Appearance
Front (1st picture): The main body is a smooth black round diaphragm, used for sound production. The periphery of the diaphragm is an integrated black plastic frame, and the overall design is simple and compact.
Side and back (2nd picture): Shows the thickness of the speaker and installation details. There is a metal bracket on the bottom with two screw mounting holes. The bracket material or related parts are marked with HDPE (high-density polyethylene), which is a durable engineering plastic. Metal brackets ensure stable installation.
Features
Core Voicing: Convert electrical signals into sound.
Compact design: Small diameter of 33mm, ideal for applications with strict space requirements.
Easy to install: Special metal brackets and mounting holes make it easy to quickly and securely fix it to the equipment panel or cavity.
Lightweight and durable: The overall structure is lightweight, and the HDPE material components have a certain degree of strength and chemical resistance.
Advantages
High space efficiency: extremely small diameter, can be installed in very small spaces.
Sturdy installation: The metal bracket provides reliable mechanical support and resists vibration.
Easy integration: Standard installation method, easy for production and assembly.
Instructions
Installation and fixation: Align the metal bracket of the speaker with the installation position inside the device, and use screws to pass through the two holes on the bracket to lock it.
Circuit connection: Solder the audio cable to the terminal of the speaker (not directly shown in the picture, usually located on the back of the diaphragm or the lead pin). Be sure to pay attention to polarity.
Drive matching: Use a power-matched audio amplifier circuit for driving.
Application Scenarios
Portable consumer electronics: ultra-thin Bluetooth speakers, headphones (for reminder sounds), wearable devices.
Security and sensing equipment: Micro smoke alarms, door sensors, and sound units for Internet of Things (IoT) sensors.
Precision instruments: Status prompt sound units for medical equipment and measuring instruments.
Communication equipment: mini walkie-talkies, telephone receivers.
Advanced toy models: Exquisite models that require built-in sound generation functions.
