受 信 機(じゅしんき)

じゅしんき

noun

receiver; receiving device

1. receiver; receiving device (for radio, television, or other signals)

An electronic device that receives and decodes transmitted signals — radio, television, telemetry, satellite, GPS, or other wireless communication. A technical but widely understood word, common in user manuals, news about broadcasting, and explanations of wireless technology.

ラジオの受信機(じゅしんき)を買(か)った。

I bought a radio receiver.

この受信機(じゅしんき)は海外(かいがい)の放送(ほうそう)も受信(じゅしん)できる。

衛星(えいせい)からの信号(しんごう)を正確(せいかく)にとらえるためには、高性能(こうせいのう)の受信機(じゅしんき)が必要(ひつよう)だ。

To accurately capture signals from satellites, a high-performance receiver is needed.

Compound of 受信(じゅしん) (receiving a signal) and the suffix 〜機(き) (machine, device). The word is paired symmetrically with 送信機(そうしんき) (transmitter). In everyday conversation about consumer electronics, Japanese speakers more often name the specific device — ラジオ (radio), テレビ, GPS, and so on — and reserve 受信機(じゅしんき) for technical discussion.
