The Chinese word 音响 (yīnxiǎng), meaning "audio equipment" or "sound system", is a coordinative compound formed by combining two semantically related characters: 音 (yīn), meaning "sound" or "tone", and 响 (xiǎng), meaning "to make a sound", "noise", or "echo". Together, they create a composite meaning that emphasizes the entirety of sound production and resonance, where 音 provides the core concept of "audio" and 响 adds the dimension of its emission, effect, or acoustic output, thus naturally extending to refer to the modern devices that produce and amplify sound.
