Abstract:
An opening portion is formed along an outer peripheral edge of a diaphragm in a second casing portion partitioned by the diaphragm. In the opening portion, a plurality of fins is arranged at regular intervals, and an air passage is formed between every adjacent two of the fins. The fin and the air passage are formed so as to be at an angle to a corresponding imaginary line that extends from the vibration center line of the diaphragm in the radial direction. By forming each of the air passages obliquely, noise generated by an air flow due to sound pressure is reduced.

Claim (Index 1):
An in-vehicle speaker comprising:\n a casing; a frame member enclosed in the casing; a diaphragm enclosed in the casing, where the frame member supports an outer peripheral portion of the diaphragm; and a magnetic drive unit configured to drive the diaphragm, wherein the inside of the casing is separated into a sound producing space and an antiphase space by the diaphragm serving as a boundary, and the casing is composed of a first casing that forms the sound producing space therein and a second casing that forms the antiphase space therein, wherein the first casing has a sound emitting port that enables the sound producing space to communicate with an interior space of a vehicle, wherein the second casing includes a lid portion located at the antiphase space side to cover the diaphragm and an opening portion that opens along a peripheral portion of the lid portion, and the opening portion enables the antiphase space to communicate with a non-interior space of the vehicle, wherein a plurality of fins is arranged at intervals in the opening portion along the peripheral portion of the lid portion, an air passage is formed between every adjacent two of the fins, and at least part of the air passage extends at an angle to an imaginary line extending from the center of the diaphragm in a radial direction.
