Abstract

The invention discloses a loudspeaker with multiple cover bodies. The loudspeaker comprises a sound production body, a first cover body matched with the sound production body, and a second cover body, wherein the second cover body is arranged outside the first cover body, the first cover body is provided with a hole communicated with the second cover body, a vibrating diaphragm is arranged on the hole, the taper of the first cover body is same as that of the second cover body, and the first cover body is longer than the second cover body. The strength of acoustic wave between the first cover body and the second cover body is lower than that of acoustic wave in the first cover body, and because the transmission distance of the acoustic wave is short, listening of this part of audiences is not influenced. Therefore, the volumes listened by distal and proximal audiences are almost within a certain range. The strength of acoustic wave entering the area between the first cover body and the second cover body can be adjusted by adjusting the position of a baffle.

Description

technical field [0001] The invention relates to the technical field of broadcasting, in particular to a loudspeaker for a broadcasting terminal. Background technique [0002] As the terminal of the broadcasting system, the loudspeaker is mainly used to deliver audio models to the audience. Especially for loudspeakers installed outdoors, in order to transmit audio signals to as far away as possible listeners, the loudspeakers are generally provided with a conical cover. But this also brings some problems, that is, listeners who are close to the speaker may find it harsh, but listeners who are far away from the speaker will feel that the sound is too light. Contents of the invention [0003] The invention aims at the deficiency in the prior art, and provides a speaker with a multi-layer cover body, which can make the sound heard by listeners within a certain distance be similar. [0004] In order to solve the above-mentioned technical problems, the present invention solves...
