Abstract: This application provides a speaker and an electronic device. The speaker (30) includes a housing (31), a vibration component (32), and a magnetic circuit component (33). The housing (31) has an inner cavity (311). The magnetic circuit component (33) is disposed in the inner cavity (311). The magnetic circuit component (33) has a magnetic gap (333). The vibration component (32) includes a first diaphragm (321), a second diaphragm (322), and a voice coil (323). The first diaphragm (321) and the second diaphragm (322) are respectively located on two opposite sides of the magnetic circuit component (33). Circumferential edges of the first diaphragm (321) and the second diaphragm (322) are connected to the housing (31). The voice coil (323) is located inside the magnetic gap (333), and two opposite sides of the voice coil (323) are respectively connected to the first diaphragm (321) and the second diaphragm (322). The speaker and the electronic device in this application have large loudness on a premise of miniaturization.

Abstract: Apparatus and methods for a velocity-sensing approach to loudspeaker motional feedback comprising providing a first magnetic field to couple primarily with the voice coil to drive the voice coil, providing a second magnetic field to couple primarily with the sensing winding, and sensing the voltage induced in the second, sensing winding as it reciprocates in the second magnetic field. The second magnetic field has an orientational periodicity which is circumferential in relation to the reciprocation axis and this orientational periodicity extends over at least a part of the length of the former along the reciprocation axis.

Abstract: A loudspeaker device comprises first and second diaphragms (12, 14) arranged co-axially in an opposed relation to each other to cancel mechanical vibrations. Each diaphragm has multiple voice coils, with the voice coils of the first and second diaphragms (12, 14) arranged in the same plane to reduce the height of the loudspeaker device.

Abstract: A speaker includes a diaphragm including a circular hole in which a bobbin is attached and an oval or elliptical outer peripheral end. The diaphragm includes a circular cross-sectional area in the range of a predetermined height above a base having the circular hole. The diaphragm further includes an intermediate area whose outer surface has a small curvature radius above the circular cross-sectional area and an expanded area that is oval in cross section above the intermediate area.
