SPEAKER AND DIAPHRAGM THEREOF

摘要

The instant disclosure provides a speaker which includes a support structure, a diaphragm, and a coil. The upper frame of the support structure has an opening formed thereon. The diaphragm is disposed on the upper frame of the support structure and located at the peripheral portions of the opening The diaphragm has a substrate layer and a magnetic layer formed thereon. The coil is disposed on the lower frame of the support structure and opposite to the diaphragm. The coil drives the diaphragm to vibrate for sound generation by electromagnetic induction when an electrical current is introduced through the coil.

主权项

1. A speaker, comprising:
a support structure including an upper frame and a lower frame, the upper frame having portions defining an opening thereon; a diaphragm disposed on the upper frame of the support structure circumscribed by portions defining the opening, the diaphragm having a substrate layer and a magnetic layer formed on a surface of the substrate layer; and a coil disposed on the lower frame, the coil and the diaphragm arranged opposite to one another and cooperatively defining a gap there-between; wherein the coil and the diaphragm generates electromagnetic induction in response to electrical current passing through the coil such that the diaphragm vibrates for sound generation.
