The horn is a very common supplies in life. The waterproof alarm speaker is responsible for protecting personal safety and property safety. So how does the waterproof alarm speaker speak?

The speaker is a device that converts the electricity into sound by electromagnetic induction. When different electronic energy is transmitted to the coil, the coil generates the energy interaction with the magnetic field, which causes the vibration of the paper tray. Electronic energy constantly changes, and the coil of the speaker will move forward or backwards. The paper plate of the speaker follows the movement to change the density of the air and generate sound.

At present, the most widely used speaker is a paper basin horn, also known as dynamic horn, that is, fixed magnets generate a constant magnetic field, coils in the magnetic field, and the coil is connected to the paper basin. When the coil has the audio current flowing through the coil, the change of the change of the coil produces vibration under the action of the constant magnetic field, causing the paper basin to vibrate. Because the coil is moving, it is called a dynamic ring.

The dynamic horn consists of three parts:

(1) Vibration system, including tapered paper basins, sound coils and constant films.

(2) Magnetic circuit system, including permanent magnets, magnetic conductors and field columns.

(3) Auxiliary systems, including racks, wiring boards, edges and dust cover. When the coil is in the magnetic field, the audio will change with the current magnetic field, and the magnetic field interacts with the permanent magnet, which makes the coil vibrate along the axial direction. Because of its simple structure, plump, soft sound, and width, the efficiency is low.

The above is the principle of the speaker's voice. If there are other questions about the waterproof alarm speaker, please contact us.
