Abstract: A speaker includes a basket and a diaphragm assembly. The diaphragm assembly is located on the basket, and has a diaphragm, a damper, a surround, and a conductor. An inner edge and an outer edge of the damper are respectively connected to a bottom surface of the diaphragm and the basket. The surround and the damper are disposed on the basket and at different horizontal levels. The conductor is located on a bottom surface of the damper. The diaphragm assembly can be pre-manufactured to improve the convenience of assembling the speaker. Moreover, the damper does not move up and down exceedingly along with the voice coil, thereby preventing the damper from contacting underlying components. In addition, the total thickness of the speaker can be reduced, which facilitates thinning requirements. Alternatively, an excursion length can be increased, which facilitates the low frequency design of the speaker.

Abstract: A symmetric dual suspension speaker structure is herein disclosed, comprising a basin frame, a U-shaped iron, a magnet permeability ferrite ring, a corrugated rim, a diaphragm, a sound coil, a damper clamped between the magnet permeability ferrite ring and the U-shaped iron, as well as a magnet, wherein the peripheral edge around the upper surface of the diaphragm can be stretched in the vertical direction to form a barrel component, and the corrugated rim is used to bond and fix the top end of the barrel component while the damper is used to bond and fix the bottom end of the barrel component, such that the sound coil can bring the barrel component of the diaphragm to vertically vibrate thus improving the instability existing in the bonding of the conventional diaphragm and the coil framework.
