Description

Multi-functional linear array audio amplifier

Technical field

The utility model relates to a kind of audio amplifier, the especially a kind of multi-functional linear array audio amplifier that can change between common audio amplifier and linear array audio amplifier.

Background technology

Traditional linear array audio amplifier in use can only horizontal positioned be used, be applicable to large occasion and form the use of linear array array, audience region is divided into far and near different region, so different audio amplifiers meets the audience in different regions, in big-and-middle-sized occasion, make audience can hear all the time the sound that a point sends, make sound pure, clear, and traditional sound equipment in being used, big-and-middle-sized occasion have very large advantage; But linear array sound equipment is in list several uses only or seldom, and the region of covering is just restricted, and in small-sized place, uses and has just been subject to limitation.Therefore for middle-size and small-size performance enterprise, should meet medium and small occasion, meet again big-and-middle occasion, will prepare so very eurypalynous audio amplifier series, to middle-size and small-size performance enterprise, be a very large burden undoubtedly, no matter from fund input, the storage of product, the supporting etc. of equipment all can produce very large spending, so how can allow these enterprises save lower unnecessary expenditures, can be applicable to the use of various large, medium and small occasions again? therefore, design a kind of both can use separately (as conventional case, using), can be combined into again the multi-functional linear array audio amplifier that linear array is used, the current technical issues that need to address.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of both can use separately (as conventional case, using), can be combined into again the multi-functional linear array audio amplifier that linear array is used.

The technical scheme in the invention for solving the technical problem is:

Multi-functional linear array audio amplifier, by casing, bass unit, alto units and voice unit form, on the antetheca of casing, there is bass unit, alto units and voice unit sender, bass unit, alto units and voice unit are all fixed on the antetheca of casing and are corresponding with sender separately, bass unit is at foot, alto units is at middle part, voice unit is at topmost, described alto units is located in middle pitch cavity, the antetheca of middle pitch cavity is exactly the antetheca of casing, the Horn of voice unit is fixed on Horn change-over panel, voice unit is fixed on the antetheca of casing by Horn change-over panel with fast-assembling screw, unload fast-assembling screw and rotate Horn change-over panel, Horn change-over panel drives Horn half-twist together with voice unit, realize the pattern conversion of conventional case and linear array case, on the antetheca of casing, be provided with four paraphase holes, four paraphase holes divide and are located at voice unit both sides, in the place ahead of bass unit, be provided with bass phase-plate.

As a kind of preferred version of the present utility model, described alto units has two mediant trumpets, the as a whole formula cavity of described middle pitch cavity, and two mediant trumpets are arranged in integral type cavity in left-right layout mode.

As another preferred version of the present utility model, described alto units has two mediant trumpets, described middle pitch cavity be two with minute cavity of left and right mode layout, two mediant trumpets divide and are located in two minutes cavitys.

As another preferred version of the present utility model, on the inwall of casing, be fixed with four paraphase hole pipes, four paraphase hole Guan Yusi paraphase holes are corresponding one by one.

Compared with prior art, the utlity model has following characteristics,

1. casing has been taken into account conventional boxes and two kinds of bodies of linear array case: this casing has been taken into account two kinds of structures of conventional case and linear array case in design, and endways substantially similar with general conventional case ratio, horizontal positioned is again a linear array case; On casing, the collet of existing conventional case can support placement with support simultaneously, has again the suspender member of linear array case; From the existing vertical iron handle of handle when horizontal positioned (can avoid the drawback of wood stock water again), there is again the wood stock of level simultaneously.

2. the applicable layout of vertically placing again applicable horizontal positioned composition linear array unit of the layout of unit has adopted one can rotate freely the middle pitch of 90 ° of high pitchs, two high energy energy, a high-octane bass, on bass, used phase place compressive plate simultaneously, the bright high pitch of simple and honest bass of having taken into account conventional boxes from configured in one piece has increased again the dynamics that linear array requires, and is also applicable in addition the layout of conventional case and linear array case the layout of high, medium and low sound.

3. adopted the common Horn of foursquare high pitch change-over panel no matter be from all can not be applicable to conventional case applicable linear array case again under indeclinable state in shape or from waveguiding structure simultaneously, the design has adopted a foursquare change-over panel dexterously, the rotation that can make Horn do like a cork 90 ° is installed, like this no matter all draw sword and separate from the limitation in shape or the angle of waveguide, coordinate magnet attraction that the iron net Installation Modes of iron net and screw is installed keyset fast Installation Modes are installed simultaneously and make the conversion of bugle not only laborsaving save trouble not only but also fast that seem, thereby reached, make the conversion fast and easy of audio amplifier between conventional boxes and linear array case, the object that can be applicable to various occasions.
