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.
