Piezoelectric Crystal Earphone 20K Ohm Bare Wire Leads for Crystal Radio($13.10Value)

Description

Use this ProTechTrader CH905 piezoelectric crystal earphone with a high-impedance crystal radio receiver. Two tinned bare leads connect the single ceramic earpiece to a solder point or terminal. The passive element turns weak audio signals into sound without a battery or external amplifier. Use the earpiece for crystal set listening, transistor radio restoration, or signal tracing. A 42-inch twisted cable gives you room at the bench and suits soldered or terminal connections. Compare the 20K-ohm rating with the required load before connecting it. The package contains one beige earpiece without a 3.5mm plug or adapter. Supply the radio, project parts, and any extra connection hardware. Choose this wired earphone for DIY electronics when a standard low-impedance headphone loads the circuit. Check your receiver design, terminal method, and available cable path before installation. CH905 is a passive ceramic earpiece for receivers with weak audio output. It works for vintage radio repairs and bench demonstrations where a conventional headphone may load the circuit. The long twisted cable arrives with tinned ends for soldered or terminal connections. The package has a beige in-ear earpiece, while you supply the remaining radio parts. Compare your circuit requirements with the listed 20K-ohm rating before installation. This package doesn't include a plug or adapter.
