Abstract

PURPOSE: A sound mode control method of a mobile communication terminal is provided to automatically change a sound value which has been previously set for an external unit by sensing mounting of the external unit. CONSTITUTION: Various sound modes are previously set(S1). Whether an external unit is mounted or separated is checked on the basis of a signal of a specific port of a terminal(S2,S3). If an external unit is mounted, a current mode is stored as a previous mode(S4) and a currently mounted external unit mode is activated as a current mode(S5). When a call is received, a reproduced sound is externally outputted in the corresponding mode(S6). If the external unit is separated, the stored previous mode is activated as a current mode(S7). When a call is received, a sound is outputted in the corresponding mode(S8).

Description

CONTROL METHOD FOR SOUND MODE OF MOBILE TELECOMMUNICATION TERMINAL EQUIPMENT}

The present invention relates to a technology for automatically changing the sound-related setting value of the mobile communication terminal, and in particular, when the external device is mounted on the terminal, the mobile communication terminal to be automatically changed to the preset sound-related setting value suitable for the external device It relates to a sound mode control method of the.

In general, a sound-related setting value in a mobile communication terminal such as a mobile phone means a value for controlling a bell, a lamp, a vibration, a silence, and the like. That is, it refers to a control value for determining the type of ring tone to be ringed when a call is received from the other party, the ringing volume, a display method and sound to indicate that a short message has arrived, and the volume to be sounded when the keypad is pressed.

In the sound mode control technology of the conventional mobile communication terminal, the user sets the "normal mode", "quiet mode", "meeting mode", "street mode", etc. in advance so as to suit the usage environment, and activates the setting values. By using the or button, the current mode is changed to one of them.

However, in the conventional sound mode setting method, a case in which an external device such as a headset or a car kit is mounted is not considered, which causes inconvenience in using them. For example, if the headset is mounted while a mode used in a quiet environment (such as conference mode) is activated, the volume level of the headset is set very low, and you must readjust it to a higher volume level to hear the call. There was a problem that can be easily recognized.

Therefore, an object of the present invention is to set the sound-related settings of the terminal body and the sound settings for the external device such as a headset or a car kit in advance, and detects that the external device is mounted to the sound-related settings to the corresponding value. The present invention provides a sound mode control method of a mobile communication terminal to be automatically changed.

S1-S8: Steps 1-8

A sound mode control method of a mobile communication terminal according to the present invention includes: a first process of monitoring an external device attached or detached from a terminal after setting a volume level and a sound type for each sound mode; If the external device is mounted, storing a currently activated mode as a previous mode and activating a mode of the currently mounted external device as the current mode; When the external device is separated, a third process of activating the stored previous mode to the current mode is described in detail with reference to FIGS. 1 and 2 attached to the sound mode control method of the present invention. .

In the present invention, the sound setting value is automatically changed by detecting that an external device such as a headset or a car kit is mounted on the main body of the mobile communication terminal. For example, a process of changing the sound value according to the mounting / dismounting of the headset will be described. .

First, preset various sound modes. For example, the silent mode sets the volume level to "0", the sound form to "vibration", the normal mode sets the volume level to "3", the sound form to "school class song", and the conference mode. Set the volume level to "2", the sound type to "Arirang song", the street mode to "4", the sound type to "techno", and the headset mode to "4". In this case, the sound type is set to "Gun-Bam-Ryeong-Song", respectively, and the current mode is set to one of them (eg, conference mode). (S1)

Thereafter, the terminal confirms that the external device is mounted or disconnected based on a signal of a specific port (for example, the GPIO PIN of the MSN chip in the case of the CDMA terminal) (S2, S3).

If it is determined that the external device (for example, a headset) is mounted, the currently activated conference mode is stored as the previous mode, and the currently mounted headset mode is activated as the current mode. Therefore, when a call is received from the other party from this time, the Gumbalyung song is reproduced at the volume level "4", and the sound signal thus reproduced is output to the outside through the headset. Accordingly, the user may recognize that the call is output from the outside by recognizing that the song is output through the headset. (S4-S6)

Thereafter, the external device is checked to be mounted or disconnected. If the headset is found to be disconnected, the stored previous mode (meeting mode) is activated as the current mode. Therefore, when a call is received from the other party from this time, the Arirang song is reproduced and output at the volume level "4". (S7, S8)

On the other hand, when there are two or more external devices, the sound setting values are automatically changed according to the priority of the external device. FIGS. 1A to 1D show two external devices (eg, a headset, In the case where the kit is used and the priority of the car kit is higher than the priority of the headset, a mode change example according to mounting / dismounting of an external device is shown. Here, since there is only one storage mode, when two external devices are mounted in succession, only one previous mode can be stored.

First, Figure 1 (a) shows a mode change example according to the mounting of the car kit (Car kit). If the kit is mounted while the current kit mode is activated, the new mode is not activated and the previous mode is not stored, regardless of whether the headset is mounted or removed. When the kit is mounted while the headset mode is currently activated, the kit mode is newly activated regardless of the mounting or detaching of the headset, and the headset mode is stored as the previous mode according to the mounting or detaching of the headset. If a kit is mounted while another mode (eg normal mode, conference mode) is currently active, the new kit mode will be activated regardless of whether the headset is mounted or removed. The other mode is saved as the previous mode.

In addition, Figure 1 (b) shows an example of mode change according to the separation of the kit. If the kit is removed while the previous mode is stored in the khaki mode, the headset mode or the normal mode is newly activated according to the mounting or detachment of the headset, and the normal mode is stored as the previous mode. If the kit is removed while the previous mode is in the headset mode, the headset mode or the normal mode is newly activated according to the mounting or detachment of the headset, and the normal mode is saved as the previous mode. If the kit is disconnected while the previous mode is stored in another mode (eg, normal mode, conference mode), the headset mode or another mode is newly activated according to the mounting or detachment of the headset, and the other mode is saved as the previous mode.

(C) and (d) of FIG. 1 show a newly activated mode and a previous mode stored according to the mounting / dismounting of the headset. This is similar to the principle of (a) and (b) of FIG. Will be omitted.

As described in detail above, the present invention automatically converts the current sound mode into a sound mode suitable for the external device and automatically returns to the original sound mode when the external device is mounted in the mobile communication terminal. There is an effect that the terminal can be used conveniently regardless of the installation / detachment of the external device. In particular, there is an effect that can easily recognize the fact that the call is received regardless of the installation / detachment of the external device.
