描述
SMD microphone, also known as surface mount device microphone, is designed specifically for applications that focus on space. This type of microphone can be installed below the PCB (printed circuit board), allowing for minimal clearance between the product PCB and the casing.
Through the welding connection between the microphone and the customer PCB, it provides a unique technology for achieving acoustic sealing around the receiving hole, helping to reduce costs and simplify the mechanism and acoustic design.
In terms of performance, the zero height SMD microphone has high sensitivity (-42 dB rated sensitivity) at a power of 1 kHz, low output impedance (less than 100 ohms), and low total harmonic distortion (not exceeding 1%) at 100 dB SPL.
This design enables engineers to achieve true “zero additional height” on the upper end of the PCB.
In addition, this microphone is compatible with industry standard lead-free soldering technology and can be assembled using standard automated plug-in devices
This avoids the common manual assembly on the assembly line, bulky and expensive connecting equipment, as well as related testing and rework issues/costs associated with traditional capacitive microphones.
Overall, SMD microphones greatly simplify the production and assembly process while maintaining excellent performance, allowing the final product to reduce overall size or add more additional features.
Therefore, it has been widely used in modern electronic devices, such as mobile phones, tablets, laptops, and smart home devices
