Patent number: 11284187Abstract: A small-array MEMS (micro-electro mechanical system) microphone apparatus is provided. The apparatus includes first and second microphone modules. A first microphone of the first microphone module captures a first acoustic signal from a sound source through a first acoustic hole. A second microphone of the second microphone module captures a second acoustic signal from the sound source through a second acoustic hole. A first integrated circuit performs a first logic operation on the first acoustic signal and the second acoustic signal to generate a first sum acoustic signal. The first integrated circuit performs a sampling delay on the second acoustic signal with a first clock signal, and subtracts the delayed second acoustic signal from the first acoustic signal to obtain a first differential acoustic signal. The first differential acoustic signal has a first directivity. A second integrated circuit bypasses and outputs the second acoustic signal which is omnidirectional.Type: GrantFiled: October 26, 2020Date of Patent: March 22, 2022Assignee: FORTEMEDIA, INC.Inventors: Yen-Son Paul Huang, Tsung-Lung Yang

Patent number: 7894620Abstract: A mobile phone and an acoustic box structure thereof are provided. The mobile phone includes a shell containing a printed circuit board (PCB) and a hidden antenna therein. The acoustic box structure is disposed between the PCB and the hidden antenna. The acoustic box structure includes a main body, a loudspeaker accommodated in the main body and a frame located between the PCB and the main body. Due to the design of the frame, a hermetic space is framed between the PCB and the main body, thereby preventing sound waves generated by the loudspeaker from leaking out via a gap between the main body and the PCB. Furthermore, the frame made of shockproof materials decreases the resonant transfer between the PCB and the loudspeaker. Consequently, the quality of the sound made by the mobile phone is improved.Type: GrantFiled: November 8, 2006Date of Patent: February 22, 2011Assignee: Foxconn Technology Co., Ltd.Inventor: Tsung-Lung Yang
