As a sound output device, the speaker can convert electrical signals into sound to convey information. Its working principle is mainly related to vibration and resonance. When current passes through the coil of the horn, a magnetic field is generated, and the coil is forced to vibrate with the permanent magnet. This vibration will cause the membrane of the horn to also vibrate, and the vibration of the membrane will produce compression and rarefaction of air, thereby forming sound waves. When sound waves travel to the human ear, they become audible.
There are two types of speakers: long tube speakers and short tube speakers. The long tube speakers are more suitable for low-frequency sound output, and the short tube speakers are suitable for high-frequency sound output. The speaker can also be changed according to the requirements of sound performance, such as by adjusting parameters such as amplitude, frequency and phase to obtain different sound effects.
In general, although the working principle of the horn is simple, it plays an indispensable role. By converting electrical energy into sound energy, speakers allow us to enjoy clear, loud sounds that bring convenience and fun to our lives. At the same time, the working principle of the horn also inspires us to explore the field of knowledge such as acoustics and vibration, which provides important enlightenment for scientific research and technological development.
