    • Audio ProductsAudio Products 1. What are the Main Types of Audio Products? 1) Speaker Function: Converts audio electrical signals into sound energy output, and is the core component of the audio system. Technical features: Uses a pure piston drive design, combined with aluminum and damping materials to reduce distortion. Sensitivity, frequency response, and directional characteristics directly affect the sound quality. 2) Microphone Types: Including capacitive (ECM, MEMS) , dynamic, piezoelectric, etc. Application: Voice interaction, active noise reduction and recording scenarios, MEMS microphones have become the first choice for consumer devices due to their high consistency. Audio connector Structure: Divided into balanced, separate, and non-separate circuit designs, affecting anti-interference ability and signal transmission quality. Process requirements: The appearance must be free of burrs and leaks to ensure stability and durability. 3) Dynamic Unit Innovative technology: For example, the runway-type dynamic unit improves acoustic performance by optimizing the diaphragm material, which is suitable for professional microphones and micro speakers. 2. What are the Key Performance Parameters of Audio Products? ‌Nominal power and impedance‌: The speaker needs to match the rated power (such as 0.1W~200W) and impedance (4Ω~32Ω) to ensure compatibility‌. ‌Frequency response‌: Determines the audio coverage range, and high-end speakers can reach 23Hz~52kHz‌.…
      • MicrophonesMicrophones 1. Overview ‌ Microphone is a transducer device that converts sound wave signals into electrical signals. It is widely used in communication equipment, consumer electronics, medical instruments, and other fields. Its core function is based on the conversion of mechanical vibration caused by sound pressure changes and electrical parameters (such as capacitance and voltage) . ‌2. Classification and Working Principle ‌ 1) ‌Dynamic microphone ‌ Principle: Using electromagnetic induction, sound waves drive the diaphragm to drive the coil to move in the magnetic field, generating induced current. Features: Simple structure and durability, but low sensitivity, poor high-frequency response, suitable for human voice recording. 2) ‌Capacitive microphone ‌ Principle: Sound pressure causes the capacitance between the diaphragm and the backplate to change, and the bias voltage is provided by the charge pump. The signal is output after ASIC amplification. Subtypes: √‌MEMS microphone‌: The silicon-based diaphragm is etched using micro-electromechanical technology, and the ASIC chip is integrated. It has the characteristics of small size and good consistency. ‌ √‌Electret microphone ‌: The built-in electret material provides a fixed charge, and no external bias power supply is required. It is often used in consumer electronics products. ‌ 3) ‌Piezoelectric microphone‌ Principle: Utilize…
