[0024] FIG. 1 is a flow chart of a channel determination method according to an embodiment of the present invention. As shown in FIG. 1, the method includes the following steps:

[0025] Step 101: Determine the number of speakers based on the acquired output current and output voltage.

[0026] Each step in the embodiment of the present invention may be performed by a computer device, including but not limited to a smart TV, an external device of a smart TV, or a smart TV and an external device.

[0027] In an embodiment of the present invention, Fig. 2 is a schematic diagram of a smart detection module according to an embodiment of the present invention, the smart detection module shown in Fig. 2 is installed in a computer device, and the smart detection module includes a main chip, an audio power amplifier module, a speaker module, a detection circuit, and a comparison circuit, where the main chip is connected to the audio power amplifier module, the audio power amplifier module is connected to the speaker module and the detection circuit, the speaker module is connected to the detection circuit, the detection circuit is connected to the comparison circuit, and the comparison circuit is connected to the audio power amplifier module.

[0028] The output end of the audio power amplifier module transmits an output current (Iout) to the speaker module, and transmits an output voltage (Vout) to the detection circuit and the speaker module, and the comparison circuit sends a feedback signal to the audio power amplifier module. The computer device collects the output current and the output voltage, and determines the number of speakers according to the output current and the output voltage.

[0029] Step 102: Determine the system channels based on the number of speakers.

[0030] In an embodiment of the present invention, the system channels include at least one of a 2.0 channel, a 2.1 channel, a 4.0 channel, a 4.1 channel, a 5.1 channel, a 5.1.2 channel, a 7.1 channel, and a 7.1.4 channel.

[0031] Step 103: Determine target sound effect parameters based on the number of speakers and system channels.

[0032] In an embodiment of the present invention, Fig. 3 is a schematic diagram of a parameter matching module according to an embodiment of the present invention, the parameter matching module shown in Fig. 3 is installed in a computer device, and a plurality of sound effect parameters are pre-stored in the parameter matching module, and the computer device determines a target sound effect parameter from the plurality of sound effect parameters according to the number of speakers and the system channels.

[0033] In an embodiment of the present invention, a channel determination method is provided, in which the number of speakers is determined according to the acquired output current and output voltage, a system channel is determined according to the number of speakers, and a target sound effect parameter is determined according to the number of speakers and the system channel. Since high-level, mid-level and low-level computer devices respectively correspond to different sound effect parameters, after the computer device determines the number of speakers, the sound effect parameters of the computer device can be determined based on the number of speakers, and the high-level, mid-level or low-level configuration of the computer device can be realized. This eliminates the need for manufacturers to develop speaker systems multiple times, thereby reducing the design costs of manufacturers developing speaker systems, and saving human resources and research and development resources.

[0034] FIG. 4 is a flow chart of another channel determination method according to an embodiment of the present invention. As shown in FIG. 4, the method includes the following steps:

[0035] Step 201: Generate at least one load resistance value based on collected output current and output voltage.

[0036] In an embodiment of the present invention, as shown in FIG. 2, the output end of the main chip transmits a detection signal to the audio power amplifier module. The input end of the audio power amplifier module receives the detection signal transmitted from the main chip, and the output end of the audio power amplifier module transmits an output voltage to the speaker module and the detection circuit, and transmits an output current to the speaker module. The input end of the speaker module receives the output current transmitted from the audio power amplifier module, and the output end of the speaker module transmits the output current to the detection circuit, so that the detection circuit in the loop can recognize the output current independently. The detection circuit further transmits the detected output current to the comparison circuit. The comparison circuit includes a plurality of detection circuits, each of which checks the output current, and each of which is connected to a speaker in the speaker module, to obtain the impedance value of each speaker in the speaker module.

[0037] Step 202: Determine the number of speakers based on at least one load resistance value.

[0038] In an embodiment of the present invention, the computer device calculates a valid number of load resistance values ​​that are within at least one valid threshold range based on at least one load resistance value and the valid threshold range, and determines the valid number as the number of speakers.

[0039] As shown in FIG. 2, the comparison circuit sends a feedback signal to the audio power amplifier module, the feedback signal includes at least one load resistance value, the audio power amplifier module selects at least one load resistance value within the effective threshold range, the audio power amplifier module sends a status signal to the main chip, the status signal includes at least one load resistance value within the effective threshold range, the main chip calculates the effective number of the load resistance values ​​within the effective threshold range, and the effective number is the number of speakers. For example, the resistance value of a speaker is usually greater than 2Ω and less than 32Ω, so if the load resistance value is greater than 32Ω, it indicates that the output end of the audio power amplifier module is open, if the load resistance value is greater than 2Ω and less than 32Ω, it indicates that the speaker module includes at least one speaker, and if the load resistance value is less than 2Ω, it indicates that the speaker module is in a short-circuit state. Therefore, the effective threshold range can be the range in which the load resistance value is greater than 2Ω and less than 32Ω, and if the status signal received by the main chip includes four load resistance values ​​greater than 2Ω and less than 32Ω, it indicates that the computer device includes four speakers.

[0040] Step 203: Determine a system channel based on the number of speakers and the acquired first channel.

[0041] In an embodiment of the present invention, the first channel is a channel of a preset speaker. The determined system channel is a channel available to the computer device. The first channel may include at least one of a 2.0 channel, a 2.1 channel, a 4.0 channel, a 4.1 channel, a 5.1 channel, a 5.1.2 channel, a 7.1 channel, and a 7.1.4 channel. As shown in FIG. 3, the first channel is stored in the computer device, and the computer device determines the system channel from the first channel based on the number of speakers. If the computer device has only two speakers, the system channel may be a 2.0 channel, and if the computer device includes four speakers, the system channel may be a 2.0 channel and a 4.0 channel.

[0042] Step 204: Retrieve at least one sound effect parameter based on the number of speakers and the system channels.

[0043] In an embodiment of the present invention, the target sound effect parameters include at least one of a tonal equalizer parameter, an automatic linear distortion correction parameter, a bass enhancement parameter, a stereo widening parameter, and a dynamic range control parameter.

[0044] The computer device stores a plurality of sound effect parameters. Each sound effect parameter is adjusted according to a different number of speakers and a system channel, and can ensure that the optimal sound quality of the speaker is reproduced under the number of speakers and the system channel. The computer device includes a digital signal processing (DSP) chip, and an operator can add the correspondence between the number of speakers, the system channel and the target sound effect parameter to the DSP chip in advance. The computer device searches for at least one sound effect parameter based on the correspondence between the preset number of channels and the sound effect parameters. As shown in FIG. 3, when the number of speakers is four and the system channels are 2.0 channels and 4.0 channels, the computer device searches for the sound effect parameters corresponding to the four speakers and the 2.0 channels, and searches for the sound effect parameters corresponding to the four speakers and the 4.0 channels.

[0045] Step 205: Determine a target sound effect parameter from the at least one sound effect parameter based on the priority of the sound effect parameters.

[0046] In an embodiment of the present invention, the computer device may store a priority order of the sound effect parameters in advance. The priority order of the sound effect parameters may be determined according to the quality of the output sound quality. For example, as shown in FIG. 3, the computer device searches for sound effect parameters corresponding to four speakers and 2.0 channels, and searches for sound effect parameters corresponding to four speakers and 4.0 channels. However, the sound quality of the sound output by the computer device based on the sound effect parameters corresponding to four speakers and 4.0 channels is higher than the sound quality of the sound output by the computer device based on the sound effect parameters corresponding to four speakers and 2.0 channels, so the priority order of the sound effect parameters corresponding to four speakers and 4.0 channels is higher than the priority order of the sound effect parameters corresponding to four speakers and 2.0 channels, and the computer device determines that the target sound effect parameters are the sound effect parameters corresponding to four speakers and 4.0 channels.

[0047] The computer device plays back the sound based on the determined target sound effect parameters, so that the computer device can output optimal sound effects and achieve optimal sound effect effects. In addition, when the user's requirements for sound quality are improved, the user can meet the requirements for sound quality without replacing the computer device or the speaker system of the computer device, and the computer device can determine higher quality sound effect parameters by increasing the number of speakers of the computer device.

[0048] The present invention provides a channel determination method, in which the number of speakers is determined according to the acquired output current and output voltage, a system channel is determined according to the number of speakers, and a target sound effect parameter is determined according to the number of speakers and the system channel, thereby realizing high-level, mid-level and low-level arrangements of a computer device by setting different numbers of speakers, reducing the design cost for manufacturers to develop speaker systems, increasing the scalability of sound reproduction, and enhancing product differentiation. At the same time, there is no need to set sound effect parameters for each type of computer device, saving human resources and research and development resources, and increasing the possibility and convenience of users' subsequent personalized upgrade of their speaker systems, and meeting the needs of users for sound quality without replacing computer devices or speaker systems.
