Abstract

The present invention relates to the technical field of audio equipment, and specifically to a matrix high pitch KTV sound box. The matrix high pitch KTV sound box is mainly composed of a box body, a frequency divider, a large-power bass speaker, a matrix high pitch speaker, etc. The matrix high pitch forms a matrix by closely arranging nine common paper cone high pitch speakers on a same panel. The adjacent eight high pitch speakers are used as high pitch speakers. The intermediate one speaker is used as an ultra high pitch speaker. As the adjacent eight high pitch speakers form a loop with a mode of parallelly connecting two serial connections of which each is composed of four high pitch speakers, the power of eight high pitch speakers is eight times of single paper cone high pitch speaker, and the problem of small power of paper cone high pitch speaker is settled. When the music is broadcasted, the high pitch matrix speaker is equal with one large bugle. The transmission range is long and the tone quantity can guarantee the characteristic of paper cone high pitch speaker. Namely the tone quantity is smooth and is not harsh. The listening effect is excellent. The ultra high pitch speaker can better represent the detail of music. The matrix high pitch speaker and the large-power bass speaker form the music broadcasting system of the invention.

Description

Matrix high pitch KTV sound box

Technical field:

The present invention relates to the stereo set technical field, it exactly is a kind of matrix high pitch KTV sound box, KTV is exactly Karaok TV (OK a karaoke club ok), and KTV is meant that one group of guest is at a consume activity that is equipped with the picture display screen of good stereo set, high definition and has the separate space in comfortable guest activities zone to play Karaoka.

Background technology:

At present, common KTV audio amplifier is used widely, and all there is two large problems in the known KTV audio amplifier of this kind aspect loudspeaker, and 1, the cone high pitch: the tonequality exquisiteness, sense of hearing is good, but power is little, and range is near, is difficult to satisfy the K song requirement of big room; 2, bugle high pitch: power is big, and far firing range, but sound point are ear-piercing and metallic sound is serious, and the details of a lot of music is difficult to show.

Summary of the invention:

The objective of the invention is to: solve the weak point of present existing product technology, a kind of matrix high pitch KTV sound box is provided.

The technical solution adopted for the present invention to solve the technical problems is: a kind of matrix high pitch KTV sound box, it mainly is made up of casing, frequency divider, powerful bass and matrix high pitch etc.

Described matrix high pitch, promptly be close to and be arranged on the same panel by 9 common low basin high pitchs, form a matrix, 8 high pitchs are to use as high pitch on every side, and middle 1 used as the superelevation sound, 8 high pitchs are to constitute the loop by 4 series connection mode in parallel again around the cause, so its power is 8 times of monomer cone high pitch, have solved the little problem of low basin high pitch power.When playback, the high pitch matrix is equivalent to 1 big bugle in pronunciation, so its range is far, tonequality can guarantee the characteristic of cone high pitch again.Be the tonequality exquisiteness, not ear-piercing, sense of hearing is comfortable.Middle superelevation sound can show the details of music better, and matrix high pitch is equipped with powerful bass horn again, promptly constitutes playback system of the present invention.

The two 8 cun basses of this matrix high pitch collocation, single 8 cun basses, two 10 cun basses, single 10 cun basses, 12 cun basses are suitable equally.

The invention has the beneficial effects as follows: can solve existing KTV audio amplifier well when adopting the cone high pitch, power is little, and range is near, and the tonequality when adopting the bugle high pitch is bad, the uncomfortable problem of sense of hearing.

Embodiment:

Below in conjunction with accompanying drawing, the present invention is succinctly described.

As shown in the figure: this matrix high pitch is close to be arranged on the same panel by 9 common cone high pitchs forms matrix, high pitch panel and bass panel are not at grade, but separate two boards, constitute the angle of 160 degree, in actual use, adjust the angle of left and right two audio amplifiers, the matrix high pitch that makes left and right sides audio amplifier almost at grade like this can be so that whole sound field be broad more.Left plate, interior lower plate, right plate, lower plate, back plate, upper plate is by each other with an angle of 90 degrees connection that combines.

Lower plate 09 and lower plate 08 parallel coincidence among the present invention, the perforate of the corresponding lower plate 08 of the perforate of interior lower plate 09, left plate 01 and right plate 10 respectively with vertical coincidence of interior lower plate 09 the right and left, back plate 13 and vertical coincidence the in interior lower plate 09 back, about back plate two vertical edges respectively with the vertical edges of left plate 01 and right plate 10 with miter angle to being connected into an angle of 90 degrees, top alignment and highly identical, bass horn plate 02 is spent angles to after being connected into " V " font with loudspeaker plate 06 middle both sides with 160, the right and left is fixed with the inboard of left plate 01 and right plate 10 respectively, and is fixing above the following and interior lower plate 09 of " V " font.Upper plate 14 is fixed on the top of left plate 01, right plate (10), bass horn plate 02, loudspeaker plate 06, back plate 13, and each limit alignment, has so just formed an empty van body.Phase-reversing tube is fixed on glue on the paraphase hole of back plate 13, and terminal box 12 usefulness screws are fixed on the wiring hole of

back plate

13, and 07 of superpower base passes lower plate 08 and interior lower plate 09 pairing hole, is fixed on the lower plate 08 with screw.9 high pitch correspondences are installed on the loudspeaker plate 06, and fix with screw, form a matrix.Bass horn 03 correspondence is installed on the bass horn plate 02 and with screw fixes.Iron net 04 is fixed on the face of bass horn plate 02 and loudspeaker plate 06 with screw at last.Final this matrix high pitch KTV sound box of forming.
