Piezoelectric Crystal Earphones 20K Ohm High Impedance 3.5mm Jack

This package contains two piezoelectric ceramic earphones for DIY electronics and compatible radio projects. Each earphone has a 3.5mm audio jack for connection with a matching circuit interface. The specified 20,000ohm impedance suits project designs that require a highimpedance listening component. Use the pair when building crystal radio circuits or conducting related electronics experiments. They also support transistor radio projects designed around the same electrical and connector requirements. Confirm that your planned circuit accepts both the stated impedance and 3.5mm jack before connecting either earphone. Each ceramic earphone uses a brass diaphragm as part of its piezoelectric construction. A 42inch twisted black wire provides ample distance between the earphone and project connection. All wire connections come soldered, so builders can examine the finished joints before use. The package quantity includes two matching earphones for one shared setup or separate circuits. Their 3.5mm audio jacks connect with compatible sockets in custom electronics and radio assemblies. Keep the connector type, 20,000ohm rating, and circuit design aligned when choosing these components. This product is not a toy and is designed for use by teens and adults ages 13 and up
