LOUDSPEAKER

摘要

A loudspeaker includes a base, a sound-reflecting member located at a side of the base, a sound generator mounted to the sound-reflecting member, an adjusting member including a number of magnetic pieces and located at an opposite side of the base, a connecting member connected between the sound-reflecting member and the adjusting member, a supporting member, and a controlling apparatus. The supporting member includes a number of first electromagnets mounted to the magnetic pieces. The controlling apparatus is electrically coupled to the first electromagnets. The controlling apparatus controls the first electromagnets to attract the magnetic pieces, to allow the adjusting member to swing, and the adjusting member drives the connecting member to rotate, thereby swinging the sound-reflecting member.

主权项

1. A loudspeaker, comprising:
a base; a sound-reflecting member located at a side of the base; a sound generator mounted to the sound-reflecting member; an adjusting member located at an opposite side of the base, the adjusting member comprising a plurality of magnetic pieces; a connecting member rotatably extending through the base, and connecting the sound-reflecting member and the adjusting member; a supporting member comprising a plurality of first electromagnets mounted to the plurality of magnetic pieces; and a controlling apparatus electrically coupled to the plurality of first electromagnets; wherein the controlling apparatus controls the plurality of first electromagnets to attract the plurality of magnetic pieces, to allow the adjusting member to swing, and the adjusting member drives the connecting member to rotate, thereby swinging the sound-reflecting member, to adjust an angle between the sound-reflecting member and the base.
