Audio 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.
Distortion: Including harmonic distortion and intermodulation distortion, which directly affects the sound quality restoration.
3. What are Audio Products Used for?
Consumer electronics: Smart speakers, headphones, etc. rely on micro speakers and MEMS microphones to achieve high-fidelity interaction.
Professional audio: Floor-standing speaker systems with multi-frequency design meet the high dynamic requirements of theaters and recording studios.
Industrial equipment: Durable piezoelectric ceramics and buzzers are used in scenarios such as alarms and status prompts.
4. What are the Technology Development Trends of Audio Products?
Material innovation: Such as the application of laminated diaphragms and aerospace-grade aluminum materials to improve driver efficiency and durability.
Integrated design: The acoustic module integrates the microphone, speaker, and processing circuit to simplify the internal structure of the device.
