Description
Technical field
The utility model relates to sound technique field, particularly relates to a kind of Bluetooth speaker system supporting NFC.
Background technology
Sound equipment refers to other sounds except the language of people, music, comprises the sound of natural environment, various sound etc. that the sound of animal, the sound equipment of machine tools, the action of people send.Sound equipment probably comprises power amplifier, peripheral equipment (comprising compressor, effect device, equalizer, VCD, DVD etc.), loud speaker (audio amplifier, loudspeaker) sound console, microphone, display device etc. and adds up a set of.Wherein, audio amplifier is exactly audio output device, loudspeaker, subwoofer etc.
USB is the abbreviation of English Universal Serial Bus (USB), and its Chinese is referred to as " logical get lines crossed ", is an external bus standard, for connection and the communication of specification computer and external equipment.It is the interfacing being applied in PC field.Coaxial SPDIF is commonly referred to as coaxial input, and the backboard of equipment has COAXIAL to make a check mark.Numeral coaxial interface employing impedance is the coaxial cable of 75 Ω is transmission medium, and its advantage is constant impedance, and transmission band is wider, and the coaxial cable frequency range of high-quality can reach hundreds of megahertz.The time base error of numeral coaxial transmission is very little, and therefore this transmission means has good performance to tonequality.
Near-field communication (Near Field Communication, NFC), also known as wireless near field communication, be a kind of short-range high frequency wireless communication technology, allow to carry out contactless Point-to-Point Data Transmission (in ten centimetres) swap data between electronic equipment.This technology is developed by contact-free formula radio-frequency (RF) identification (RFID), and backward compatible RFID, succeeded in developing by Sony and Philips the earliest, be mainly used in the handheld devices such as mobile phone, providing the M2M communication of (Machineto Machine).Because near-field communication has natural fail safe, therefore, NFC technique is considered to have great application prospect in fields such as mobile-phone payments.
NFC and bluetooth (Bluetooth) are all short-range communication technology, and NFC can simplify bluetooth and connect.The place that NFC is slightly better than bluetooth is that setting program is shorter, but cannot reach the speed of low-power bluetooth (Bluetooth Low Energy).In two interconnective recognition of devices processes of NFC device, use NFC to substitute and the speed that establishment can be made to connect manually is set greatly accelerates: be less than 1/10th seconds.The largest data transfer amount 424kbit/s of NFC is much smaller than BluetoothV2.1 (2.1Mbit/s).Although NFC less than bluetooth (being less than 20cm), corresponding can reduce unnecessary interference in transmission speed and distance.This allow NFC be specially adapted to equipment intensive and transmission become difficulty time.Relative to bluetooth, NFC is compatible with existing passive RFID (13.56MHz ISO/IEC 18000-3) facility.The energy requirement of NFC is lower, similar with bluetooth V4.0 low power consumption protocol.When NFC works on a motorless equipment (mobile phone of a such as shutdown, contactless smart credit card, or smart poster), the energy ezpenditure of NFC is less than low-power consumption bluetooth V4.0.For mobile phone or mobile consumption electronic products, the use of NFC is more convenient.Short haul connection characteristic its advantage just of NFC, because power consumption is low, once only and a machine link, has higher confidentiality and fail safe, avoids stolen when NFC is conducive to credit card trade.The target of NFC is not replace other wireless technologys such as bluetooth, but plays in different occasions, different fields the effect mutually supplemented.
At present along with the fast development of audio, video data, the application of various complex environment faced by sound system needs and change, existing sound system cannot be satisfied with the compatibility such as NFC, Bluetooth technology, cannot be satisfied with the control etc. under application scenarios.
