Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to fall within the scope of the invention.
It should be noted that the following embodiments may be combined without conflict.
Referring to fig. 1, an embodiment of the present invention provides a voice transmission apparatus 400, and the voice transmission apparatus 400 may include a transmitter 10, and the transmitter 10 includes a first bidirectional transceiver 11 and a unidirectional transmitter 12. The voice transmission apparatus 400 in the embodiment of the present invention further includes a plurality of second bidirectional transceivers 20 and a plurality of unidirectional receivers 30.
Wherein the first bi-directional transceiver 11 and the unidirectional transmitter 12 are both electrically connected to the host 100, and the first bi-directional transceiver 11 is electrically connected to 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 receiver is electrically connected with the first bidirectional transceiver 11, and no signal is transmitted between the plurality of second bidirectional transceivers 20. A plurality of unidirectional receivers 30 are electrically connected to a plurality of viewer clients 300, respectively, each unidirectional receiver 30 being electrically connected to a unidirectional transmitter 12.
At the same time, one of the live clients 200 is set as a bidirectional transceiver, and the second bidirectional transceiver 20 corresponding to the bidirectional transceiver has a bidirectional function, i.e., a reception/transmission bidirectional function. The second bidirectional transceiver 20 corresponding to the other live clients 200 except the bidirectional transceiver among the plurality of live clients 200 is used as a receiver, and the second bidirectional transceiver 20 corresponding to the other live clients 200 except the bidirectional transceiver among the plurality of live clients 200 cannot be used as a transmitter 10.
The second bidirectional transceiver 20 corresponding to the bidirectional transceiver can transmit the audio signal locally generated by the bidirectional transceiver to the first bidirectional transceiver 11, and can transmit the audio signal from the host 100 transmitted by the first bidirectional transceiver 11 to the bidirectional transceiver. The second bidirectional transceiver 20 corresponding to the other live clients 200 except the bidirectional transceiver among the plurality of live clients 200 can transmit the audio signal from the host 100 transmitted by the first bidirectional receiving audience client 300 transmitter to the corresponding live client 200.
The first bi-directional transceiver 11 is configured to receive and mix an audio signal from the host 100 and an audio signal transmitted by the bi-directional transceiver through the corresponding second bi-directional transceiver 20, obtain a mixed audio signal, and transmit 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 viewer client 300 through each unidirectional receiver 30.
According to the voice transmission device 400 of the embodiment of the invention, through the cooperation of the transmitter 10, the plurality of second bidirectional transceivers 20 and the plurality of unidirectional transmitters 12, the wireless communication connection between the host 100 and the plurality of live broadcast clients 200 and the plurality of audience clients 300 is realized, the live broadcast of the existing single person can be converted into team live broadcast, the host 100 controls the plurality of live broadcast clients 200, and 1 of the plurality of live broadcast clients 200 can be switched to be a bidirectional receiving and transmitting end at any time to carry out wheat connection.
In the embodiment of the present invention, the transmitter 10 has a bi-directional function, and can transmit the audio signal from the host 100 to the viewer client 300 through the unidirectional transmitter 12, and simultaneously can receive the audio signal transmitted from the bi-directional transceiver, mix the audio signal from the host 100 with the audio signal from the bi-directional transceiver, and transmit the mixed audio signal obtained by mixing to the viewer client 300.
Specifically, the function of the transmitter 10 is as follows:
(1) The first bidirectional transceiver 11 may transmit the audio signal transmitted from the host 100 to each of the second bidirectional transceivers 20;
(2) The first bidirectional transceiver 11 may receive the audio signal of the bidirectional transceiver end of the second bidirectional transceiver corresponding to the bidirectional transceiver end, and transmit the audio signal to the unidirectional transmitter 12;
(3) The unidirectional transmitter 12 is responsible for mixing the audio signal from the host 100 with the audio signal from the bi-directional transmitting and receiving end and transmitting the mixed audio signal to each unidirectional receiver 30 for transmission to each viewer client 300.
The transmitter 10 adopts 1 first bidirectional transceiver 11 and 1 unidirectional transmitter 12 to determine the transmission flow direction of the audio signals, so that the audience client 300 can monitor all audio signals in the system, and the second bidirectional receiver of the live client 200 can only hear the audio signals from the host 100, but cannot hear the audio signals emitted by the audience client.
Alternatively, the host 100 may be connected to the first bidirectional transceiver 11 and the unidirectional transmitter 12 through a 3.5 audio input interface and/or a USB audio input interface, so as to implement transmission of audio signals.
The host 100 may connect to a plurality of live clients 200 through the voice transmission apparatus 400, if the voice transmission apparatus 400 includes 8 second bidirectional transceivers 20, the host 100 may connect to the 8 live clients 200 through the voice transmission apparatus 400, and any one of the 8 live clients 200 may be set as a bidirectional transceiver by the host 100.
The live client 200, which is set as a bi-directional transceiver, may receive the audio signal from the host 100 through the first bi-directional transceiver 11 and the corresponding second bi-directional transceiver 20 (i.e., the second bi-directional transceiver 20 electrically connected to the bi-directional transceiver), and may upload the locally acquired audio signal (which may be a locally acquired user's voice signal and/or a locally stored audio signal) to the first bi-directional transceiver 11 through the corresponding second bi-directional transceiver 20, and the first bi-directional transceiver 11 may forward the audio signal from the bi-directional transceiver to the viewer client 300 after receiving the audio signal from the bi-directional transceiver. Because there is no signal transmission between the plurality of second bi-directional transceivers 20, the first bi-directional transceiver 11 may not forward the audio signal from the bi-directional transceiver to other live clients 200 of the plurality of live clients 200 except the bi-directional transceiver, i.e., all live clients 200 may not hear the audio signal transmitted by the second bi-directional transceiver 20.
The audio signal from the host 100 transmitted from the first bi-directional transceiver 11 is transmitted to each of the second bi-directional transceivers 20 and also to each of the unidirectional receivers 30.
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 may transmit the local audio signal of the live client 200 electrically connected to the second bidirectional transceiver 20 to the first bidirectional transceiver 11, but may not receive the local audio signal.
The spectator client 300 may receive the mixed audio signal, and the number of spectator clients 300 may be up to 100 or even more.
The host 100 may be a hosting side, the live client 200 may be a secondary hosting side, and the viewer client 300 may be a listening earphone, so that the hosting side may control a plurality of secondary hosting sides below, may switch 1 of the plurality of secondary hosting sides at any time to connect with a wheat, and may connect with a plurality of listening earphones.
The host 100 may be a sound card or a computer, or may be other types of devices capable of capturing/transmitting/receiving sound.
Referring to fig. 2, the live client 200 may be a mobile phone, and it should be understood that the live client 200 may be another type of device capable of capturing/transmitting/receiving sound, such as a PAD.
Referring to fig. 2, the spectator client 300 may be a headset, it being understood that the spectator client 300 may also be other types of devices capable of receiving sound.
In the embodiment of the present invention, the first bidirectional transceiver 11 and the unidirectional transmitter 12 are integrally arranged, that is, the transmitter 10 integrates the first bidirectional transceiver 11 and the unidirectional transmitter 12, and the transmitter 10 has a simple structure. While in other embodiments, the transmitter 10 may use a superposition of multiple modules to implement the functionality of the first bi-directional transceiver 11 and the unidirectional transmitter 12.
The transmitter 10 may be disposed on the host 100, i.e., the transmitter 10 is part of the host 100, reducing system complexity. While in other embodiments, the transmitter 10 may also be independent of the host 100.
The second bidirectional transceiver 20 is disposed on the corresponding live client 200, that is, the second bidirectional transceiver 20 is a part of the corresponding live client 200, so as to reduce the complexity of the system structure. While in other embodiments the second bi-directional transceiver 20 may also be independent of the live client 200.
The unidirectional receiver 30 is disposed at the viewer client 300, i.e. the unidirectional receiver 30 is a part of the viewer client 300, which reduces the complexity of the system structure, and the viewer client 300 adopts the unidirectional receiver 30, reduces the power consumed by the viewer client 300, and prolongs the service life of the viewer client 300. While in other embodiments, the unidirectional receiver 30 may also be independent of the viewer client 300.
Referring again to fig. 1, the embodiment of the present invention further provides a live broadcast system, which includes a host 100, a plurality of live broadcast clients 200, a plurality of viewer clients 300, and the voice transmission apparatus 400 in the above embodiment.
Wherein the host 100 may be a sound card or a computer.
Referring to fig. 2, the live client 200 may be a cell phone and the viewer client 300 may be a headset.
The foregoing embodiments are merely for illustrating the technical solution of the present invention, but not for limiting the same, and although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those skilled in the art that modifications may be made to the technical solution described in the foregoing embodiments or equivalents may be substituted for parts of the technical features thereof, and that such modifications or substitutions do not depart from the spirit and scope of the technical solution of the embodiments of the present invention in essence.
