Abstract: An ultrathin electromagnetic vibrating device and its manufacturing method, wherein the ultrathin electromagnetic vibrating device includes: a base frame, a vibrating reed, a set of surrounds, a voice coil and a magnetic circuit system, wherein the surrounds include an upper surround and a lower surround, respectively connected with an upper surface and a lower surface of the vibrating reed to fixedly connecting the vibrating reed with a base of the base frame. Due to an application of the lower surround to form a combined action of the upper and lower surround, the vibrating reed is only able to keep vibrating up and down vertically, a first end of the voice coil is fixedly provided on the lower surface of the vibrating reed, similarly, while a stroke of the voice coil drives the vibrating reed to vibrate up and down vertically, the voice coil achieves an up-and-down vertical stroke.

Abstract: A vibrating panel device for an electromagnetic vibrator includes at least one vibrating panel device. The vibrating panel module includes a base, a vibrating panel and an upper suspension, wherein an inner edge and an outer edge of the upper suspension are respectively connected with the base and the vibrating panel, and form an integrated whole body. Furthermore, two vibrating panel modules are fixedly connected in opposite directions to form the vibrating panel device. When the voice coil drives the vibrating panel to actuate, shaking of the vibrating panels is offset due to interactions between a pair of the suspensions and a pair of the vibrating panels. As a result, the voice coil drives the vibrating panel to process vertical up-and-down stroke.

Abstract: An electromagnetic vibration device includes a vibration plate device, a voice coil assembly, a magnetic loop system, and a peripheral basin frame. One end of the peripheral basin frame is coupled to the vibration plate device, and the other end thereof is coupled to the magnetic lop system. The peripheral basin frame includes a plurality of connecting frames, wherein every two connecting frames are connected by a connecting member to form an integral peripheral basin frame. The size of the peripheral basin frame is adjusted by the distance between the connection frames or relative increase of the number of the connection frames, so that the size of the peripheral basin frame is adjustable to match with the vibration plate device of the electromagnetic vibration device. Only a mold is required to manufacture the connecting frame to form the peripheral basin frame for different sizes of electromagnetic vibration device.

Further, two vibrating panel modules are fixedly connected in opposite directions to form the vibrating panel device. By unique structures of the vibrating panel device, when the voice coil drives the vibrating panel to actuate, shaking of the vibrating panels is offset due to interactions between a pair of the suspensions and a pair of the vibrating panels, in such a manner that the voice coil drives the vibrating panel to process vertical up-and-down stroke, so as to replace a conventional damper.
