The music playback unit 12 includes a playback processing unit 19 that performs decoding and playback processing of music data as content data, and a speaker 20 that outputs the played back sound, and plays back and outputs music content. Here, the music playback unit 12 realizes the function of the output unit. Further, the backlight 18 of the display unit 11 can realize the function of the light emitting unit, and the display unit 11 can realize the function of the output unit together with the music reproducing unit 12.

The gas component sensor 13 realizes the function of the gas component detector and detects the substance component of the surrounding gas. The determination unit 14 determines whether the gas component detected by the gas component sensor 13 is harmful or harmless, and changes in the concentration of the gas component. The storage unit 15 stores and registers music information related to music set for each gas component type and concentration change, light emission information related to a light emission mode such as a light pattern, and the like. Settings and registration of music information, light emission information, and the like in the storage unit 15 are set in advance in the device or set by a user operation instruction, and the setting information is registered. The control unit 16 controls each part of the device, and performs various signal processing, music reproduction control, backlight lighting control, and the like. In the first embodiment, it is assumed that the control unit 16 performs music reproduction for warning according to a change in concentration when a harmful gas component is detected. Here, the storage unit 15 includes a memory for storing information. The control unit 16 and the determination unit 14 are configured by a memory for storing processing information, a processor that performs a processing operation, and the like, and each function is realized by executing a predetermined program.

FIG. 2 is a flowchart showing the operation of the portable electronic device according to the first embodiment. Here, an operation in the case of reproducing a warning sound according to a change in concentration when a harmful component of gas is detected will be described. The processing procedure in FIG. 2 mainly shows the operation of the control unit 16.

First, the control unit 16 starts the detection operation of the gas component sensor 13 (step S11). Then, the determination unit 14 captures the detection value from the gas component sensor 13, and the control unit 16 determines the determination result in the determination unit 14. Here, it is determined whether or not the gas component detected by the determination unit 14 is determined to be a harmful component, and it is further determined whether or not the concentration change is an increase determination (step S12). As the determination of harmful components, based on the gas component information registered in the storage unit 15, it is determined whether the detected component has an unpleasant odor or is a gas harmful to the human body such as gas. In Step S12, when the determination unit 14 determines the harmful component and the increase determination of the concentration change, the control unit 16 sets the volume to be larger than the predetermined volume, and the music reproducing unit 12 performs the detection of the harmful component. Predetermined music set for warning or music currently being played is output and played at a volume higher than normal. Further, a predetermined light pattern set for warning when detecting harmful components is emitted by the backlight 18 of the display unit 11, and a predetermined warning is displayed by the display 17. Thus, an alarm warning is given to the user by sound, light, and display (step S13).

Next, the control unit 16 determines whether the concentration determination by the determination unit 14 is an increase determination or a decrease determination (step S14). In step S14, when the concentration determination is an increase determination, the control unit 16 determines that the risk level of harmful components has continued or increased, and continues alarm warning or starts alarm warning again. Here, as in step S13, the music playback unit 12 reproduces predetermined music at a high volume, and the display unit 11 emits a predetermined light pattern and displays a screen (step S15). Thereafter, the process returns to step S14 and the same process is performed.

FIG. 3 is a block diagram showing a configuration of a main part of a portable electronic device according to the second embodiment of the present invention. The present embodiment can be applied to a portable music player or the like as a portable electronic device having a function of reproducing content such as music.

The portable electronic device of the second embodiment is obtained by partially changing the functions of the determination unit 24, the storage unit 25, and the control unit 26 as compared with the first embodiment described above. Constituent elements similar to those of the first embodiment are denoted by the same reference numerals and description thereof is omitted.

The determination unit 24 determines whether the gas component detected by the gas component sensor 13 is harmful or harmless, the type of fragrance, and the concentration change of the gas component. The memory | storage part 25 memorize | stores and registers the music information regarding the music play list set for every kind of fragrance and density | concentration change, the light emission information regarding light emission aspects, such as a light pattern. Settings and registration of music information, light emission information, and the like in the storage unit 25 are set in advance in the device or set by a user operation instruction, and the setting information is registered. The control unit 26 controls each part of the device, and performs various signal processing, music reproduction control, backlight lighting control, and the like. In 2nd Embodiment, the control part 26 shall perform music reproduction etc. according to the kind of fragrance and density | concentration change, when a gas component is harmless.

FIG. 4 is a flowchart showing the operation of the portable electronic device according to the second embodiment. Here, the operation | movement in the case of reproducing | regenerating a music playlist according to the kind of gas scent and a density | concentration change is shown. In the processing procedure of FIG. 4, the operation of the control unit 26 is mainly illustrated.

First, the control unit 26 starts the detection operation of the gas component sensor 13 (step S21). Then, the determination unit 24 captures the detection value from the gas component sensor 13, and the control unit 26 determines the determination result in the determination unit 24. Here, it is determined whether the gas component detected by the determination unit 24 is determined to be a harmless component, and it is further determined whether the concentration change is an increase determination (step S22). As the determination of the harmless component, based on the gas component information registered in the storage unit 25, it is determined whether there is a matching harmless fragrant gas component. In step S22, when the determination unit 24 determines the harmless component and the increase in the concentration change, the control unit 26 gradually increases the volume from the low volume state, and gradually increases the volume by the music playback unit 12. The predetermined music set for reproduction at the time of detecting the increase in density corresponding to the scent is reproduced while increasing the volume. At this time, the music to be played back may be set in units of one song, or may be set in units of playlists including a plurality of songs. In addition, the backlight 18 of the display unit 11 emits a predetermined light pattern corresponding to the scent and set for reproduction when detecting an increase in density. Thus, music playback and light emission set for each detected scent component are performed, and music and light are linked to the surrounding environment (step S23).

Next, the control unit 26 determines the density change determination by the determination unit 24, and determines whether the density change is an increase determination, a decrease determination, or a detection level or less (step S24). In step S24, when the concentration change is an increase determination, the control unit 26 determines that the detected scent concentration is increasing, and the music playback unit 12 performs predetermined playback for playback when the concentration increase is detected. Then, a predetermined light pattern is emitted by the display unit 11, and music reproduction and light emission corresponding to the detected scent and density increase are performed (step S25). Thereafter, the process returns to step S24 to perform the same process.

In step S24, if the concentration change is a decrease determination, the control unit 26 determines that the detected scent concentration is decreasing, and the music playback unit 12 is used for playback when the concentration decrease is detected. The predetermined music is reproduced by the above, and a predetermined light pattern is emitted by the display unit 11 to reproduce and emit the music corresponding to the detected scent and concentration reduction (step S26). Thereafter, the process returns to step S24 to perform the same process.

If it is determined in step S24 that the density is equal to or lower than the detection level, the control unit 26 gradually decreases the volume from a predetermined volume, and the music playback unit 12 plays the music while gradually decreasing the volume. And the light emission by the display unit 11 is stopped (step S27). Thereby, the music and light corresponding to the scent detected with a natural feeling for the user are stopped.

By the above operation, a gas component of a registered scent such as a scent preferred by the user can be detected, and when the concentration is increased, predetermined music reproduction and light emission set for each scent can be performed. For example, it is possible to switch between a plurality of music and light patterns registered by the scent component, such as playing music of different songs and genres for each detected scent type. In addition, when the concentration of the gas component of the corresponding scent decreases and falls below the detection level, music playback and light emission can be automatically stopped. Note that when it is determined that the density has decreased, it is also possible to play music of different songs and genres at the time of density increase determination and at the time of density decrease determination without stopping the music playback. It is also possible to perform volume control such as gradually increasing the volume when determining density increase and gradually decreasing the volume when determining density decrease.

(Third embodiment)
FIG. 5 is a block diagram showing a configuration of a main part of a portable electronic device according to the third embodiment of the present invention. The present embodiment can be applied to a portable music player or the like as a portable electronic device having a function of reproducing content such as music.

The portable electronic device of the third embodiment is obtained by partially changing the functions of the determination unit 34, the storage unit 35, and the control unit 36 as compared to the second embodiment described above. Constituent elements similar to those in the first and second embodiments are denoted by the same reference numerals and description thereof is omitted.

The determination unit 34 determines whether the gas component detected by the gas component sensor 13 is harmful or harmless, the type of fragrance, and the concentration level of the gas component. The storage unit 35 stores and registers music information related to a music playlist set for each scent type and density level (density range), light emission information related to a light emission mode such as a light pattern, and the like. The setting registration of music information, light emission information, etc. in the storage unit 35 is set in advance in the device, or is set by a user operation instruction, and the setting information is registered. The control unit 36 controls each part of the device, and performs various signal processing, music reproduction control, backlight lighting control, and the like. In 3rd Embodiment, the control part 36 shall perform music reproduction etc. according to the kind and density | concentration level of fragrance, when a gas component is harmless.

FIG. 6 is a flowchart showing the operation of the portable electronic device according to the third embodiment. Here, an operation in the case of reproducing a music playlist according to the type of gas scent and the concentration level is shown. In the processing procedure of FIG. 6, the operation of the control unit 36 is mainly shown.

First, the control unit 36 starts the detection operation of the gas component sensor 13 (step S31). Then, the determination unit 34 captures the detection value from the gas component sensor 13, and the control unit 36 determines the determination result in the determination unit 34. Here, it is determined whether or not the gas component detected by the determination unit 34 is determined to be a harmless component, and it is further determined whether or not the concentration level is in zone 1 representing a predetermined concentration range (step S32). In step S32, when the determination unit 34 determines the harmless component and the density level zone 1 determination, the control unit 36 gradually increases the sound volume from the low sound volume state so that the music playback unit 12 gradually increases the sound volume. The predetermined music set for reproduction when the density zone 1 is detected is reproduced corresponding to the scent while the volume is increased. At this time, the music to be played back may be set in units of one song, or may be set in units of playlists including a plurality of songs. Further, the backlight 18 of the display unit 11 emits a predetermined light pattern corresponding to the scent and set for reproduction when the density zone 1 is detected. Thus, music reproduction and light emission set for each detected scent component and concentration range are performed, and music and light are linked to the surrounding environment (step S33).

Next, the control unit 36 determines the density level determination by the determination unit 34 and determines whether the density level is the determination of the zone 1 or the determination of the zone 2 that represents a density range different from the zone 1 (for example, the zone It is determined whether 1 <zone 2) or below the detection level (step S34). In step S34, when the density level is zone 1 determination, the control unit 36 determines that the detected scent density level is zone 1, and plays music for playback when the density level zone 1 is detected. The unit 12 reproduces predetermined music, and the display unit 11 emits a predetermined light pattern to reproduce and emit music corresponding to the detected scent and concentration zone 1 (step S35). Thereafter, the process returns to step S34 and the same process is performed.

In step S34, if the concentration level is zone 2 determination, the control unit 36 determines that the detected scent concentration level is zone 2, and for reproduction when the concentration level zone 2 is detected. The music reproduction unit 12 reproduces predetermined music, the display unit 11 emits a predetermined light pattern, and music reproduction and light emission corresponding to the detected scent and density zone 2 are performed (step S36). Thereafter, the process returns to step S34 and the same process is performed.

If it is determined in step S34 that the density is equal to or lower than the detection level, the control unit 36 gradually decreases the volume from a predetermined volume, and the music playback unit 12 plays the music while gradually decreasing the volume. And the light emission by the display unit 11 is stopped (step S37). This stops the music and light corresponding to the scent and concentration level detected with a natural feeling for the user.

By the above operation, a gas component of a registered scent such as a scent preferred by the user can be detected, and predetermined music reproduction and light emission set for each scent and concentration level can be performed. For example, it is possible to switch a plurality of music and light patterns registered depending on the scent component and concentration level, such as playing music of different tunes and genres for each detected scent concentration level. In addition, when the concentration of the gas component of the corresponding scent falls below the detection level, music playback and light emission can be automatically stopped. When the density is below the detection level, it is possible to play music of a different tune or genre from that at other density levels without stopping the music playback. Also, volume control such as gradually increasing the volume or gradually decreasing the volume depending on the density level is possible.
