Assignee: XMEMS LABS, INC.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC H | IPC H

Claim 29:
30. A headphone, comprising:
a first acoustic transducer configured to generate a first acoustic wave, wherein the first acoustic transducer is a MEMS (Micro Electro Mechanical Systems) fabricated speaker; and
a spreading structure comprising a body and a cover disposed on the body;
wherein the spreading structure is disposed over the first acoustic transducer and configured to guide the first acoustic wave to propagate through a sound passage formed within the spreading structure;
wherein a directionality of the first acoustic wave is spread at a sound outlet of the spreading structure after the first acoustic wave propagates through the sound passage in the spreading structure;
wherein the spreading structure further comprises a sound spreading plate, and the body is disposed within the sound spreading plate;
wherein at least one hollow part is formed within the sound spreading plate;
wherein the headphone comprises a second acoustic transducer configured to generate a second acoustic wave;
wherein the sound spreading plate is disposed over the second acoustic transducer, and the second acoustic wave propagates through the at least one hollow part.
