Description

Overview

Miniature full-range cavity speakers in a range of frame sizes and impedance/power combinations, from 8Ω 1W up to 4Ω 3W. Each is a sealed-cavity (“BOX”) type speaker with a plastic frame and solder terminals, intended for embedding into small electronic products.

Specifications

  • Impedance / power options: 8Ω 1W, 8Ω 2W, 4Ω 2W, 4Ω 3W
  • Model codes follow frame size (e.g. 1318, 2112, 2030, 2415, 2828, 3516, 4020, 4230, 4330)
  • Type: full-range cavity speaker with enclosed back volume
  • Frame: plastic, with solder terminals marked + and −
  • Cone: composite diaphragm with surround

Purpose

The enclosed cavity is what makes these usable in thin devices: it traps the rear wave so the cone is not fighting the inside of the enclosure. Compared with an open thin speaker of the same size, the result is more output and usable low-frequency response from a very small part.

Applications

  • Smart home devices — voice assistants, doorbells, sensors
  • Small consumer electronics and handhelds
  • Toys, timers and alarm devices
  • Portable instruments and medical devices
  • Audio DIY projects

How to Use

  1. Match the impedance to your amplifier — a 4Ω speaker on an amplifier rated only for 8Ω will draw too much current.
  2. Choose the frame size that fits the available cavity, checking depth as well as footprint.
  3. Solder the leads observing the + and − markings so the speaker is in phase with any others.
  4. Seat the speaker so its front cavity is sealed against the grille opening; leaks around the frame cancel bass.
  5. Drive within the rated power (1W–3W depending on variant) to avoid distortion and diaphragm damage.
