🔊 音响 = 音 sound + 响 echo/resound = a sound system or stereo
音 means sound and 响 means to resound or echo, so together they name the gear that makes sound loud: speakers, a stereo, a music center. The acoustics sense is literally sound-that-resounds.
响 — mouth 口 + village/hometown 乡
Originally written 響, combining 鄉 (village, phonetic) with 音 (sound), suggesting sound echoing through a hometown valley. The simplified form 响 replaces 音 with 口 (mouth) as a semantic hint and 乡 as the phonetic. It means sound, echo, or to make noise.
