The specific implementation mode is as follows:
example 1
The term "coupled" as used throughout this specification, including the claims, may refer to any means for directly or indirectly connecting. For example, if a first device couples (or connects) to a second device, it should be construed that the first device may be directly connected to the second device or the first device may be indirectly connected to the second device through other devices or some means of connection. Further, wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts. Elements/components/steps in different embodiments using the same reference numerals or using the same terms may be referred to one another in relation to the description.
FIG. 1 is a schematic diagram illustrating an application scenario of a plurality of game platforms according to an embodiment of the present invention. In the application scenario shown in fig. 1, three users (e.g., users 11, 12, and 13 shown in fig. 1) each operate a game platform (e.g., game platforms 21, 22, and 23 shown in fig. 1) to play an online game. Gaming platform 21, gaming platform 22, and/or gaming platform 23 may be a personal computer, notebook computer, tablet computer, cellular telephone, or other gaming platform.
The first connection interface of the game platform 21 is connected to the acoustic-electric conversion device 41. The acoustic-electric conversion device 41 has a speaker and a microphone. According to design requirements, the speaker and the microphone can be embedded in the same product (e.g., a headset, i.e., a headset with a microphone). In other application scenarios, the speaker and the microphone of the sound-electricity conversion device 41 may be two independent products. The sound-electricity conversion device 42 and the sound-electricity conversion device 43 shown in fig. 1 can be analogized by referring to the related description of the sound-electricity conversion device 41, and thus, the description thereof is omitted.
Real-time audio of the game platform 21 may be delivered to the acousto-electric conversion device 41. Therefore, the user 11 can hear the real-time sound effect of the online game from the sound-electricity converting device 41 during the game. The description of the game platform 22 and the game platform 23 shown in fig. 1 can be analogized with reference to the description of the game platform 21, and thus the description thereof is omitted.
It is assumed herein that user 11, user 12 and user 13 all belong to the same team in the online game. The game platform 21, the game platform 22 and the game platform 23 can be connected in series by using regional private lines so as to transmit audio to each other. For example, two ends of the dedicated line 51 are respectively coupled to the second connection interface of the game platform 21 and the third connection interface of the game platform 22, two ends of the dedicated line 52 are respectively coupled to the second connection interface of the game platform 22 and the third connection interface of the game platform 23, and two ends of the dedicated line 53 are respectively coupled to the second connection interface of the game platform 23 and the third connection interface of the game platform 21.
The acoustoelectric conversion device 41 can convert the voice of the user 11 into audio (referred to herein as acoustoelectric conversion audio). The game platform 21 can transmit the sound-electricity conversion audio (the voice of the user 11) of the sound-electricity conversion device 41 to the game platform 23 via the dedicated line 53. The game deck 23 can transmit the sound-electricity conversion audio (the voice of the user 11) from the game deck 21 to the sound-electricity conversion means 43, so that the user 13 can hear the real-time voice of the user 11 from the sound-electricity conversion means 43. The game platform 23 may also pass the sound-to-electricity converted audio (the voice of the user 11) from the game platform 21 to the game platform 22 via the dedicated line 52. The game platform 22 can transmit the sound-electricity conversion audio (the voice of the user 11) from the game platform 23 to the sound-electricity conversion device 42, so that the user 12 can hear the real-time voice of the user 11 from the sound-electricity conversion device 42. By analogy, the real-time voice of the user 12 can be transmitted to the user 11 and the user 13 through the game platforms 21-23, and the real-time voice of the user 13 can also be transmitted to the user 11 and the user 12 through the game platforms 21-23.
Based on the above, the plurality of game platforms 21-23 (or more game platforms) can transmit audio to each other by using a regional private line. The user can connect all players of the own team in series to mutually transmit audio, and can hear the real-time sound effect of the online game of the own game platform. The audio transmitted between these game platforms 21-23 will not be uploaded to the server (not shown) of the online game, so as to achieve the effect of real-time secret communication between multiple users.
Fig. 2 is a schematic circuit block diagram of the game platform 21 in fig. 1 according to an embodiment of the invention. The game platforms 22 and 23 shown in fig. 1 can be analogized with reference to the description of the game platform 21 shown in fig. 2, and thus the description thereof is omitted. In the embodiment shown in fig. 2, the game platform 21 includes a central processing unit 210, an audio interface circuit 220, a first equalizer circuit 230, a first mixing circuit 240, a second mixing circuit 250, a first connection interface 260, a second connection interface 270, and a third connection interface 280. The central processing unit 210 may run an operating system and/or an application (e.g., an online game). The CPU 210 may output audio data of the online game to the audio interface circuit 220. The audio interface circuit 220 receives and processes the audio data from the CPU 210 to generate the host audio to the second mixing circuit 250. The audio interface circuit 220 may be a well-known audio processing circuit or other audio interface circuit/element, depending on design requirements.
The first connection interface 260 may provide a communication interface to establish a connection with the acousto-electric conversion device 41. The second connection interface 270 may provide a communication interface to establish a connection with another gaming platform (e.g., gaming platform 22). The first connection interface 260 and/or the second connection interface 270 may be a Universal Serial Bus (USB) connection interface, an RCA terminal (rcajack or RCA connector) connection interface, an audio connector connection interface, or other connection interfaces according to design requirements. The second mixing circuit 250 is coupled to the audio interface circuit 220 to receive host audio. Second mixing circuit 250 is coupled to second connection interface 270 to receive the first platform voice signals from gaming platform 22. The second mixing circuit 250 mixes the host audio from the audio interface circuit 220 with the first platform voice signal from the second connection interface 270 to generate an output audio. The second mixing circuit 250 outputs the output audio to the acoustic-electric conversion apparatus 41 via the first connection interface 260.
An input of the first equalizer circuit 230 is coupled to the first connection interface 260 to receive the acoustoelectric conversion audio generated by the acoustoelectric conversion device 41. The first equalizer circuit 230 performs an equalization operation on the sound-electricity converted audio to generate a first equalized audio for the first mixing circuit 240. The first equalizer circuit 230 may be a conventional audio equalizer or other equalizer circuit/device, depending on design requirements. The first mixing circuit 240 is coupled to the first equalizer circuit 230 to receive the first equalized audio. The first audio mixing circuit 240 is coupled to the second connection interface 270 to receive the first platform audio signal output by the first game platform. The first mixing circuit 240 mixes the first equalized audio with the first platform speech signal to generate a second platform speech signal. The first mixing circuit 240 outputs the second platform voice signal to the third connection interface 280. The third connection interface 280 may provide a communication interface to establish a connection with another gaming platform, such as gaming platform 23. The third connection interface 280 may be a USB connection interface, RCA terminal connection interface, audio connector connection interface or other connection interfaces according to design requirements. Accordingly, the first mixing circuit 240 may output the second platform voice signal to another game platform (e.g., game platform 23) via the third connection interface 280 and the dedicated line 53.
FIG. 3 is a flowchart illustrating an audio processing method of a game platform according to an embodiment of the invention. Please refer to fig. 2 and fig. 3. In step S310, the audio interface circuit 220 processes the audio data of the cpu 210 to generate a host audio for the second audio mixing circuit 250, the first connection interface 260 provides a communication interface to connect to the audio-to-electrical conversion device 41, the second connection interface 270 provides a communication interface to connect to another game platform (e.g., the game platform 22), and the third connection interface 280 provides a communication interface to connect to another game platform (e.g., the game platform 23).
In step S320, the first equalizer circuit 230 performs an equalization operation on the sound-electricity conversion audio of the sound-electricity conversion device 41 to generate a first equalized audio. In step S330, the first mixing circuit 240 mixes the first equalized audio from the first equalizer circuit 230 with the first platform audio signal from the second interface 270 to generate a second platform audio signal for the third interface 280. The second platform voice signal may be output to the game platform 23 via the third connection interface 280 and the dedicated line 53. Therefore, during the game, the user 13 can hear the real-time voice of the user 11 from the sound-electricity converting device 43, and the user 13 can also hear the real-time voice of the user 12 from the sound-electricity converting device 43.
In step S340, the second mixing circuit 250 mixes the host audio from the audio interface circuit 220 with the first platform audio signal from the second connection interface 270 to generate an output audio to the first connection interface 260. This output audio can be output to the acousto-electric conversion device 41 via the first connection interface 260. Therefore, during the game, in addition to the real-time sound effect of the online game being heard by the user 11 from the sound-electricity converting device 41, the user 11 can hear the real-time voice of the user 12 (even the user 13) from the sound-electricity converting device 41.
Referring to fig. 2, the embodiment is not limited to the implementation of the first mixing circuit 240. For example, the first mixing circuit 240 shown in fig. 2 may include an equalizer circuit 241 and a mixer circuit 242. The input of the equalizer circuit 241 is coupled to the second connection interface 270 to receive the first platform voice signal from the game platform 22. The equalizer circuit 241 performs an equalization operation on the first platform voice signal to generate a second equalized audio to the mixer circuit 242. The equalizer circuit 241 may be a conventional audio equalizer or other equalizer circuit/device, depending on design requirements. The mixer circuit 242 is coupled to the first equalizer circuit 230 to receive the first equalized audio. The mixer circuit 242 is coupled to the equalizer circuit 241 to receive the second equalized audio. The mixer circuit 242 mixes the first equalized audio and the second equalized audio to generate a second platform audio signal for the third connection interface 280. The second platform voice signal can be transmitted to the game platform 23 via the third connection interface 280 and the dedicated line 53. The mixer circuit 242 may be a known mixer or other mixing circuit/element according to design requirements.
The present embodiment does not limit the implementation of the second mixing circuit 250. For example, the second mixing circuit 250 shown in fig. 2 includes a mixer circuit 251 and an equalizer circuit 252. Mixer circuit 251 is coupled to audio interface circuit 220 to receive host audio. Mixer circuit 251 is coupled to second connection interface 270 to receive the first platform voice signal of gaming platform 22. The mixer circuit 251 mixes the host audio and the first platform voice signal to generate a mixed signal to the equalizer circuit 252. The mixer circuit 251 may be a known mixer or other mixing circuits/elements according to design requirements. An input of the equalizer circuit 252 is coupled to the mixer circuit 251 to receive the mixed signal. The equalizer circuit 252 may perform an equalization operation on the mixed audio signal to generate output audio to the first connection interface 260. This output audio is transmitted to the acousto-electric conversion device 41 via the first connection interface 260. The equalizer circuit 252 may be a conventional audio equalizer or other equalizer circuit/device, depending on design requirements.
Example 2
FIG. 4 is a block diagram of a circuit of the game platform 21 of FIG. 1 according to another embodiment of the present invention. The game platforms 22 and 23 shown in fig. 1 can be analogized with reference to the description of the game platform 21 shown in fig. 4, and thus the description thereof is omitted. In the embodiment shown in fig. 4, the game platform 21 includes a central processing unit 210, an audio interface circuit 220, a first equalizer circuit 230, a first mixing circuit 240, a second mixing circuit 250, a first connection interface 260, a second connection interface 270, a third connection interface 280, a first detection circuit 410, a second detection circuit 420, a third detection circuit 430, and a control circuit 440. The cpu 210, the audio interface circuit 220, the first equalizer circuit 230, the first mixing circuit 240, the second mixing circuit 250, the first connection interface 260, the second connection interface 270, and the third connection interface 280 shown in fig. 4 may be analogized with reference to the related description of fig. 2, and therefore, the description thereof is omitted.
In the embodiment shown in fig. 4, the first detecting circuit 410 can detect whether the second connection interface 270 is connected to another game platform (e.g., the game platform 22) to generate a first detecting result to the control circuit 440. The second detection circuit 420 can detect whether the third connection interface 280 is connected to another game platform (e.g., the game platform 23) to generate a second detection result to the control circuit 440. The third detecting circuit 430 may detect whether the first connecting interface 260 is connected to the acoustic-electric converting device 41, so as to generate a third detecting result to the control circuit 440.
The control circuit 440 is coupled to the first detection circuit 410 for receiving the first detection result. The control circuit 440 is coupled to the second detection circuit 420 for receiving the second detection result. The control circuit 440 is coupled to the third detection circuit 430 to receive the third detection result. When the second connection interface 270 is connected to the game platform 22 and the third connection interface 280 is connected to the game platform 23, the control circuit 440 controls the first equalizer circuit 23 to provide the first equalized audio to the first audio mixing circuit 240, but not to the audio interface circuit 220. When the second connection interface 270 is not connected to the game platform 22 or the third connection interface 280 is not connected to the game platform 23, the control circuit 440 controls the first equalizer circuit 230 to provide the first equalized audio to the audio interface circuit 220. When the first connection interface 260 is connected to the acoustic-electric conversion apparatus 41, the control circuit 440 controls the audio interface circuit 220 to supply the host audio to the second mixing circuit 250. When the first connection interface 260 is not connected to the sound-electricity converting device 41, the control circuit 440 controls the audio interface circuit 220 to provide the host audio to a predetermined speaker (not shown) of the game platform 21 (for example, a built-in speaker of a notebook computer).
FIG. 5 is a flowchart illustrating an audio processing method of a game platform according to another embodiment of the invention. Please refer to fig. 4 and 5. In step S510, the audio interface circuit 220 uses a preset speaker (not shown) of the game platform 21 (for example, a built-in speaker of a notebook computer) to play real-time sound effects of the online game. In step S520, the control circuit 440 detects whether the first connection interface 260 is connected to the sound-electricity converting device 41 (e.g., an earphone and/or a microphone) through the third detecting circuit 430. When the first connection interface 260 is connected to the sound-to-electricity converting device 41, the control circuit 440 controls the audio interface circuit 220 to provide the host audio to the second mixing circuit 250, so that the user 11 can listen to the real-time sound effects of the online game using the sound-to-electricity converting device 41 (e.g., headphones) (step S530).
In step S540, the control circuit 440 detects whether the second connection interface 270 is connected to another game platform (e.g., the game platform 22) via the first detection circuit 410, and detects whether the third connection interface 280 is connected to another game platform (e.g., the game platform 23) via the second detection circuit 420. When the second connection interface 270 is not connected to the game platform 22 or the third connection interface 280 is not connected to the game platform 23, the control circuit 440 controls the first equalizer circuit 230 to provide the first equalized audio to the audio interface circuit 220 instead of the first audio mixing circuit 240 (step S550). When the second connection interface 270 is connected to the game platform 22 and the third connection interface 280 is connected to the game platform 23, the control circuit 440 controls the first equalizer circuit 23 to provide the first equalized audio to the first audio mixing circuit 240 instead of the audio interface circuit 220 (step S560). Therefore, during the process of playing the online game, the audio that the user 11 wants to transmit to the user 12 and the audio that the user 13 wants to transmit to the server of the online game are not transmitted, so the effect of real-time secret communication between the multiple game platforms (multiple users) is achieved. In addition, the audio transmitted by the game platform 21 and the other game platforms 22-23 will not be transmitted to the server of the online game.
In step S570, the control circuit 440 detects whether the dedicated line 51 is removed from the second connection interface 270 via the first detection circuit 410, and detects whether the dedicated line 53 is removed from the third connection interface 280 via the second detection circuit 420. When the second connection interface 270 is not connected to the game platform 22 or the third connection interface 280 is not connected to the game platform 23, the control circuit 440 proceeds to step S580. In step S580, the control circuit 440 detects whether the sound-electricity converting device 41 (e.g., the earphone) is removed from the first connection interface 260 through the third detecting circuit 430. When the first connection interface 260 is not connected to the sound-electricity converting device 41, the control circuit 440 controls the audio interface circuit 220 to provide the host audio to a predetermined speaker (not shown) of the game platform 21 (for example, a speaker built in a notebook computer), that is, the audio interface circuit 220 uses the predetermined speaker (not shown) of the game platform 21 to play the real-time sound effect of the online game (step S510).
In summary, the game platform according to the embodiments of the present invention can utilize regional dedicated lines to communicate audio with another game platform. The user can concatenate all players of his team to communicate audio to each other and hear real-time sound effects of his gaming platform (e.g., computer). The audio transmitted between the game platform and another game platform will not be transmitted to the server of the on-line game, so the effect of real-time secret communication between multiple game platforms (multiple users) is achieved.
