Abstract
A sound absorber includes at least one cavity and at least one mouth to communicate the at least one cavity with an outside of the sound absorber. The at least one cavity includes a top surface, a bottom surface, and a side wall. The top surface includes the mouth. The bottom surface opposes the top surface. The side wall is extended to connect the top surface with the bottom surface. At least one of the top surface and the bottom surface is inclined with respect to the side wall.
Claims19
A sound absorber having at least one cavity, the sound absorber comprising:
- a top surface forming member including at least one flange projecting therefrom in a direction into or out of the at least one cavity to direct sound from a sound source of an electronic device into the cavity, at least a portion of the top surface forming member forming a top surface of the sound absorber, the at least one flange defining an opening in the top surface to communicate the at least one cavity with an outside of the sound absorber;
- a bottom surface opposing the top surface;
- and
- at least two side walls extending linearly from the bottom surface to the top surface in a cross-section perpendicular to the top surface forming member to connect the top surface with the bottom surface, wherein
- the at least two side walls are made of resin,
- the bottom surface is an exterior cover of the electronic device, and
- the top surface and the bottom surface each being inclined with respect to the at least two side walls while a distance between adjacent ones of the at least two side walls associated with a same one of the at least one cavity is same from the bottom surface to the top surface such that the at least one flange is inclined with respect to the at least two side walls.
A sound absorber having at least one cavity, the sound absorber comprising:
- a top surface forming member including at least one flange projecting therefrom in a direction into or out of the at least one cavity, at least a portion of the top surface forming member forming a top surface of the sound absorber, the at least one flange defining an opening in the top surface to communicate the at least one cavity with an outside of the sound absorber;
- a bottom surface opposing the top surface;
- and
- at least one side wall extending linearly from the bottom surface to the top surface in a cross-section perpendicular to the top surface forming member to connect the top surface with the bottom surface, wherein
- the at least one side wall is made of resin,
- at least one of the top surface and the bottom surface is inclined with respect to the at least one side wall, and
- the top surface, the bottom surface and the at least one side wall are a plurality of members that constitute the at least one cavity, the plurality of members being fastened to each other by one or more screws.
