Microphone assembly with mems motor and integrated circuit
A recently granted patent (Publication Number: US11968487B2) discloses a microphone assembly designed with a form-factor adapter housing that includes an interface opening and an outer acoustic port. The internal microphone assembly within the housing consists of an internal housing with an internal acoustic port, a microelectromechanical systems (MEMS) motor, an integrated circuit, and electrical interface contacts. The adapter interface at the interface opening connects to external host device interface contacts, allowing the MEMS motor to be acoustically coupled to the outer acoustic port through a sound path within the housing.
Furthermore, the patent details variations in the design of the microphone assembly, such as the use of a printed circuit board (PCB) for the adapter interface, changes in the order of electrical connections between internal and host device interface contacts, and the positioning of the MEMS motor and integrated circuit within the internal housing. The assembly also features an external acoustic port on the form-factor adapter housing, allowing for acoustic coupling with the internal acoustic port. These innovative features aim to enhance the performance and functionality of the microphone assembly, providing improved sound quality and versatility for various applications.
