Abstract
A Bluetooth microphone (10) comprises a controller (MCU) and Bluetooth transceiver (12) arranged to: establish a Bluetooth paired connection with a device; establish an Advanced Audio Distribution Profile, A2DP, connection with the paired device to receive a sequence of packets from the paired device for decoding by the microphone; and establish a Serial Port Profile, SPP, connection with the paired device for simultaneously transmitting a sequence of packets based on a microphone transducer signal to the paired device as the received sequence of packets are being decoded for transmission to a set of headphones.
Claims15
A Bluetooth microphone comprising:
- a transducer arranged to provide an electronic representation of an acoustic signal;
- an analog-to-digital converter for converting said electronic representation into a digital signal;
- a codec for producing a sequence of packets based on said digital signal;
- a decoder for converting a received sequence of packets into a digital stereo signal;
- a digital-to-analog converter for converting said digital stereo signal into a stereo analog signal suitable for transmission to a set of headphones;
- and
- a controller and Bluetooth transceiver arranged to:
- establish a Bluetooth paired connection with a device;
- establish an Advanced Audio Distribution Profile, A2DP, connection with the paired device to receive said sequence of packets for said decoder from said device;
- and
- establish a Serial Port Profile, SPP, connection with the paired device for simultaneously transmitting said produced sequence of packets based on said digital signal to said paired device as said received sequence of packets are being decoded for transmission to said set of headphones.
A Bluetooth microphone comprising:
- a transducer arranged to provide an electronic representation of a mono acoustic signal;
- an analog-to-digital converter for converting said electronic representation into a digital signal;
- a codec for producing a sequence of packets based on said digital signal;
- a decoder for converting a received sequence of packets into a digital stereo signal;
- a digital-to-analog converter for converting said digital stereo signal into a stereo analog signal suitable for transmission to a set of headphones;
- and
- a controller and Bluetooth transceiver arranged to:
- establish a Bluetooth paired connection with a device;
- establish a connection with the paired device to receive, from said device, said
- sequence of packets encoding said digital stereo signal for said decoder;
- and establish a connection with the paired device for simultaneously transmitting said produced sequence of packets based on said digital signal to said paired device as said received sequence of packets are being decoded for transmission to said set of headphones.
