Abstract
The invention provides a coaxial loudspeaker dot matrix sound box, wherein coaxial loudspeaker units are combined in matrix arrangement manners of 1, A1-A2 and B1-B2 (shown in a picture 1), or 2, A1-A2-A3 and B1-B2-B3 (shown in a picture 2), or 3, A1-A2-A3-A4, B1-B2-B3-B4, or 4. A1-A2-A3-A4, B1-B2-B3-B4 and C1-C2-C3-C4. According to the matrix arrangement, a planar matrix layout is used according to different use occasions, or an included-angle matrix layout in which subsets are aligned to different directions.
Description
Technical field
The invention belongs to electroacoustic techniques and Specialty Hi-Fi technical field, relate to Professional sound box technology.
Background technology
Existing traditional specialty audio amplifier is made up of high pitch, middle pitch, bass horn unit or high pitch, bass horn unit in a casing, because senior middle school's bass is not on a point, the sound sent is looser, when closer from loudspeaker, significantly can hear that high pitch, bass send from two points, auditory localization is poor.Occurred that coaxial loudspeaker solved the problem of auditory localization afterwards, accomplished point sound source public address.And in practice, different according to occasion, some audio amplifier needs to adopt angle design to increase acoustic radiating face, some occasion then need loudspeaker to aim at different radiation directions and reach sound field around effect, and in present coaxial sound box, only have a coaxial loudspeaker unit, radiating surface is limited on the basis of loudspeaker unit radiating surface, more cannot aim at different radiation directions.
Summary of the invention
The present invention is by A1-A2, B1-B2(Fig. 1 by coaxial loudspeaker unit) or A1-A2-A3, B1-B2-B3(Fig. 2), A1-A2-A3-A4, B1-B2-B3-B4, A1-A2-A3-A4, B1-B2-B3-B4, C1-C2-C3-C4, the mode of matrix arrangement combines.The arrangement of this matrix, according to the difference of use occasion, adopts two-way array layout, or adopts the angular separation matrix layout that packet alignment is different.As: A2, B2 plane figure, the left angle of A1, B1 tilts, and the right angle of A3, B3 tilts (Fig. 3), or the left angle of A1, B1 tilts, and the right angle of A2, B2 tilts (Fig. 4).Thus increase the radiating surface of audio amplifier, each coaxial loudspeaker unit senior middle school bass is with a sounding, forming surface diffusion after combination in audio amplifier, senior middle school's bass diffusion ratio is more even, compensate for the defect that traditional specialty audio amplifier high, normal, basic speech source electricity is poor, also compensate for the problem that coaxial sound box acoustic radiating face limits.Because the impedance matching requirements of Professional sound box in Specialty Hi-Fi and professional power amplifier is relatively stricter, dot matrix combination of the present invention has two kinds of connected modes.Mode one: can according to the mode of matrix arrangement, according to the single resistance value of coaxial loudspeaker, draw by mode in parallel after first connecting the resistance value matched with power amplifier, high pitch group contact and bass group contact separate serial or parallel connection, access built in sound box frequency divider after drawing the impedance matched.As the combination of A1-A2-A3, B1-B2-B3 matrix, setting single coaxial loudspeaker impedance is 4 Ω, A group loud speaker A1-A2-A3 series connection draws impedance 12 Ω, B group loud speaker B1-B2-B3 series connection draws impedance 12 Ω, A group after series connection, the parallel connection of B group draw impedance 6 Ω, meet the requirement of professional power amplifier and built in sound box frequency divider 4-8 Ω scope.Mode two: each coaxial loudspeaker unit is equipped with separately a built-in frequency divider, high pitch contact and bass contact access frequency divider respectively on request, each frequency divider passage one road power amplifier promotes, adopt multi-channel power amplifier to promote or more than two power amplifiers promotions, this mode is applicable to heavy caliber coaxial loudspeaker unit.
