Sound is one of the most common and substantial forms of energy that envelops our daily lives. Sound is a product of mechanical waves that trigger an object's natural frequency. This natural frequency sends out vibrating waves that we hear as sound. In order to better understand mechanical waves and electrical impulses, you must first be able to understand the properties of waves, speakers, and electrical signals. Waves are a crucial key element in understanding sound. There are two types of mechanical waves, longitudinal and transverse. In both waves, the particles must move with the medium. A medium is the type of object or material that carries energy through a field. In longitudinal waves, particles move in a parallel direction. An example of a longitudinal wave would be a slinky or ultrasonic machine. Now a transverse wave is a wave that moves horizontally. An example of this wave would be any type of electromagnetic wave. Like radio or light waves. There are three main properties you need to know to understand waves. The first major property is wavelength. Wavelength is the distance between two points on a wave. The next major property is amplitude. Amplitude is measured by the height of the wave. The higher the wave, the stronger the wave signal. The last property you need to know is frequency. Frequency is the number of times a wavelength transpires in a second. Frequency is measured in kilohertz but is commonly interpreted as height. A high tone requires a high frequency, just as a low tone requires a low frequency. However, what you really need to know about how sound waves work is pressure. Without pressure, sound would not exist. The pressure is essentially two t...... middle of paper ......o generate an alternating magnetic field. This alternating field is the driving force that causes the cone to repel. The coil receives many different pulse ranges which can cause the cone to move very violently, if at all. The next major component of a speaker is the suspension. Suspension is what forces the cone to return after being pushed back by pressure. Suspension also plays a major role in preventing the reel from mutilating itself. If the coil were to be mutilated, the cone would no longer be able to function. The final component of a speaker is the cone. The cone essentially regulates the amount of air that can be expelled from the speaker. The more air there is, the greater the mass and efficiency of the enclosure will be. The speakers are equipped with a mount capable of capturing the power of the signal and making it louder. This part is known as the amplifier.
