Description

Omnibearing radiant disc shape combined loud speaker

The utility model relates to the equipment that the curtage variable is converted to sound wave.

Combination loudspeaker or title speaker system are in a loudspeaker enclosure several loudspeaker units and frequency divider to be housed, even also have the sound reproduction equipment of volume attenuator.

Now first-chop in the world is U.S. Mc Intosh XR22 combination loudspeaker and U.S. Magnepan Tympani IV combination loudspeaker, and Dali 104 combination loudspeakers of Denmark, the profile of its loudspeaker enclosure all is square, rectangle or strip, all belong to four jiaos of console modes, all be with the combination loudspeaker more than two when the hall uses, solved the problem of in the hall, listening stereo music, but its weak point is, stereo very not obvious under popular occasion, aerial sound can't represent.

Task of the present utility model is intended to overcome the deficiency of prior art, provides dish-like unsettled center, a kind of garden width of cloth to penetrate the combination loudspeaker of formula, not only can finish the function of general combination loudspeaker, can enlarge listening area again, particularly can represent aerial sound.

Task of the present utility model realizes by following measure:

Loudspeaker enclosure is the garden dish, and woofer, Squawker and high pitch loudspeaker and frequency divider etc. and relevant circuit wherein are housed.

Loudspeaker enclosure is made of institutes such as last disc 1, following disc 2, first garden spherical cap 3, second garden spherical cap 4, screws

On 45 ° along the line, 2 hole φ are being arranged respectively on the side face of the garden of last disc 1 ₅, as the fixing usefulness that goes up disc 1 and following disc 2 required screw perforations.

On the garden side face of following disc 2, above-mentioned corresponding hole is arranged also, as the usefulness of hold-down screw perforation.On the side face of garden, φ is respectively arranged every 45 ° ₁And φ ₂The effect of main suction hole and secondary sound hole is played in the hole.

The hole φ that at the center of last disc 1 and following disc 2 diameter to be arranged respectively be 300mm ₄, there is platform both sides, are used for placing and the fixing usefulness of woofer.

Respectively there is a hole φ on top at first garden spherical cap 3 and second garden spherical cap 4 ₃, as the suction hole of woofer.

In the cavity of last disc 1 and following disc 2, along 360 ° of garden weeks, at skin a high pitch loudspeaker is installed respectively every 45 °, totally eight, at internal layer a Squawker is installed respectively, totally eight; Also can at skin a high pitch loudspeaker be installed respectively, totally four, at internal layer a Squawker be installed respectively, totally four every 90 °.Can both clearly hearing all around of the hall enlarged listening area by stereo sound like this.

Between last disc 1 and following disc 2, leave the space as main sound hole.

Frequency divider is arranged in the cavity, input signal is divided into several frequency bands, be added to respectively on the loud speaker of different frequency scope.

Prior art all is that loud speaker is installed at grade, and the speed of sound of three kinds of loud speakers is almost imported the hearer simultaneously into, so the level fuzzy.

The utility model adopts Eight-Diagram partial mechanism, binaural is divided into 2 * 2 or 2 * 4 sound channels, every sound channel is divided three zones, it is high pitch, middle pitch and bass zone, adopt different sound-absorbing materials according to three kinds of different audio frequencies, loud speaker adopts series connection, parallel connection method is finished, establish high pitch in each sound channel, each one of Squawker, bass area is sent sound into corresponding sound channel respectively by two woofers by partial mechanism, motive force with loudspeaker cone produces windstream, compression reflected radiation by partial mechanism is gone out, three kinds of loud speakers are vertically arranged on same axis to the bass order by high pitch and have been realized the time difference that loud speaker utilizes the time difference to tell three different sound signals more significantly, make high pitch, middle pitch, the level of bass is clearly more demarcated.

Partial mechanism is with four thick 40～50mm, and the softwood of respective width and length is made, and mainly plays a part to divide a sound channel and the even bass that divides, and realizes the time difference on same axis, and is convenient to the fixedly usefulness of high pitch and Squawker.

Between upper and lower disc, leave the space as main sound hole, on the garden side face of following disc 2, φ is arranged ₁And φ ₂As secondary sound hole, when the utility model is suspended on when aerial, the sound of different frequency can radiate in all directions, has enlarged listening area, and stereo extremely obvious, the level of high pitch, middle pitch, bass is clearly more demarcated.

Loudspeaker enclosure of the present utility model can be made with different materials:

(1) is made with natural black jade in Lantian or natural marble, is fit to use in professional movie theatre, dancing hall, the luxurious parlor.

(2) be made with wood materials, be used for the dance hall and the general hall.

(3) be made with cast aluminium alloy, rainproof corrosion protection is applicable to crossing, street, the center, square of cities and towns, enterprise.

Compared with the prior art the utility model has obtained following outstanding effect:

1. prior art is placed on around the hall, and the listening zone is only limited at central area, and the utility model is suspended on the central authorities in hall, and the listening zone relates to whole hall, has enlarged listening area.

2. prior art is stereo not obvious under popular occasion, in the utility model, high pitch, middle pitch, woofer order are vertically arranged on same axis and have been realized the time difference, make that the level of high, medium and low sound is clearly more demarcated, can represent special sound effects such as takeoff and landing, air battle, Lei Wu, rain sound, give super enjoyment on the spot in person.

Fig. 1 is the structural representation that the comprehensive width of cloth is penetrated formula garden dish combination loudspeaker.

YD ₁Be high pitch loudspeaker, YD ₂Be Squawker, YD ₃It is woofer.

Fig. 2 is the punch position schematic diagram of following disc 2 and second garden spherical cap 4.
