During modern public address is used, also more and more higher to the requirement of sound pressure level (acvoustic units of volume) along with the increase of site area and increasing of attendance, cover to realize wider sound.
In order to improve sound pressure level, bugle structure commonly used has namely installed bugle additional before high pitch drives, and to promote public address efficient, improves sound pressure level.But single bugle and since high-pitched driver to bear power limited, thereby, have only and adopt many bugles to form arrays, synchronous working could improve sound pressure level significantly, to satisfy the public address demand.
But along with the increase of bugle quantity, mutual interference effect also increases thereupon, causes that the distortion effect strengthens, and makes the public address both poor sound quality.
Produce this problem and have its source in, the sound wave that high-pitched driver sends, the path difference that produces at place, bugle outlet causes.Because the velocity of sound constant (being generally 340 meter per seconds) path difference can cause the time difference, namely the sound wave that sends of different bugles can not arrive this position simultaneously.This will cause phase difference between sound wave, and mutual interference effect takes place, and make system frequency response produce local increasing, partial cancellation, thus cause the public address effect to worsen, reduction degree is reduced greatly.
The utility model content
In order to overcome prior art medium-high frequency public address lower tone, deficiency that reduction degree is low, it is a kind of by implanting the path compensation effect of the phase plug in the trunnion that the purpose of this utility model is to provide, the interference that elimination produces because of path difference, optimize the public address effect, improve the implanted phase plug Horn of system reducing degree and fidelity.
To achieve these goals, technical solution adopted in the utility model is as follows:
A kind of public address comprises with implanting phase plug formula Horn: high-pitched driver, the trunnion, implanted phase plug, the bugle guide plate that are made of left and right symmetrically arranged bugle trunnion side plate; The entrance of described trunnion links to each other with high-pitched driver, and outlet links to each other by adpting flange with the bugle guide plate; Described implanted phase plug is connected with bugle trunnion side plate by pilot pin, is fixed between two parties in the trunnion internal channel.
Described trunnion is left and right symmetrical structure, is connected as one by bolt.
Described implanted phase plug is fusiformis, its profile and trunnion inwall coupling.
This utility model is implanted " fusiformis " phase plug in the bugle trunnion, the sound wave that high-pitched driver sends is propagated along the trunnion inner chamber, after running into phase plug, then be divided into equal two parts, the passage that forms along trunnion inwall and phase plug arc-shaped outer surface " detours " behind the phase plug respectively, arrive the outlet of aditus laryngis simultaneously, again coupling.Because phase plug presents two ends point, middle thick " fusiformis " structure, thereby on different cross section, the distance that sound wave detours is different, and the distance that this detours, this path difference exactly.Therefore, by the path compensation effect of phase plug, finally make sound wave at place, bugle outlet, form equiphase wave surface.Like this, when a plurality of bugles were formed array, whole array formed phase wave surfaces such as continuous, and mutual interference effect is minimum.
The beneficial effects of the utility model are: by the path compensation effect of implanted phase plug, make the variation of the propagation characteristic generation of sound wave, namely be converted to cylindrical wave by spherical wave, and this characteristic, make it have outstanding advantage: 1, implant " fusiformis " phase plug bugle, because " compensation of delay " function of phase plug, make the system phase unanimity, interference effect when greatly having reduced the combination of many bugles, reduced the frequency response distortion (comb-filter effect) because interference causes, sound quality deterioration, effectively reduce the living interference between the high frequency bugle, improve reduction degree, significantly improved high frequency public address tonequality." fusiformis " phase plug of 2 bugles, its effect is similar to the optical male lens, makes beam of sound present " focusing " effect in the vertical direction, and directive property significantly narrows, and is highly directive.Thereby, according to energy conservation principle, under equal conditions, compare traditional bugle, owing to " focusing " effect improves public address efficient, sensitivity increases, and with under the power, its sound pressure level is bigger.
3, because the utility model has been realized the waveform transformation function, namely be converted to cylindrical wave by spherical wave, the sound reinforcement system that many bugles are formed, its sound transmission efficient improves greatly.In theory, the efficiency of transmission of linear sound doubles than conventional point sound source, and this mainly is based on the cylindrical wave of line source and the spherical wave property difference of point sound source.In actual applications, because body structure and air are to influence of various factors such as sound waves of different frequencies difference in attenuation, can't reach one times of theoretical efficient and promote (actual measurement is about 0.6-0.8 doubly), but through actual measurement, compare traditional bugle system, its public address efficient, transmission range have the raising of highly significant.
