There are many types of speakers and their prices vary greatly. Speakers can be divided into electric, electromagnetic, piezoelectric, etc. according to their structure. Among them, electric speakers are widely used in various audio equipment due to their good electroacoustic properties, solid structure and low cost.

Specifications

Speakers are divided into woofers, midrange speakers and tweeters according to their operating frequency.

The working principle of the loudspeaker: First, the alternating current is fed into the voice coil of the loudspeaker. The voice coil generates an alternating magnetic field under the action of the input current in the direction of the voice coil current, so that the voice coil makes a reciprocating motion under the action of the electric current.

Because the voice coil and the paper cone are connected, the movement of the voice coil drives the paper cone to vibrate back and forth. The vibration of the paper cone causes the air to vibrate, and the human ear can feel the vibration of the air and generate sound. In this way, the current input to the speaker is converted into sound by the action of the speaker.

When the AC input to the speaker is larger, the AC current flowing through the voice coil is also larger, and the stronger the magnetic field, the larger the vibration amplitude of the speaker cone and conversely the corresponding sound is louder The AC input to the speaker is: the smaller the current, the quieter the sound from the speaker.

The audio circuit uses an FM sound generator (sound source IC) to generate QRS sound, alarm sound, and key tone at the same time. The volume control data as well as the tone and pitch data are written to the FM sound generator by the host CPU. The audio output signal of the FM sound generator is amplified by the audio power amplifier to make the speaker sound.
