Abstract:
1. An electrode connection structure of a speaker unit, wherein the speaker unit comprises an electrode with a plurality of openings, a vibrating membrane, and a plurality of supporting bodies disposed between the electrode and the vibrating membrane to form a cavity space as a working region for the vibrating membrane, the vibrating membrane comprising an electret layer and a metal thin film electrode, the electrode connection structure comprising: a first conductive electrode and a second conductive electrode, both of which are electrically isolated from each other, for respectively providing sound source signals for the speaker unit to generate sounds; a first adhesive material, adhering the first conductive electrode substantially in parallel on a surface of the electrode with the plurality of openings; and a second adhesive material, adhering the second conductive electrode substantially in parallel on a surface of the metal thin film electrode of the vibrating membrane, wherein the first adhesive material comprises adhesive characteristics, so as to electrically connect the first conductive electrode to the electrode with the plurality of openings, and the first adhesive material is adhered to a side of the surface of the first electrode closely adjacent to the conductive electrode with a first certain elongated area, and wherein the second adhesive material comprises adhesive characteristics, so as to electrically connect the second conductive electrode to the metal thin film electrode of the vibrating membrane, and the second adhesive material is adhered to a side of the surface of the second electrode closely adjacent to the metal thin film electrode of the vibrating membrane with a second certain elongated area.
