Audio output device and video/audio output device using the same
An audio output device including a casing, a first speaker component, a second speaker component and a sound-guiding board, and a video/audio output device using the same are disclosed. The first speaker component is a circular speaker, and is disposed at the casing. The first speaker component faces towards a first direction. The second speaker component is disposed at the casing, and faces towards a second direction which is different from the first direction. The sound-guiding board is a square plate body, located above the first speaker component, and is separated at a predetermined distance from the first speaker component.
1. An audio output device, for being covered under and separated from a board by a distance, comprising:
a casing having a first surface, a second surface and a third surface, the first surface and the third surface being opposite to each other, the second surface being connected between the first surface and the third surface;
a first speaker component disposed at or nearby the first surface of the casing and facing along a first direction; and
a second speaker component fastened to the casing such that the second speaker component is level with or parallel to the second surface, the second speaker component facing along a second direction different from the first direction, and a volume of the first speaker component being greater than a volume of the second speaker component;
wherein the board covers the first speaker component, an opening exists between the board and the casing, the second speaker component being located beside a shorter edge of the opening, the opening faces toward the second direction, an area of the first surface is larger than an area of the second surface, the first speaker component is for producing a sound wave, and a portion of the sound wave produced by the first speaker component is reflected by the board to travel along the second direction.
2. The audio output device according to claim 1 , wherein the distance is greater than or equal to the maximum stroke of the first speaker component.
3. The audio output device according to claim 1 , wherein the first speaker component is a circular speaker, the board is a square plate body.
4. The audio output device according to claim 1 , wherein the first direction is perpendicular to the second direction.
5. The audio output device according to claim 1 , wherein a recess is formed inward from the first surface and has the opening located at the second surface, the first speaker component is located inside the recess, the board covers the recess, and the second speaker component is located at the second surface.
6. A video/audio output device, comprising:
a main body having a first side and a second side opposite to each other;
a display screen located at the first side;
a board; and
an audio output device, covered under and separated from the board by a distance, comprising:
a casing having a first surface, a second surface and a third surface, the first surface and the third surface being opposite to each other, the second surface being connected between the first surface and the third surface, the casing being disposed at the main body, and the third surface facing the second side;
a first speaker component, disposed at or nearby the first surface of the casing and the first speaker component facing along a first direction; and
a second speaker component, fastened to the casing such that the second speaker component is level with or paralleled to the second surface, the second speaker component facing along a second direction different from the first direction, and a volume of the first speaker component being greater than a volume of the second speaker component;
wherein the board covers the first speaker component, an opening exists between the board and the casing, the second speaker component being located beside a shorter edge of the opening, the opening faces toward the second direction, an area of the first surface is larger than an area of the second surface, the first speaker component is for producing a sound wave and a portion of the sound wave produced by the first speaker component is reflected by the board to travel along the second direction.
7. The video/audio output device according to claim 6 , wherein the distance is greater than or equal to the maximum stroke of the first speaker component.
8. The video/audio output device according to claim 6 , wherein the first direction is perpendicular to the second direction.
9. The video/audio output device according to claim 6 , wherein a recess is formed inward from the first surface and has the opening formed on the second surface, the first speaker component is located inside the recess, the board covers the recess, and the second speaker component is located on the second surface.
