Music Philately- Microphones on Stamps

-
A microphone colloquially called a mic or mike is an acoustic-to-electric transducer or sensor that converts sound into an electrical signal. In 1876, Emile Berliner invented the first microphone used as a telephone voice transmitter. Microphones are used in many applications such as telephones, tape recorders, karaoke systems, hearing aids, motion picture production, live and recorded audio engineering, FRS radios, megaphones, in 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 microphone), capacitance change (condenser microphone), piezoelectric generation, or light modulation to produce an electrical voltage signal from mechanical vibration. The sensitive transducer element of a microphone is called its element or capsule. A complete microphone also includes a housing, some means of bringing the signal from the element to other equipment, and often an electronic circuit to adapt the output of the capsule to the equipment being driven. Microphones are referred to by their transducer principle, such as condenser, dynamic, etc., and by their directional characteristics. Sometimes other characteristics such as diaphragm size, intended use or orientation of the principal sound input to the principal axis (end- or side-address) of the microphone are used to describe the microphone.

The TOPS ARTFEST 2024: Why The Cebu Community Should Not Miss It?  By Celso Duazo Pepito I was happy to graduate in Fine Arts in 1981 at the University of the Philippines Cebu . But for the next two to three decades of  my art practice, my journey as member of creative community were full of difficulties and challenges. In the 80's and 90's we had a very limited platforms for exhibition, thereby encouraging us to organize our exhibits in hotels , restaurants , malls , etc. Added to our problems is the limited art collectors in Cebu during that time. Attendees of exhibitions, more often than not were same people who have the heart for collecting artworks. And there were instances when these collectors will shy away from art exhibitions, with valid reasons that they do not have enough walls to hang their collections. With this problem in mind, few artists have opted to look for another job, if only to survive. There were few passionate painters, however, that opted to nurture the

The Will to Live 2021, ( Autostereogram )     When we look and appraise a painting by color blind Master artist Celso Duazo Pepito , one will immediately come face to face with a brilliantly made work of art.    He was born 54 years ago on the 22nd of November in Daan Bantayan , Cebu . He plunged into the world of art as a young man who showed special skills in lettering . He was surprised when he steps into the halls of the University of the Philippines that the fine arts course was after all about painting. His painting career soon took off soon after college.    There were years of facing struggles hurdling one trial after another. But, like college education, experience is considered as the best teacher. His paintings are known to contain imagery that is brought to life by crisp and clear lines, bold strokes and his usual usage of bright color scheming. But deep within his subjects are personal motives and intentions that come from his heart. The man is with a mission he
