Appearance


Front (corresponding to the description in the first picture): The main body of the speaker is round. The core is a black diaphragm, surrounded by a wide black rubber suspension, providing good compliance. The outermost layer is a sturdy black metal basin frame with a circular mounting hole at each corner to ensure stable installation. Two white dedicated terminal blocks protrude from both sides of the basin frame for quick plug-in connections.

Backside/close-up (corresponding to the description in the second picture): shows the internal structure of the unit. In the center is a silver-gray internal magnetic circuit system (magnet), which is compact and can effectively prevent magnetic field leakage from interfering with peripheral circuits. Above the magnetic circuit is the voice coil. In addition, there are two small metal pins on the bottom that can be soldered directly to the circuit board (PCB).


Features


Dual connection mode: You can quickly connect through the white terminals on the side, or use the metal pins on the bottom for PCB welding. The integration method is very flexible.

Internal magnetic design: The magnetic circuit is completely wrapped and the magnetic field leakage is small. It is suitable for installation near monitors, disks and other devices that are sensitive to magnetic fields.

Robust construction: Metal basin frame and rubber rims ensure durability and stability of the unit.

Efficient sound generation: Dynamic coil design provides clear sound.


Advantages


Flexible connection: Provides two options of plugging and welding, adapting to different scenarios such as R&D, testing and mass production.

Firm installation: Metal basin frame and four-corner mounting holes have good vibration resistance.

Strong compatibility: The internal magnetic design makes it safe to use in a variety of electronic environments without worrying about magnetic interference.


Instructions


Installation and fixation: Place the speaker into the opening of the equipment panel, and use screws to lock it through the mounting holes at the four corners of the basin frame.


Application Scenarios


Multimedia devices: computer monitors, portable televisions, radios with built-in speakers.

Office equipment: Prompt sound units for fax machines and attendance machines.

Security equipment: Sounders for building intercoms and access control systems.

Consumer electronics: electronic toys, smart home equipment sound speakers.

Industrial control: Industrial instruments and control panel alarms.
