Specifically, when the earphone management module 12 detects that the wireless communication device is in the earphone In mode, when the audio type is ringtone, set the first ringer volume to the headphone volume, or when the audio type is alarm, set the first alarm volume to the headphone volume, or set the first multimedia volume to the earphone when the audio type is multimedia. volume.

The working principle of the first embodiment of the mobile communication device of the present invention is as follows:

(1) Headphone status detection, continue to refer to Figure 2:

The earphone management module 12 manages and detects the state of the earphone. When the earphone is inserted into the mobile communication device, a hardware interrupt is generated. The hardware circuit detects the earphone insertion state through a hardware pin such as a GPIO pin. When the earphone is inserted, the hardware tube is inserted. A high level is generated on the foot PIN pin. When the earphone is pulled out, a low level is generated on the PIN pin; when a level change is detected on the PIN pin, a hardware interrupt is generated. After receiving the interrupt, the baseband chip 121 determines the type of the interrupt. When it is found that the insertion interrupt signal of the earphone, the relevant processing function of the hardware interrupt is called, and the earphone management module 12 is notified in the interrupt processing function that the earphone has been inserted, and the variable of the headphone state is recorded (boolean) Current_headset_on) is set to "TRUE"; when the earphone is unplugged from the mobile communication device, a hardware interrupt is also generated. After the baseband chip 121 receives the interrupt, it determines the type of the interrupt, and finds that the earphone is interrupted by the interrupt signal. The relevant processing function of the hardware interrupt notifies the earphone management module 12 that the earphone has been unplugged in the interrupt handling function of the earphone pullout, and sets the variable for recording the state of the earphone to "FALSE".

When the state of the headset changes, such as when the headset is inserted into the mobile communication device, the headset management module 12 notifies the volume control module 11 to distinguish and set the volume type, that is, when the headset is inserted, the volume control module 11 is notified of the current volume type. Switching to "Headphone Mode", when the headset is unplugged, the volume control module 11 is notified to switch the current volume type to "non-headphone mode".

(2) Volume type control:

The volume setting module 10 includes a plurality of volume setting items. In the volume setting item on the conventional mobile communication device, different audio types require volume setting, including: ringtone, alarm clock, multimedia, etc., and the volume is stored in a structured manner. In the file system of the mobile communication device, when the volume is set, the volume structure is stored in the corresponding position of the file system of the mobile communication device, so as to ensure that the value set by the user can be saved after the mobile communication device is turned off. At the same time, in order to facilitate the audio playing, when using the volume, the system of the mobile communication device reads the volume structure into the memory and assigns it to a structure variable (struct) Audio__volum_info Audio_Level), during the use of the mobile communication device, when the user resets the volume, the structure variable will be updated in time to achieve the same as the user settings.

The volume structure is added to the file system of the mobile communication device in order to achieve the independence of the headphone volume setting and other play modes, and the volume structure stores the volume value corresponding to the earphone, that is, different audio types, such as Ringtone, alarm, multimedia, volume played in headset mode. Thus, the file system will have two volume structures for storing the volume value, one corresponding to the volume value of the non-earphone, such as the speaker volume, that is, the "non-headphone mode" volume, and the other corresponding to the volume value of the earphone. That is, the "headphone mode" volume. When the earphone is plugged into the mobile communication device, the earphone volume is used, and when the earphone is not inserted in the mobile communication device, the non-headphone volume is used, thereby completing the separation of the volume type setting save.

In order to distinguish between the two volume usage types in the volume control module, an enumeration type variable is used to indicate the current volume category (ENUM_AUDIO_TYPE Current_aduio_type), the value of the variable is updated when the state of the headset changes, that is, after the headset is inserted into the mobile phone, the earphone module notifies the volume control module 11 to set the variable value to the volume of the earphone, and when the earphone module detects that the earphone is pulled out, the volume control is notified. Module 11 sets this variable to a non-headphone volume.

When the mobile communication device starts up, it will read the current volume value from the file system of the mobile communication device to the corresponding structure variable in the memory (struct) Audio__volum_info In Audio_Level), it is convenient to use when playing the volume. When the mobile communication device is powered on to initialize the volume variable, the headset state is first determined, that is, the headset state variable (boolean) in the headset management module 12. Current_headset_on) Get the current status of the headset. If the headset status is inserted into the mobile communication device, the current volume type (ENUM_AUDIO_TYPE) Current_aduio_type) is set to "Headphone Mode", and the corresponding headphone volume value in the file system is read, and the headphone volume value is assigned to the volume structure (struct Audio__volum_info Audio_Level); if the headset status is not inserted into the mobile communication device, the current volume type (ENUM_AUDIO_TYPE Current_aduio_type) is set to "non-earphone mode", and reads the corresponding non-headphone volume value in the file system, and assigns the non-headphone volume value to the volume structure (struct Audio__volum_info Audio_Level). In this way, after the mobile communication device is started, the volume state displayed in the setting item is consistent with the current headset state: when the headset is plugged in, the user interface of the setting item displays the volume of different audio types of the headset mode; When no headphones are plugged in, the volume of the different audio types of the non-headphone mode is displayed in the setting item user interface; and the volume value used by the mobile communication device when the sound needs to be played is also consistent with the state of the earphone, for example, when there is a headset When inserted, the playback volume value is the headphone volume; when no headphones are plugged in, the volume value of the playback is the non-headphone volume (such as the speaker volume).

The volume structure in the above-mentioned headphone mode is defined as the first group volume, and the volume structure in the non-earphone mode is defined as the second group volume.

In another embodiment of the present invention, the volume setting module 10 includes a first storage unit (not shown) and a second storage unit (not shown), and the volume control unit 11 further includes a first connection end (not shown) and a second connection end (not shown), the first storage unit is connected to the first connection end, the second storage unit is connected to the second connection end, the first storage unit is configured to store the first group volume, and the second storage unit is used to store the second connection unit Two groups of volume.

The volume control module 11 includes a third storage unit (not shown) for storing the headphone volume or for storing the non-headphone volume.

In the embodiment of the present invention, by adding the first and second storage units, the first group of volumes in the headphone mode can be stored, and the third storage unit is added. When the headphone mode is detected, the headphone volume is stored, and the non-headphone mode is detected. When storing non-headphone volume, it is convenient for storage.

Referring to FIG. 3, FIG. 3 is a flowchart of a first embodiment of a volume control method of a mobile communication device according to the present invention. The control method includes the following steps:

In step S1, in the headphone mode, different types of volume are set to the first group of volumes, and in the non-earphone mode, the volume of different audio types is set to the second group of volumes.

In step S2, it is detected whether the mobile communication device is in the headset mode or the non-headphone mode.

In step S3, when the headphone mode is detected, the volume of the application program is set to the first group volume in the headphone mode, and when the non-earphone mode is detected, the volume of the application program is set to the second group volume of the non-headphone mode.

In the embodiment of the present invention, the volume of different audio types is set to the first group volume when the headphone mode is set, and the volume of the different audio types is set to the second group volume when the non-headphone mode is set, and the application is detected when the headphone mode is detected. The volume is set to the first set of volume in the headset mode. When the non-earphone mode is detected, the volume of the application is set to the second set of volume in the non-earphone mode, which can achieve the best sound and protect the hearing in different playback environments.

In another embodiment of the present invention, in the above step S1, the method includes: storing the first group of volumes and storing the second group of volumes.

In another embodiment of the present invention, in the above step S3, the method includes: detecting an audio type, and setting a headphone volume according to an audio type or setting a non-earphone volume.

In general, when the headset mode or non-headphone mode is used, the default currently playing audio type is ringtone. Of course, you can set the default audio type as needed.

In another embodiment of the present invention, after detecting the audio type and setting the headphone volume according to the audio type or setting the non-headphone volume, the method includes: storing the headphone volume, or storing the non-headphone volume.

During the use of the mobile communication device, when the state of the headset changes, such as the mobile communication device is inserted into the headset, the headset management module acquires the headset state, and sets the corresponding headset state variable to “TRUE”, and simultaneously informs the volume control module to update. Volume type. The volume control module knows the current volume type (ENUM_AUDIO_TYPE) after the headset status changes. Current_aduio_type) is set to "Headphone Mode", and the display and volume value variables are updated in the volume setting item, that is, the value saved by the corresponding headphone volume in the file system is read, and the volume value of the read headphone is assigned to the volume variable (struct) Audio__volum_info Audio_Level), and refresh the status of the volume display in the setting item, and display it with the new volume value. In this way, the volume value in the setting item is automatically adjusted to the headphone volume value, that is, the volume value state displayed by the user interface is the headphone volume state, and at the same time, when the mobile communication device needs to play the sound, the volume value used is also adjusted to the headphone volume; When the headset is unplugged from the mobile communication device, the headset management module obtains the headset status and sets the corresponding headset status variable to "FALSE", while notifying the volume control module to update the volume type. The volume control module knows the current volume type (ENUM_AUDIO_TYPE) after the headset status changes. Current_aduio_type) is set to "non-headphone mode", and the display is updated and the volume value variable is updated in the volume setting module, that is, the value saved by the corresponding headphone volume in the file system is read, and the volume value of the read headphone is assigned to the volume variable. (struct Audio__volum_info Audio_Level), and refresh the status of the volume display in the volume setting module, and display it with the new volume value. In this way, the volume value in the volume setting module is automatically adjusted to the non-headphone volume, that is, the volume value state displayed by the user interface is the non-headphone volume state, and at the same time, the volume value used by the mobile communication device when the sound needs to be played is also adjusted to be non- Headphone volume.

Through the detection of the earphone by the earphone detection module, and when the state of the earphone is found to be changed, the volume control module is notified to switch the volume type, thereby ensuring the display of the volume in the mobile communication device and the volume variable value used by the mobile communication device and the currently used volume value. The status of devices such as headphones, speakers, etc. remains the same.

Referring to FIG. 6, FIG. 6 is a third flowchart of the first embodiment of the volume control method of the mobile communication device of the present invention.

When the user adjusts the volume, whether through the volume setting module or directly through the volume adjustment button, the volume control module first obtains the currently adjusted audio type, such as alarm clock, ringtone, multimedia, if it is through the user interface in the volume setting module. To make adjustments, the user interface in the volume setting module has corresponding setting items corresponding to different sound types; if the button is adjusted, according to the type of the currently playing sound, if no sound is playing, the ringer volume is adjusted by default, and then Convert the user's setting action into a volume value. For example, when the user increases the volume by pressing the button, each time the user presses the button, the corresponding value in the current volume structure variable is added with a level value (for example, from 50% to 60). %), refresh the display of the volume in the volume setting module according to the new volume value, and the new volume value according to the current volume type (ENUM_AUDIO_TYPE Current_aduio_type) is saved to the corresponding volume structure in the file system of the mobile communication device, that is, the volume setting value of the type is updated.
