Referring to fig. 1, 2 and 4, the wide directivity conference audio of open type according to the embodiment of the present invention includes a box 100, a plurality of speakers and two wooden box phase reversal tubes 400. The two wooden box inverter tubes 400 are symmetrically arranged on two sides of at least one loudspeaker, a first included angle of 18-20 degrees is formed between the two wooden box inverter tubes 400, and the direction of the first included angle is consistent with the sound production direction of the loudspeaker. When the loudspeaker works, a part of sound waves emitted by the vibration of the loudspeaker are directly emitted from a cone or a horn of the loudspeaker, and the sound waves outside the cone or the horn are reflected by the inner wall of the box body 100 and then are emitted from the two wooden box phase inversion tubes 400. The two wooden case inverter tubes 400 emit sound waves inside the case 100 at an angle, strengthen the sound waves at the edge of the sound wave diffusion range, and enhance the directivity at the edge of the sound wave diffusion range, so that the sound equipment has a wide directivity, a large sound diffusion range and a long sound diffusion distance, and a good sound quality can be maintained.

Referring to fig. 1, in some embodiments, baffle 110 is disposed between tweeter 200 and woofer 300, and baffle 110 divides cabinet 100 into two areas that are not in communication with each other, preventing voice coil vibration between tweeter 200 and woofer 300 from affecting each other in cabinet 100 and affecting the speakers to cause distortion.

Referring to fig. 1, in some embodiments, to ensure better broad directivity, tweeter 200 is selected as a tweeter having a horn opening angle between 91 degrees and 95 degrees. The opening angle of the cone of the woofer 300 is between 107 degrees and 111 degrees. The tweeter 200 with the above opening angle is matched with the woofer 300, so that the sound has a frequency width of 20KHz to 22 KHz.

Referring to fig. 1 to 4, an open type wide directivity conference sound according to an embodiment of the present invention will be described in detail with reference to a specific embodiment. It is to be understood that the following description is illustrative only and is not intended as a specific limitation on the invention.

Referring to fig. 1 to 4, in the present embodiment, an included angle between two wooden box inverter tubes 400 is 20 degrees, and the wooden box inverter tube 400 is a rectangular channel surrounded by an L-shaped plate and a side wall of the box 100, so that the sound volume can be saved while the sound intensity is enhanced. The horn of tweeter 200 has an opening angle of 93 degrees and the cone of woofer 300 has an opening angle of 109 degrees. Accordingly, referring to fig. 3, in the present embodiment, the left and right side walls of the box 100 are also at an angle of 20 degrees. A baffle is provided between tweeter 200 and woofer 300. In this embodiment, in order to protect the horn of the tweeter 200 and the cone of the woofer 300 from being damaged, the metal mesh 120 is provided on the front side of the cabinet 100.

According to the utility model discloses wide directive property meeting stereo set of open type, the inside sound wave of box can set up in the wooden case phase reversal pipe of high pitch loudspeaker both sides through the symmetry and send, and the sound wave intensity at reinforcing loudspeaker both sides sound wave diffusion edge makes the stereo set have broad directive property.
