For example, when the source device 10 is in the power OFF state, the power ON control may not be performed even when the separation distance Lh ≦ the predetermined distance LX is detected. The standby mode is a state in which a part of the distance measuring unit 31, the RFID reading unit 33, and the control unit 41 is activated, and the normal mode is a state in which another configuration is activated. is there.

  The receiving unit 330 receives content information and setting information from the source device 10. Of the content information, the content itself is received in accordance with a transmission command from the home audio 30, and the setting information and the accompanying information of the content are received at the probability of communication with the source device 10. However, for accompanying information, only data necessary for creating a playlist, such as a title name, is received at the time of communication probability, and data with a relatively large capacity, such as a content image, is displayed at the It may be configured to receive at any time according to a transmission command from the audio 30. The content playback unit 340 plays back the received content (outputs sound).

  The determination unit 350 determines whether or not the headphones 20 (second playback device) can perform wireless communication when the power supply control unit 320 is turned on. Since the determination is performed by communication by the wireless communication units 26 and 38, it is determined that wireless communication is impossible when the headphones 20 are not within the wireless communication range or when the headphones 20 are in the power OFF state. When the determination unit 350 determines that “wireless communication is possible”, the level adjustment unit 360 adjusts the output level of the own device according to the separation distance Lh between the own device and the source device 10. Specifically, the volume adjustment is performed so that the volume gradually increases as the separation distance Lh decreases. As shown in FIG. 11, the level adjustment unit 360 is configured until the source device 10 approaches within a predetermined distance LY (where LY <LX) (when the predetermined distance LX ≦ the separation distance Lh <the predetermined distance LY). The volume is set to 0 (zero). Thereafter, volume adjustment is performed until the source device 10 approaches within a predetermined distance LZ (where LZ <LY) (when the predetermined distance LY ≦ the separation distance Lh <the predetermined distance LZ).

  When the determination unit 350 determines that “wireless communication is possible”, the level adjustment command unit 370 commands the headphone 20 to perform level adjustment according to the separation distance Lh between the own device and the source device 10. Specifically, the sound volume adjustment command is issued so that the sound volume gradually decreases as the separation distance Lh decreases. Note that the volume adjustment command to the headphones 20 is also performed within the range of predetermined distance LY ≦ separation distance Lh <predetermined distance LZ, similarly to the volume adjustment of the own device. The power OFF command unit 380 issues a power OFF command to the headphones 20 when the distance between the own device and the source device approaches the predetermined distance LZ (see FIG. 11).

  The setting change unit 390 changes settings related to content reproduction (level adjustment for each frequency band such as a high band, a middle band, and a low band) in a state where wireless communication with the source device 10 is possible. The setting change is performed using a menu screen displayed on the touch panel TP or an attached operation unit (remote controller). In addition, the setting change is reflected in reproduction in real time. The setting information rewriting unit 410 rewrites the setting information in the setting information storage unit 120 of the source device 10 in accordance with the change of the setting change unit 390. In addition, when the setting is changed, an option for whether or not to rewrite the setting information storage unit 120 is displayed, and only when “Rewrite” is selected, the setting information storage unit 120 may be rewritten. good.

  When the charge control unit 420 detects that the source device 10 has approached the predetermined distance L0 (however, 0 ≦ L0 <LX) based on the measurement result of the distance measurement unit 310, the charge control unit 420 contacts the source device 10 in a non-contact manner. Charge the battery. In the present embodiment, charging is started when the predetermined distance L0≈0 and the source device 10 is arranged on the touch panel TP (see FIG. 11). The charging control unit 420 can simultaneously charge N (where N ≧ 2 is an integer) source devices 10, and there are M (where M> N is an integer) source devices 10. If it exists within the predetermined distance L0, the charging priority is determined according to the distance from each source device 10 measured by the distance measuring unit 310. For example, when the home audio 30 has two power supply coil arrays and the two source devices 10 are arranged on the touch panel TP, the two are charged simultaneously. However, when three or more source devices 10 are arranged on the touch panel TP, the reference position of the home audio 30 (for example, the center position of the touch panel TP) and the reference position of each source device 10 (for example, the source device 10). 2 units with a short distance to the center of gravity position) are charged first, and then the remaining unit is charged. Note that the reference position of the source device 10 may be determined based on the detection result of the touch panel TP (arrangement region determination result of the source device 10), or may be determined based on the reading result of the RFID 17.

  On the other hand, the headphone 20 includes a reception unit 210, a content reproduction unit 220, a level adjustment unit 230, and a power supply control unit 240 as main functional configurations. Among them, the receiving unit 210 has the wireless communication unit 26 as a main part, and the content reproduction unit 220 has the DSP 23, the amplifier 24, and the speaker 25 as main parts. Further, the level adjustment unit 230 and the power supply control unit 240 have the control unit 21 as a main part.

  The reception unit 210 and the content reproduction unit 220 function in the same manner as the reception unit 330 and the content reproduction unit 340 of the home audio 30. The level adjustment unit 230 adjusts the level of the own device (headphone 20) in accordance with a command from the home audio 30 (level adjustment command unit 370). Specifically, a volume designation value corresponding to the separation distance Lh between the home audio 30 and the source device 10 is transmitted from the home audio 30, and the volume is adjusted so as to be the volume designation value. In addition, the power supply control unit 240 turns off the power of its own device in accordance with a command from the home audio 30 (power-off command unit 380). The level adjustment unit 230 and the power supply control unit 240 operate in response to a similar command from the car audio 40. That is, volume adjustment / power control as shown in FIG. 11 is executed in the process in which the user carrying the source device 10 and the headphones 20 gets into the car and approaches the car audio 40. However, the predetermined distances LX, LY, LZ, and L0 in the home audio 30 and the predetermined distances LX, LY, LZ, and L0 in the car audio 40 are set to independent values.

  Next, the flow of volume adjustment / power control according to the first embodiment will be described with reference to the flowchart of FIG. The home audio 30 (car audio 40) measures the separation distance Lh from the source device 10 (S11), and determines whether or not the source device 10 has approached the predetermined distance LX (S12). If it is determined that the source device 10 has approached the predetermined distance LX (S12: Yes), it is determined whether or not the main power supply of the device itself is in a power OFF state (S13). (S13: Yes), the main power supply of the device is turned on (S14).

  Subsequently, it is determined whether or not the headphones 20 are present in the wireless communicable range (S15). If they are not present (S15: No), the process is terminated. If it exists (S15: Yes), the distance Lh from the source device 10 is measured (S16), and it is determined whether or not the source device 10 has approached the predetermined distance LY (S17). When it is determined that the source device 10 has approached the predetermined distance LY (S17: Yes), the volume of the own device is adjusted according to the predetermined distance LY (S18), and the volume to the headphones 20 according to the predetermined distance LY. An adjustment command is issued (S19). The headphones 20 adjust the volume of the own device according to the volume adjustment command (S20).

  Thereafter, it is further determined whether or not the source device 10 has approached the predetermined distance LZ (S21). If it is determined that the vehicle has approached the predetermined distance LZ (S21: Yes), a power OFF command is sent to the headphones 20 (S22). The headphone 20 turns off the power of its own device in accordance with the power-off command (S23).

  As described above, according to the present embodiment, the home audio 30 adjusts the volume of the content being played back according to the separation distance Lh from the source device 10, so that the user who carries the source device 10 has the home audio 30. It is possible to prevent the volume from suddenly increasing when approaching. In addition, in a situation where there is a headphone 20 as well as the source device 10 and the home audio 30, the volume of the headphone 20 gradually decreases as the user approaches the home audio 30, and conversely, the volume of the home audio 30 increases. Seamless music playback can be realized. That is, by adjusting the volume of the two playback devices, it is possible to eliminate a sense of incongruity when automatically switching the playback device as the audio output destination.

  Further, since the home audio 30 is automatically turned on when the source device 10 approaches a certain distance, it is possible to save the user from having to operate the power supply and to realize more seamless music playback. In addition, by providing a distance (predetermined distance LX−predetermined distance LY) until the volume adjustment starts (starts increase) after the power is turned on, the volume of the home audio 30 can be suddenly increased even if time is required for initialization after the main power is turned on Can be solved. Further, when the separation distance Lh between the home audio 30 and the source device 10 approaches LZ, the headphone 20 is turned off, so that the headphone 20 is turned off when the headphone 20 becomes unnecessary after returning home. This saves you time and effort.

  The home audio 30 can rewrite the setting information and reflect the rewriting result on the source device 10. Thereby, the setting information reflecting the user's preference can be stored and carried in the source device 10, and the user's preference can be reflected in any playback device. Of course, the headphones 20 can also read the setting information stored in the source device 10 and reproduce the content according to the setting information.

  Further, since the home audio 30 can be charged simultaneously with respect to a plurality of source devices 10, when there are two or more source devices 10, the charging time can be shortened. Furthermore, when the source devices 10 that exceed the number that can be charged simultaneously are placed on the touch panel TP, the charging priority is determined according to the separation distance Lh from each source device 10, so charging is performed first. The charging order can be changed according to the user's intention, such as placing the source device 10 to be performed near the reference position of the home audio 30.

  Note that the following configuration can be considered as a modification of the volume adjustment / power control. When the wireless communication with the headphone 20 is possible, the level adjustment command unit 370 according to the modified example outputs an output level to the headphone 20 when the separation distance Lh between the own device and the source device 10 approaches the predetermined distance LY. The level adjustment is commanded so as to gradually decrease. In addition, the power-off command unit 380 according to the modification commands the power-off after the level adjustment according to the command from the level adjustment command unit 370. On the other hand, when wireless communication with the headphones 20 is possible, the level adjustment unit 360 according to the modification gradually increases the output level of the own device when the separation distance Lh between the own device and the source device 10 approaches the predetermined distance LY. Make it bigger. Here, the flow of the modification will be described with reference to the flowchart of FIG.

  The home audio 30 (car audio 40) measures the separation distance Lh from the source device 10 (S31), and determines whether or not the source device 10 has approached the predetermined distance LX (S32). If it is determined that the source device 10 has approached the predetermined distance LX (S32: Yes), it is determined whether or not the main power source of the device itself is in a power OFF state (S33). (S33: Yes), the main power supply of the device is turned on (S34).

  Subsequently, it is determined whether or not the headphone 20 is present in the wireless communicable range (S35). If the headphone 20 is present (S35: Yes), the separation distance Lh from the source device 10 is measured (S36), and the source device is determined. It is determined whether or not 10 has approached the predetermined distance LY (S37). When it is determined that the source device 10 has approached the predetermined distance LY (S37: Yes), the volume of the own device is gradually increased (S38). That is, the level is raised from the volume value A to the volume value B over a predetermined time. On the other hand, a volume adjustment command and a power-off command are given to the headphones 20 (S39). The headphone 20 gradually decreases the volume of its own device in accordance with the volume adjustment command and the power OFF command, and then turns off the power (S40). That is, the level is lowered over a predetermined time from the sound volume designated value A designated by the home audio 30 to the sound volume designated value B (for example, volume 0), and then the power is turned off. As described above, according to the modification, seamless music reproduction can be realized with simpler control in a situation where there are two reproduction devices.

  In addition, the following modifications can be employed. For example, in the above embodiment, when the power supply control unit 320 detects that the source device 10 has approached the predetermined distance LX, it turns on the main power of its own device. When it is detected that the user has moved away from the LX, a control for turning off the main power supply of the own device may be performed. According to this configuration, it is possible to save the trouble of turning off the power of the home audio 30 when the user goes out.

  In the above embodiment, the charging control unit 420 sets the predetermined distance L0≈0 and starts charging when the source device 10 is placed on the touch panel TP. However, the charging control unit 420 sets the predetermined distance L0 ≠ 0, It is good also as a structure which charges even if the apparatus 10 is not arrange | positioned on the touchscreen TP. Similarly to the volume adjustment / power control, the charging priority may be determined according to the separation distance Lh through the space with each source device 10.

  In the above embodiment, the music data is exemplified as the content. However, the present embodiment may be applied to digital data such as video data, image data, text data, and a mixture thereof. For example, level adjustment control such as gradually increasing the brightness (and volume) of the TV when returning home while watching a video (or image or text) with a smartphone and approaching the TV at home can be considered.

  In the above embodiment, the volume of the home audio 30 is not adjusted when the headphones 20 do not exist in the wireless communicable range (S15: No in FIG. 12). It is good also as a structure which performs 30 volume adjustments. That is, the volume of the home audio 30 may be gradually increased as the source device 10 approaches the home audio 30. In addition, when the headphones 20 are not in the wireless communicable range, the user may be able to set whether or not to adjust the volume of the home audio 30.

  In the above embodiment, the distance measuring unit 310 measures the separation distance Lh between the own device (home audio 30) and the source device 10 based on the reading result of the RFID reading unit 33. The separation distance Lh may be measured based on the communication result. In addition, a combination of a plurality of measuring units such as the RFID reading unit 33 and the wireless communication unit 38 may be configured to perform more accurate distance measurement.

  In the above-described embodiment, the receiving unit 330 receives content information and setting information from the source device 10, but may receive only setting information in response to a command from the home audio 30 (playback device side). good. For example, when the home audio 30 reproduces content provided from another source other than the source device 10, the content can be reproduced according to the setting information received from the source device 10.

  In the above embodiment, the source device 10 is configured to store content therein, but simply provides content acquired from the outside (such as a Web server) to the home audio 30 or the headphones 20. Also good.

[Second Embodiment]
Next, a second embodiment (user interface) of the present invention will be described with reference to FIGS. In the present embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. Moreover, the modification applied about the component similar to 1st Embodiment is applied similarly about this embodiment.

  FIG. 14 is a functional block diagram of the reproduction system SY according to the second embodiment. The source device 10 includes a content storage unit 110 and a transmission unit 130 as main functional configurations. On the other hand, the home audio 30 includes a receiving unit 330, a content reproduction unit 340, an arrangement region determination unit 430, a reproduction operation region display unit 440, an operation element display unit 450, a reproduction information display unit 460, and a content image display as main functional configurations. Unit 470 and charging control unit 480. Since the content storage unit 110, the transmission unit 130, the reception unit 330, and the content reproduction unit 340 function in the same manner as in the first embodiment, description thereof is omitted. In addition, the arrangement area determination unit 430, the reproduction operation area display unit 440, the operation element display unit 450, the reproduction information display unit 460, and the content image display unit 470 have the control unit 31 as a main part, and the charging control unit 480 includes a charging unit. 39 is the main part.

  The arrangement area determination unit 430 determines an arrangement area (a ground area to the touch panel TP) of the source device 10 on the touch panel TP. The reproduction operation area display unit 440 displays a circular area of a predetermined size including at least a part of the arrangement area of each source device 10 and the center position P1 of the touch panel TP as a reproduction operation area EP corresponding to each source device 10. . In the present embodiment, a circle having a predetermined radius is set so that the center position P2 of the reproduction operation area EP is set on a straight line connecting the reference position P3 (center of gravity) of each source device 10 and the center position P1 of the touch panel TP. The playback operation area EP is displayed.

  FIG. 15 is a diagram illustrating an arrangement example of the reproduction operation area EP on the touch panel TP. FIG. 6A shows an example of the arrangement of the reproduction operation areas EP when two source devices 10 are arranged side by side. In the figure, a symbol T0 indicates a straight line connecting the reference position P3 (not shown) of each source device 10 and the center position P1 of the touch panel TP. Thus, the arrangement of the reproduction operation area EP is determined according to the reference position P3 of the source device 10. Note that the arrangement of the reproduction operation area EP does not change depending on the orientation of the source device 10 (see FIG. 16). FIG. 15B shows an arrangement example of the reproduction operation area EP when two source devices 10 are arranged vertically. In this case, a part of the reproduction operation area EP (dotted line portion in the figure) is not displayed because it is outside the touch panel TP. FIG. 15C shows an arrangement example of the reproduction operation area EP when the two source devices 10 are arranged obliquely.

  As shown in FIG. 15, when the center position P2 of the two reproduction operation areas EP is located on both sides of the center position P1 and on the straight line T0, the overlapping areas EPW all have the same area regardless of the arrangement. Become. When the reference position P3 of the two source devices 10 is arranged on one side of the center position P1 and on the straight line T0, the two reproduction operation areas EP completely overlap, but in this case, a predetermined amount Only two positions (for example, a rotation angle of 30 degrees with respect to the center position P1) are displayed, and the two reproduction operation areas EP are displayed. Needless to say, even when the two reproduction operation areas EP do not completely overlap, the two reproduction operation areas EP may be displaced by a predetermined amount when they are almost overlapped.

  Further, when a plurality of source devices 10 are arranged on the touch panel TP, the playback operation region display unit 440 displays the playback operation regions EP corresponding to the source devices 10 in different colors. In the present embodiment, the reproduction operation area EP of the source device 10 first arranged on the touch panel TP is displayed in red, the reproduction operation area EP of the source device 10 arranged next is blue, and so on according to the arrangement order. Determine the color. It should be noted that the illumination unit 63 (see FIG. 2) of each source device 10 is set to the same color as the display color of the corresponding playback operation area EP (lights up, flashes, or rotates and flashes). Thereby, the user can grasp at a glance which source device 10 corresponds to which reproduction operation area EP.

  On the touch panel TP, the operator display unit 450 is an operator group G2 for performing the playback operation of the source device 10 in the playback operation area EP of the source device 10 and the remaining area excluding the arrangement area of the source device 10. Is displayed. The operation element display unit 450 displays the operation element group G2 in the same color as the corresponding reproduction operation area EP (reproduction operation area EP surrounding the operation element group G2). Note that the operators included in the operator group G2 indicate reproduction, pause, fast forward / rewind, and the like (see FIGS. 16 and 17). In addition, an operator for specifying a reproduction type (normal reproduction, repeat reproduction, random reproduction, etc.), volume adjustment, title / chapter / track search, and the like may be included in the operator group G2. However, in this embodiment, only a volume adjustment operator (volume operator G3) performs a special display. Specifically, as shown in FIG. 17, a straight line from the circumference of the reproduction operation area EP toward the center position P2 and character information indicating the volume value are set to a position (center position corresponding to the set volume value). (An angle centered on P2). Therefore, the volume adjustment is performed by dragging the straight line of the volume operator G3 as shown by the arrow in the drawing.

  The reproduction information display unit 460 displays the reproduction information G1 related to the content being reproduced in the remaining operation area within the reproduction operation area EP of the source device 10 and excluding the arrangement area of the source device 10. The reproduction information G1 is also displayed in the same color as the corresponding reproduction operation area EP, as with the operator group G2. Here, the reproduction information G1 indicates accompanying information such as artist name and title name, and analysis information such as BPM, KEY, and genre (see FIGS. 16 and 17). In the present embodiment, the analysis information is stored in the source device 10 as information analyzed in advance by an unillustrated device (such as a PC), but the music data is analyzed by the home audio 30 and the analysis result is reproduced. It may be displayed as information G1.

  By the way, the operation element display unit 450 and the reproduction information display unit 460 are part of the reproduction operation area EP that does not overlap regardless of the orientation of the source device 10 (hereinafter referred to as “information display area ES”). The control group G2 and the reproduction information G1 are displayed in the display. FIG. 16 shows an information display area ES set in the playback operation area EP on the left side of FIG. In this way, two rectangular areas uniquely determined according to the center position P2 of the reproduction operation area EP and the center position P1 of the touch panel TP (a rectangle whose upper side and lower side are parallel to the straight line T0 and whose left side and right side have a predetermined length). Is set as the information display area ES.

  FIG. 17 shows a display example of the operator group G2 and the reproduction information G1 on the information display area ES set as shown in FIG. FIG. 18 shows a display example of the information display area ES set in the left reproduction operation area EP of FIG. 15C, the operator group G2, and the reproduction information G1. As shown in the figure, the character arrangement of the information displayed in the information display area ES (or the array of operation elements) is the user side (home audio) regardless of the direction of the information display area ES (the inclination of the straight line T0). It is set to be parallel when viewed from the front side of 30). In addition, the line feed or the information is reduced as appropriate depending on the amount of information of the reproduction information G1 and the space of the information display area ES (when the display space cannot be secured, BPM is not displayed, etc.). Further, the operator display unit 450 and the reproduction information display unit 460 display only when the corresponding source device 10 is reproducing. Thereby, the user can grasp at a glance which source device 10 is being reproduced.

  The content image display unit 470 displays the content image G4 related to the content being played back at the center (in the playback operation area EP) of the touch panel TP (see FIG. 7A). Further, the content image G4 of the content to be reproduced next is displayed on the back of the content image G4 related to the content being reproduced. The content image G4 is received by the receiving unit 330 at least before the content (music data) is reproduced. For content not accompanied by a content image, a specific image (such as a logo indicating a manufacturer name) prepared in advance or not displayed is displayed. When a plurality of source devices 10 are arranged on the touch panel TP, the content image G4 is displayed in the overlapping area EPW of the plurality of reproduction operation areas EP corresponding to each source device 10.

  When the charge control unit 480 detects that the source device 10 is disposed on the touch panel TP, the charge control unit 480 performs non-contact charging on the source device 10. In addition, N (where N ≧ 2 integer) source devices 10 can be charged simultaneously, and M (where M> N integer) source devices are arranged on the touch panel TP. In this case, the source device 10 being played is preferentially charged. For example, when the home audio 30 has two power supply coil arrays and the two source devices 10 are arranged on the touch panel TP, the two are charged simultaneously. However, when three or more source devices 10 are arranged on the touch panel TP, the source device 10 (one or two) transmitting content is charged first, and the remaining source devices after the completion of charging. 10 is charged. In addition, when the source device 10 is arrange | positioned more than the number which can be charged simultaneously, charge priority is determined according to the distance with each source device 10 measured by the distance measurement part 310 (1st Embodiment). (Charging control of the second embodiment) or whether to give priority to the source device 10 being played back (charging control of the second embodiment) may be arbitrarily set by the user.

  As described above, according to the second embodiment, the operator group G2 for performing the reproduction operation of the source device 10 is an area (information display area ES) that avoids the arrangement area of the source device 10 on the touch panel TP. Therefore, the visibility of the operator group G2 can be reliably ensured regardless of the arrangement of the source device 10. Further, since the reproduction operation area EP centering on the arrangement of the source device 10 is displayed and the operation element group G2 is displayed in the reproduction operation area EP area, which operation element group G2 corresponds to which source apparatus 10. Can be clearly shown. Further, since the playback operation area EP is also displayed for the non-playing source device 10, the user can confirm that the source device 10 is recognized by the home audio 30. In addition, since the reproduction operation area EP is displayed at an appropriate position according to the reference position P3 of the source device 10, even when a plurality of source devices 10 are arranged, the plurality of reproduction operation areas EP are arranged with good appearance. it can.

  Further, not only the operator group G2 but also the reproduction information G1 related to the content being reproduced is displayed in the reproduction operation area EP, so that the user can grasp the information related to the content. Further, when a plurality of source devices 10 are arranged on the touch panel TP, each reproduction operation area EP is displayed in a different color, so that even when two or more source devices 10 are arranged nearby, each reproduction operation area EP is displayed. The user can easily identify the EP. Further, since the content image G4 is displayed in the overlapping area EPW (the center part of the touch panel TP) of each reproduction operation area EP, the user can intuitively grasp the content being reproduced.

  In addition, since the source device 10 is arranged on the touch panel TP for performing the content reproduction operation and the content is reproduced, it is not necessary to insert the source device 10 into the dock as in the conventional case, and the accessory is attached to the accessory tray. The source device 10 can be used on the touch panel TP as if it were placed.

  The home audio 30 can simultaneously charge a plurality of source devices 10, and if the source devices 10 exceeding the number that can be simultaneously charged are arranged on the touch panel TP, the content being played back Since the source device 10 providing the priority is given priority, charging can be performed efficiently.

  In the above embodiment, the source device is arranged on the touch panel TP of the home audio 30 (horizontal plane parallel to the placement surface of the home audio 30). However, the source device 10 is arranged on a touch panel having a non-horizontal surface. May be. Hereinafter, an embodiment (modification) in which the source device 10 is mounted on the front surface of the car audio 40 will be described.

  FIG. 19 is a front view of a car audio 40 according to a modification. The entire front surface of the car audio 40 according to this modification is configured with a touch panel 96. Further, the touch panel 96 is formed with a plurality of protrusions 51 (three attachment parts in the figure), and the through openings 71 of the source device 10 are inserted and attached to these protrusions 51. Each protrusion 51 incorporates a contact sensor (not shown). With these configurations, the arrangement region determination unit 430 according to this modification determines the arrangement region of the source device 10 according to which protrusion 51 among the plurality of protrusions 51 the source device 10 is made.

  For example, FIG. 19A shows a display example when the source device 10 is attached to the left protrusion 51 of the three protrusions 51. A playback operation area EP is displayed around the source device 10. An operator group G2 is also displayed at a predetermined position (remaining area excluding the arrangement area of the source device 10) in the reproduction operation area EP. On the other hand, the reproduction information G1 is displayed on the touch panel 14 of the source device 10. Further, the character direction of the reproduction information G1 is set to the illustrated direction (vertical direction) based on the detection result of the gyro sensor incorporated in the source device 10. On the other hand, FIG. 19B shows a display example when the source device 10 is attached to the central protrusion 51 among the three protrusions 51. As described above, the display positions of the reproduction operation area EP and the operator group G2 are determined with the protrusion 51 to which the source device 10 is attached as the center. Although FIG. 19 illustrates the case where one source device 10 is mounted, two or three source devices 10 may be mounted simultaneously. In this case, the playback operation area EP is displayed for each source device 10, but the operator group G2 displays only those corresponding to the source device 10 being played back. In the modification, a plurality of power supply coil arrays are incorporated on the back side of the touch panel 96 in accordance with the positions of the respective protrusions 51, so that the plurality of source devices 10 can be charged simultaneously. Yes.

  As described above, according to the modification shown in FIG. 19, even when the surface of the touch panel 96 is not a horizontal plane, the source device 10 can be fixedly arranged. In addition, by providing the protrusion 51 in advance, the arrangement region can be determined even when the source device 10 is not completely in contact with the touch panel 96 surface. Instead of the protrusion 51, a plurality of docks for fitting the source device 10 are provided on the touch panel 96, and the arrangement area of the source device 10 is determined according to which dock the source device 10 is mounted. May be. Further, a plurality of locking portions for locking the source device 10 may be provided instead of the protrusion 51.

  In addition, the following modifications can be employed. For example, in the above embodiment, the position of the center of gravity of the source device 10 is used as the reference position, but other positions (for example, the center of the touch panel 14 and the center of the ring operation unit 12) may be used as the reference position. In addition, playback information G1, an operator group G2, a volume controller G3, a content image G4, and the like are displayed in the playback operation area EP with the reference position of the source device 10 as a reference. Some or all of the information may be displayed. That is, it is preferable to display these pieces of information at least in the remaining area excluding the arrangement area of the source device 10.

  In the above embodiment, the size of the reproduction operation area EP is set to a predetermined size (same size), but may be varied depending on the arrangement of the source device 10. For example, when the reproduction operation area EP is displayed as shown in FIG. 15B, a part of the reproduction operation area EP is missing. May be reduced. Further, it is possible to eliminate the lack of the circular area by making the overlapping area EPW wider instead of reducing the size of the reproduction operation area EP.

  In the above embodiment, the display color of the playback operation area EP is determined according to the arrangement order of the source devices 10. However, the user's favorite color is set in advance in each source device 10, The display color of each corresponding reproduction operation area EP may be determined according to the setting. Also, the display color may be determined according to analysis information (BPM, KEY, genre, etc.) of the content being reproduced or the content to be reproduced next.

  Further, in the above embodiment and the modification, the case where the user interface for performing the reproduction operation of the source device 10 is displayed on the touch panel TP, 96 of the reproduction device is illustrated, but other electronic devices and display devices are used.

[Third Embodiment]
Next, a third embodiment (shuffle reproduction) of the present invention will be described with reference to FIGS. In the present embodiment, the same components as those in the above-described embodiments are denoted by the same reference numerals, and detailed description thereof is omitted. Moreover, the modification applied about the component similar to said each embodiment is applied similarly about this embodiment.

  FIG. 20 is a functional block diagram of the reproduction system SY according to the third embodiment. The source device 10 includes a content storage unit 110 and a transmission unit 130 as main functional configurations. On the other hand, the home audio 30 includes a distance measurement unit 510, a transmission command unit 520, a reception unit 330, a content reproduction unit 340, and a content image display unit 530 as main functional configurations. Since the content storage unit 110, the transmission unit 130, the reception unit 330, and the content reproduction unit 340 function in the same manner as in the first embodiment, description thereof is omitted. The distance measuring unit 510 has the RFID reading unit 33 as a main part, and the transmission command unit 520 and the content image display unit 530 have the control unit 31 as a main part.

  The distance measuring unit 510 measures the separation distance between the own device (home audio 30) and each source device 10. In the present embodiment, the “separation distance” refers to the distance from the center position P1 of the touch panel TP to the reference position P3 of each source device 10. For example, as shown in FIG. 21B, when <source device 1> and <source device 2> are arranged, the separation distance from <source device 1> is L1, and the separation distance from <source device 2>. The distance is L2.

  The transmission command unit 520 issues a content transmission command to each source device 10 based on the measurement result of the distance measurement unit 510. Specifically, the ratio of the number of contents in shuffle playback is determined according to the ratio of the separation distance from each source device 10, and a transmission command is randomly issued to each source device 10 according to the ratio. FIG. 21A is a playback ratio table showing the relationship between the ratio of the separation distance from each source device 10 and the ratio of the number of playback songs during shuffle playback. The reproduction ratio table is stored in the control unit 31 (ROM) of the home audio 30. For example, when the ratio L1 / L2 of the separation distance is less than 1/5, that is, when the separation distance from <source device 2> is greater than five times the separation distance from <source device 1>, <source device The ratio of the number of playback songs of 1> and <source device 2> is 5: 1. In this case, for example, after a transmission command for 5 songs is given to <source device 1>, a transmission command for 1 song is sent to <source device 2> until a playback end instruction is issued. Alternatively, during playback of a certain predetermined number (for example, 12 songs), the number of playback songs of <source device 1> and <source device 2> is randomly selected so as to be a number corresponding to the ratio (for example, 10 songs and 2 songs). A regeneration command is issued. As described above, the transmission command unit 520 issues a content transmission command to each source device 10 so that the number of contents provided from the source device 10 having a short separation distance is larger than that of the source device 10 having a long separation distance. .

  Note that the home audio 30 obtains a content list stored in each source device 10 at the time of communication probability with each source device 10, and plays a shuffle play playlist (listing the content playback order). Create. Then, the distance measurement unit 510 measures the distance from each source device 10 as needed, and updates the playlist when the ratio of the distance from each source device 10 changes. The transmission command unit 520 designates the content to be reproduced next in accordance with the created playlist and issues a transmission command. In addition, the user selects whether to perform normal playback (a method of playing back stored content in order for only one source device 10) or shuffle playback, and select to perform shuffle playback. Only when this is done, the shuffle reproduction based on the measurement result of the distance measurement unit 510 may be performed.

  The content playback unit 340 performs shuffle playback of the received content in response to the content transmission command from the transmission command unit 520. Note that cross-fade processing is performed when content is switched. In the crossfade process, volume adjustments such as fade-in and fade-out may be instructed to each source device 10, or the volume output on the home audio 30 side may be adjusted. Further, at the time of the cross fade process, a synchronization process for synchronizing the BPM of the content before and after switching may be performed.

  The content image display unit 530 displays a content image G4 related to the content being reproduced on the touch panel TP. The display position is the same as in the second embodiment (see FIG. 7A). Also, the content image display unit 530 covers the second content image G42 related to the content to be reproduced next to the first content image G41 related to the content being reproduced at the time of the crossfading process by the content reproduction unit 340. In this way, the display is switched.

  FIG. 22 is an explanatory diagram showing the display switching. As shown in the figure, in a state where the first content is being played back, a part of the second content image G42 is displayed on the back surface of the first content image G41 (see FIG. 22A). In this state, the image size of the second content image G42 is smaller than the image size of the first content image G41. When the crossfading process is started, the transmittance of the first content image G41 is increased, and the image size of the second content image G42 is increased (see FIG. 22B). Further, as the crossfading process proceeds, the transmittance of the first content image G41 further increases, and the image size of the second content image G42 further increases (see FIG. 22C). After that, at the end of the cross-fade process (at the start of reproduction of the second content), the first content image G41 disappears, and the image size of the second content image G42 becomes the maximum value. The content image G43 of the third content to be reproduced is displayed on the back of the second content image G42 (see FIG. 22D).

  As described above, according to the third embodiment, since the content ratio of shuffle playback is varied according to the ratio of the separation distance between the home audio 30 and each source device 10, novel playback control (freshness) is performed. realizable. Further, since the transmission command is issued so that the number of contents provided from the source device 10 having a short separation distance is larger than that of the source device 10 having a long separation distance, the number of contents to be reproduced can be changed by changing the arrangement of the source devices 10. Can be arbitrarily changed.

  Further, at the time of content switching for shuffle playback, the first content image G41 related to the content being played back is switched so as to cover the second content image G42 related to the content to be played next. In contrast, content switching (cross-fade processing) can be transmitted intuitively and easily.

  In addition, the following modifications can be employed. For example, in the above embodiment, the distance from the center position P1 of the touch panel TP to the reference position P3 of each source device 10 is measured, but as shown in FIG. 23, the housing (RFID reader 33) of the home audio 30 is measured. ) And the housing (RFID 17) of each source device 10 may be measured. In this case, when a plurality of source devices 10 are arranged on the touch panel TP, measurement is performed with a separation distance 0 (as the same separation distance). The modification can be applied not only to the home audio 30 but also to the car audio 40 and the headphones 20.

  In the above embodiment, shuffle playback by two source devices 10 is illustrated, but the present invention can also be applied to shuffle playback by three or more source devices 10.

  Further, in the above embodiment, the ratio of the number of contents when performing shuffle playback is varied according to the distance from each source device 10, but the present invention is also applicable to playback methods other than shuffle playback. For example, in a state where communication with two source devices 10 is possible, a playback method in which a transmission command is given only to the source device 10 with a smaller separation distance, or transmission to the source device 10 with a smaller separation distance A playback method may be considered in which when a command is issued and all stored content has been played, a transmission command is sent to the source device 10 with the larger separation distance.

  In the above embodiment, a playlist is created in advance on the home audio 30 side, and the content to be reproduced next is designated according to the playlist. However, creation of the playlist may be omitted. In this case, only the transmission command is issued from the home audio 30, and the content to be transmitted is determined on the source device 10 side.

  Although three embodiments and modifications have been described above, the embodiments and modifications may be combined. In each of the above embodiments, the audio device such as the home audio 30 is exemplified as the playback device. However, the present invention can also be applied to other audio devices such as a DJ device and a broadcasting device. This embodiment can be applied not only to audio equipment but also to playback equipment capable of wireless communication with the source equipment 10. For example, if the source device 10 can transfer video content and various files (text file, image file, etc.), a display device (TV, projector, etc.) can be applied as a playback device. Furthermore, the present invention can also be applied to computers and smartphones, such as when performing music playback / video playback using an application installed on a computer or smartphone.

  Moreover, it is possible to provide each part and each function of the reproduction | regeneration system SY shown to said each embodiment as a program. Further, the program can be provided by being stored in various recording media (CD-ROM, flash memory, etc.). That is, a program for causing a computer to function as each unit of the reproduction system SY and a recording medium on which the program is recorded are also included in the scope of the right of the present invention. In addition, the system configuration of the reproduction system SY, the device configuration of each audio device, the processing steps, and the like can be appropriately changed without departing from the gist of the present invention, regardless of the above embodiment.
