K

Kbps

每秒千位元。 數碼數據率衡量系統,通常 與高壓縮格式,如 AACDABMP3 等配 合使用。一般而言,數值越大,表示質量 越高。

加密密鑰

加密密鑰是一個字母數字序列,允許對資 料進行加密和解密操作,從而大大提高其 在網絡成員之間的共用安全性。

分貝 (dB)

用於表達聲音能力或強度相對差別的一種 單位。

數碼音訊

數碼音訊是一種已轉換為數值的聲音訊 號。 可透過多個聲道來傳送數碼聲音。 類 比聲音則只能透過兩個聲道來傳送。

D

DC(直流電)

直流電或恒向電流是電荷的穩定流動。 這 通常存在於導體中,如電線。 在直流電 中,電荷的運動方向相同,這與 AC(交流 電)不同。

頻率響應

即為揚聲器再現的頻率範圍,從最低頻率 到最高頻率。 最佳標準為 20-20,000 Hz( 赫茲),相對於個體而言,人類的聽覺範 圍通常更受限制。 但是,一個好的全程揚 聲器系統盡可能地重現此範圍,以便覆蓋 所有的變動。 個別驅動器受限於僅重現最 適宜於它的部分頻譜,因此,他們的響應 受到限制,但在設計完整聲音系統時,仍 是必須考慮的一點。

L

LivingSound

LivingSound™ 是一套由飛利浦提供的聲音

處理演算法,其目的在於提供空間增強, 讓聽衆在聽到聲音時會覺得喇叭與喇叭之 間的距離比實際上遠很多。

雙工(半/全)

全雙工是同時發送和接收數據的能力。 雙 工即表示全雙工。 例如:數據機在全雙工 模式下工作時,它可同時在兩個方向傳送 數據。 在半雙工模式下,數據機亦可在兩 個方向傳送數據,但不是同時。

數碼

使用二進位代碼 0s 1s 來編碼資訊的方 法。 很多無線手機和網絡均使用數碼技 術。

頻率

有規律間歇出現地屬性或情況。 對於聲 音,簡單來說,頻率是指有規律出現地空 氣壓縮和稀薄,從而聽覺到聲音。

M

M4A

Apple 在其 iTunes Music Store 中采用

的音訊檔案格式,在系統中通常顯示為 「.m4a」副檔名格式。 M4A 檔案使用比 MP3 更少的物理空間,產生更佳的音質。

輸入敏感度

揚聲器產生的 SPL(音壓級),功率為

1瓦,是基於標準的輸入頻率(通常為 1kHz,否則以揚聲器上的標注為準),在 距離為一米時測得的。

H

Hz(赫茲)

每秒的周期數,以物理學家 Heinrich Hertz 命名。

I

IP 地址

IP(互聯網協議)地址是讓電子裝置相互通 訊以及相互識別的唯一電腦地址。

阻抗

阻礙電路中電流流動的阻力。 這是喇叭施 加給放大器的有效電力負載,從而驅動其 運作,以歐姆衡量。
