Abstract
A coaxial loudspeaker includes a cone of a woofer; a waveguide of a tweeter, located at a front end towards the outside/large profile of the cone; and a first cavity. The first cavity includes a resonator and a cavity formed in the cone, and the resonator communicates with the cavity at the large profile of the cone. A side opposite to a position where the resonator communicates with the cavity is constructed as an orifice plate. The orifice plate is adjacent to the resonator and an orifice portion of the orifice plate communicates with the resonator.

A coaxial loudspeaker, comprising:
- a cone of a woofer;
- a waveguide of a tweeter, the waveguide being located at a front end of the cone towards an outer profile of the cone;
- and
- a first cavity, the first cavity comprising:
- a resonator and a woofer cavity formed in the cone of the woofer, the resonator communicating with the woofer cavity at the outer profile of the cone,
- wherein a side opposite to a position where the resonator communicates with the woofer cavity is constructed as an orifice plate, the orifice plate is adjacent to the resonator and an orifice portion of the orifice plate communicates with the resonator, and
- wherein the orifice plate is spaced apart from the waveguide of the tweeter by at least a portion of an outer wall of the coaxial loudspeaker that extends between the waveguide of the tweeter and the orifice plate.
A coaxial loudspeaker, comprising:
- a cone of a woofer;
- a waveguide of a tweeter, the waveguide being located at a front end of the cone towards an outer profile of the cone;
- a first cavity, the first cavity comprising:
- a resonator and a cavity formed in the cone, the resonator communicating with the cavity at the outer profile of the cone, wherein a side opposite to a position where the resonator communicates with the cavity is constructed as an orifice plate, the orifice plate is adjacent to the resonator and an orifice portion of the orifice plate communicates with the resonator;
- and
- a first outer wall surrounding the waveguide and arranged at a periphery of an outer side of the outer profile, the first outer wall being connected to the outer profile and the first outer wall connected to a second outer wall via the orifice,
- wherein the second outer wall is located on a peripheral wall surface of the waveguide,
- wherein the resonator is located between the first outer wall and the second outer wall, and
- wherein an inner wall of the cone is opposite to the second outer wall to form a channel for communicating.
A coaxial loudspeaker, comprising:
- a woofer including a cone;
- a tweeter including a waveguide;
- a first outer wall connected to the cone of the woofer;
- a second outer wall extending within a region located between the first outer wall and the waveguide of the tweeter;
- and
- an orifice plate connecting the first outer wall and the second outer wall;
- wherein a resonator is formed between the first outer wall and the second outer wall, wherein the resonator is bounded by the orifice plate, and wherein the second outer wall separates the resonator from the waveguide of the tweeter.
