In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the following is a detailed description of the preferred embodiments of the present invention with reference to the accompanying drawings.

Detailed Implementation

[0016] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. It should be noted that references to "an embodiment," "embodiment," "example embodiment," etc., in this specification refer to the described embodiment including specific features, structures, or characteristics; however, not every embodiment must include these specific features, structures, or characteristics. Furthermore, such expressions do not refer to the same embodiment. Moreover, when describing specific features, structures, or characteristics in conjunction with embodiments, whether or not explicitly described, it is indicated that incorporating such features, structures, or characteristics into other embodiments is within the knowledge scope of those skilled in the art.

[0017] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0018] In some embodiments, such as Figure 1 The diagram illustrates a horn power adaptive system, comprising a horn insertion detection module and a near-field communication detection module. The horn insertion detection module detects whether a target horn is inserted; if so, it activates the near-field communication module. The near-field communication detection module reads the horn parameters of the target horn after insertion. The near-field communication detection module is positioned at the insertion location of the target horn, and the horn parameters include horn impedance, horn power, and horn EQ parameters. The horn insertion detection module also controls the operation of the target horn based on its horn parameters.

[0019] The speaker insertion detection module includes a speaker insertion detection plug and a speaker insertion detection circuit. The speaker insertion detection plug is used to detect whether the target speaker is connected. The speaker insertion detection circuit is used to detect whether the target speaker is inserted; if so, the near-field communication module is activated. The near-field communication detection module includes a near-field communication tag and a near-field communication reading module. The near-field communication tag is integrated on the target speaker and is used to store the speaker parameters of the target speaker. The near-field communication reading module is integrated at a preset position on the target speaker and is used to read the speaker parameters of the target speaker and send the speaker parameters to the speaker insertion detection circuit.

[0020] The preset position of the target speaker can be on the speaker socket into which the target speaker is inserted.

[0021] For example, such as Figure 2-3 As shown, Figure 2 This is a schematic diagram of the structure for inserting the detection plug. Figure 3 The circuit diagram for the speaker insertion detection circuit, wherein, Figure 3 J1 is the female speaker connector. The speaker can be inserted into the test plug "pin to pin" into the female speaker connector. Figure 3 Pins 1 and 2 of the connector correspond to the negative and positive terminals of SPK_N and SPK_P, respectively, in the speaker insertion detection plug. Figure 3 Pins 3 and 4 correspond Figure 2 106 and 107 are in the diagram. R1 is a pull-down resistor; it is used when the "speaker insertion detection plug" is inserted. Figure 3 The 3rd and 4th in the middle will be together Figure 2 106 and 107 are connected together, and then 106 and 107 are connected through... Figure 3 103 in the middle is connected together to realize that "GPIO1 is pulled down when the speaker is inserted and pulled up by default when the speaker is not inserted". It can detect whether the speaker is inserted by detecting whether GPIO1 is pulled down. When the insertion detection circuit detects that the target speaker has been inserted into the preset position, the near-field communication tag installed on the target speaker and the near-field communication reading module installed on the speaker insertion detection plug are attached together. The near-field communication reading module can read the speaker parameters of the target speaker carried on the near-field communication tag and send the speaker parameters of the target speaker to the speaker insertion detection circuit. Since the speaker insertion detection circuit contains a main control unit, the main control unit can calculate the voltage that can be output to the target speaker based on the speaker impedance and speaker power. The calculation formula is as follows (1): (1) Among them, V toprms Where P is the upper limit of voltage, P is the speaker power, and R is the speaker impedance.

[0022] Since the initial output voltage of the speaker insertion detection circuit to the target speaker is the minimum voltage, it is also necessary to calculate the voltage to be increased to the target speaker. The calculation formula is as follows (2): (2) Where N is the power amplifier gain of the speaker insertion detection circuit, X is the voltage to be boosted, and V toprms V is the upper limit of voltage. DACminrms This represents the minimum output voltage of the DAC.

[0023] It should be noted that when X is negative, it means that the minimum voltage of the speaker insertion detection circuit is already greater than the upper limit of the target speaker's voltage. The target speaker is not compatible with this speaker power adaptive system, so no voltage will be output to the target speaker. When X is positive, X is increased based on the minimum voltage. Based on X, the output voltage of the maximum DAC is controlled, which is the maximum volume, thus controlling the speaker's operation. At this time, based on the speaker's EQ parameters, the speaker outputs different modes of sound.

[0024] The speaker power adaptive system in the above embodiment includes a speaker insertion detection module and a near-field communication detection module. The speaker insertion detection module is used to detect whether the target speaker is installed in a preset position. The near-field communication detection module is used to read the speaker parameters of the target speaker after the target speaker is installed in the preset position. The speaker parameters include speaker impedance, speaker power, and speaker EQ parameters. The speaker insertion detection module is also used to control the operation of the target speaker according to the speaker parameters. By automatically detecting speaker parameters through the near-field communication detection module and controlling the speaker operation according to the speaker parameters, the system can generate power suitable for the speaker of any power, thereby controlling the speaker operation. This not only eliminates the need to replace the power amplifier but also avoids the risk of equipment damage caused by replacing the speaker, significantly improving the applicability to different speaker models.

[0025] In another embodiment, such as Figure 4 The diagram shows a flowchart of a speaker power adaptive method, which includes the following steps: S101, when the target speaker is detected to be inserted and installed in the preset position, determine whether the near-field communication tag is activated.

[0026] Specifically, the near-field communication detection module needs to be activated when the target speaker is detected to be inserted and installed in the preset position.

[0027] S102, if the near-field communication tag has been activated, determine whether the speaker parameters of the target speaker are in a preset format.

[0028] S103, if the speaker parameters are in a preset format, then obtain the speaker parameters of the target speaker.

[0029] The speaker parameters include speaker impedance, speaker power, and speaker EQ parameters.

[0030] Specifically, when the target speaker is detected to be installed in a preset position, and the near-field communication tag is activated, and the speaker parameters are in a preset format, the speaker impedance, speaker power, and speaker EQ parameters of the target speaker are obtained using near-field communication (NFC).

[0031] S104, calculate the voltage to be increased for the target horn based on the horn impedance and the horn power.

[0032] Specifically, the upper limit of the voltage output to the target speaker is calculated based on the speaker impedance and the speaker power (refer to Formula 1); the voltage to be increased for the target speaker is determined based on the upper limit of the voltage, the minimum voltage, and the preset power amplifier multiple (refer to Formula 2).

[0033] S105, control the target speaker to work according to the voltage to be increased and the speaker EQ parameters.

[0034] Specifically, when the voltage to be boosted is negative, it means that the current minimum voltage value is already greater than the upper limit of the target speaker's voltage. The target speaker is not compatible with this speaker's power adaptive system, so no voltage will be output to the target speaker. When the voltage to be boosted is positive, the voltage to be boosted is increased based on the minimum voltage value. That is, the output voltage of the maximum DAC is controlled according to the voltage to be boosted, which is the maximum volume. At this time, according to the speaker's EQ parameters, the speaker outputs different modes of sound. After the above process is completed, the near-field communication detection module is turned off.

[0035] The speaker power adaptive method in the above embodiments first acquires the speaker parameters of the target speaker when it is detected that the target speaker has been inserted and installed in a preset position. The speaker parameters include speaker impedance, speaker power, and speaker EQ parameters. Then, the voltage to be boosted for the target speaker is calculated based on the speaker impedance and speaker power. Finally, the target speaker is controlled to operate based on the voltage to be boosted and the speaker EQ parameters. By automatically detecting speaker parameters through a near-field communication detection module and controlling the speaker operation based on these parameters, the system can generate a power suitable for the speaker of any power rating, thereby controlling the speaker operation. This not only eliminates the need to replace the power amplifier but also avoids the risk of equipment damage caused by replacing speakers, significantly improving the applicability to different speaker models.
