The **AS06004PS-R** is a high-performance, small-format speaker manufactured by **PUI Audio**. It is widely used in industrial equipment, medical devices, and consumer electronics where space is limited but clear audio output is required. --- ### 1. Technical Specifications The following table summarizes the key electrical and physical characteristics of the AS06004PS-R: | Parameter | Specification | | :--- | :--- | | **Manufacturer** | PUI Audio | | **Impedance** | 4 Ohms | | **Rated Power (RMS)** | 2.0 Watts | | **Maximum Power** | 3.0 Watts | | **Sound Pressure Level (SPL)** | 84 dB @ 1W / 0.5m | | **Resonant Frequency (Fs)** | 500 Hz | | **Frequency Range** | 500 Hz ~ 20,000 Hz | | **Dimensions** | 60mm x 60mm x 19mm | | **Weight** | ~23 grams | --- ### 2. Key Features * **Magnet Material:** It typically utilizes a high-energy **Neodymium (NdFeB)** magnet, which allows for a high power-to-weight ratio and a slim profile. * **Cone Material:** Usually features a treated paper or composite cone with a foam or cloth surround to balance durability and acoustic sensitivity. * **Frame Design:** Square-shaped frame with pre-drilled mounting holes for easy installation into enclosures. * **Connectivity:** Features solder pads for direct wire attachment. --- ### 3. Usage & Integration When integrating the AS06004PS-R into an electronic circuit, consider the following: #### Amplification Since it is a **4-Ohm** speaker, ensure your amplifier is rated for a 4-Ohm load. Using a 2W-5W Class-D amplifier chip (like the PAM8403) is a common choice for driving this component efficiently. #### Enclosure Design To achieve the best sound quality (especially at the lower end of its 500Hz range), the speaker should be mounted in a sealed or ported enclosure. Without an enclosure, "acoustic cancellation" occurs, where sound waves from the back of the speaker cancel out waves from the front, resulting in very thin sound. #### Polarity The speaker pads are marked with `+` and `-`. Maintaining correct polarity is crucial when using multiple speakers to ensure they are "in phase." ---
