Abstract
A speaker contains a pipe member containing opposed ends and a sounding body that is driven on the basis of an acoustic signal which is applied to the sounding body. The sounding body is arranged on the same axis as that of the pipe member. Sound wave radiated from the sounding body radiates from the opposed ends of the pipe member.
Claims7
A speaker, comprising:
- a disk-shaped base casing with a cylindrical opening;
- a pipe mounted on the base casing;
- a plurality of actuators mounted on the base casing and attached to the pipe;
- and
- a speaker unit installed in the cylindrical opening of the base casing,
- wherein the plurality of actuators and the pipe constitute a high frequency sounding component that acts as a tweeter, the pipe being a diaphragm to produce high frequency sound, and
- wherein the speaker unit and the pipe constitute a low frequency sounding component that acts as a woofer, the pipe being a resonator which improves the low frequency sound produced by the speaker unit.
4 more elements
A method of reproducing and outputting acoustic sound with a high frequency sounding component and a low frequency sounding component, the method comprising:
- producing the high frequency sounding component with a pipe and a plurality of actuators mounted on a base casing and attached to the pipe, the pipe being a diaphragm;
- and
- producing the low frequency sounding component with a speaker unit, the pipe being a resonator which improves the sound produced by the speaker unit.
