Acoustic guitar意思

"Acoustic guitar" 是指一種原聲吉他，它通過琴弦振動琴橋上的音梁，再通過共鳴箱（音箱）放大聲音。這種吉他通常沒有電子擴音系統，因此它依賴於自身的結構來產生聲音。與電吉他不同，電吉他需要通過連線到音箱的拾音器來放大聲音。

Acoustic guitars come in various shapes and sizes, including dreadnought, concert, auditorium, and jumbo, each with its own unique tonal characteristics. They are commonly used in folk, country, bluegrass, and rock music, among other genres, and are often played solo or in small ensembles.
