ABSTRACT OF THEPATENT EXPLORATION • This invention discloses a digital wirelessspeaker system for use in consumer audioapplications. • A digital radio frequency transmitter is connectedto an analog or digital audio source and a digital radio frequency receiver provides for reception of the transmitted audio information in remotelocations.
WIRELESS BLUETOOTH SPEAKERS • Wireless speakers are loudspeakers which receiveaudio signals using radio frequency (RF) waves rather than over audiocables.
INTRODUCTION • The development of the wireless speaker roughly coincided with the development of Bluetooth technology. • Bluetooth technology was created by the Ericsson company as a wireless alternative to datacables. • Basically, Bluetooth transports data usingradio signals. • The difference between Bluetooth and other wireless devices that use radio waves isdistance. • Bluetooth broadcasts over a much smaller area than things like mobile phones and televisionbroadcasts.
Bluetooth wireless connectivity is easy to implement and canhelp you achieve mass market adoption. • Backed by a proven record of market creation, technology innovation andglobal leadership, Bluetooth sets the standard for wirelessconnectivity.
PRINCIPLES • A fundamental strength of Bluetooth wireless technology is the ability to simultaneouslyhandle data and voicetransmissions. • Innovative solutions such as hands-free headsetsfor voice calls, printing and fax capabilities, and synchronization for PCs and mobile phones, just to name afew.
APPLICATIONS • Cordless Devices: All (or most) of theperipheral devices (e.g., mouse, keyboard, printer, speakers, etc.) are connected to the PC cordlessly. • Ultimate headset: It can be used to allow one headset to be used with myriad devices, including telephones, portable computers, stereos,etc.
Advantages of BluetoothTechnology • It removes the problem of radio interference by using a technique called Speed Frequency Hopping.Easy topair. • The power consumption of the chip (consisting of transceiver) is low, at about 0.3mW, which makes it possible for least utilization of battery life. • This implies the transmitters change frequencies 1,600 times every second, meaning that more devices can make full use of a limited slice of the radiospectrum.
CONCLUSION • Bluetooth speakers are perfect if you want to listen to music while outdoors. If you want to catch up on your favorite songs while on a picnic, in a park, or on a camping trip, these are idealinvestments. • However, for home use, you may want to look at other wireless speakers that can deliver more power and better soundquality.
CHALLENGES • Reconnect your Bluetooth device to the speaker adapter if you've recently deactivated Bluetooth on the device, because after Bluetooth is enabled, it won't reconnect with the speakerautomatically. • Go over the settings on your device and confirm they're set up to stream overBluetooth.
FUTURESCOPE: • Bluetooth Technology needs some revolutionbecause Wi-Fi direct technology serves the same purpose and is several times faster thanBluetooth. • The benefit of Bluetooth is the low power consumption, low cost and the fact that it is a widely used standard. Some clever uses like Bluetooth tags to locate items, check it’s movement, cloths that can communicate via BT, more BT accessories that we could use in our everyday life, payment systems, wireless automated printing,etc.
