FIG. 1 is a front view showing an appearance of a mobile phone 20 as a portable electronic device according to the present embodiment. FIG. 2 is a block diagram showing a schematic configuration of the mobile phone 20. The mobile phone 20 includes a main control unit 211, a data storage unit 212, a wireless communication unit 213, an operation unit 214, a display unit 215, a detection unit 216, and a sound output unit 217. The mobile phone 20 is also provided with a clock unit 218 made up of, for example, an RTC (real time clock).

  The main control unit 211 includes a system bus, CPU, RAM, ROM, and the like, and performs various data processing and controls each unit based on an OS (operation system) and application programs. When the detection unit 216 detects an acceleration larger than a predetermined threshold during the output period of the preceding sound output from the sound output unit 217, the main control unit 211 continues to output the preceding sound. It is also used as a control means for controlling the sound output unit 217 so as to continuously output subsequent sounds.

  The data storage unit 212 includes a RAM as an internal memory provided in the mobile phone, and is a mobile phone for address book data, mail data, image files, music files as playable music data, various setting data, and the like. Stores various data to be used. The data storage unit 212 is also used as data storage means for storing sound data such as sound and sound effects of a predetermined length that are output when the mobile phone 20 is shaken. The lengths of output sounds such as these sounds and sound effects are set to a length that can be recognized by the user. For example, the length is set within a range of 100 milliseconds to 10 seconds. These sounds having a predetermined length are output individually or in combination. The data storage unit 212 may be configured by a memory card or the like as an external storage medium that can be attached to and detached from the mobile phone body.

  The wireless communication unit 213 performs voice communication and mail communication with another mobile phone via the mobile phone communication network 10 as a communication network, and performs data communication with a server on the communication network. Therefore, wireless communication is performed with the base station of the mobile phone communication network 10.

The operation unit 214 includes a data input key (ten key, * key, # key) 21, a call start key 22a, an end key 22b, a scroll key 24, multifunction keys 23a, 23b, 25, a microphone 26, and the like. Yes. The operation unit 214 is also used as an operation mode selection unit that allows the user to select one of a plurality of operation modes with different combinations of sounds to be output. In this case, when the operation unit 214 is operated and one of the operation modes is selected, the main control unit 211 employs a combination of sounds set in advance to the selected operation mode. Then, control is performed so that a predetermined combination of sounds corresponding to the operation mode is output when the mobile phone 20 is shaken.
In addition to the operation unit 214, the input unit of the cellular phone 20 includes a microphone 26 as a sound signal input unit.

  The display unit 215 includes a liquid crystal display (LCD) 27, a drawing data processing unit, and the like, and can display various images. The display unit 215 can display a standby screen, a menu screen, a mail screen, a WEB browsing screen, various setting screens, and the like.

The detection unit 216 is used as detection means for detecting the posture and acceleration generated in the mobile phone 20. The detection unit 216 includes, for example, a biaxial acceleration sensor, a sensor drive circuit, a detection signal processing circuit (filter circuit, A / D converter), and the like. The acceleration sensor detects accelerations α _X and α _Y directed in two directions (X-axis direction and Y-axis direction in FIG. 1) orthogonal to each other in a plane parallel to the operation surface provided with the key 21 and the like. . The acceleration sensor is mounted on a circuit board (not shown) provided inside the mobile phone 20. As the acceleration sensor, a known sensor that can detect the accelerations α _X and α _Y can be used. Further, instead of the two-axis acceleration sensor, a three-axis sensor that detects accelerations α _X , α _Y , and α _Z in three directions orthogonal to each other (X-axis direction, Y-axis direction, and Z-axis direction in FIG. 1). An acceleration sensor may be used.

  The detection unit 216 is configured to detect acceleration (dynamic acceleration that changes in a relatively short cycle) generated when the user shakes the mobile phone 20, and gravity acceleration (relative to the mobile phone 20 when the mobile phone 20 falls freely due to gravity). Static acceleration that changes over a long period) can be detected.

Here, the output of the detection unit 216 can arbitrarily set an offset. In the present embodiment, a signal corresponding to gravitational acceleration 1 g [m / sec ² ] is output when the mobile phone 20 is stationary, and 0 [m / sec ² ] when the mobile phone 20 is free-falling. Is set to output a signal corresponding to. This output offset outputs a value corresponding to 0 [m / sec ² ] when the mobile phone 20 is stationary, and is 1 g [m / sec ² ] when the mobile phone 20 is free-falling. You may set so that a corresponding signal may be output.

  The two types of acceleration (static acceleration and dynamic acceleration) can be separated by a filter having a predetermined cutoff frequency characteristic. For example, the static acceleration (gravity acceleration) can be separated by passing the output signal of the acceleration sensor through a low-pass filter. On the other hand, the dynamic acceleration (acceleration when an impact is applied) can be separated by passing the output signal of the acceleration sensor through a high-pass filter or a high-frequency band-pass filter. This dynamic acceleration (acceleration when an impact is applied) may be detected without passing the output of the acceleration sensor through the filter.

  If the alarm action can be set to generate vibration (vibration), the change in acceleration due to the vibration caused by the alarm action and when the user gives an impact to the mobile phone to stop the alarm. An acceleration threshold and a frequency band (filter characteristic) for detecting an alarm stop operation are appropriately set so that the change from the acceleration can be distinguished.

  The acceleration data detected by the detection unit 216 at a predetermined sampling interval is transferred to the main control unit 211 as digital data.

The detection unit 216 may be configured to use a geomagnetic sensor in addition to the acceleration sensor. This geomagnetic sensor is a three-axis sensor that detects a magnetic field strength component or magnetic flux density component of geomagnetism on a three-dimensional coordinate composed of the X axis, the Y axis, and a Z axis orthogonal to these axes. Using the detection result of the geomagnetic sensor, the angles θX, θY, and θZ around the X axis, the Y axis, and the Z axis are detected. Specifically, using the angles θX, θY, and θZ around the X, Y, and Z axes, the amount of change when the direction of the geomagnetism changes with respect to the reference geomagnetic direction (reference direction). To detect. Thereby, when the cellular phone 20 changes its attitude from the attitude when the direction of geomagnetism is in the reference direction, the attitude after the change can be specified by the angles θX, θY, and θZ. Hereinafter, the angle around the X axis θX is referred to as “pitch angle”, the angle θY around the Y axis as “roll angle”, and the angle θZ around the Z axis as “yaw angle”.
The pitch angle θX, roll angle θY, and yaw angle θZ may be calculated using only the detection data of the geomagnetic sensor, or calculated using both the detection data of the geomagnetic sensor and the detection data of the acceleration sensor. Also good.

  The sound output unit 217 includes a speaker 28 and the like, and is used as a means for outputting sound during a voice call. In addition, the sound output unit 217 outputs sound, sound effects, music, and the like based on data stored in the data storage unit 212. It is also used as sound output means. This sound output unit 217 uses a speaker 28 as a receiver speaker (receiver) for listening to voice during a call, and separately from the speaker 28 for voice call, an external output speaker that outputs the alarm sound and music. You may comprise so that it may provide.

  In addition, as an output means, you may provide the light emission part which emits light using light emitting elements, such as LED (light emitting diode). The light emitting unit may be configured to switch and output a plurality of colors of light.

  The sound, the sound effect, the sound such as music, and the light are controlled by the main control unit 211 with respect to the sound output unit 217 and the light emitting unit 211. For example, the user holds the mobile phone 20 in a predetermined direction with a predetermined intensity. It can be output at the timing of shaking.

  The clock unit 218 measures the current date and time, and passes the generated time data to the main control unit 211.

  FIG. 3 is a graph showing an example of an output change of the detection unit 216 when the mobile phone 20 is shaken. FIG. 4 is a flowchart showing an example of control when the mobile phone 20 is shaken to output sound. In FIG. 3, the thick line indicates the output of the acceleration αX in the X direction of FIG. 1, and the thin line indicates the output of the acceleration αY in the Y direction of FIG. For each acceleration αX, αY, a positive threshold A and a negative threshold B are provided.

  First, prior to sound output using the mobile phone 20, the user operates the mobile phone 20 to set the type of sound output when the mobile phone is shaken on a predetermined sound output setting screen. Keep it. This setting may be performed by selecting one of a plurality of types of operation modes registered in advance according to different themes and characters. In each operation mode, a combination of output sounds is set according to the theme, character, or the like corresponding to the operation mode. In addition to the types of output sound, the length of the period during which the acceleration of the mobile phone 20 is detected in the output period of each sound (hereinafter referred to as “detection period”), the interval between adjacent sound output periods, that is, the sound output pause A period (hereinafter referred to as “sound output interval”) may also be set. With this setting, the user can operate the mobile phone 20 after grasping at which timing the mobile phone 20 should be shaken or at what interval each sound is output. Further, the setting status regarding the length of the detection period may be displayed on the display unit 215 of the mobile phone 20 in the form of a countdown timer. In this case, the user can visually grasp how many seconds are left until the acceleration detection starts and how many seconds the detection period continues.

  Table 1 shows the contents of two types of patterns A and B set as sounds to be output in this control example. The reproduction time (output period) of the pattern A sound is 1.2 seconds, and the acceleration detection period A for determining whether to output the subsequent pattern B sound is 0.6 seconds. This detection period A is set in the latter half of the sound output period of pattern A. The interval from the end of the pattern A sound output period to the start of the subsequent pattern B sound output is set to 0 seconds. The sound file of the pattern A is stored in the memory with a file name “Sound_A.smf”. On the other hand, the reproduction time (output period) of the sound of the pattern B is 1.0 second, and the detection period B for detecting the acceleration for determining whether the sound of the subsequent pattern B is output is 0.3 second. . The detection period B is set in the latter half of the sound output period of the pattern B, as in the case of the detection time A. The interval from the end of the pattern B sound output period to the start of the subsequent pattern B sound output is set to 0 seconds. The sound file of pattern B is stored in the memory with the file name “Sound_B.smf”. Note that the sound data file is not limited to the smf file in this example, and may be a file of another data format as long as it can be called and output by the mobile phone.

  In the control example of FIG. 4, after performing the above setting, the user operates the mobile phone 20 to start monitoring the swing operation of the mobile phone 20 by detecting acceleration (S <b> 101). Then, after the state where the magnitude of the acceleration detected by the detection unit 216 is below the preset threshold values A and B continues, the main control unit 211 increases the threshold values A and B or more as indicated by the reference symbol P1 in FIG. When it is detected (S102), control is performed to start sound output of pattern A (S103).

  Next, the main control unit 211 determines whether or not the magnitude of the acceleration detected by the detection unit 216 is greater than or equal to the thresholds A and B within the detection period A set in the second half of the pattern A sound output period. Is determined (S104). Here, when the acceleration exceeding the thresholds A and B is not detected within the detection period A (No in S104), the sound output of the pattern A is terminated without performing the sound output of the subsequent pattern B (S105). . On the other hand, when the acceleration exceeding the thresholds A and B is detected within the detection period A (Yes in S104), the sound output of the pattern A is finished (S106) and the sound output of the pattern B is started (S107). .

  Next, the control unit 211 sets whether or not the magnitude of acceleration detected by the detection unit 216 is greater than or equal to the thresholds A and B within the detection period B set in the latter half of the output period of the sound of the pattern B. Is determined (S108). Here, when the accelerations exceeding the thresholds A and B are detected within the detection period B (Yes in S108), the sound output of the pattern B is once ended (S109) and the sound output of the same pattern B is continuously started. (S107). When the swinging operation of the mobile phone 20 is repeated in this manner, the sound output of the pattern B can be repeated a plurality of times after the sound output of the pattern A (S107 to S109). For example, when the sound of the pattern A is the voice “A” and the sound of the pattern B is the voice “TA”, by continuously shaking the mobile phone 20, “WATTA ...” continuously. Sound can be output. With such sound output control, for example, when the mobile phone 20 is shaken according to a song during karaoke, an effective rhythm sound or a matching hand sound can be inserted according to the song.

  On the other hand, if the accelerations exceeding the thresholds A and B are not detected within the detection period B (No in S108), the sound output of the pattern B is temporarily terminated without performing the sound output of the subsequent pattern B (S110). ).

  Next, the main control unit 211 determines whether or not to end the monitoring of the swing operation of the mobile phone 20 for sound output (S111). Here, when the main operation unit 211 determines that the end of the swing operation monitoring is instructed by the key operation of the operation unit 214 (Yes in S111), the main operation unit 211 ends the monitoring of the swing operation of the mobile phone 20 by detecting the acceleration. . On the other hand, when determining that the end of the swing operation monitoring has not been instructed (No in S111), the main control unit 111 controls to continue monitoring the swing operation of the mobile phone 20 by detecting the acceleration.

  As described above, according to the present embodiment, when the user shakes the mobile phone 20 in the hand during the sound output period of the preceding pattern A, the sound of the preceding pattern A is output following the sound output of the preceding pattern A. Since the sound is output, a plurality of sounds A and B can be output continuously without a break. Furthermore, when the user shakes the mobile phone 20 while holding it in the pattern B sound output period, the sound of the same pattern B is output continuously after the sound output of the pattern B. The sound of the pattern B can be continuously output without a break.

Note that the sound output control is not limited to the control described in FIGS. 3, 4, and Table 1, and is subsequent to the preceding sound output based on the acceleration detection result of the mobile phone 20. Any control can be made as long as it is controlled to output the above sound.
For example, the length of the detection time Ts for detecting the acceleration of the mobile phone 20 and the detection interval Tp that is the interval (cycle) between the acceleration detection start timings are set in advance, and based on the setting, as shown in FIG. You may control to output a several separate sound continuously. In the example of FIG. 5, the sound output start timing coincides with the acceleration detection start timing, and the sound output continues until the next acceleration detection is started, that is, until the next sound output is started. In the setting in this control example, for example, the detection time for detecting the former acceleration can be set to 5 seconds, 10 seconds, etc., and the detection interval for the latter acceleration can be set to every 5 seconds, every 10 seconds, etc. can do. Then, by combining the former detection time Ts and the latter detection interval Tp, for example, acceleration detection (sound output) starts every 10 seconds, and the acceleration detection is performed for 5 seconds. With this setting, the user can operate the mobile phone 20 after grasping at which timing or how many seconds the mobile phone 20 should be shaken. Furthermore, the setting status regarding the length of the detection time Ts and the detection interval Tp may be displayed on the display unit 215 of the mobile phone in the form of a countdown timer. In this case, the user can visually grasp in seconds how many seconds until the detection starts and how many seconds until the detection time continues.

  Further, the present invention can be applied to other portable electronic devices such as a mobile phone, a phone such as a PHS and a car phone, and a portable PDA, and similar effects can be obtained.
