Headphones are designed with a detachable boom microphone to enhance sound capture quality. These headphones feature a headband with two earpieces, each housing an audio driver. One or both earpieces include a directional microphone aimed at the user's mouth. The boom microphone, which can be attached to either earpiece, contains another directional microphone on a flexible boom. A processor in the headphones deactivates the earpiece microphone when the boom is connected, ensuring focused voice capture.
Headphones are widely used for superior acoustic performance and often include microphones for communication. Typical microphones in headphones are directional, aimed at capturing the user's voice while minimizing background noise. However, these microphones can sometimes amplify unwanted sounds like keyboard clicks. Boom microphones, positioned closer to the user's mouth, offer improved isolation of the user's voice from ambient noise but are often bulky.
The proposed headphones address these issues by integrating a removable boom microphone. The boom's flexibility allows it to be positioned optimally for voice capture. The headphones include a processor that detects when the boom is attached, activating the boom microphone and deactivating the earpiece microphones. This system effectively isolates the user's voice from background noise.
The boom microphone features a flexible design with a plug connector for easy attachment to the earpieces. It includes a directional microphone and a pulse density modulation circuit for converting analog signals to digital. A microcontroller processes these signals for transmission. The boom is made from semi-rigid material, ensuring it maintains its shape once positioned.
