The **AS07008PO-2-R** is a high-quality, miniature loudspeaker manufactured by **PUI Audio**. It is specifically designed for applications where high fidelity and slim profiles are required, such as in telecommunications, medical devices, or portable electronics. --- ### 1. Key Technical Specifications The following table highlights the primary electrical and physical characteristics of the component: | Feature | Specification | | :--- | :--- | | **Type** | Dynamic Speaker (Moving Coil) | | **Impedance** | 8 Ohms (±15%) | | **Power Rating** | 2 Watts (Nominal) / 3 Watts (Maximum) | | **Sound Pressure Level (SPL)** | 84 dB @ 1W/0.5m | | **Frequency Range** | 300 Hz – 20,000 Hz | | **Resonant Frequency (Fs)** | 300 Hz (±20%) | | **Magnet Material** | NdFeB (Neodymium) | | **Weight** | ~24 grams | --- ### 2. Component Construction The AS07008PO-2-R utilizes advanced materials to achieve high performance in a small footprint: * **Neodymium Magnet:** Provides a high magnetic flux density, allowing the speaker to be powerful yet lightweight. * **Paper Cone / Cloth Surround:** The choice of cone material balances durability with natural sound reproduction. * **Frame Material:** Typically constructed from steel with a black electro-deposition coating to prevent corrosion. * **Termination:** Features solder pads for secure electrical connection to a PCB or wiring harness. --- ### 3. Usage and Implementation When integrating this part into a circuit, consider the following electronic principles: #### Power Management Since the nominal power is **2 Watts**, your amplifier circuit should ideally be capable of delivering this wattage at 8 Ohms without clipping. * **Safe Voltage:** $V = \sqrt{P \times R} \approx 4.0V$ RMS. #### Enclosure Design To prevent "acoustic short-circuiting" (where the front wave cancels the back wave), this speaker must be mounted in a sealed or ported baffle. Because the Resonant Frequency ($F_s$) is 300 Hz, it is not suitable for deep bass but excels in voice and mid-range frequencies. #### Polarity The speaker features a positive (+) and negative (-) terminal. Correct phasing is critical if using multiple speakers to ensure they move in synchronization. ---
