A microphone, colloquially mic or mike (/ˈmaɪk/), is an acoustic-to-electric transducer or sensor that converts sound into an electrical signal. Electromagnetic transducers facilitate the conversion of acoustic signals into electrical signals. Microphones are used in many applications such as telephones, hearing aids, public address systems for concert halls and public events, motion picture production, live and recorded audio engineering, two-way radios, megaphones, radio and television broadcasting, and in computers for recording voice, speech recognition, VoIP, and for non-acoustic purposes such as ultrasonic checking or knock sensors.
Most microphones today use electromagnetic induction (dynamic microphones), capacitance change (condenser microphones) or piezoelectricity (piezoelectric microphones) to produce an electrical signal from air pressure variations. Microphones typically need to be connected to a preamplifier before the signal can be amplified with an audio power amplifier and a speaker or recorded.
Idrissa Akuna "Idris" Elba, OBE (/ˈɪdrəs ˈɛlbə/; born 6 September 1972) is a British actor, musician, and DJ. He is best known for his portrayal of drug lord and aspiring businessman Russell "Stringer" Bell in the HBO series The Wire, Detective John Luther in the BBC One series Luther, and Nelson Mandela in the 2013 biographical film Mandela: Long Walk to Freedom. He has been nominated five times for a Golden Globe Award for Best Actor in a Miniseries or Television Film, winning one, as well being nominated four times for a Primetime Emmy Award.
Elba has appeared in films such as American Gangster (2007), Takers (2010), Thor (2011), Prometheus (2012), Pacific Rim (2013), Thor: The Dark World (2013), and Beasts of No Nation (2015). In addition to his acting work, he is a DJ under the moniker DJ Big Driis (or Big Driis the Londoner) and hip hop soul musician.
Elba was born in Newham, London. His father, Winston, was a Sierra Leonean who worked in a Dagenham Ford motor factory, and his mother, Eve, was a Ghanaian who had a clerical job. Elba's parents married in Sierra Leone and moved to London. Elba was raised in East Ham and shortened his first name from Idrissa to Idris at school in Canning Town, where he first became involved in acting. He credits The Stage with giving him his first big break; having seen an advertisement for a play in the newspaper, Elba auditioned and met his first agent while performing in the role. In 1986, he began helping an uncle with his wedding DJ business; within a year, he had started his own DJ company with some of his friends.
You tore a hole so deep my leak poured out torrentially
But now I'm bored
My bloody flow is slowed so I can be bored near you
Oh, what a loss
It didn't show its head until mine was torn and thrown at you
And back it grew
With glassy eyes walked and contact on the couch with you
Oh, boring face
We're losing touch I reached and my extended hand went through
Now we both know what we have to do
