Abstract
A microphone includes a tubular case having a bottom surface, a side surface and an opened top, a substrate which is fixed so as to block an opening portion of the opened top of the case, and has an electrode portion on an upper surface thereof, and a side-surface sound hole formed in the side surface of the case.
Claims3
A microphone comprising:
- a tubular case having a bottom surface, a side surface, and an opened top;
- a substrate which is fixed so as to block an opening portion of the opened top of the tubular case, and has an electrode portion on an upper surface thereof;
- a side-surface sound hole formed in the side surface of the tubular case;
- a ring which is to be mounted on a bottom of the tubular case and has a plurality of leg portions extending in an axial direction of the tubular case;
- a microphone assembly to be mounted on the ring;
- and
- a gate ring which is to be mounted on an upper portion of the microphone assembly, and has a plurality of leg portions extending in an axial direction of the tubular case, wherein the substrate is mounted on the gate ring, and the side-surface sound hole is formed in the side surface of the tubular case and at a position where the side-surface sound hole communicates with a gap caused in the tubular case by the leg portions of the ring and the leg portions of the gate ring.
