Hi-fi headphones with a mobile phone

The invention relates to a device with a mobile phone for making telephone calls, with an earphone and with a control device connected to the mobile phone and the earphone, to which an audio signal source can be connected, the control device being designed in such a way that it Passes audio signals from the audio signal source to the earphones and that - when a phone call is received in the mobile phone - it switches through the phone call to the earphones.

Such a device is commercially available from Ericsson. Specifically, Ericsson sells the SH888 mobile terminal, to which a radio with the product name HPR08 and a portable hands-free system can be connected. The radio HPR08 has a control device that mutes the radio during incoming phone calls and switches the incoming phone call on to the portable hands-free device.

The invention has for its object to develop a device of the type mentioned in such a way that it is particularly user-friendly.

This object is achieved according to the invention in that the device is formed by a hi-fi headphone with two ear-covering or ear-cups connected by a strap, the mobile phone being integrated in one of the two ear cups, the control device being integrated in one of the two ear cups and the earphone is formed by a loudspeaker unit of the hi-fi headphone. The cell phone and the Control devices can be integrated in the same ear cup or in different ear cups.

A significant advantage of the device according to the invention is that it is designed as a hi-fi headphone with two ear cups connected by a bracket; because due to this design of the device, a particularly good sound quality is achieved when listening to the audio signals or when listening to the incoming telephone calls. Another essential advantage of the device according to the invention is that the mobile telephone and the control device are integrated in one of the two ear cups or in the ear cups; because this integration of the control device and the mobile phone in the hi-fi headphones achieves a particularly compact structure of the device according to the invention. This compact structure of the device according to the invention also results in a particularly high level of user-friendliness, because a user only has to put on the hi-fi headphones to receive both audio signals

Hear audio signal source as well as being able to make phone calls. A cumbersome wiring of the mobile phone, control device and earphones - as is required in the prior art described at the outset - is eliminated in the device according to the invention due to the

Integration of the mobile phone and the control device in the hi-fi headphones.

In order to enable a compact construction of the device according to the invention or of the hi-fi headphones according to the invention, it is considered to be advantageous if the transmitting / receiving antenna of the mobile telephone is integrated in the bracket.

In order to avoid that the transmitting / receiving antenna of the mobile phone integrated in the bracket is electromagnetic Radiates radiation in the direction of the user's head, it is according to a development of the invention

Device is considered advantageous if the sender

/ Receiving antenna of the mobile phone is integrated in the bracket in such a way that it has a transmission characteristic facing away from the inside of the bracket.

A particularly compact structure of the device according to the invention is advantageously achieved in that the audio signal source is a hi-fi signal source which is integrated in one of the two ear cups; This prevents the user from having to connect a separate audio signal source to the hi-fi headphones.

If the hi-fi signal source is a radio integrated in one of the two ear cups, the radio antenna should be integrated in the bracket in order to enable particularly good radio reception.

In order to clearly signal the user of the device according to the invention that a telephone call has been received, it is considered advantageous if the control device is designed in such a way that, as soon as a telephone call is received in the mobile phone, it generates an advisory tone for the user in the loudspeaker unit.

In addition, to enable the user to decide whether or not to accept an incoming telephone call, it is considered advantageous if the control device has an operating device with which an operating signal can be generated by the user, and the control device is designed in this way that it only switches through an incoming telephone call to the loudspeaker unit when the actuation signal has been generated. If, on the other hand, the device according to the invention is to be designed in such a way that incoming calls are always forwarded to the hi-fi headphones, it is considered advantageous if the control device is designed in such a way that - as soon as a telephone call arrives in the mobile phone - the audio signals are forwarded to the loudspeaker unit and instead only switches through the telephone call to it.

Otherwise, it is also conceivable that the user wishes that the audio signals to the hi-fi headphones are also switched through in addition to the telephone calls; In this case, it is considered advantageous if the control device is designed such that it reduces the volume of the audio signals for the loudspeaker unit after the telephone call has been switched through to the loudspeaker unit.

To illustrate the invention shows

1 shows an exemplary embodiment of the device according to the invention or the hi-fi headphones according to the invention and FIG. 2 shows the hi-fi headphones according to the invention according to FIG. 1 “in use”.

FIG. 1 shows - very schematically - a hi-fi headphone 10 with two ear cups 20 and 25 connected to one another by a clip 15. In the left ear cup 20 of the hi-fi headphone 10 in FIG. 1 there is a control device 25, a mobile telephone 30, a externally accessible and operable control device 35, a radio device 40 and a loudspeaker 42 are integrated. The control device 25 has a first connection E1 to the operating device 35, a second connection E2 to the mobile telephone 30, a third connection E3 to the radio device 40 and with a fourth connection E4 connected to the loudspeaker 42. The control device 25 is also connected to a loudspeaker 43 mounted in the other auricle 25, which together with the loudspeaker 42 forms a loudspeaker unit 45; the connection between control device 25 and loudspeaker 43 is not shown in FIG. 1 for the sake of clarity. Otherwise, the mobile phone 30 of the hi-fi headphones 10 has a microphone for voice input for making calls; this microphone is also not shown in FIG. 1 for the sake of clarity. This microphone can, for example, be integrated in one of the two ear cups or instead be designed as an additional part which is plugged into the hi-fi headphones 10.

The radio device 40 and the mobile phone 30 are each equipped with transmission / reception antennas; these can be integrated in the bracket 15, for example. In order to ensure that virtually no or only negligibly little electromagnetic radiation is emitted in the direction of the user's head, the antennas should be one of the

Have inside of bracket 50 facing transmission or reception characteristics. This can be achieved, for example, by covering the inside of the temple 50 with a metallic film which has a shielding effect.

FIG. 2 shows the hi-fi headphones 10 according to FIG. 1 “in use”. One recognizes an audio signal source 110 - for example a CD player or a radio - which, via an interface 115, is in a radio communication standard A - for example DECT or Bluetooth standard - working base station 120. The base station 120 is connected to the radio device 40 of the hi-fi headphone 10 via a radio link in the communication standard A, ie the radio device 40 works in the same radio communication standard A as the base station 120. In addition, another base station 160 can be seen in FIG. 2, which operates in a further communication standard B - for example the GSM radio standard - and is connected to the mobile phone 30 of the hi-fi headphones 10. This further base station 160 is connected to a public telephone network (PSTN) 170 via a further interface 165.

The arrangement according to FIG. 2 is operated as follows (in the description reference is made to both FIGS. 1 and 2):

An audio signal SA is generated by the audio signal source 110. The audio signal SA is transmitted via the one interface 115 to the one base station 120, from which it arrives at the radio device 40 and thus at the control device 25 of the hi-fi headphone 40. "In normal operation", the control device 25 switches through the audio signals SA received with the radio device 40 to the loudspeaker unit 45 so that a user of the hi-fi headphones 10 can hear them.

If a telephone call is now switched from the public telephone network (PSTN) 170 and thus via the further base station 160 to the cell phone 30 of the hi-fi headphones 10, the cell phone 30 generates a corresponding data signal D for the control device 25. When this data signal D is present, it is generated the control device 25 then an auxiliary signal Sh, which is transmitted to the loudspeaker unit 45 and triggers an advisory tone for the user. As soon as the user hears the advisory tone, he can operate the operating device 35 in order to switch the incoming telephone call to the loudspeaker unit 45; specifically, when the operating device 35 is actuated, an actuation signal BT is generated which notifies the control device 25 that the previous telephone call to the loudspeaker unit 45 is to be switched through.

The telephone call can be switched through in various ways: for example, only the telephone call to the loudspeaker unit 45 can be switched through; the control device 25 would then interrupt the connection between the radio device 40 and the loudspeaker unit 45, so that the audio signals SA can then no longer reach the loudspeaker unit 45 during a telephone call. Instead, the control device 25 can also be designed differently, namely in such a way that it reduces the volume of the audio signals SA to the loudspeaker unit 45 during a switched call. This means that audio signals can still be listened to "in the background" while telephoning.

As a third variant, the control device 25 could be designed such that it immediately connects an incoming call to the loudspeaker unit 45, that is to say regardless of whether an actuation signal BT was generated with the operating device 35 or not.

To realize a hi-fi headphone 10 according to FIG. 1, for example, the components known from the previously known device described at the beginning can be used.

Otherwise, instead of or in addition to the radio device 40, a hi-fi signal source can be used, for example

Radio - be integrated in one of the two ear cups 20 or 25. In the case of a radio, the radio antenna should then advantageously be integrated in the bracket 15 of the hi-fi headphones 10.
