Description

Echo wall sound equipment Technical Field The present invention relates to the field of whispering gallery speakers, and in particular, to a whispering gallery speaker. Background The existing whispering gallery sound is usually matched with a bass sound for use, and the whispering gallery sound is rarely integrated with a bass loudspeaker. Even if the woofer is integrated on the whispering gallery sound, the woofer is usually arranged forwards, and the caliber of the woofer is generally larger, so that the length of the whispering gallery sound is increased, the transportation is not facilitated, and the daily placement is not convenient. Disclosure of Invention The invention mainly aims to provide a whispering gallery sound, which aims to realize compact arrangement of loudspeakers in the whispering gallery sound and shorten the length of the whispering gallery sound. In order to achieve the above object, the whispering gallery speaker according to the present invention includes: the shell is provided with a containing cavity; At least one first horn arranged in the cavity, the main shaft of the first horn facing the front side of the housing, and The second loudspeaker is arranged in the containing cavity, and the sound radiation main shaft of the second loudspeaker faces the upper side of the shell; the frequency response range of the first loudspeaker covers the full audio frequency section, and the frequency response range of the second loudspeaker at least covers the bass audio frequency section. In an embodiment, the whispering gallery speaker includes two first horns, and the two first horns are disposed at intervals along the length direction of the housing. In an embodiment, the whispering gallery stereo further includes an electronic control module, and the electronic control module is disposed in the cavity. In one embodiment, the electronic control module is centered in the length direction of the housing. In an embodiment, the two first horns are respectively disposed at two sides of the electronic control module, and the first horns are disposed obliquely toward one side far away from the electronic control module. In an embodiment, the whispering gallery speaker includes two second horns, and the two second horns are disposed on two sides of the electronic control module along a length direction of the housing. In an embodiment, the second horn is disposed between the electronic control module and the first horn. In one embodiment, the whispering gallery speaker further includes a phase inversion pipe having an opening toward the front side of the housing, and a pipe body thereof extends to a space behind the first horn. In one embodiment, the casing is provided with a through hole communicated with the cavity, and the opening end of the phase inversion tube is arranged corresponding to the through hole. In an embodiment, the inverter tube is bent and includes a first section and a second section in smooth transition, the first section extends from the through hole backwards, and the second section extends from the tail end of the first section towards the rear side of the first horn. In one embodiment, the housing comprises: A top shell with a first fixing part at the front side and a second fixing part at the upper side, wherein the first horn is fixed on the first fixing part and the second horn is fixed on the second fixing part, and The bottom shell is connected with the top shell and jointly encloses to form the containing cavity, and the bottom shell provides support for the first loudspeaker and the second loudspeaker. In an embodiment, the first fixing portion and the second fixing portion are holes or mounting structures for embedding or fixing the speaker frame. According to the technical scheme, the first loudspeaker which emits full-frequency sound is arranged towards the front side of the shell, the second loudspeaker which emits middle-low frequency sound is arranged towards the upper side of the shell, so that the frames of the first loudspeaker and the second loudspeaker are arranged in a staggered mode, the voice coil and other structures of the first loudspeaker can be arranged at the bottom of the second loudspeaker frame in a borrowed mode, the voice coil and magnetic circuit and other structures of the second loudspeaker can be arranged at the bottom of the first loudspeaker frame in a borrowed mode, the installation space required by the first loudspeaker and the second loudspeaker can be overlapped, the layout of the containing cavity of the shell is compact, and the situation that the acoustic length of an echo wall is overlong and the transportation cost is increased due to the fact that the first loudspeaker and the second loudspeaker are arranged towards the same side of the shell is avoided.
