A first distance between the outer annular portion and the inner portion at a longitudinal side of the polygonal membrane is smaller or greater than a second distance between the outer annular portion and the inner portion at a corner of the polygonal membrane.

The electrodynamic loudspeaker (10), comprising: a fixed frame (12), a motor including a fixed base (14) connected to the fixed frame (12) and a part (16) movable axially relative to the fixed base (14) along an axis (A-A), a convex membrane (18), the convexity of which is oriented toward the outside of the loudspeaker (10), and a truss (20) connecting the convex membrane (18) and the moving part (16).

The truss (20) comprises an inner ring (46) and an outer ring (48) that are coaxial, connected to one another by radial pillars (50) and a crown (52) for fastening to one end (53) of the moving part (16), the convex membrane (18) being fastened bearing on the inner and outer rings (46, 48).

A loudspeaker is disclosed. The loudspeaker includes a diaphragm with a fixed portion and a movable portion. The fixed portion is attached to the movable portion by a plurality of leaf springs disposed between the fixed portion and the movable portion of the diaphragm. A coil is disposed over the diaphragm in the movable portion of the diaphragm. A magnet assembly is operatively disposed relative to the coil, wherein upon flow of current through the coil, the movable portion of the diaphragm moves relative to the fixed portion.

The present disclosure provides a micro sound device. The micro sound device includes a basket having an accommodating space, a vibration system secured to the basket, and a magnetic circuit system accommodated in the basket and configured to drive the vibration system to vibrate and produce sound. The vibration system includes an upper diaphragm secured to the basket, a voice coil located below the upper diaphragm and configured to drive the upper diaphragm to vibrate and produce sound, and a support apparatus elastically supporting the voice coil. The support apparatus is disposed opposite to the upper diaphragm and separately from the upper diaphragm. The magnetic circuit system includes an upper clamping plate secured to the basket. One end of the support apparatus is fixed to one side of the upper clamping plate and the other end of the support apparatus is fixed to the voice coil.

The present disclosure provides a speaker which includes a frame, and a vibration system and a magnetic circuit system that are accommodated in the frame, where the magnetic circuit system is configured to drive the vibration system to vibrate and produce sound. The vibration system includes a diaphragm for vibrating and producing sound and a voice coil for driving the diaphragm to vibrate, and the magnetic circuit system includes a yoke fixedly connected to one end of the frame away from the diaphragm and a magnet assembled on the yoke. The vibration system further includes an iron core for driving the diaphragm to vibrate, and the voice coil is wound around the iron core. Compared with a related technology, the speaker provided in the present disclosure has a better acoustic effect.

A tweeter includes a magnet unit, a voice coil, a casing panel; and a vibration unit. The vibration unit includes an inverted diaphragm and a resilient suspension member. The resilient suspension member includes a suspension member body and an inner side connecting edge and an outer side connecting edge integrally extended from the suspension member body respectively, wherein when the inner side connecting edge is integrally coupled to the outer surface of the inverted diaphragm, the outer side connecting edge thereof is integrally coupled to the outer surface of the casing panel. One end of the voice coil is coupled to the inverted concave diaphragm, while the opposing end thereof is coupled with the magnet unit. The tweeter is able to provide a high-pitch voice with a high frequency of 2560 Hz or above, or even 40 kHz or above, to enhance the high-pitch sound effect of the tweeter.

A speaker structural layer includes speaker units arranged in array. At least one of the speaker units includes a first electrode, a second electrode and a diaphragm. The second electrode is opposite to the first electrode. The diaphragm is disposed between the first electrode and the second electrode.

In accordance with one aspect, a diaphragm for an acoustic receiver is provided that includes a frame, a paddle flexibly coupled to the frame, and a gap between a portion of the paddle and the frame. The diaphragm further includes siloxane material coupled to at least a portion of the paddle and to at least a portion of the frame. The siloxane material covers the gap. In another aspect, a method is provided for making an acoustic receiver diaphragm.
