaphragm, and the bending portion is fixedly connected to the connector. With this structure, the first diaphragm is fixedly connected to the mounting member, so as to strengthen the overall strength of the speaker and prevent the deformation of the speaker in its vibrating direction, thereby improving the quality of the speaker.

Abstract: Provided is a speaker, including: a frame, a first diaphragm and a flexible printed circuit board connected to the frame. The first diaphragm includes a first surface close to the flexible printed circuit board and arranged opposite to the flexible printed circuit board. The first surface is recessed along a direction departing from the flexible printed circuit board to form a glue slot. The first surface is connected to the flexible printed circuit board by glue to enable the glue to enter the glue slot. A thickness of the glue at a glue junction is increased to enhance strength of connection between the flexible printed circuit board and the first diaphragm to ensure reliability of mounting of the flexible printed circuit board on the first diaphragm, which may reduce a failure rate of the speaker.

Abstract: Provided is a vibration system, a sounding device and an electronic device. The vibration system includes a voice membrane, a voice coil configured to drive the voice membrane to vibrate, and a holder having a pad. The voice membrane includes a dome and a first diaphragm arranged around the dome. The dome and the first diaphragm are fixed to the holder. The voice coil is connected to the pad through a lead wire. The dome includes a first end close to the pad and a second end away from the pad and opposite to the first end. The second end has a positioning portion. The holder has a sink configured to receive the positioning portion. The dome is positioned with the holder through engagement of the sink with the positioning portion. Good symmetry of assembly is provided between the holder and the dome in the related art.

Abstract: A sound generator is provided by the present disclosure. The sound generator includes a frame; a magnetic circuit system fixed by the frame; and a vibration system carried by the frame. The vibration system includes a diaphragm and a voice coil fixed below the diaphragm for driving the diaphragm to vibrate. The voice coil includes a pair of parallel long axis edges, a pair of parallel short axis edges connected with ends of the long axis edges. The diaphragm includes a through hole formed corresponding to the long shaft edge of the voice coil, and a glue part filled in the through hole for connecting the long shaft edge of the voice coil with the diaphragm.

Abstract: A micro-speaker includes a vibration unit including a diaphragm assembly and a voice coil assembly, a magnetic circuit unit including a yoke including a voice coil bobbin and a voice coil affixed to the voice coil bobbin, and a magnet provided on the yoke, and a holder including a holder bottom wall abutting against the yoke, a holder sidewall extending from a side of the holder bottom wall close to the magnet along a direction facing away from the yoke and forming a magnetic gap with the magnet in which the voice coil is disposed, and a magnetism shielding wall formed by extending from a side of the holder sidewall facing away from the yoke while being bent towards the voice coil, a side of the magnetism shielding wall facing away from the diaphragm being provided with a hollow annular magnetic conductive sheet spaced apart from the voice coil.
