產(chǎn)品詳細說明

產(chǎn)品規(guī)格參數(shù):

型號:  系統(tǒng):2路同軸揚聲器 低音:銀色電鍍聚合錐形盤(清晰亮麗的中高頻的秘訣) 高音:50mmpei高音和一個13mm超高音(清晰通透的高頻達22KHz明亮而不吵耳) 磁體:20 0Z (高密度大磁鐵,功率強勁的保證) 音圈:1"KSV25mm 耐高溫音圈,長期穩(wěn)定工作的保證! 功率:100w 額定功率,200w 最大功率 阻抗:4歐姆 頻率反應:40Hz - 22K Hz 靈敏度:92dB/M.W (靈敏度高表示容易推動,高頻清晰中頻富有彈性)和十幾個國內(nèi)外一線品牌套裝喇叭對比,它是一款真正性價比非常高的好喇叭,尤其在人聲方面表現(xiàn)突出,人聲清晰,中音飽滿圓潤,低頻適中,每個型號的音樂表現(xiàn)力各有不同。整體聽感明亮通透,音域?qū)拸V,低音結實有力,中頻人聲飽滿自然,高音亮而不刺。
揚聲器的主要性能指標有:
靈敏度、頻率響應、額定功率、額定阻抗、指向性以及失真度等參數(shù)。   
1、額定功率   揚聲器的功率有標稱功率和最大功率之分。標稱功率稱額定功率、不失真功率。它是指揚聲器在額定不失真范圍內(nèi)容許的最大輸入功率,在揚聲器的商標、技術說明書上標注的功率即為該功率值。最大功率是指揚聲器在某一瞬間所能承受的峰值功率。為保證揚聲器工作的可靠性,要求揚聲器的最大功率為標稱功率的2~3倍。   
2、額定阻抗   揚聲器的阻抗一般和頻率有關。額定阻抗是指音頻為400Hz時,從揚聲器輸入端測得的阻抗。它一般是音圈直流電阻的1.2~1.5倍。一般動圈式揚聲器常見的阻抗有4Ω、8Ω、16Ω、32Ω等。   
3、頻率響應   給一只揚聲器加上相同電壓而不同頻率的音頻信號時,其產(chǎn)生的聲壓將會產(chǎn)生變化。一般中音頻時產(chǎn)生的聲壓較大,而低音頻和高音頻時產(chǎn)生的聲壓較小。當聲壓下降為中音頻的某一數(shù)值時的高、低音頻率范圍,叫該揚聲器的頻率響應特性。   理想的揚聲器頻率特性應為20~20KHz,這樣就能把全部音頻均勻地重放出來,然而 這是做不到的。每一只揚聲器只能較好地重放音頻的某一部分。   
4、失真   揚聲器不能把原來的聲音逼真地重放出來的現(xiàn)象叫失真。失真有兩種:頻率失真和非線性失真。頻率失真是由于對某些頻率的信號放音較強,而對另一些頻率的信號放音較弱造成的,失真破壞了原來高低音響度的比例,改變了原聲音色。而非線性失真是由于揚聲器振動系統(tǒng)的振動和信號的波動不夠完全一致造成的,在輸出的聲波中增加一新的頻率成分。   
5、指向特性   用來表征揚聲器在空間各方向輻射的聲壓分布特性,頻率越高指向性越狹,紙盆越大指向性越強
振膜方面:
低音單元的振膜種類繁多,有鋁合金振膜、鋁鎂合金振膜、陶瓷振膜、碳纖維振膜、防彈布振膜、玻璃纖維振膜、丙烯振膜、紙振膜等等。采用鋁合金振膜、玻璃纖維振膜的低音單元一般口徑比較小,承受功率比較大,而采用強化紙盆、玻璃纖維振膜的低音單元重播音樂時的音色較準確,整體平衡度不錯。
Product Specifications:

Model: System: 2-way coaxial speaker bass: silver plating polymerization conical (clear and bright in the secret of the high-frequency) Treble: 50mmpei treble and a 13mm ultra-high tone (the clear, crisp high frequency up to 22KHz bright but not deafening) magnet: 20 0z (high-density magnets, power strong guarantee) voice coil: 1 "KSV25mm high temperature voice coil, long-term stability guarantee! power: 100W rated power, 200W maximum power Impedance: 4 ohms Frequency response: 40Hz - 22K Hz Sensitivity: 92dB/MW (high sensitivity, easy to promote, high-frequency clarity IF elastic)
And more than a dozen domestic and foreign brands speaker package comparison, it is a true cost is very high, a good speaker, especially in vocal performance, voice clear, full and mellow tenor, low-frequency moderate music performance of each model force varies. The overall sense of hearing is light and airy, wide range, strong and powerful bass, full of natural IF vocal, bright treble without thorn.
The speaker key performance indicators:
Sensitivity, frequency response, rated power, rated impedance, directivity and distortion parameters.
Rated power speaker power nominal power and maximum power of the points. The nominal power of said rated power, power without distortion. It refers to the maximum input power of the speakers at rated distortion range permitted in marked on the speaker trademarks, technical manuals, power is the power value. The maximum power of the speaker in a moment can withstand peak power. , For ensuring the reliability of the speaker work, requiring the maximum power of the speaker for a nominal power of 2 ~ 3 times.
Rated impedance speaker impedance and frequency. Rated impedance audio is 400Hz, measured from the speaker input impedance. Usually it is a voice coil DC resistance of 1.2 to 1.5-fold. The general dynamic speaker common impedance 4Ω, 8Ω, 16Ω, 32Ω and other.
3, the frequency in response to a speaker with the same voltage as the audio signals of different frequencies, the sound pressure generated will produce changes. General audio sound pressure, sound pressure generated in the low audio and audio smaller. When the decrease in sound pressure is high, the bass of a certain value of the audio frequency range, called the frequency response characteristics of the speaker. Speaker frequency characteristics should be 20 ~ 20KHz, so that we can all even audio replay, but this can not be done. Each speaker can only be reproduced in a certain part of the audio.
4, distortion speaker can not realistically reproducing the original sound out of the phenomenon is called distortion. Distortion in two ways: frequency distortion and nonlinear distortion. The frequency distortion is due to the strong signal playback on certain frequencies, while the weaker frequency signal playback caused destruction of the proportion of the original level of sound distortion change the soundtrack Voice. The nonlinear distortion is completely consistent enough due to the vibration of the speaker vibration system and signal fluctuations caused by the increase in the output of the acoustic wave in a new frequency component.
5, the directivity characteristics to the characterization the speaker radiation in all directions of the space sound pressure distribution characteristics, the more narrow the higher the frequency, the directivity, the bigger the cone pointing to the stronger
Diaphragm areas:
Woofer diaphragm wide range of aluminum diaphragm, aluminum-magnesium alloy diaphragm, ceramic diaphragm, the diaphragm of carbon fiber, Kevlar diaphragm, glass fiber diaphragm, propylene diaphragm, paper diaphragm. Aluminum alloy diaphragm, glass fiber cone woofer general diameter is relatively small, relatively large power handling, while the use of enhanced cone, glass fiber cone woofer replay music sound more accurately, good overall balance.
