The power management module 1 includes a first power supply terminal 51, a second power supply terminal 52, a battery charging and discharging terminal 54 and a first detection terminal 53, the first power supply terminal 51 is connected to the audio processing module 1 and the first interface 2, the second power supply terminal 52 is connected to the second interface 3, the battery charging and discharging terminal 54 is connected to the battery module 6, the first detection terminal 53 is connected to the control module 4, and the power management module is configured to: detecting the control signal output by the control module 4 through the first detecting terminal 53, if it is detected that the control signal is a first preset signal when the first power supply terminal 51 is in a non-output state, controlling itself to enter a fast charging protocol shutdown mode to start performing non-fast charging protocol power supply (i.e. normal charging, where the power supply voltage is a standard voltage of about 5V) on the audio processing module 1 and the external device connected to the first interface 2 through the first power supply terminal 51, so as to start the audio processing module and simultaneously supply power to the external device connected to the first interface 2, if it is detected that the control signal is a second preset signal when the first power supply terminal 51 is in a non-output state, communicating with the second external device to determine whether the second external device has a fast charging protocol power supply mode, if the second external device has a fast charging protocol power supply mode, the first power supply terminal 51 is controlled to continuously maintain the no-output state and to enter the fast charging protocol starting mode, the fast charging protocol power supply with the second external device connected to the second interface 3 is realized through the second power supply terminal 52, and if the second external device does not have the fast charging protocol power supply mode, the non-fast charging protocol power supply with the second external device connected to the second interface 3 is realized through the second power supply terminal 52. Through the power supply mode, the power supply of the quick charging protocol between the external audio processing device and the second external equipment connected to the second interface 3 can be realized, and the damage to the audio processing module caused by the output larger voltage when the power management module is quickly charged can also be avoided.
Wherein, the power management module 5 can interact with a second external device connected to the second interface 3 to determine whether the second external device has a fast charging protocol charging mode, specifically, when the power management module 5 determines that the second external device connected to the second interface 3 supports the fast charging protocol possessed by the power management module 5, a fast charging operation can be performed between the power management module 5 and the second external device connected to the second interface 3, when it determines that the connected second external device does not support the fast charging protocol possessed by the power management module 5, the power management module 5 and the external device connected to the second interface 3 are charged in a non-fast charging protocol charging mode, specifically, the power supply voltage is a standard voltage (such as about 5V, i.e. normal charging), when the power management module 5 enters the fast charging protocol closing mode, the fast charging function of the power management module 5 is in a closing state, no matter whether the second external equipment connected in has the charging mode of the quick charging protocol or not, the second external equipment is charged only in the power supply mode of the non-quick charging protocol. Specifically, the power supply voltage between the two is a standard voltage (e.g., about 5V, i.e., common charging), that is, when entering the fast charging protocol shutdown mode, the power management module 5 is prohibited from performing fast charging, but only the common charging is performed.
It can be understood that, for the same second external device, if the second external device supports the fast charging protocol of the power management module 5, the charging speed of the power management module in the fast charging protocol on mode is faster than the charging speed of the power management module in the fast charging protocol off mode;
for example, the power management module 5 may have a fast charge protocol that includes one or more of the following: PD rapid charging protocol and QC rapid charging protocol.
For example, in an embodiment of the present invention, the power management module 5 may include a power management chip with a single inductance scheme, that is, the power management chip supports only one voltage output at the same time (that is, the voltages of the power supply terminals of the power management chip at the same time are the same), and when the first power supply terminal 51 is in a no-output state, if the power management chip detects that the control signal output by the control module is the first preset signal, the power management chip controls itself to enter the fast charging protocol shutdown mode, and starts to supply power to the audio processing module and the first external device connected to the first interface 2 through the first power supply terminal in the non-voltage power supply mode, so that the first external device connected to the first interface 2 can be supplied with power while performing audio interaction with the audio processing module 1, it should be noted that, if the second interface 3 is also connected to the second external device at this time, since the power management module 5 has entered the fast charging protocol shutdown mode, the power supply voltage between the power management module 5 and the external device connected to the second interface 3 is the standard voltage (e.g., about 5V) regardless of whether the external device connected to the second interface 3 supports the fast charging protocol of the power management module 5.
When the first power supply terminal 51 is in a non-output state, if the power management chip of the single-inductor scheme detects that the control signal output by the control module 4 is a second preset signal, the power management chip controls the first power supply terminal 51 to continuously maintain the non-output state and controls itself to enter a fast charge protocol start mode, in this mode, when the power management chip recognizes that the second external device connected to the second interface 3 supports the fast charge protocol power supply mode, the power management chip and the second external device connected to the second interface 3 can perform fast charge operation, and because the first power supply terminal 51 continuously maintains the non-output state, the audio processing module is not damaged by the fast charge large voltage output by the power management chip.
In the external audio processing apparatus provided in the embodiment of the present invention, the power management module performs corresponding control on a power supply mode and a power supply terminal state of the power management module according to a control signal output by the control module, and when the first power supply terminal is in a non-output state (i.e., when the audio processing module is in an off state), if it is detected that a control signal output by the control module is a first preset signal (i.e., an on signal of the audio processing module), the power management module controls the power management module to enter a fast charging protocol off mode, so as to implement audio interaction between the external device and the audio processing module through the first interface and simultaneously supply power to the external device, if it is detected that the control signal output by the control module is a second preset signal, it is determined whether the second external device has the fast charging protocol power supply mode, and if it has, the first power supply terminal is controlled to continuously maintain the non-output state and control the power management module to enter the fast charging protocol on mode, the power supply of the fast charging protocol between the second external equipment connected with the second interface is realized through the second power supply end, if the power supply of the fast charging protocol is not realized, the power supply of the non-fast charging protocol between the second external equipment connected with the second interface is realized through the second power supply end, so that the fast charging operation can be realized through the second interface, and meanwhile, the audio processing module is prevented from being damaged by fast charging large voltage.
The external audio processing device in the embodiment of the invention can be an external sound card;
in the embodiment of the present invention, the external audio processing device further includes a battery module 6 connected to the battery charging and discharging terminal 54 of the power management module 5, and the power management module 5 is further configured to perform charging and discharging management on the battery module 6. For example, the power management module 5 may use the second external device connected to the second interface 3 as a power input to charge the built-in battery module 6, or may use the built-in battery module 6 as a power input to supply power to each power consuming component in the external sound card (for example, including supplying a standard voltage to the audio processing module 1) and/or supply power to the second external device connected to the second interface 3.
