► About PHiliphh Heartstart XL+ Defibrillator Louder Speaker Loudspeaker HB34 3W

The PHiliphh Heartstart XL+ defibrillator Louder Speaker is a transducer device that converts electrical signals into sound signals. The performance

of the speaker has a great impact on the sound quality.And you may be able to adjust the volume settings on the defibrillator to make the speaker

output louder. Additionally, using external speakers or headphones connected to the defibrillator may also help amplify the sound. It is important to

make sure that the speaker volume is loud enough to be heard clearly in emergency situations.

► The working principle of the speaker

First, an alternating current flows through the speaker coil. The moving coil generates an alternating magnetic field under the action of the input

current. The voice coil is placed on a permanent magnet. Under the action of these two magnetic fields, the moving coil moves perpendicular to

the current direction of the moving coil, so that the moving coil moves back and forth under the action of the current.

Since the moving coil is connected to the paper cone, the movement of the moving coil drives the front and rear vibrations of the paper cone. The

vibration of the paper cone drives the vibration of the air, and the human ear can sense the vibration of the air and produce sound. In this way, the

current input to the speaker is converted into sound through the action of the speaker.

The larger the alternating current input to the speaker, the larger the alternating current flowing through the voice coil, the stronger the magnetic

field, the greater the vibration amplitude of the speaker paper cone and the corresponding sound. On the contrary, when the alternating current

drawn by the speaker is less, the sound emitted by the speaker will be quieter.
