Please answer the following question: Information: - A personal computer (PC) is a multi-purpose electronic computer whose size, capabilities, and price make it feasible for individual use. PCs are intended to be operated directly by a person using a graphical user interface such as Windows. The versatility of a personal computer is greatly enhanced by the use of peripheral devices such as a keyboard, monitor, printer, mouse, speakers, and an external hard drive. - A video game console is an electronic, digital or computer device that outputs a video signal or visual image to display a video game that one or more people can play. - Headphones (or head-phones in the early days of telephony and radio) are a pair of small listening devices that are designed to be worn on or around the head over a user's ears. They are electroacoustic transducers, which convert an electrical signal to a corresponding sound in the user's ear. Headphones are designed to allow a single user to listen to an audio source privately, in contrast to a loudspeaker, which emits sound into the open air, for anyone nearby to hear. Headphones are also known as earspeakers, earphones or, colloquially, cans. Circumaural and supra-aural headphones use a band over the top of the head to hold the speakers in place. The other type, known as earbuds or earphones consist of individual units that plug into the user's ear canal. In the context of telecommunication, a headset is a combination of headphone and microphone. Headphones connect to a signal source such as an audio amplifier, radio, CD player, portable media player, mobile phone, video game console, or electronic musical instrument, either directly using a cord, or using wireless technology such as bluetooth or FM radio. The first headphones were developed in the late 1800s from telephone receivers for use by telephone operators, to keep their hands free. Initially the audio quality was mediocre and a step forward was the invention of high fidelity headphones. - BBBeat is an audio game designed for the visually impaired . As such it has no video display . The player wears a pair of headphones and must use sound to locate a bee and then swat it . Sensors attached to the wrist indicate whether or not the '' bee '' was swatted . The game was developed by Makato Ohuchi at Tohoku Fukushi University in Japan . The game is designed for schools and rehabilitation centers for blind people , to assist with sound location and learning to navigate base on sound source , not for personal entertainment . The game requires extensive hardware , and is expected to cost in the thousands of US dollars . - A mobile phone is a portable telephone that can make and receive calls over a radio frequency link while the user is moving within a telephone service area. The radio frequency link establishes a connection to the switching systems of a mobile phone operator, which provides access to the public switched telephone network (PSTN). Most modern mobile telephone services use a cellular network architecture, and therefore mobile telephones are often also called "cellular telephones" or "cell phones". In addition to telephony, 2000s-era mobile phones support a variety of other services, such as text messaging, MMS, email, Internet access, short-range wireless communications (infrared, Bluetooth), business applications, gaming, and digital photography. Mobile phones which offer these and more general computing capabilities are referred to as smartphones. - An audio game is an electronic game played on a device such as a personal computer. It is similar to a video game save that there is audible and tactile feedback but not visual. - A portable media player (PMP) or digital audio player (DAP) is a portable consumer electronics device capable of storing and playing digital media such as audio, images, and video files. The data is typically stored on a CD, DVD, flash memory, microdrive, or hard drive. Most portable media players are equipped with a 3.5mm headphone jack, which users can plug headphones into, or connect to a boombox or hifi system. In contrast, analog portable audio players play music from non-digital media that use analog signal storage, such as cassette tapes or vinyl records. - A loudspeaker (or loud-speaker or speaker) is an electroacoustic transducer; which converts an electrical audio signal into a corresponding sound. The most widely used type of speaker in the 2010s is the dynamic speaker, invented in 1925 by Edward W. Kellogg and Chester W. Rice. The dynamic speaker operates on the same basic principle as a dynamic microphone, but in reverse, to produce sound from an electrical signal. When an alternating current electrical audio signal is applied to its voice coil, a coil of wire suspended in a circular gap between the poles of a permanent magnet, the coil is forced to move rapidly back and forth due to Faraday's law of induction, which causes a diaphragm (usually conically shaped) attached to the coil to move back and forth, pushing on the air to create sound waves. Besides this most common method, there are several alternative technologies that can be used to convert an electrical signal into sound. The sound source (e.g., a sound recording or a microphone) must be amplified or strengthened with an audio power amplifier before the signal is sent to the speaker. - An electronic game is a game that employs electronics to create an interactive system with which a player can play. Video game is the most common form today, and for this reason the terms are often mistakenly used synonymously. Other common forms of electronic game include such products as handheld electronic games, standalone systems (e.g. pinball, slot machines, or electro-mechanical arcade games), and exclusively non-visual products (e.g. audio games). After reading the paragraphs above, we are interested in knowing the entity with which 'bbbeat' exhibits the relationship of 'platform'. Find the answer from the choices below. Choices: - basic - dvd - handheld - internet - mobile phone - personal computer - video game console - windows
