Embodiment Construction
[0027] In this application, subwoofer, bass, midrange and treble all refer to the frequency of sound, that is, the number of times of sound wave vibration per second, the unit is Hertz, and the symbol is HZ. The subwoofer is below 40HZ, the bass is below 500HZ, the midrange is between 500HZ and 8000HZ, and the treble is above 8000HZ. Full frequency refers to a wide range of frequencies, which can cover from subwoofer to treble.
[0028] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present. The "first", "second", "third" and "fourth" mentioned in the present inventio...

The invention relates to portable mobile folding type storage battery line array sound equipment. The portable mobile folding type storage battery line array sound box comprises a first sound box, a second sound box, a third sound box, a connecting mechanism, a folding mechanism and a fastening mechanism. The first sound box and the second sound box are rotationally connected through the folding mechanism, the second sound box and the third sound box are rotationally connected through the connecting mechanism, so that the first sound box and the second sound box have a first state and a second state which can be switched, and in the first state, the first sound box, the second sound box and the third sound box are vertically stacked in sequence from top to bottom; in the second state, the first sound box and the second sound box are folded at the side part or the top part of the third sound box, and the fastening mechanism is used for fastening the first sound box and the second sound box in the second state or fastening the first sound box, the second sound box and the third sound box; during transportation, the first sound box, the second sound box and the third sound box are overlapped and fastened, so that the size of the portable mobile folding type storage battery line array sound box is reduced.
Description
technical field [0001] The invention relates to the field of sound reinforcement, in particular to a portable mobile folding storage battery line array sound system. Background technique [0002] Battery mobile audio equipment is a very widely used audio equipment. Because of its portability, it does not need 220V strong electricity, and the battery can work for several hours by itself, so it is favored by people. However, due to the low power of common battery speakers, they can only be used in square dances, store advertisements, and small personal performances. [0003] During large-scale performances, the range of sound reinforcement is relatively large, and the audio equipment required at this time is generally heavy and bulky, which is not conducive to transportation. Contents of the invention [0004] Based on this, the present application provides a portable mobile foldable battery line array speaker, which does not affect sound amplification and is convenient for...
