About this product


Product overview

• Sub-miniature condenser microphone component that is ideal for recording audio when installed into a PCB circuit
• Omnidirectional design to pick up audio from a single direction, such as the speaker, isolating any background noise to prevent any distortion or interference
• A sensitivity of -60dBv allows an excellent response by the microphone to quieter sounds

>Special Feature
• Electret condenser design allows the microphone to be smaller and to be powered from a smaller voltage

What would I use this microphone with?
This microphone is small in design and can be used as part of any soldering project to build your own microphone with any design or connector you require. This will allow you to use the microphone for various projects and in a variety of ways such as building a microphone or a two-way communication device.

What is the advantage of having a condenser microphone?
This type of microphone is ideal for becoming a part of a PCB circuit that will record audio. Its small design will allow it to be easily mounted in a housing without obstructing vital circuits. This will allow you to create a small custom made microphone of any design to suit your needs.

What position does the condenser microphone pick up sound from?
This microphone has a cardioid pattern which allows it to pick up audio from a single direction. This reduces the amount of background noise that it will pick up from other directions and will allow you to record your audio without any interference.

On the circuit diagram it looks a bit pixelated but I'm guessing that the battery is 1.5 volts. Is that correct?
Asked by: paulr
Yes that is correct
