[0036] To better understand the technical solution of the present invention, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0040] It should be understood that although terms such as first, second, third, etc., may be used to describe numbers in embodiments of the present invention, these numbers should not be limited to these terms. These terms are only used to distinguish numbers from each other. For example, without departing from the scope of embodiments of the present invention, a first number may also be referred to as a second number, and similarly, a second number may also be referred to as a first number.

[0041] Depending on the context, the word "if" as used here can be interpreted as "when," "when," "in response to determination," or "in response to detection." Similarly, depending on the context, the phrase "if determination" or "if detection (of the stated condition or event)" can be interpreted as "when determination," "in response to determination," "when detection (of the stated condition or event)," or "in response to detection (of the stated condition or event)."

[0042] Figure 1 A flowchart of a method for determining a vocal tract provided in an embodiment of the present invention is shown below. Figure 1 As shown, the method includes:

[0043] Step 101: Determine the number of speakers based on the obtained output current and output voltage.

[0044] The steps in the embodiments of the present invention can be executed by a computer device. The computer device includes, but is not limited to, a smart TV, external devices connected to a smart TV, or a smart TV and external devices.

[0045] In this embodiment of the invention, Figure 2 This is a schematic diagram of an intelligent detection module provided in an embodiment of the present invention, as shown below. Figure 2 As shown, Figure 2 The intelligent detection module shown is integrated into a computer device. The module includes a main chip, an audio power amplifier module, a speaker module, a detection circuit, and a comparison circuit. The main chip is connected to the audio power amplifier module, which in turn is connected to the speaker module and the detection circuit. The speaker module is also connected to the detection circuit, which in turn is connected to the comparison circuit, and the comparison circuit is connected to the audio power amplifier module.

[0046] The audio power amplifier module outputs an output current (Iout) to the speaker module and an output voltage (Vout) to the detection circuit and speaker module. The comparison circuit sends a feedback signal to the audio power amplifier module. The computer collects the output current and output voltage; based on the output current and output voltage, it determines the number of speakers.

[0047] Step 102: Determine the system channels based on the number of speakers.

[0048] In this embodiment of the invention, the system channel includes at least one of the following: channel 2.0, channel 2.1, channel 4.0, channel 4.1, channel 5.1, channel 5.1.2, channel 7.1, and channel 7.1.4.

[0049] Step 103: Determine the target sound effect parameters based on the number of speakers and system channels.

[0050] In this embodiment of the invention, Figure 3 This is a schematic diagram of a matching parameter module provided in an embodiment of the present invention, as shown below. Figure 3 As shown, Figure 3 The matching parameter module shown is mounted on a computer device and pre-stores multiple audio effect parameters. The computer device determines the target audio effect parameter from these multiple audio effect parameters based on the number of speakers and system channels.

[0051] This invention provides a method for determining audio channels. Based on the acquired output current and output voltage, the number of speakers is determined; based on the number of speakers, the system channels are determined; and based on the number of speakers and the system channels, the target sound effect parameters are determined. Since high-end, mid-range, and low-end computer equipment correspond to different sound effect parameters, after determining the number of speakers for the computer equipment, the sound effect parameters can be determined based on the number of speakers. This enables high-end, mid-range, or low-end configurations for computer equipment, eliminating the need for manufacturers to develop speaker systems multiple times, reducing the design cost of speaker system development, and saving human and R&D resources.

[0052] Figure 4 A flowchart of another method for determining the audio channel provided in an embodiment of the present invention is shown below. Figure 4 As shown, the method includes:

[0053] Step 201: Generate at least one load resistance value based on the collected output current and output voltage.

[0054] In embodiments of the present invention, such as Figure 2 As shown, the main chip's output sends a detection signal to the audio power amplifier module. The audio power amplifier module's input receives the detection signal from the main chip, and its output sends an output voltage to the speaker module and the detection circuit, and an output current to the speaker module. The speaker module's input receives the output current from the audio power amplifier module, and its output sends the output current to the detection circuit, allowing the detection circuit in the loop to automatically identify the output current. The detection circuit then sends the detected output current to a comparison circuit, which includes multiple detection circuits. Each detection circuit verifies the output current and is connected to a speaker in the speaker module to obtain the impedance value of each speaker in the speaker module.

[0055] Step 202: Determine the number of speakers based on at least one load resistance value.

[0056] In this embodiment of the invention, the computer device calculates the effective number of at least one load resistance value within the effective threshold range based on at least one load resistance value and an effective threshold range; the effective number is then used as the number of speakers.

[0057] like Figure 2 As shown, 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 filters out 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 counts the effective number of load resistance values ​​within the effective threshold range and uses this effective number as the number of speakers. For example, since the resistance of a speaker is typically greater than or equal to 2Ω and less than or equal to 32Ω, when the load resistance is greater than 32Ω, it indicates that the output of the audio power amplifier module is open-circuited; when the load resistance is greater than or equal to 2Ω and less than or equal to 32Ω, it indicates that the speaker module includes at least one speaker; when the load resistance is less than 2Ω, it indicates that the speaker module is short-circuited. Therefore, the effective threshold range can be a range where the load resistance is greater than or equal to 2 ohms and less than or equal to 32 ohms. When the status signal received by the main chip includes four load resistance values ​​greater than or equal to 2 ohms and less than or equal to 32 ohms, it indicates that the computer device includes four speakers.

[0058] Step 203: Determine the system channels based on the number of speakers and the first channel obtained.

[0059] In this embodiment of the invention, the first channel is a pre-defined speaker channel. The determined system channel is a channel usable by the computer device. The first channel may include at least one of channels 2.0, 2.1, 4.0, 4.1, 5.1, 5.1.2, 7.1, and 7.1.4. Figure 3 As shown, the computer device stores a first channel, and determines the system channel from the first channel based on the number of speakers. When the computer device includes only 2 speakers, the system channel is a 2.0 channel; when the computer device includes 4 speakers, the system channel can be either a 2.0 channel or a 4.0 channel.

[0060] Step 204: Based on the number of speakers and system channels, find at least one sound effect parameter.

[0061] In this embodiment of the invention, the target sound effect parameters include at least one of the following: timbre equalizer parameters, automatic linear distortion compensation parameters, bass enhancement parameters, stereo extension parameters, and dynamic range control parameters.

[0062] The computer device stores multiple audio effect parameters. Each parameter is calibrated for different numbers of speakers and system channels to ensure optimal sound quality for that specific configuration. The computer device includes a Digital Signal Processing (DSP) chip, allowing operators to pre-define the correspondence between speaker counts, system channels, and target audio effect parameters into the DSP chip. The computer device then uses this pre-defined correspondence to locate at least one audio effect parameter. For example... Figure 3 As shown, when the number of speakers is 4 and the system channels are 2.0 and 4.0, the audio parameters corresponding to the 4 speakers and the 2.0 channel are found, and the audio parameters corresponding to the 4 speakers and the 4.0 channel are also found.

[0063] Step 205: Determine the target sound effect parameter from at least one sound effect parameter according to the priority of the sound effect parameters.

[0064] In this embodiment of the invention, the priority of sound effect parameters can be pre-stored in the computer device. The priority of the sound effect parameters can be determined according to the output sound quality. For example, such as... Figure 3As shown, the computer device identifies the audio parameters corresponding to the four speakers and the 2.0 channel, and then identifies the audio parameters corresponding to the four speakers and the 4.0 channel. However, the sound quality output by the computer device based on the audio parameters corresponding to the four speakers and the 4.0 channel is higher than the sound quality output based on the audio parameters corresponding to the four speakers and the 2.0 channel. Therefore, the audio parameters corresponding to the four speakers and the 4.0 channel have a higher priority than the audio parameters corresponding to the four speakers and the 2.0 channel. The computer device then determines the target audio parameters to be those corresponding to the four speakers and the 4.0 channel.

[0065] Computer equipment plays sound according to the determined target sound effect parameters, thereby outputting the optimal sound effect and achieving the best sound quality. Furthermore, when users increase their demands for sound quality, they do not need to replace the computer equipment or its speaker system to meet their requirements; they can simply increase the number of speakers in the computer equipment to allow it to determine even better sound effect parameters.

[0066] This invention provides a method for determining audio channels. Based on the acquired output current and output voltage, the number of speakers is determined; based on the number of speakers, the system channels are determined; and based on the number of speakers and the system channels, the target sound effect parameters are determined. Thus, by equipping different numbers of speakers, high-end, mid-range, or low-end configurations of computer equipment are achieved, reducing the design cost for manufacturers developing speaker systems, increasing the scalability of sound playback, enhancing product differentiation, and eliminating the need to set sound effect parameters for each model of computer equipment, saving human and R&D resources. Furthermore, it increases the possibility and convenience for users to personalize and upgrade the speaker system later, allowing users to meet their sound quality requirements without replacing their computer equipment or speaker system.

Figure 5 As shown, the device includes: a first determining module 11, a second determining module 12 and a third determining module 13.
