To know the principle of speaker sound, we first need to understand the way of sound transmission. The transmission of sound requires a medium (vacuum cannot transmit sound); the sound space must rely on all gases, liquids, and solids as media to spread out. These substances as the transmission media are called media. It is like a water wave. If you throw a stone on a calm water surface, there will be a wave on the surface of the water, and then it will travel from the opposite shore to 4 weeks; sound waves are formed in this way. The frequency of sound waves is in the range of 20-20,000 Hz, which can be heard by the human ear; below or above this range, the human ear cannot hear it. The propagation mode of wave and sound wave is the same, and the human ear can hear sound only through the propagation of the medium. Sound waves can propagate in gas, solid, and liquid.
Now let’s talk about the working principle of speakers. A horn is a device that converts electrical signals into acoustic signals. It is composed of coils, magnets, and paper cones. The current (alternating current) output by the amplifier moves the coil under the action of the magnetic field through the coil. The coil is connected to the paper cone to drive the paper cone to vibrate, and then the vibration of the paper cone pushes the air to produce sound.
When the horn receives the electrical signal output by the sound source device, the current will pass through the coil on the horn and produce a magnetic field response. The current passing through the coil is an alternating current, and its positive and negative poles are constantly changing; the positive and negative poles will attract each other when they meet, and the coil will move backward (in the box) when attracted by the magnet on the horn; the positive and positive poles will repel each other when they meet. , The coil moves outward (outside the box). This converging and expanding rhythm produces sound waves and airflow, and produces sound, which has the same effect as the vibration of our throat.
