Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mobile communication device having an incoming call notification function for notifying a user of an incoming call by ringing a ring tone or displaying a lamp when a mobile phone or the like is received.
[0002]
[Prior art]
In the conventional mobile communication device of this type, when an incoming call is received, a lamp such as an LED is turned on or blinked, and at the same time, a ringing tone such as a melody sound is sounded. It was only to inform the user. That is, conventionally, as a technique for notifying that an incoming call has been received, a technique for lighting or blinking a lamp and a technique for sounding a ringtone are merely applied to a mobile communication device such as a mobile phone.
[0003]
For this reason, the lighting or blinking of the lamp and the ringing of the ringtone have no relation, and the lamp always lights or blinks in a uniform manner when receiving an incoming call, and this state is the case where the ringtone sounds simultaneously. But it was the same. Further, even when the configuration is combined with the vibration by the vibrator, the vibrator only vibrates at a fixed timing regardless of the ringing sound at the time of the incoming call.
[0004]
On the other hand, although it is not directly related to this type of mobile communication device, a technique regarding a method of blinking a light emitting member at a constant timing every cycle in synchronization with a cycle of melody reproduction is, for example, actual fair 8-1513. It is disclosed in the gazette.
[0005]
An example of a conventional portable communication device to which the disclosed technique is applied is shown in the block diagram of FIG. This conventional portable communication device has a light emission output unit 101, an LED drive unit 102, a melody reproduction unit 103, a control unit 104, a key operation unit 105, and a wireless communication unit 106 as basic components. The light emission output unit 101 includes a plurality of LEDs 111 to 113 serving as light emission output destinations, and these LEDs 111 to 113 are each supplied with a drive current from the LED drive unit 102 to emit light. Of the LEDs 111 to 113, the incoming LED 111 blinks when an incoming call is received. The liquid crystal backlight LED 112 is lit to illuminate the liquid crystal display unit when various operations are performed at the key operation unit 105 or when an incoming call is received. The key LED 113 illuminates the key itself of the key operation unit 105 when performing various operations on the key operation unit 105.
[0006]
The control unit 104 includes a key recognition unit 145, which recognizes a key operation by the key recognition unit 145 based on a key operation signal from the key operation unit 105 and outputs a key lighting control signal 141. In addition, an incoming call control unit 146 is provided, and based on the received signal output from the wireless communication unit 106, the incoming call control unit 146 recognizes the incoming call state and outputs an incoming call lighting control signal 142.
[0007]
The LED driving unit 102 includes an incoming LED driving unit 121, a liquid crystal backlight driving unit 122, and a key LED driving unit 123. By these driving units 121 to 123, an incoming LED 111, a liquid crystal backlight LED 112, Each key LED 113 is turned on or blinked. The melody reproduction unit 103 reproduces a melody sound such as a ringtone when receiving a call or when necessary. When the melody sound is reproduced and output, a sound control signal 144 is communicated with the incoming call control unit 146 of the control unit 104. , And an incoming lighting control signal 143 is output to the incoming LED driving unit 121 of the LED driving unit 102. When the LEDs 111 to 113 are lit, the drive signals 124, 125, and 126 are output from the respective driving units 121 to 123 in the LED driving unit 102 based on the key lighting control signal 141 and the incoming lighting control signals 142 and 143.
[0008]
In the above conventional example, when there is an incoming call, the incoming call control unit 146 of the control unit 104 recognizes the incoming call control signal 142 to the liquid crystal backlight drive unit 122 and the key LED drive unit 123 of the LED drive unit 102. By outputting, the liquid crystal backlight LED 112 and the key LED 113 are turned on. In addition, the incoming light lighting control signal 143 is output from the melody reproducing unit 103 to the incoming LED driving unit 121, thereby causing the incoming LED 111 to blink. In this case, simultaneously with the reproduction of the ring tone by the melody reproduction unit 103, the incoming LED 111 is blinked at a constant timing every cycle in synchronization with the melody reproduction cycle. Further, when a melody sound is reproduced by the melody reproducing unit 103 at a time other than when the incoming call is received, it is also possible to cause only the incoming LED 111 to blink at a constant timing every period in synchronization with the melody reproduction period.
[0009]
[Problems to be solved by the invention]
As described above, in the mobile communication device of the conventional example, the incoming LED 111 is always blinked at a fixed timing every cycle in synchronization with the cycle of melody playback. Even when is played, it always flashes in a uniform manner.
[0010]
However, recently, since the melody sound of the ringtone has progressed day by day and the like, it is preferable that the LED lighting at the time of the incoming call can be blinked in various patterns like the melody sound. For example, there is a request from a user such as making the appearance of an incoming call vivid or differentiating by an LED lighting method different from others. If the manner of blinking of the LEDs is conventional as in the conventional case, it is not possible to respond to various requests and usage situations of the user, and it is not interesting.

In this case, the sound pressure of the melody sound to be reproduced is detected by the sound pressure detection unit 37, and the melody reproduction control signal 31 is output to the control unit 4 when a sound pressure equal to or higher than a preset specified value is detected. Then, the light emission control units 45 to 47 of the control unit 4 generate and output melody synchronization lighting control signals 42 to 44 based on the melody reproduction control signal 31, and the driving units 21 to 23 of the LED driving unit 2 respectively melody synchronization lighting. Based on the control signals 42 to 44, drive signals 24 to 26 are generated and supplied to the LEDs 11 to 13 of the light emission output unit 1, respectively, and the LEDs are driven to blink.
[0057]
As described above, in the present embodiment, when playing a melody such as a ringtone, a melody sound is generated when the volume level exceeds a predetermined value according to the sound pressure (playback volume level) of the melody sound being played. It is possible to blink each LED in conjunction with each other.

【The invention's effect】
As described above, according to the present invention, the blinking timing, blinking color, etc. of the light emitting element for lighting notification can be varied, such as interlocking with the sound of the melody sound reproduced by the melody reproducing means at the time of incoming call. There is an effect of providing a portable communication device that can be changed.
