The transmitter comprises a transmitter rechargeable battery unit. The system further comprises a mobile wireless receiver for the wireless reception of audio signals transmitted wirelessly by the at least one transmitter, wherein the receiver comprises a receiver rechargeable battery unit. The system further comprises a mobile charging/transport dock which comprises at least one transmitter receiving compartment for receiving a transmitter and a receiver receiving compartment for receiving a receiver and a rechargeable battery unit as power supply. The mobile charging/transport dock is configured to charge the transmitter rechargeable battery unit and/or the receiver rechargeable battery unit with energy from the rechargeable battery unit when they are placed in the corresponding receiving compartments. ## Claims ### Claim 1 A mobile wireless audio transmission system, comprising: at least one mobile wireless transmitter for the wireless transmission of audio signals which have been recorded via a microphone in the wireless transmitter or which have been transmitted via an audio input to the wireless transmitter, wherein the wireless transmitter comprises a transmitter rechargeable battery unit, a mobile wireless receiver for the wireless reception of audio signals transmitted wirelessly by the at least one wireless transmitter, wherein the wireless receiver comprises a receiver rechargeable battery unit and a mobile charging/transport dock which comprises at least one transmitter receiving compartment for receiving a wireless transmitter, a receiver receiving compartment for receiving a wireless receiver and a rechargeable battery unit as power supply, wherein the mobile charging/transport dock is configured to charge the transmitter rechargeable battery unit and/or the receiver rechargeable battery unit with energy from the rechargeable battery unit when they are placed in the corresponding receiving compartments. ### Claim 2 (depends on 1) The mobile wireless audio transmission system according to claim 1, wherein the at least one transmitter is ready to transmit when it is placed in the transmitter receiving compartment, wherein the microphone of the mobile wireless transmitter can freely record audio signals from outside in the inserted state of the transmitter. ### Claim 3 (depends on 1) The mobile wireless audio transmission system according to claim 1, wherein the receiver is ready to receive when it is placed in the receiver receiving compartment, wherein the wireless receiver has a display which can be seen from outside in the inserted state of the receiver. ### Claim 4 (depends on 1) The mobile wireless audio transmission system according to claim 1, wherein the receiver can receive two audio channels from two transmitters. ### Claim 5 (depends on 1) The mobile wireless audio transmission system according to claim 1, wherein the charging/transport dock has two transmitter receiving compartments. ### Claim 6 (depends on 1) The mobile wireless audio transmission system according to claim 1, wherein the charging/transport dock has adapter receiving compartments for receiving various adapters. ### Claim 7 (depends on 1) The mobile wireless audio transmission system according to claim 1, wherein the transmitter has a transmitter memory for storing recorded audio signals. ### Claim 8 (depends on 1) The mobile wireless audio transmission system according to claim 1, wherein the wireless transmitter has a microphone and/or an audio input and a clip by means of which the wireless transmitter can be fastened to an item of clothing of a user. ### Claim 9 (depends on 1) The mobile wireless audio transmission system according to claim 1, wherein the at least one wireless transmitter can transmit an audio signal wirelessly to the receiver and/or an external smart device. ### Claim 10 (depends on 1) The mobile wireless audio transmission system according to claim 1, wherein the wireless receiver has a data connection by means of which the wireless receiver can be coupled to an external video camera or an external smart device or another electronic device for transmission of audio signals. ### Claim 11 (depends on 1) The mobile wireless audio transmission system according to claim 1, wherein the charging/transport dock has a data connection by means of which an audio signal can be output from the wireless transmitter in the transmitter receiving compartment or an audio signal stored in a memory of the charging/transport dock can be output. ### Claim 12 A mobile charging/transport dock comprising: at least one transmitter receiving compartment for receiving a wireless transmitter, a receiver receiving compartment for receiving a wireless receiver and a rechargeable battery unit as power supply, wherein the charging/transport dock is configured to charge the transmitter rechargeable battery unit and/or the receiver rechargeable battery unit with energy from the rechargeable battery unit when they are placed in the corresponding receiving compartments. ### Claim 13 A hand microphone comprising: a microphone handle in the form of a charging/transport dock having a transmitter receiving compartment for receiving a wireless transmitter and a rechargeable battery unit as power supply and a wireless transmitter for the wireless transmission of audio signals which have been recorded via a microphone in the transmitter or which have been transmitted via an audio input to the transmitter, wherein the wireless transmitter has a transmitter rechargeable battery unit as power supply and can be placed in the transmitter receiving compartment, wherein the wireless transmitter can transmit the audio signals wirelessly when it is located in the transmitter receiving compartment and when it is not located in the transmitter receiving compartment. ### Claim 14 (depends on 1) A mobile wireless audio transmission system according to claim 1, wherein the mobile charging/transport dock comprises a first front side and a second front side, wherein a length of the mobile charging/transport dock
