警官學院大講堂是(shi)滿足文藝演(yan)出、主題(ti)晚會(hui)、音(yin)樂會(hui)、召(zhao)開會(hui)議等現場擴(kuo)聲綜合性廳(ting)堂。本音(yin)響系統設計方案為(wei)各種(zhong)擴(kuo)聲形(xing)式提供優(you)良(liang)的音(yin)頻(pin)環境,產生優(you)秀(xiu)的音(yin)質效(xiao)果。
我司經(jing)充分理解圖紙及(ji)相(xiang)應要(yao)求(qiu)后,以全面滿足廳堂(tang)(tang)的功(gong)能(neng)要(yao)求(qiu)為(wei)原則,在(zai)設(she)計的過(guo)(guo)程中經(jing)過(guo)(guo)仔(zi)細的考慮(lv)和分析,找到并形成了一個(ge)適合警(jing)官學院大講堂(tang)(tang)的音響系統方案。
1、音響系統的需求定位與功能分析
根據警官(guan)學院大講堂實際使用(yong)中的功能需求,在設計過程中對該系統作(zuo)如下基(ji)本定位(wei):
!滿足(zu)文藝演出、主題(ti)晚會(hui)的擴聲要求;
!?滿足召開會議的擴聲要求
!滿足音樂演奏的擴聲要求
根據多功(gong)能廳的使用需求定(ding)位,我們確(que)定(ding)了本音響系統的主要功(gong)能是(shi):
1).??改善語言清晰(xi)度和音樂明(ming)晰(xi)度;
2).??提高節目源(yuan)的響度(du),擴展節目源(yuan)的動態;
3).??改進不同演出中的聲平(ping)衡;
4).??具有良好的聲(sheng)還原特(te)性(即保真(zhen)度);
5).??具有極(ji)佳的聲像自(zi)然度(即聲像一致性);
6).??在無樂隊演奏時重放伴奏音(yin)樂;
7).??可將部分節目信號存儲和(he)預置程(cheng)序以簡化(hua)操作(zuo);
2、音響系統的擴聲形式
根據(ju)相關要求,并(bing)依據(ju)對當前(qian)國內外各(ge)種多功能廳堂音(yin)響(xiang)系統的(de)調查研究,確定該廳堂擴(kuo)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)系統采用左、中、右(you)三(san)(san)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)道(dao)(dao)主(zhu)擴(kuo)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)與多點(dian)位(wei)補聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)相結合的(de)擴(kuo)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)方式(shi),觀眾(zhong)廳左、中、右(you)三(san)(san)個主(zhu)擴(kuo)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)道(dao)(dao),每個聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)道(dao)(dao)基(ji)本獨立(li)覆蓋(gai)全場(chang),在觀眾(zhong)廳設置多點(dian)位(wei)補聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)揚(yang)(yang)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)器,通過提(ti)高直(zhi)達聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)與混響(xiang)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)能比,從而提(ti)高語(yu)言清晰度(du),使(shi)得整個音(yin)響(xiang)系統能夠兼(jian)顧(gu)左、右(you)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)道(dao)(dao)立(li)體聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng),左、中、右(you)三(san)(san)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)道(dao)(dao)立(li)體聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng),單聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)道(dao)(dao)擴(kuo)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)等多種擴(kuo)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)形式(shi)。所有揚(yang)(yang)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)器均使(shi)用有源一(yi)體化揚(yang)(yang)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)器,保證了功放(fang)與揚(yang)(yang)聲(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)器間的(de)一(yi)致性。
舞臺音頻系統選型:
揚(yang)(yang)聲器是音(yin)響(xiang)系統中最(zui)(zui)重要的(de)(de)(de)組成部(bu)分。由于電(dian)子技(ji)術的(de)(de)(de)發(fa)展,聲系統中電(dian)子設備的(de)(de)(de)頻率響(xiang)應與相位(wei)響(xiang)應上的(de)(de)(de)處理已達到很高水平(ping),影(ying)響(xiang)音(yin)響(xiang)系統還原性(xing)能(neng)的(de)(de)(de)主(zhu)要瓶(ping)頸是換能(neng)器的(de)(de)(de)失真,因此揚(yang)(yang)聲器的(de)(de)(de)選用(yong)是對最(zui)(zui)終還音(yin)質量影(ying)響(xiang)最(zui)(zui)大、最(zui)(zui)有決定性(xing)的(de)(de)(de)一個環節。
本次(ci)揚聲器系(xi)統的(de)所有功能完(wan)全滿(man)(man)足(zu)使用的(de)要求(qiu)(qiu),觀(guan)(guan)眾廳設置左中(zhong)(zhong)右(you)立(li)體聲擴聲和多點位(wei)補聲擴聲系(xi)統。其中(zhong)(zhong)中(zhong)(zhong)央聲道獨立(li)覆蓋(gai)全場(chang)觀(guan)(guan)眾,左右(you)聲道覆蓋(gai)全場(chang)觀(guan)(guan)眾,均滿(man)(man)足(zu)并高于設計(ji)技術指標要求(qiu)(qiu)。另外,完(wan)全按照使用要求(qiu)(qiu)配置了舞臺流動(dong)返送監聽揚聲器和固定返送監聽揚聲器。
