Description
Technical field
The utility model relates to stereo set, relates in particular to a kind of active linear array sound equipment.
Background technology
Along with the era development of making rapid progress, people also constantly improve for the requirement of material progress and cultural and ideological progress, therefore, and the high-fidelity audio equipment of specialty very important that just seem.The linear array sound system is exactly the optimal selection that can reach professional high-fidelity music center effect.Particularly in recent years, mainly with the language public address, the demand of middle-size and small-size conference hall and general KTV and the performance of small-sized musical instrument constantly increases, also have higher requirement to small-sized linear array formula loud speaker in market, require sound reinforcement system sound pressure level in whole coverage evenly approaching, clear at remote sound.The horizontal directivity of linear array and single loud speaker it makes no odds.But, then occurring in vertical direction than highly directive, it spreads out as fan-shaped sample level, is formed with the radiation effect of " plate " shape of suitable thickness.When this audio disc points to the auditorium, can make effective radiation acoustic energy of array be controlled at audience area, make the large tracts of land spectators obtain stronger direct sound wave, avoid acoustic energy is radiated to metope and ceiling formation reflection on every side, reduce reverberation sound, improved the definition of sound and the intelligibility of language.But numerous audio amplifiers are formed arrays, will inevitably produce overlapping in the coverage, and will cause serious interference (phase place offsets or superposes), thereby produce irregular covering.When remote, sound pressure level or resolution then significantly reduce.And common linear array is when beginning to march into the arena, and mixed and disorderly sound equipment line can appear in installation process and a lot of power amplifier can't be put.On the other hand, long sound equipment line has increased the consumption to power, causes the big phenomenon of distorted signals and current loss.
The utility model content
The purpose of this utility model is at the deficiencies in the prior art, provides that a kind of transmission sound is steady, acoustic image is consistent, tone color is graceful, simple array sound equipment is installed.
For achieving the above object, the technical solution adopted in the utility model is as follows: a kind of active linear array sound equipment, comprise full frequency speaker and super woofer, the full frequency speaker side view is trapezoidal, full frequency speaker and super woofer all adopt the inverted phase type body structure to place, on full frequency speaker and super woofer, be equipped with angle part and connector, connect by connector between the front portion of full frequency speaker and the front portion of super woofer, connect and adjusting angle by the angle part between the rear portion of full frequency speaker and the middle part of super woofer.
As to improvement of the technical scheme, the angle part is provided with the angle part is fixed on positioning of rotating hole on the loud speaker, and two rows angle location hole spaced apart, each next door, angle location hole indicates the numerical value of angle, when representing loud speaker to be fixed on another loud speaker by this hole, the angle of vertical opening between two-loudspeaker.
As further improvement of these options, described angle hole has 9, and the subtended angle scope of two-loudspeaker is between 0 °～12 °.
As the improvement to above technical scheme, described sound equipment comprises one two 8 " super woofer and four full frequency speakers, one be the belt high pitch in four full frequency speakers, two is 4 " middle bass.
As to improvement of the technical scheme, be provided with power amplifier at the super woofer rear portion, added the DSP processing module in the power amplifier.
Active linear array of the present utility model is to be combined by super woofer and full frequency speaker.Super woofer is the active loudspeaker system, a super woofer can be with four full frequency speakers, super woofer adopts the inverted phase type structure, can produce powerful low frequency, increased dsp processor in the power amplifier module wherein, can carry out adjustment and the setting and the preservation of parameter in each according to different environment and different uses.Full frequency speaker is a passive loudspeaker systems, and loudspeaker adopts bugle formula belt high pitch, the sound exquisiteness, and the definition of sound and the intelligibility of language are than higher.Full frequency speaker can form the single waveguide source of sound front of not being damaged fully, the array horizontal displacement is greatly improved, in whole wave band broadband, interfere fine mutually, make the wave surface of generation very even, frequency response range with 120HZ-25KHZ, sound distribute steadily, the acoustic image unanimity, strengthen the designer greatly and set up the flexibility and the degree of freedom that alt partly covers, thereby solved the reluctant problem of common linear array.Angle by between the suspending way adjusting loud speaker reaches the output diffusion, makes the maximum effect of array.The utility model adopts △ active linear array sound equipment, and by a sound console and a peripheral processor, it is long thoroughly to have solved the sound equipment line, the phenomenon that distorted signals and current loss are big, thus deduce beautiful interesting to listen to music.Linear array directive property is strong, and the projection of sound is more accurate to have a power, far away, in, the sound pressure level near field is approaching, can reach the uniform purpose of sound field, and the shape-designing modern sense is pure.
Below in conjunction with accompanying drawing the utility model structure is described further.
