It is really a funny thing . It looks complicated that how does it work . Actually it is simple . There is a tiny motor inside the phone which has a D shape pendulam in its head . And when the motor runs it creats vibration .

Vibrating
TRUE
Ideally (as in, if things in science were perfect and all transfers of energy were completely transferable) no, sound is not necessarily made when matter vibrates. What do you mean by matter vibrating? like... atoms vibrating or chunks of ice vibrating or what?
A sound wave, like any other wave, is introduced into a medium by a vibrating object. The vibrating object is the source of the disturbance that moves through the medium. The vibrating object that creates the disturbance could be the vocal cords of a person, the vibrating string and sound board of a guitar or violin, the vibrating tines of a tuning fork, or the vibrating diaphragm of a radio speaker. Regardless of what vibrating object is creating the sound wave, the particles of the medium through which the sound moves is vibrating in a back and forth motion at a given frequency. The frequency of a wave refers to how often the particles of the medium vibrate when a wave passes through the medium. The frequency of a wave is measured as the number of complete back-and-forth vibrations of a particle of the medium per unit of time. If a particle of air undergoes 1000 longitudinal vibrations in 2 seconds, then the frequency of the wave would be 500 vibrations per second. A commonly used unit for frequency is the Hertz (abbreviated Hz), where 1 Hertz = 1 vibration/second As a sound wave moves through a medium, each particle of the medium vibrates at the same frequency. This is sensible since each particle vibrates due to the motion of its nearest neighbor. The first particle of the medium begins vibrating, at say 500 Hz, and begins to set the second particle into vibrational motion at the same frequency of 500 Hz. The second particle begins vibrating at 500 Hz and thus sets the third particle of the medium into vibrational motion at 500 Hz. The process continues throughout the medium; each particle vibrates at the same frequency. And of course the frequency at which each particle vibrates is the same as the frequency of the original source of the sound wave. Subsequently, a guitar string vibrating at 500 Hz will set the air particles in the room vibrating at the same frequency of 500 Hz, which carries a sound signal to the ear of a listener, which is detected as a 500 Hz sound wave.
The main differences between a xylophone, marimba, vibraphone, and glockenspiel lie in their sound and construction. The xylophone has wooden bars and a bright, sharp sound. The marimba has wooden bars as well, but they are larger and produce a warmer, mellower sound. The vibraphone has metal bars and a pedal mechanism that creates a vibrato effect, giving it a shimmering sound. The glockenspiel has metal bars like the vibraphone but is smaller and produces a bright, bell-like sound.
Vibrating produces sound.
sound energy is formed by a vibrating body. We can say that sound is produced only when a body is vibrating.

The vibraphone and glockenspiel are both percussion instruments, but they have differences in construction, sound production, and musical applications. The vibraphone has metal bars that produce a warm and mellow sound when struck with mallets, while the glockenspiel has smaller metal bars that produce a bright and clear sound. The vibraphone also has a motorized mechanism that creates a vibrato effect, while the glockenspiel does not. In terms of musical applications, the vibraphone is often used in jazz and contemporary music for its expressive capabilities, while the glockenspiel is commonly used in orchestral and marching band settings for its bright and piercing sound.
Not all vibrating objects produce sound. Sound is produced when a vibrating object creates compressional waves in a medium, such as air. If the vibrating object is not in contact with a medium that can carry sound, then no sound will be produced.
sound energy is formed by a vibrating body. We can say that sound is produced only when a body is vibrating.
The vibrating sound in a guitar is caused by the strings vibrating when they are plucked or strummed. This vibration creates sound waves that travel through the air and are amplified by the guitar's body and sound hole, producing the sound we hear.
The vibraphone, xylophone, and marimba are all percussion instruments, but they have key differences. The vibraphone has metal bars and a motor-driven vibrato mechanism, giving it a shimmering sound. The xylophone has wooden bars and a bright, sharp sound. The marimba has wooden bars like the xylophone but is larger and has a deeper, warmer sound. Playing techniques vary, with the vibraphone using a pedal for sustain, the xylophone played with hard mallets for a crisp sound, and the marimba using softer mallets for a rich tone.
