The stereo headset according to the invention has two separately formed headphone units. Each of the headphone units has at least a wireless communication transceiver module, a power source, a speaker, and a control unit.

The transceiver module is for wireless communication. In other words, the transceiver module receives data transmitted by radio and, if necessary, converts it accordingly into electrical signals. In addition, the transmitting / receiving module may transmit signals via radio.

The power source is used to supply the electronic components of the headphone unit with electrical energy. An example of such an energy source would be a battery or a rechargeable accumulator. In a particularly advantageous embodiment, however, the energy source is designed as a high-capacitance capacitor.

The loudspeaker is used to generate acoustic signals and the control unit is used to control the remaining electronic components of the headphone unit. Preferably, the control unit is designed as a microprocessor having a memory in which information can be stored.

By separate mutually formed headphone units is meant here that the two headphone units - one of which is provided for each of the right ear and the other for the left ear of the user - are not physically connected to each other. In particular, no bracket and no cable connection between the two headphone units are available.

The headset according to the invention is thus completely wireless. Disturbing cables are thus completely eliminated. The stereo earphone set takes up little space and is easy to carry. In this way, the headset set can be used variably and kleinbauend.

Advantageously, the transceiver module operates according to the Bluetooth standard, in particular according to the standard low energy mode according to Bluetooth specification 4.0.

In an advantageous embodiment, the two headphone units of a stereo earphone set are of identical construction. Under construction, the use of identical hardware components is understood here. Software components, on the other hand, can differ from each other. By using identical hardware components, production costs can be reduced.

Furthermore, information can be stored in the control unit that determines the function of the headphone unit, in particular its function as a right or left stereo channel and / or its function as transmitter or receiver in wireless communication. In this way, despite the use of identical hardware components, the functionality of the individual headphone unit can be set / determined.

In further advantageous embodiments, the headphone units can have additional components, namely an amplifier circuit and / or a microphone for recording noises. Also, the headphone units may be waterproof. In this way, the functionality and / or the field of use of the stereo headset can be increased.

In a further advantageous embodiment, the headphone units each have a magnetically actuatable on / off switch. In this way, the headphone units can be turned on or off in a non-contact manner. Most preferably, the on / off switch is mounted internally in the headphone unit.

The charging station according to the invention has two charging stations for charging the respective energy source of the headphone units. In this way a simultaneous - and thus time-efficient - charging of energy sources is possible. In a particularly advantageous manner, the charging takes place via induction, in particular via a wireless inductive method.

In an advantageous embodiment, the loading stations on a magnetic element for locking the headphone units. This ensures safe storage of the headphone units in the charging station. The charging station can do this way too serve as a compact transport container for the headset.

The system according to the invention consists of a wireless stereo headset set, in which the headphone units each have a magnetically actuated on / off switch, and a charging station whose charging stations have a magnetic element for locking the headphone units. The magnetically actuated on / off switch is in its off position when the respective headphone unit is in the loading place.

The headphone units are thus automatically switched off when they are in the charging station and automatically switched on when they are removed from the charging station.

The invention is further explained by means of embodiments in the drawing figures. It show, each schematically:

1 a schematic diagram of a first stereo headset set;

2 a schematic diagram of another stereo headset.

1 and 2 each show a schematic diagram of a stereo headset. The stereo earphone sets of the two figures do not differ in their structural components (hardware components) from each other. The following description of these components therefore refers to both drawing figures.

The headset consists of two headphone units 1 and 2 , The headphone units 1 . 2 are formed separately from each other. Each of the headphone units 1 . 2 is designed here as a so-called in-ear unit. In each of the headphone units 1 . 2 is a transceiver module 3 for wireless communication with an antenna 4 , an energy source 5 , an amplifier circuit 6 , a speaker 7 and a control unit 8th available. Not shown in the figures is a magnetically actuated on / off switch of the headphone units 1 . 2 ,

The control unit 8th controls and controls the remaining components of the respective headphone unit 1 . 2 , The amplifier circuit 6 leads the speaker 7 the electro-acoustic signals too.

An electronic device 9 (eg computer, laptop, notebook, USB stick, mobile phone, smart phone, smartbook) transmits by radio signals that the transmitting / receiving module of at least one of the headphone units 1 . 2 receives and processes.

The two headphone units 1 . 2 are made up of the identical hardware components. The assignment of the functionality of the two headphone units 1 . 2 is done by information (program code) stored in a memory of the control unit 8th is deposited. Depending on the information stored, one of the headphone units serves as the right or left stereo channel. In addition, for example, the function of the individual components in the radio network (eg master, active slave, passive slave) can be set in this way.

The stereo headset is designed as a Bluetooth headset and uses the standard low energy mode according to Bluetooth specification 4.0. The in 1 Stereo headset set forms a so-called piconet with the electronic device 9 out.

The electronic device is the master. A channel (in 1 the headphone unit 2 ) works as a right stereo channel and as an active slave. The headphone unit 2 exchanges with the electronic device 9 the Bluetooth profiles and leads the communication (eg charge level of the power source 5 ) with the master. The other channel (in 1 the headphone unit 1 ) only listens as a passive slave, receives the audio data packets and is designed as a left stereo channel.

The in 2 Stereo headset set forms a so-called. Scatternet with the electronic device 9 out. This scatternet, in turn, is made up of two piconets. In a piconet is the electronic device 9 the master and a channel (in 2 the headphone unit 2 ) the slave. In a second piconet, this channel (in 2 the headphone unit 2 ) the master and the other channel (in 2 the headphone unit 1 ) the slave. The channel in the piconet of the electronic device 9 exchanges with the headphone unit 2 the Bluetooth profiles and realizes the entire communication with this. Also, the audio package for the second channel (in 2 the headphone unit 1 ) and communicate with this channel. The information of the second channel (in 2 the headphone unit 1 ) are in the first channel (in 2 the headphone unit 2 ) and possibly to the electronic device 9 forwarded. Furthermore, the first headphone unit 1 as the left stereo channel and the second headphone unit 2 designed as a right stereo channel.

The two headphone units 1 . 2 can be charged by a charger (not shown in the figures), ie the charger is used to recharge the power source 5 the first and the second headphone unit 1 . 2 with electrical energy.

The charging station has two charging stations for charging the energy sources 5 , In addition, the charging stations each have a magnetic element for locking the headphone units.

Also not shown in the figures is a system consisting of a wireless stereo headset and a charging station, wherein the magnetically actuated on / off switch of the headphone unit 1 . 2 is in the off position when the respective headphone unit 1 . 2 located in the respective loading place.
