[0021] The present invention will be further described below with reference to the accompanying drawings. Example 1, as shown... Figure 1 As shown, a waveguide phaser of this invention includes a central phase cone 1 and several waveguide ring walls 2. The central phase cone 1 and each waveguide ring wall 2 are arranged in concentric circles, with the central phase cone 1 located at the very center. The waveguide phaser of this invention, through the concentrically arranged central phase cone 1 and waveguide ring walls 2, can effectively improve the beam characteristics and increase the efficiency of a loudspeaker.

[0022] The top of the central phase cone 1 is an upwardly convex conical structure. The inner side of each waveguide ring wall 2 is a conical surface structure with the radius gradually increasing from bottom to top, and the outer side of the waveguide ring wall 2 is a conical surface structure with the radius gradually decreasing from bottom to top, which can better form a focused reflection.

[0023] The angle between the central phase cone 1 and the horizontal plane is preferably 30-45°, the angle between the inner side of each waveguide ring wall 2 and the horizontal plane is preferably 50-80°, and the angle between the outer side of each waveguide ring wall 2 and the horizontal plane is preferably 70-90°. This results in a better beam spread width, which can better control the beam and reduce interference problems.

[0024] A connecting rib 3 is provided between the central phase cone 1 and the innermost waveguide ring wall 2. A connecting rib 3 is also provided between each adjacent waveguide ring wall 2. This not only allows the whole to be connected as one unit, which is convenient for assembly, but also ensures the relative position between the central phase cone 1 and each waveguide ring wall 2, thereby better ensuring beam control.

[0025] The outermost waveguide ring wall 2 is provided with mounting ears 4, which facilitates installation and fixation.

[0026] The waveguide ring wall 2 of this utility model preferably has three parts, namely inner waveguide ring wall 21, middle waveguide ring wall 22, and outer waveguide ring wall 23. The inner waveguide ring wall 21, middle waveguide ring wall 22, and outer waveguide ring wall 23 are arranged in sequence from the inside to the outside, which improves the overall effect.

[0027] Several sound-permeable holes 5 are formed on the central phase cone 1. By setting the sound-permeable holes 5 on the central phase cone 1, the flatness of the frequency response curve of the loudspeaker at ultra-high frequency can be improved and ultra-high frequency distortion can be reduced.

[0028] The sound-permeable hole 5 is a circular hole, and there are multiple sound-permeable holes 5. In this embodiment, there are six sound-permeable holes 5, and each sound-permeable hole 5 is located on the same circumference. By adjusting the shape and position of the sound-permeable hole 5, the sound of a specific frequency can be adjusted, thereby better improving the attenuation problem of a specific frequency caused by the blockage of the central phase cone 1.

[0029] Example 2, as Figure 2 As shown, a loudspeaker according to this utility model includes a loudspeaker body 6 and a waveguide phaser as described in Embodiment 1; the loudspeaker body includes a conical drum 61 and a bracket 62, a waveguide phaser mounting ear 4 is connected to the loudspeaker bracket 62, and the waveguide phaser is disposed above the conical drum 61; the loudspeaker of this utility model has beam control, high efficiency, and can be well used in full-range loudspeaker array speakers.
