| 发明名称 | Microphone apparatus and method for removing unwanted sounds | ||
| 摘要 | An apparatus comprises a first transducer configured to detect sound and generate a first signal based on the detected sound. The apparatus also comprises a second transducer configured to detect vibration and/or sound and generate a second signal based on the detected vibrations and/or sound. The second transducer is less acoustically responsive than the first transducer. The apparatus comprises an interface configured to send the first and second signals to a processor configured to modify the first signal on the basis of the second signal. | ||

| 主权项 | 1. An apparatus comprising an audio module configured to capture sound, the audio module comprising: a first membrane configured to detect sound and generate a first signal based on the detected sound; anda second membrane configured to detect vibration and/or sound and generate a second signal based on the detected vibration and/or sound, the second membrane being less acoustically responsive than the first membrane; andan interface configured to send the first and second signals to a processor configured to modify the first signal on the basis of the second signal so as to remove unwanted vibrations and/or sounds from the first signal;wherein the first membrane and the second membrane are disposed adjacent to each other on a same substrate. | ||
