Description

The invention relates to a wireless headphone with vibration function, in particular using a wireless bluetooth headphone Vibration function, which is radio-controlled together with a cell phone is used.

Bluetooth is a protocol for wireless Data transfer. The standard is used for data transmission thanks to short-wave radio with a short range. The connection type is one-to-one. In addition to a data channel, voice channels are also available. By this procedure is intended to make wired data transmission superfluous. Let it through wireless local area networks or data transmission between mobile and stationary devices enable. there the data exchange can also take place automatically as soon as the range is undercut. An example would be the automatic data comparison between the mobile devices with networking in the private sector. To be bluetooth capable, must they equipment equipped with the Bluetooth chip for transmission and reception control be, but can also be retrofitted for older devices should. With Bluetooth technology, various Bluetooth products can be developed, e.g. a wireless bluetooth headphone, one portable cell phone watch and a radio portable on a finger. With such devices you can now watch internet data and send and receive the "e-mail" messages.

Various wireless are currently available Bluetooth headphones commercially available mostly for the use is developed together with a cell phone. through The Bluetooth technology can either be from a Bluetooth cell phone transmitted Singal wirelessly to a Bluetooth headset become or a transferable Signal through a Bluetooth headset wirelessly to a Bluetooth cell phone be sent to achieve the goal of full duplex data transmission. There a wireless bluetooth headphone Often, it is easy to carry and can be used separately from a cell phone his cell phone somewhere nearby and carries you only have your own Bluetooth headphones. Because the one generated by a bluetooth headphone Warning voice is pretty weak and you get this incoming call voice because of the strange strong interference caused by disturbing noises, you can often ignore them an incoming call.

The present invention was made under consideration the above circumstances created. The invention makes a wireless headphone with a vibration function while of an incoming call, which headphones are one Has oscillator and by processing an incoming call signal can control the transducer to indicate an incoming call signal.

This is essentially due to the Characteristics achieved in the main claim.

A main feature of the wireless according to the invention Bluetooth headset consists of a wireless communication module to receive an incoming one Call signal and a digital signal processor for processing an incoming call signal to drive a drive circuit, which is a drive signal for can generate a vibrator to indicate an incoming call signal.

Advantageous further developments of Invention result from the subclaims.

The invention is illustrated below an advantageous embodiment with reference to the attached Drawings described for example. Show it:

l is a schematic representation of a preferred embodiment of a wireless Bluetooth headphone according to the invention to show a wireless full-duplex data transmission between it and a cell phone.

2 a circuit diagram of a preferred embodiment of a wireless Bluetooth headphone according to the invention.

A preferred embodiment of the Bluetooth headphones 10 according to the invention as in 1 is shown can either be from a bluetooth cell phone 30 received signal received wirelessly or a signal to a Bluetooth cell phone 30 send wirelessly. By switching one on and off on the Bluetooth headphones 10 trained switch 13 can the vibration function of a wireless Bluetooth headphone according to the invention 10 are preferably actuated to display an incoming call signal.

Like this in the 2 is shown, the wireless Bluetooth headset 10 generally, according to one embodiment of the present invention, a wireless telecommunications module 11 , a digital signal processor 12 , a switch 13 , a drive circuit 14 , a transducer 15 , an acoustic data transmission, coding and decoding device 16 , headphones 17 and a microphone 18 on, with the transducer 15 can advantageously be controlled by processing a call signal in order to clearly display an incoming call signal.

How out 2 can be seen, the wireless telecommunications module 11 to the digital signal processor 12 be connected to a radio controlled acoustic signal 20 to receive and a modulated response signal 22 to send, the radio-controlled acoustic signal 20 is an incoming call signal. That of wireless telecommunication module 11 Received acoustic call signal is first through the digital signal processor 12 processed to provide a control signal to the drive circuit 14 to generate a drive signal and thereby output the transducer 15 to be controlled so that an incoming call signal can be displayed. The drive circuit 14 is a transistor drive circuit made from a transistor and a resistor. The base of the transistor is through the resistor to the digital signal processor 12 connected for control purposes so that the oscillator connected to the emitter of the transistor 15 the driven signal can oscillate either briefly or continuously. At the same time, the wireless communication module 11 the radio-controlled acoustic signal 20 to the digital signal processor 12 send for processing purpose, causing this acoustic signal 20 further from the digital signal processor 12 built-in acoustic data transmission, coding and decoding device 16 is decoded and by the bluetooth headphones 17 is transmitted so that you can clearly hear this incoming acoustic signal. At the same time you can have a conversation through the microphone 18 into the acoustic data transmission, coding and decoding device 16 lead to the purpose of decoding, so that the acoustic data transmission, coding and decoding device 16 decoded response signal to the wireless telecommunications module 11 is transmitted, whereby this processed acoustic response signal 22 transmitted to a radio-controlled Bluetooth cell phone (as in 1 ) Shown. In this way, a wireless Bluetooth headset 10 according to an embodiment of the present invention, an incoming call signal by the digital signal processor 12 process advantageously and to the digital signal processor 12 connected drive circuit 14 control, creating a drive signal to control the vibrator 15 can be generated to indicate an incoming call signal. At the same time, full-duplex data transmission can also be carried out by the wireless telecommunications module 11 be achieved. The above-mentioned wireless communication module 11 is a Bluetooth telecommunication module 11 ,

It will now refer to the 2 taken. The digital signal processor 12 is through a switch 13 with the drive circuit 14 connected. The desk 13 is a toggle switch and is used to switch the drive circuit on and off 14 who the swinger 15 can switch on or off accordingly to that of the wireless telecommunications module 11 It is advisable to switch the received call signal on or off so that a user of a wireless Bluetooth headphone according to the invention can switch on or off such a vibration function at any time in order to save the energy of the device.

An advantage of the above construction, however, is that the wireless headphones with vibration function according to the invention receive an incoming call signal through a wireless telecommunication module 11 can receive, whereby the incoming call signal further by the digital signal processor 12 to control the drive circuit 14 is processed so that a drive signal to actuate the vibrator 15 is generated to display a warning signal.

There can be various modifications in the different embodiment be made.
