HOT 40mm 4 Ohm 5W Metal Frame Micro Mylar Speaker Full Range Small Micro Speaker Acoustic Component Loud Speaker

Mylar speakers are compact electro-acoustic components that use a thin Mylar (polyester film) diaphragm to generate sound. When an electrical signal passes through the voice coil, it interacts with a magnetic field, causing the lightweight diaphragm to vibrate and produce audio. Known for their slim profile, low weight, and stable performance, Mylar speakers are ideal for space-constrained designs. They typically offer clear mid-to-high frequency sound and moderate sound pressure levels. With good durability and cost efficiency, they are widely used in mobile devices, handheld electronics, and compact consumer products for voice and alert sound output.

Product Advantage

1. Ultra-Thin Design & Lightweight Structure

Mylar speakers use a polyester film diaphragm that enables an ultra-thin profile, often as slim as 2–4mm. This lightweight structure makes them ideal for compact and portable electronic devices where space is limited. Their reduced weight also contributes to easier integration and improved product design flexibility without compromising basic sound performance.

Product Operate Guide

When selecting a Mylar speaker, consider the rated power (e.g., 0.5W–2W) and impedance (commonly 4Ω or 8Ω) to ensure proper matching with your amplifier. Evaluate the frequency response (typically 500Hz–10kHz) for clear voice output, and confirm the ultra-thin size fits your product design. Also check sound pressure level for adequate volume and review durability and operating conditions to ensure stable performance and enhanced user experience.
