Appearance


The speaker adopts a rectangular appearance design, and the diaphragm area has a special internal structure (such as anchor-like textures, etc.), which helps the vibration and diffusion of sound. It contains core sound-producing components such as a diaphragm, a voice coil, and a magnetic circuit. The voice coil drives the diaphragm to vibrate under the drive of electrical signals to produce sound. The outer rectangular frame is equipped with mounting holes to facilitate fixed installation with equipment or boxes, and there are wiring components on the side for connecting audio lines to transmit electrical signals.


Features


Electro-acoustic conversion: The core function is to efficiently convert the input electrical signal into a sound signal to achieve audio playback and restoration.

Space adaptation: The rectangular structural design enables it to better adapt to the internal space of small electronic devices and facilitate integration into various products.

Basic guarantee of sound quality: Within its designed audio frequency range, it can restore sound relatively clearly and stably, meeting general audio playback needs, such as voice prompts, simple music playback, etc.


Advantages


It is easy to install, and the mounting holes of the rectangular frame can be quickly fixed to the equipment, adapting to a variety of installation scenarios.

The rectangular shape can make better use of the internal space of the equipment and is suitable for integration into products with certain space constraints.

The internal texture design of the diaphragm helps improve the sound transmission effect, and the sound quality is relatively clear during low-power audio playback.


Instructions


When installing, use the mounting holes on the frame and use screws and other fasteners to firmly fix it on the device to prevent loosening due to vibration during use.

When wiring, you need to connect the audio lines according to the correct polarity to ensure normal electrical signal transmission to obtain good sound output.


Application Scenarios


It is widely used in small electronic equipment, such as portable radios, small multimedia speakers, children's toys (toys with sound functions), and sound prompt systems of some home appliances (such as sound prompt devices for microwave ovens, washing machines, etc.) to provide sound output functions for these devices.
