### Overview of AS07008PS-R The **AS07008PS-R** is a high-quality, miniature dynamic speaker manufactured by **PUI Audio**. It is part of the "AS" series, designed specifically for applications requiring a slim profile without compromising sound pressure levels. --- ### Technical Specifications The following table outlines the primary electronic and physical characteristics of the component: | Parameter | Value | | :--- | :--- | | **Impedance** | 8 Ohms (±15%) | | **Power Rating (Nominal)** | 0.5 Watts | | **Power Rating (Maximum)** | 1.0 Watt | | **Frequency Range** | 300 Hz ~ 20,000 Hz | | **Sound Pressure Level (SPL)** | 86 dB (±3dB) @ 0.5W/0.1M | | **Resonant Frequency (Fs)** | 500 Hz (±20%) | | **Dimensions** | 70mm x 30mm | | **Height/Depth** | 16.5 mm | | **Magnet Material** | Ferrite | --- ### Key Electronic Features 1. **Dynamic Driver Construction:** It utilizes a moving coil (voice coil) suspended in a magnetic field. When an AC signal passes through the coil, it interacts with the permanent ferrite magnet to move the diaphragm and produce sound. 2. **Wide Frequency Response:** With a range starting at 300 Hz and reaching up to 20 kHz, it is capable of reproducing clear human speech as well as higher-frequency alerts or music. 3. **Low Profile Design:** The rectangular shape (70mm x 30mm) is optimized for mounting in narrow enclosures, such as flat-screen monitors or handheld industrial devices. 4. **Paper Cone Material:** The use of a paper cone generally provides a "warm" and natural sound signature, though it is often treated to resist environmental moisture. --- ### Common Applications * **Industrial Equipment:** Control panels and audible status indicators. * **Consumer Electronics:** Flat-panel displays and smart home hubs. * **Security Systems:** Intercoms and alarm panels. * **Medical Devices:** Patient monitoring systems requiring audible alerts. --- ### Integration Notes ```markdown - **Polarity:** Ensure correct wiring (+/-) to maintain phase alignment, especially if using multiple speakers in a stereo or array configuration. - **Enclosure:** For optimal bass response (near the 300Hz-500Hz range), the speaker should be mounted in a sealed or ported enclosure to prevent acoustic short-circuiting. - **Driving Circuit:** Can be driven by standard Class D or Class AB audio amplifiers capable of handling an 8-ohm load at 1W. ```
