| 摘要 |
<p>The present invention relates to a microphone arrangement 1 which has an SMD housing 6 with a sound inlet opening 7, a transducer 8 for receiving sound waves through the sound inlet opening 7 and for converting received sound waves into electrical signals, an analog-to-digital converter 10 for providing digital signals, an interface control unit 11 with a digital interface 2 which the arrangement 1 can use to transmit data serially to an external device 3, and at least one further interface 4 (also fig.5 â 12, 17 & 27) to which a peripheral device can be connected such that the at least one further interface can be used to transmit data between the peripheral devices and the interface control unit 11. The transducer 8, analog-to-digital converter 10, interface control unit 11 and the at least one further interface are integrated in the SMD housing (6). The peripheral device may be a combined input/output device 5, a remote control keypad of a headset(fig.6 - 18), speakers (fig.4 â 13 & 14) or a noise cancelling microphone (fig.5 â 30).</p> |
