Abstract
A speaker structure having a simple configuration while maintaining good sound quality is disclosed. The speaker structure comprises a first speaker (20) having a first vibration plate (21), a first frame (22) for fixing the perimeter of the first vibration plate and a first magnetic circuit (24) for converting a signal into the vibration of the first vibration plate, a second speaker (30) having a second vibration plate (31), a second frame (32) for fixing the perimeter of the second vibration plate and a second magnetic circuit (34) for converting a signal into the vibration of the second vibration plate, and a fixing unit (50) for fixing the first magnetic circuit and the second magnetic circuit at their backs.
Claims12
A speaker structure comprising:
- a first speaker having a first vibration plate, a first frame for fixing the perimeter of said first vibration plate and a first magnetic circuit for converting a signal to the vibration of the first vibration plate;
- a second speaker having a second vibration plate, a second frame for fixing the perimeter of the second vibration plate and a second magnetic circuit for converting a signal to said vibration of the second vibration plate;
- a fixing unit for fixing said first magnetic circuit and said second magnetic circuit at their backs;
- a cabinet for covering said first and second speakers;
- a supporting means for supporting said fixing unit;
- and
- a shock absorber placed between said first frame and said cabinet, between said second frame and said cabinet, and between said supporting means and said cabinet,
- wherein said cabinet is kept in a floating state compared to said first and second speakers and said supporting means.
A speaker structure comprising:
- a first speaker having a first vibration plate, a first frame for fixing the perimeter of said first vibration plate and a first magnetic circuit for converting a signal to the vibration of the first vibration plate;
- a second speaker having a second vibration plate, a second frame for fixing the perimeter of the second vibration plate and a second magnetic circuit for converting a signal to said vibration of the second vibration plate;
- a fixing unit for fixing said first magnetic circuit and said second magnetic circuit at their backs;
- wherein said fixing unit has a first rib fixed at the back of said first magnetic circuit, a second rib fixed at the back of said second magnetic circuit, and a connecting unit for connecting said first and second ribs.
A speaker structure comprising:
- a plurality of speaker pairs, wherein one or more of said speaker pairs comprises,
- a first speaker having a first vibration plate, a first frame for fixing the perimeter of said first vibration plate and a first magnetic circuit for converting a signal to the vibration of the first vibration plate;
- a second speaker having a second vibration plate, a second frame for fixing the perimeter of the second vibration plate and a second magnetic circuit for converting a signal to said vibration of the second vibration plate;
- a fixing unit for fixing said first magnetic circuit and said second magnetic circuit at their backs;
- a cabinet for covering said first and second speakers;
- a supporting means for supporting said fixing unit;
- and
- a shock absorber placed between said first frame and said cabinet, between said second frame and said cabinet, and between said supporting means and said cabinet,
- wherein said cabinet is kept in a floating state compared to said first and second speakers and said supporting means.
A speaker structure comprising:
- a plurality of speaker pairs, wherein one or more of said speaker pairs comprises,
- a first speaker having a first vibration plate, a first frame for fixing the perimeter of said first vibration plate and a first magnetic circuit for converting a signal to the vibration of the first vibration plate;
- a second speaker having a second vibration plate, a second frame for fixing the perimeter of the second vibration plate and a second magnetic circuit for converting a signal to said vibration of the second vibration plate;
- a fixing unit for fixing said first magnetic circuit and said second magnetic circuit at their backs;
- wherein said fixing unit has a first rib fixed at the back of said first magnetic circuit, a second rib fixed at the back of said second magnetic circuit, and a connecting unit for connecting said first and second ribs.
