[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person skilled in the art without creative work fall within the protection scope of the present application.

[0029] It should be noted that the following embodiments can be combined without conflict.

[0030] Referring to Figure 1 The voice transmission device 400 provided by the embodiments of the present application can include a transmitter 10, and the transmitter 10 includes a first bidirectional transceiver 11 and a unidirectional transmitter 12. The voice transmission device 400 in the embodiments of the present application further includes a plurality of second bidirectional transceivers 20 and a plurality of unidirectional receivers 30.

[0031] The first bidirectional transceiver 11 and the unidirectional transmitter 12 are both electrically connected with the host 100, and the first bidirectional transceiver 11 is electrically connected with the unidirectional transmitter 12. The plurality of second bidirectional transceivers 20 are correspondingly electrically connected with the plurality of live clients 200, each second bidirectional transceiver is electrically connected with the first bidirectional transceiver 11, and there is no signal transmission between the plurality of second bidirectional transceivers 20. The plurality of unidirectional receivers 30 are correspondingly electrically connected with the plurality of viewer clients 300, and each unidirectional receiver 30 is electrically connected with the unidirectional transmitter 12.

[0032] At the same time, one of the plurality of live clients 200 is set as a bidirectional transceiving end, and the second bidirectional transceiver 20 corresponding to the bidirectional transceiving end has a bidirectional function, i.e., has a receiving / transmitting bidirectional function. The second bidirectional transceiver 20 corresponding to the other live clients 200 in the plurality of live clients 200 is used as a receiver, and the second bidirectional transceiver 20 corresponding to the other live clients 200 in the plurality of live clients 200 cannot be used as the transmitter 10.

[0033] The second bidirectional transceiver 20 corresponding to the bidirectional transceiving end can transmit the audio signal generated locally by the bidirectional transceiving end to the first bidirectional transceiver 11, and can transmit the audio signal from the host 100 sent by the first bidirectional transceiver 11 to the bidirectional transceiving end. The second bidirectional transceiver 20 corresponding to the live client 200 other than the bidirectional transceiving end among the plurality of live clients 200 can transmit the audio signal from the host 100 sent by the first bidirectional transceiver 11 to the corresponding live client 200.

[0034] The first bidirectional transceiver 11 is used for receiving the audio signal from the host 100 and the audio signal sent by the bidirectional transceiving end through the corresponding second bidirectional transceiver 20 and mixing to obtain a mixed audio signal, and transmitting the mixed audio signal to each unidirectional receiver 30 through the unidirectional transmitter 12, so as to transmit the mixed audio signal to the corresponding audience client 300 through each unidirectional receiver 30.

[0035] The voice transmission device 400 of the embodiment of the application realizes the wireless communication connection between the host 100 and the plurality of live clients 200 and the plurality of audience clients 300 through the cooperation of the transmitter 10, the plurality of second bidirectional transceivers 20 and the plurality of unidirectional transmitters 12, and can convert the existing single-person live broadcast into team live broadcast, and the host 100 can control the plurality of live clients 200 and can switch one of the plurality of live clients 200 to become a bidirectional transceiving end at any time to perform the continuous microphone.

[0036] In the embodiment of the application, the transmitter 10 has a bidirectional function, can transmit the audio signal from the host 100 to the audience client 300 through the unidirectional transmitter 12, can receive the audio signal sent by the bidirectional transceiving end, and can mix the audio signal from the host 100 and the audio signal from the bidirectional transceiving end, and can transmit the mixed audio signal to the audience client 300.

[0037] Specifically, the functions of the transmitter 10 are as follows:

[0038] (1) The first bidirectional transceiver 11 can transmit the audio signal transmitted by the host 100 to each second bidirectional transceiver 20;

[0039] (2) The first bidirectional transceiver 11 can receive the audio signal of the bidirectional transceiving end sent by the second bidirectional transceiver corresponding to the bidirectional transceiving end, and transmit to the unidirectional transmitter 12;

[0040] (3) The unidirectional transmitter 12 is responsible for mixing the audio signal from the host 100 and the audio signal from the bidirectional transceiving end, and transmitting the mixed audio signal to each unidirectional receiver 30 to transmit to each audience client 300.

[0041] The transmitter 10 adopts one first bidirectional transceiver 11 and one one-way transmitter 12 to determine the transmission direction of the audio signal, so that the audience client 300 can listen to all the audio signals in the system, and the second bidirectional receiver of the live client 200 can only hear the audio signal from the host 100, but cannot hear the audio signal transmitted by itself.

[0042] Optionally, the host 100 can be connected with the first bidirectional transceiver 11 and the one-way transmitter 12 through the 3.5 audio input interface and / or the USB audio input interface to realize the transmission of the audio signal.

[0043] The host 100 can connect multiple live clients 200 through the voice transmission device 400. For example, if the voice transmission device 400 includes eight second bidirectional transceivers 20, the host 100 can connect eight live clients 200 through the voice transmission device 400, and any one of the eight live clients 200 can be set as a bidirectional transceiving end by the host 100.

[0044] The live client 200 set as the bidirectional transceiving end can receive the audio signal from the host 100 through the first bidirectional transceiver 11 and the corresponding second bidirectional transceiver 20 (i.e. the second bidirectional transceiver 20 electrically connected with the bidirectional transceiving end), and can upload the audio signal (which can be the sound signal of the user obtained locally and / or the audio signal stored locally) obtained locally by the bidirectional transceiving end to the first bidirectional transceiver 11 through the corresponding second bidirectional transceiver 20. After receiving the audio signal from the bidirectional transceiving end, the first bidirectional transceiver 11 can transmit the audio signal from the bidirectional transceiving end to the audience client 300. Since there is no signal transmission between multiple second bidirectional transceivers 20, the first bidirectional transceiver 11 cannot transmit the audio signal from the bidirectional transceiving end to the live clients 200 other than the bidirectional transceiving end, i.e. all the live clients 200 cannot hear the audio signal transmitted by the second bidirectional transceiver 20.

[0045] The first bidirectional transceiver 11 transmits the audio signal from the host 100 to each second bidirectional transceiver 20 and each one-way receiver 30.

[0046] It should be noted that the second bidirectional transceiver 20 is responsible for receiving the audio signal from the host 100 transmitted by the first bidirectional transceiver 11, and can transmit the local audio signal of the live client 200 electrically connected with the second bidirectional transceiver 20 to the first bidirectional transceiver 11, but cannot receive the local audio signal.

[0047] The audience client 300 can receive the mixed audio signal, and the number of the audience client 300 can reach 100 or even more.

[0048] The host 100 can be the main broadcaster, the live streaming client 200 can be the secondary broadcaster, and the viewer client 300 can be the monitoring headset. In this way, the main broadcaster can control multiple secondary broadcasters and can switch between one of the multiple secondary broadcasters at any time to connect with each other. At the same time, multiple monitoring headsets can be connected.

[0049] The host 100 can be a sound card or a computer, or other types of devices capable of capturing / sending / receiving sound.

[0050] See Figure 2 The live streaming client 200 can be a mobile phone; it should be understood that the live streaming client 200 can also be other types of devices capable of capturing / sending / receiving sound, such as a PAD.

[0051] See Figure 2 The audience client 300 can be headphones; it should be understood that the audience client 300 can also be other types of devices capable of receiving sound.

[0052] In this embodiment of the invention, the first bidirectional transceiver 11 and the unidirectional transmitter 12 are integrated, that is, the transmitter 10 integrates the first bidirectional transceiver 11 and the unidirectional transmitter 12, and the transmitter 10 has a simple structure. In other embodiments, the transmitter 10 can use multiple modules stacked together to realize the functions of the first bidirectional transceiver 11 and the unidirectional transmitter 12.

[0053] The transmitter 10 can be located within the host 100, meaning the transmitter 10 is part of the host 100, reducing system structural complexity. In other embodiments, the transmitter 10 can also be independent of the host 100.

[0054] The second bidirectional transceiver 20 is configured within the corresponding live streaming client 200, meaning it is part of the live streaming client 200, thus reducing system complexity. In other embodiments, the second bidirectional transceiver 20 may be independent of the live streaming client 200.

[0055] The unidirectional receiver 30 is located within the viewer client 300, meaning it is part of the viewer client 300, reducing system complexity. Furthermore, the use of the unidirectional receiver 30 in the viewer client 300 reduces its power consumption and extends its usage time. In other embodiments, the unidirectional receiver 30 may be independent of the viewer client 300.

[0056] See also Figure 1 The present invention also provides a live streaming system, including a host 100, multiple live streaming clients 200, multiple viewer clients 300, and the voice transmission device 400 in the above embodiments.

[0057] The host 100 can be a sound card or a computer.

[0058] Referring to Figure 2 The live broadcast client 200 can be a mobile phone, and the audience client 300 can be a headset.

[0059] The above embodiments are only used to illustrate the technical solutions of the present application, but not limit the present application; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
