Shrapnel Horn 15*11mm 16*09mm Aluminum Film Shrapnel Square Magnetic Speaker 8Ω 1W For Smartwatch Cell Phone Speakers 1511/1609

Description

Overview

Miniature rectangular “shrapnel” speaker with an aluminium film diaphragm and a sealed plastic cavity. It is a surface-mount device: the gold solder pads are reflow-soldered directly onto the PCB, and a foam ring seals the assembly against the enclosure to prevent sound leakage.

Specifications

Impedance and power: 8Ω, 1W rated
Available sizes: 15 × 11mm / 16 × 9mm
Type: enclosed BOX cavity micro speaker, rectangular
Diaphragm: aluminium film shrapnel type
Mounting: SMD solder pads for PCB reflow soldering
Sealing: supplied with a foam dust-proof / anti-leak ring
Housing: black plastic sealed sound cavity

Purpose

Because the diaphragm is backed by a closed cavity, this speaker produces noticeably more volume and better low-frequency response than an open thin speaker of the same size. The SMD pads mean it can be placed by pick-and-place machines and reflowed with the rest of the board, which suits volume production.

Applications

Smart wearables — smart watches and wristbands
Bluetooth earphone charging cases
Handheld terminals — barcode scanners, PDAs, industrial detectors
Smart home — door locks, alarms, motion sensors, control panels
Small appliances — electric toothbrushes, beauty devices, humidifiers
Consumer electronics — handheld games, toys, mini players
Automotive accessories — tyre pressure monitors, alarm modules

How to Use

Choose the size that fits the acoustic chamber in your enclosure — 15 × 11mm or 16 × 9mm.
Place the speaker on the PCB pads and reflow-solder it as part of the normal SMT process.
Fit the foam sealing ring around the frame so the front cavity is isolated from the rear volume.
Make sure the enclosure opening in front of the diaphragm is not blocked and is large enough not to strangle the output.
Drive it within the 1W rating; excessive power will distort and eventually damage the diaphragm.

✅ Product Use
This is a * * BOX cavity miniature speaker * *, designed to provide audio output for small electronic products:
1. Play voice prompts, alarm sounds, ringtones, and simple audio;
2. Closed sound chamber design, compared to ordinary thin speakers, with higher volume and better bass;
