The Ultra-Thin Mini 8-Ohm 1-Watt Speaker is a specialized audio component designed for devices where internal space is at a premium. At Electrapac, we recommend this speaker for engineers and hobbyists building handheld gadgets, voice-prompt systems, and low-profile electronics.

Product Overview

With a diameter of only 36mm (3.6cm) and an incredibly slim profile, this speaker fits into the tightest enclosures. It is engineered to provide clear voice reproduction and notification tones without the bulk of traditional permanent magnet speakers.

Key Features for Electrapac Customers

• Ultra-Slim Profile: Designed specifically for modern, sleek enclosures. It can be easily tucked behind LCD screens or inside narrow plastic casings.

• Neodymium Magnet: Uses high-strength rare-earth magnets to produce significant volume and clarity despite its tiny size.

• 8-Ohm Standard: Compatible with almost all standard micro-amplifier chips, including the PAM8403 and the LM386, as well as direct output from some microcontrollers for simple tones.

• Durable Mylar/Plastic Cone: Unlike paper cones, the synthetic diaphragm used in this speaker is resistant to light moisture and humidity, ensuring longevity in portable devices.

• Solder-Friendly Terminals: Features small, easy-to-solder gold-plated or silver-colored pads for a secure connection to your project wires.

Project Integration Tips

To get the best performance for your project from www.electrapac.com, keep these tips in mind:

1. Acoustic Seal: For better sound quality, ensure the speaker is mounted firmly against the face of your enclosure. Using a small gasket or double-sided adhesive foam around the rim will prevent "sound leakage" and improve clarity.

2. Driving the Speaker: While 1W sounds small, it is very loud for close-range notifications. Use a 100uF capacitor in series if you are connecting it to a basic PWM output to prevent DC bias from overheating the voice coil.

3. Frequency Response: This speaker is optimized for mid-to-high frequencies (human voice, beeps, melodies). It is not designed for heavy bass music.

Primary Applications

• Handheld Instruments: Multimeters, scanners, and portable testers.

• Voice Announcers: Greeting cards, smart doorbells, and GPS navigation prompts.

• Robotics: Adding "speech" or sound effects to small robotic platforms.

• IoT Devices: Audible alerts for smart home sensors and alarm systems.
