发明名称 Wireless earphone with unidirectional and omnidirectional microphones
摘要 A wireless earphone (e.g., a Bluetooth earphone) is disclosed that includes a housing having a first hole and a second hole, a unidirectional microphone disposed rearward of the first hole; an omnidirectional microphone disposed rearward of the unidirectional microphone and under the second hole, and a mounting assembly in the housing for fastening the omnidirectional and unidirectional microphones. The earphone can substantially block out external noise and greatly reduce echo.
