Description

Technical Field

[0001] The utility model relates to the technical field of sound boxes, in particular to a multi-purpose sound box which is easy to adjust. Background Art

[0002] A speaker refers to a device that can convert audio signals into sound. In layman's terms, it refers to a speaker main box or a subwoofer box with a built-in power amplifier. The audio signal is amplified and then played back by the speaker itself to make the sound louder. The speaker is the terminal of the entire audio system, and its function is to convert audio electrical energy into corresponding sound energy and radiate it into space.

[0003] Nowadays, there are many kinds of speakers, and the functions and qualities of speakers used in different occasions are different. Among them, speakers used for outdoor performances are generally larger in size, with a pull rod on the top of the speaker, casters on the bottom of the speaker, and a woofer and a tweeter on the front of the speaker, which are used to pronounce different audio frequencies respectively. However, the existing speakers cannot adjust the speaker pronunciation position according to outdoor conditions. Because outdoor performers sometimes have a large team, but generally there is only one speaker, and because the outdoor space is open and there are many noises, the speaker pronunciation position is concentrated, then the performers close to the speaker will inevitably hear a loud sound, while the performers far away from the speaker may hear a smaller sound or be interfered by the noise, which causes different performers to have different opinions on the volume adjustment of the speaker. For this reason, we propose a multi-purpose speaker that is easy to adjust. Utility Model Content

[0004] The utility model aims to provide a multi-purpose speaker that is easy to adjust, which has the advantage of being easy to adjust the sound position of the speaker, and solves the problem that the existing speaker cannot adjust the sound position of the speaker according to outdoor conditions. Because outdoor performers sometimes have a large team, but generally only one speaker, and because the outdoor space is open and there are many noises, the sound position of the speaker is concentrated, so the sound heard by the performers close to the speaker is bound to be very loud, while the sound heard by the performers far away from the speaker may be smaller or interfered by the noise, which leads to the problem that different performers have different opinions on the volume adjustment of the speaker.

[0005] To achieve the above object, the utility model provides the following technical solution: a multi-purpose speaker that is easy to adjust, comprising:
