Abstract:
A micro speaker includes a planar diaphragm, spacers respectively disposed at one side surface of the planar diaphragm, an upper plate and a lower plate, one or more magnets and a circuit board. The planar diaphragm includes a vibrating diaphragm and a coil conductor. The coil conductor is stretched and bonded onto the vibrating diaphragm via an adhesive layer on the upper side surface of the planar diaphragm; the coil conductor is electrically connected to the circuit board. The speaker in this present invention can get a diameter of 15 mm or less, and a height is 5 mm or less.

Claim (Index 8):
A micro planar speaker, comprising:\n a planar diaphragm with an upper side surface and an opposite lower side surface; an upper spacer and a lower spacer respectively disposed at the upper side surface and the lower side surface of the planar diaphragm, and each defining a cavity so as to form a magnetic gap at the corresponding side surface of the planar diaphragm; an upper plate and a lower plate respectively disposed on top of the upper spacer and below the lower spacer; one or more magnets; a circuit board; and a magnet support; wherein the planar diaphragm comprises a vibrating diaphragm and one or more coil conductors; one coil conductor is stretched and bonded onto the vibrating diaphragm via an adhesive layer on one side surface of the planar diaphragm; opposite ends of the coil conductor respectively form a positive electrode and a negative electrode to electrically connect with the circuit board; the upper and lower plates are made of magnetically conductive material; perforations through each plate are provided to allow air and sound waves to pass through, and are communicated with the cavity in the spacer at the same side surface of the planar diaphragm; and each plate has flat top and bottom surfaces; the magnet support defines a center cavity therethrough which is communicated with the cavity in the spacer at the same side surface of the planar diaphragm to allow air and sound waves to pass through; and the magnets are parallel arranged in the center cavity with a space therebetween and being communicated with and aligned to the perforation in the plate; the magnet support is mounted between the upper plate and the upper spacer.
