Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1 to 6, the present utility model provides a technical solution: the utility model provides a portable audio amplifier's linear array speaker system, including audio amplifier main part 1, mainboard subassembly 2, main speaker subassembly 3, linear array speaker subassembly 4 and loudspeaker net 5, mainboard subassembly 2 fixed mounting is at audio amplifier main part 1 top surface, installs a plurality of interface 11 on the mainboard subassembly 2 lateral wall, and the convenience is connected with external equipment, and audio amplifier main part 1 front side is provided with main speaker subassembly 3, and main speaker subassembly 3 front side is provided with linear array speaker subassembly 4, and audio amplifier main part 1 front side wall fixedly connected with loudspeaker net 5.

Wherein, the main speaker component 3 is responsible for the bass part, and the bass has the characteristics of strong shock feeling, strong and powerful, plump and deep; bass is the part with the largest air vibration amplitude, and the air vibration can be obviously perceived by touch; the bass direction sense is weak, and the starting direction is difficult to distinguish by the human ear, so that the independent placement position of the bass loudspeaker is generally not required; however, because of the strong enough field pressure, the bass can bring the sense of motion to people.

Referring to fig. 2 and 3, two preformed holes 6 are formed in the front side wall of the sound box main body 1, the main speaker assembly 3 is installed in the preformed holes 6, and two phase inversion holes 7 are formed in the front side wall of the sound box main body 1 close to the bottom surface.

Referring to fig. 2 and 4, the linear array speaker assembly 4 includes a bracket 8, a plurality of mounting holes are formed in the bracket 8, a linear array speaker main body 9 is mounted in the mounting holes, screw holes 10 are formed in the side walls of the bracket 8 near four corners, the bracket 8 is fixedly connected to the inner cavity of the sound box main body 1 and located at the front side of the main speaker assembly 3, the linear array speaker assembly 4 is formed by linearly arranging a plurality of horns, and two horns are added in the upper and lower positions in the middle on the basis.

The linear array loudspeaker component 4 is responsible for the middle-pitched and high-pitched parts, the high-pitched part expresses the fineness of sound, the middle-pitched human voice is vivid in restoration, the tone is clean and powerful, and the rhythmicity is strong; the high-frequency loudspeaker works in a relatively sharp tone range, namely a high working frequency state, the high-frequency directivity is strong, and the rotation direction of the loudspeaker can be obviously judged by the human ear; the midrange works in a moderate tone range, and is a sound-producing loudspeaker of the main body part of the sound; the midrange is the main part of the sound information received by the human ear, and most of the distinguishable sound contents are emitted by the midrange loudspeaker; therefore, the woofer is not generally used alone, but is matched with the tweeter and the midrange to form a sound system, and the sound system emits sound with vibration and has lower frequency, so that the ears of a person are resonated and shocked.

Because of the characteristic of concentrated middle-high sound directions, the linear array loudspeaker systems of the conventional portable loudspeaker boxes are arranged on a straight line, and the problems of short transmission distance and large sound transmission attenuation are solved, but the situation that sound fields are too concentrated, so that the sound propagation angles are narrow and the sound intensities of the upper, middle and lower three points at the same position are inconsistent can also occur. Therefore, in order to solve the problem, the linear array loudspeaker system of the scheme adds the upper loudspeaker and the lower loudspeaker on the basis of the linear arrangement of the original linear array system, so that the sound field is wider, and the superdirectivity of one line is avoided.

Working principle: during the use, through the mode of arranging linear array speaker 9 according to the cross, can effectually enlarge the sound propagation scope, effectively solve the problem that the sound propagation angle is too narrow, main speaker subassembly 3 and linear array speaker subassembly 4 are connected through electric wire and mainboard subassembly 2 linearity respectively, mainboard subassembly 2 passes through the electric wire and sends electroacoustic signal, control main speaker subassembly 3 and linear array speaker subassembly 4 work, in addition, this scheme is a set of arrangement into straight line, the radiating element of interval inseparable, and have the same amplitude and phase place, through linear transmission mode, improve transmission distance, reduce the attenuation degree in the sound transmission process, adopt main speaker subassembly 3 and linear array speaker subassembly 4 cooperation to use simultaneously, can improve the sound feel greatly, accord with modern crowd's user demand more.

Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
