Background technology
Remolding sensitivity bass horn highly sensitive of specialty loudspeaker, when audio amplifier is used for family or cinema, just elements attenuate such as high pitch resistance, must can cause unnecessary distortion like this.And wish that its part-frequency point is lower, this just requires that bugle high pitch has enough low low-frequency cut-off frequency.
Utility model content
For solving prior art problem, the technical scheme that the utility model provides is:
A kind of type horn loudspeaker, comprises casing, bass unit, bugle and voice unit,
Described casing has two bass units, described bugle is positioned at casing top; Described bugle comprises bugle and amplifies end, bugle transitioning end and bugle support; Described bugle support is for supporting bugle and connect box, and the sensing mouth of described bugle amplification end and bass unit are at grade; The sensing mouth that described bugle amplifies end is rectangle, and it is the bucket-shaped storage mouth that is accommodated in gradually that bugle amplifies end overall, and storage mouth is rectangle, and described storage mouth is connected with bugle transitioning end; The inner surface that bugle amplifies end is plane; Described bugle transitioning end entirety is accommodated in storage mouth gradually for berrette file shape, and the storage mouth of bugle transitioning end is connected with voice unit.
Preferably, the height that described bugle amplifies the sensing mouth of end is 630mm, and width is 380mm, and length is 235mm.
The beneficial effects of the utility model: put by rational bugle position and the design of bugle shape, length and sensing open area, decrease the element of frequency divider, avoid the distortion frequency range that high pitch is larger, thus reduce distortion.Reduce acoustic interference when casing and the size controlling bass casing.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of type horn loudspeaker, comprises casing 1, bass unit 2, bugle and voice unit 6,
As shown in Figure 1, described casing 1 has two bass units 2, described bugle is positioned at casing 1 top; Described bugle comprises bugle and amplifies end 3, bugle transitioning end 4 and bugle support 5; Described bugle support 5 is for supporting bugle and connect box 1, and the sensing mouth of described bugle amplification end 3 and bass unit 2 are on same horizontal plane; The sensing mouth that described bugle amplifies end 3 is rectangle, and bugle amplifies end 3 entirety for the bucket-shaped storage mouth that is accommodated in gradually, and storage mouth is rectangle, and described storage mouth is connected with bugle transitioning end 4; The inner surface that bugle amplifies end 3 is plane; Described bugle transitioning end 4 entirety is accommodated in storage mouth gradually for berrette file shape housing, and the storage mouth of bugle transitioning end 4 is connected with voice unit 6.Described backboard 7 is electrically connected with frequency divider, and backboard 7 is the audio input end of loud speaker.Backboard 7 of the present utility model has two, and two backboards 7 are respectively as bass and high pitch full acoustic frequency input, and treble audio output.
The utility model, mainly through rational size design, decreases frequency division device, avoids the distortion frequency range that high pitch is larger, thus reduces distortion.
Utilize the change of the geometry of bugle, make the high-frequency sensitivity of high pitch reduce and reduce low-frequency cut-off frequency.The length of bugle, in very large range, affects the high-frequency sensitivity of loudspeaker, and trombone angle or cornet angle all can make the high-frequency sensitivity of high pitch reduce.But unlike, trombone angle can also reduce its low-frequency cut-off frequency.Cornet angle is then contrary.At this time according to the sensitivity of bass unit, and design the bugle of appropriate length, to reach the Natural matching of bass and high pitch sensitivity.
As shown in Figure 2, a points to the different bugle of open area equal length, and b is low-frequency cut-off frequency and the high frequency attenuation frequency of the bugle of different length.The bugle length that aperture area is identical and the high-frequency relation of its low-frequency cut-off frequency: the low-frequency cut-off frequency of bugle A is 1000HZ, and high frequency is undamped; The low-frequency cut-off frequency of bugle B is 800HZ, and high frequency is decayed from 8KHZ; The low-frequency cut-off frequency of bugle C is 650HZ, and high frequency is decayed from 5KHZ; The low-frequency cut-off frequency of bugle D is 500HZ, and high frequency is decayed from 3KHZ.
As shown in Figure 3, the difference of bugle A and bugle D when designing frequency divider: wanting audio amplifier has good sound, the part-frequency point of its high pitch and bass will be taken at about 1500HZ, and this just requires that the low-frequency cut-off frequency of high pitch is at 750HZ or lower, so can avoid the larger frequency range of high pitch distortion.As schemed E display: the low-frequency cut-off frequency of bugle A is 1000HZ, and its desirable part-frequency point is 2000HZ or more, by drawing A1 curve after three rank frequency divisions (figure tri-), as can be seen from A1 curve, its acoustic pressure is obviously high than bass acoustic pressure, and such distortion is just large, and tonequality is just bad.If that wants the acoustic pressure of A1 to drop to bass is the same, the R1 of dotted portion in figure tri-will be increased, the elements such as R2, so just bring new distortion.As schemed F display: the low-frequency cut-off frequency of bugle D is 500HZ, and its desirable part-frequency point is 1000HZ or more, and by drawing D1 curve after three rank frequency divisions (figure tri-), as can be seen from D1 curve, its acoustic pressure fundamental sum bass is the same.Frequency division element has been used, so distortion is few compared with A1 due to few.
The height amplifying the sensing mouth of end based on above reason bugle of the present utility model is 630mm, and width is 380mm, and it is 235mm that bugle amplifies end length.The length of casing 1 is 505mm, and width is 540mm, is highly 920mm.
