Description

  The present invention relates to an audio system music selection device used when selecting and specifying a music to be reproduced and output, and an item selection device used when selecting a selection item button displayed on a screen.

  2. Description of the Related Art Conventionally, vehicles are equipped with various in-vehicle systems such as an audio system that reproduces music in the vehicle and a car navigation system that guides a driver to a travel destination. Among these, the audio system is an acoustic in-vehicle system that reproduces music by reproducing and outputting music data stored in a storage medium (for example, a Compact Disc), and sends a radio broadcast in the vehicle. Also, in recent audio systems, for example, there are models that can reproduce more music in the car by storing not only map data but also music data of music in HDD (Hard Disk Drive) for car navigation systems. It has become widespread.

This type of audio system is provided with a user interface (operation panel) that is used when switching between starting and stopping of the system or selecting and specifying the music to be played back. As a user interface of an audio system that stores music data in the HDD, for example, an in-vehicle display that is used as a display system shared among various in-vehicle systems displays a song name that is currently selected, and this is displayed on the display. One that designates a piece of music to be reproduced and output by selecting and specifying it using an operation system is widely used. A specific example of the interface of the audio system is disclosed in Patent Documents 1 and 2, for example.

  By the way, the user interface of the audio system described in the background art operates a feed switch and a return switch arranged as an operation system of the display, and displays a piece of music on the display one by one. A selection method for selecting and specifying is common. That is, in this type of user interface, the display switching direction according to the switch operation at the time of selecting a music piece, that is, the switching direction of the designated music piece is only uniaxial (for example, the horizontal direction of the screen). Many.

  For this reason, for example, when it is desired to specify the playback music to be returned, an operation process of returning the music one by one is required, so that the music cannot be specified efficiently. Therefore, in this type of user interface, since it takes time to re-specify the music, there is a problem that the music selection performance of the music is low. In particular, when this type of audio system is mounted on a vehicle, if it takes time to select such a piece of music, this may cause a problem in driving, so some countermeasure has been demanded.

  SUMMARY OF THE INVENTION An object of the present invention is to provide an audio system music selection device and item selection device that can improve music selection performance of reproduced music.

  According to the present invention, it is possible to improve the music selection performance at the time of performing a selection operation of a reproduction music piece in the audio system.

Hereinafter, an embodiment of a music piece selection device and an item selection device of an audio system embodying the present invention will be described with reference to FIGS.
As shown in FIG. 1, a vehicle 1 is equipped with an audio system 2 that performs music reproduction output and radio broadcasting in the vehicle. The audio system 2 is an HDD type that stores music data Dms in a vehicle-mounted HDD (Hard Disk Drive) 3 and plays music in the vehicle by playing back the music data Dms. The audio system 2 is a CD (Compact Disc) or the like. It is also possible to read the music data Dms of the storage medium and reproduce and output it. The HDD 3 is not limited to the one dedicated to the audio system 2, and may be shared with, for example, a car navigation system that guides the driver to the current position and the route to the destination by voice or a map.

  The center cluster 4 in the vehicle is provided with a user interface (UI) 5 as an operation panel of the audio system 2. The user interface 5 is provided with a display 6 as a display system of the audio system 2. The display 6 is made of color liquid crystal, for example, and is disposed at a substantially central position of the center cluster 4. In addition to being used as a display system for the audio system 2, the display 6 is also used as a display system for the above-described car navigation system and an air conditioner system for adjusting the air conditioning in the vehicle. The display 6 corresponds to display means.

  The user interface 5 is provided with an operation switch 7 as an input system of the audio system 2 as shown in FIG. A switch knob 9, which is an operation part of the operation switch 7, is attached to the panel portion 8 of the user interface 5 so as to be movable relative to the panel portion 8. The switch knob 9 has a cylindrical shape and is externally fitted to a columnar switch support portion 10 disposed on the panel portion 8. The switch knob 9 can be rotated around the axis of the switch support 10 (in the direction of arrow A in FIG. 2), and can be pushed and pulled along the axial direction of the switch support 10 (in the direction of arrow B in FIG. 2). In addition, when the switch knob 9 is released after the switch knob 9 is operated, the switch knob 9 automatically returns to the initial position before the operation is started. The operation switch 7 corresponds to an operation unit and a multidirectional operation type operation unit.

  That is, as shown in FIG. 3 and FIG. 4, the operation amount of the switch knob 9 in the left-right direction (Lls on the left side and Lrs on the right side) and the operation amount in the push / pull direction of the switch knob 9 (push-side) Is set to a predetermined amount in advance and when the switch knob 9 is operated to the vicinity of the maximum operation position in each operation direction, the switch contact in the operation direction at that time (not shown) While the is in the on state, further knob operations are restricted. When the switch knob 9 is released in this state, the switch knob 9 automatically returns to the initial position before the operation is started, and the switch contact that has been in the ON state returns to the OFF state.

  As shown in FIG. 5, the music selection screen 11 is displayed on the display 6 as the menu screen of the audio system 2. On the music selection screen 11, a button group 13 including a plurality of music selection buttons 12, 12... Is displayed as a music selection when the audio system 2 plays music. By operating the operation switch 7, these buttons 12 are displayed. , 12... Is selected, the song is reproduced and output. These song selection buttons 12, 12,... Are a certain type of icon having a design corresponding to each song (including the CD album unit), and are displayed by the amount stored in the HDD 3, for example. The music selection buttons 12, 12,... Are arranged in a state that matches the operation allowable direction of the operation switch 7, that is, the rotation operation direction and the push / pull operation direction. The program selection button 12 corresponds to a selection item button.

  In this example, when the thickness direction of the screen of the display 6 is a reference axis (functional axis) K, the display 6 is arranged along the circumference of the screen along the reference axis K and along the axis of the reference axis K. Are also arranged in the screen thickness direction. These music selection buttons 12, 12,... Are arranged in a grid pattern in the screen circumferential direction and the screen thickness direction of the switch knob 9. These music selection buttons 12, 12,... Are arranged separately for each genre in the screen circumferential direction, and are divided for each tempo in the screen thickness direction. As the genre of the song, for example, there are rock, hip hop, reggae, classic and the like. Further, when the song selection buttons 12, 12... Are arranged at a tempo in the screen thickness direction, for example, a fast tempo song is placed on the front side of the display 6 and a slow tempo song is placed on the back side of the display 6. Has been placed. The screen circumferential direction corresponds to the screen direction, and the screen thickness direction corresponds to the screen depth direction. The genre corresponds to the first attribute, and the tempo corresponds to the second attribute.

  Here, for example, when the switch knob 9 is rotated in the left-right direction, the button group 13 displayed on the display 6 rotates along the rotation operation direction of the switch knob 9 at that time, that is, the screen circumferential direction. When the switch knob 9 is pushed and pulled in the front-rear direction, the button group 13 of the display 6 moves along the push-pull operation direction of the switch knob 9 at that time, that is, the screen thickness direction. Then, by repeating the rotation operation and push-pull operation of the operation switch 7 several times, the music selection button 12 to be reproduced and output is aligned with the designation frame 14 displayed at the lower left side of the display 6. , Select the song. In this example, the third button from the front side of the screen is extracted as a selected state from among the plurality of song selection buttons 12, 12... And is enlarged and displayed in the designation frame 14. The designation frame 14 corresponds to the rated position.

  As shown in FIG. 2, the operation switch 7 is embedded with a vibrator 15 capable of generating vibrations at a predetermined cycle (predetermined rhythm). The vibrator 15 is a device that generates vibration (vibration) at a predetermined rhythm by causing the diaphragm to vibrate with a small motor, for example, and is disposed in contact with the switch knob 9 inside the casing. Yes. This vibrator 15 transmits the vibration of itself to the operation switch 7 (switch knob 9) and vibrates the operation switch 7 (switch knob 9), thereby gripping and operating the operation switch 7 (switch knob 9). It transmits a rhythmic vibration with a certain regularity.

  In addition, the panel unit 8 is provided with an infrared sensor 16 that detects whether a human body (operator's hand) is approaching in the vicinity of the operation switch 7. The infrared sensor 16 is a sensor that detects whether or not the operator intends to operate the operation switch 7 by checking whether or not a human body has entered the detection area of the infrared sensor 16. When the infrared sensor 16 is not detecting a human body, that is, when the operator is not touching the operation switch 7, the vibrator 15 is in a non-vibrating stop state, and when the infrared sensor 16 detects a human body, that is, an operation is not performed. When the person touches the operation switch 7, the activated state is generated in which vibration is generated.

  As shown in FIG. 6, the user interface 5 is provided with an interface control ECU 17 as a control unit that performs overall control of the user interface 5. The interface control ECU 17 includes a CPU 18, a ROM 19, a RAM 20, and the like, for example. The interface control ECU 17 is connected to the HDD 3, the operation switch 7, the display 6, the vibrator 15, and the infrared sensor 16 via electric wiring (not shown), and an audio mechanism that is a main system of the audio system 2. 21 is also connected via electrical wiring (not shown). The interface control ECU 17 constitutes display control means, selection state switching means, and vibrator control means.

  The ROM 19 stores a control program 22 that is executed when the user interface 5 selects and designates the music selection buttons 12, 12,. The control program 22 performs graphic display on the display 6 based on the music data Dms stored in the HDD 3, and switches the display display based on the operation of the operation switch 7, while selecting which music selection buttons 12, 12,. Is a program for driving the vibrator 15 based on the determination result. The CPU 18 performs determination of the selection state of the music selection buttons 12, 12... And drive control of the vibrator 15 using the RAM 20 as a work area based on the control program 22 of the ROM 19.

Next, the operation of the user interface 5 of this example will be described.
When the interface control ECU 17 recognizes that the power supply of the audio system 2 has been turned on, the interface control ECU 17 switches the audio system 2 that has been in a stopped state to the activated state. At this time, if the operation mode of the audio system 2 is the music playback mode, the interface control ECU 17 takes in the music data Dms (music playback data) of the song that is currently selected from the HDD 3 and outputs it to the audio mechanism 21. As a result, the selected song is reproduced and output in the vehicle. The music reproduction data is a data group corresponding to the actual music piece in the music piece.

  In addition, when the audio system 2 is in the activated state, the interface control ECU 17 determines the music outline information (for example, artist name, music title, CD jacket) included in each music data Dms from each music data Dms stored in the HDD 3. Cover design, genre, tempo, etc.). This music outline information is, for example, a command-like data group written in the vicinity of the head of each music data Dms, and music reproduction data is written after the music data Dms. The interface control ECU 17 is a button group 13 in which a plurality of song selection buttons 12, 12... Are arranged in a substantially cylindrical shape according to genre and tempo on the screen of the display 6 based on the song outline information acquired from the HDD 3. 5) is displayed on the screen.

  When the playback system is switched when the audio system 2 is activated, the switch knob 9 of the operation switch 7 is operated. At this time, for example, when the switch knob 9 is operated to rotate counterclockwise, the interface control ECU 17 rotates the display of the button group 13 on the screen to the left in the screen circumferential direction as shown in FIG. At this time, for example, when the switch knob 9 is rotated once in the left direction, the button group 13 on the screen is rotated by one turn, that is, with respect to the music selection button 12 which has been positioned in the designated frame 14 until then. The display is switched so that the left adjacent item is positioned in the designated frame 14. Further, at this time, for example, when the left rotation operation of the switch knob 9 is pressed for a long time, the button group 13 on the screen continuously rotates to the left side and rotates at the position when the switch knob 9 is turned off. Stop. Note that when the switch knob 9 is operated to rotate right, the left and right are reversed as compared with the left rotation operation, but the same screen switching is performed.

  When the switch knob 9 is pulled out to the near side, the interface control ECU 17 moves the display of the button group 13 on the screen to the near side in the screen thickness direction as shown in FIG. At this time, for example, when the switch knob 9 is pulled out once to the front side, the button group 13 on the screen is moved by one stroke, that is, with respect to the music selection button 12 that has been positioned in the designated frame 14 until then. The display is switched so that the one in the back is positioned in the designated frame 14. Further, at this time, for example, when the pulling operation of the switch knob 9 is long pressed, the button group 13 on the screen continuously moves to the near side, and moves to the near side when the switch knob 9 is turned off. Stops. Note that when the switch knob 9 is pushed into the back side, the screen is switched in the same manner, although the front and back are reversed from those during the pull-out operation.

  The interface control ECU 17 switches the music data Dms (music) for the music of the music selection buttons 12, 12,... Newly located in the specification frame 14 when the music selection buttons 12, 12,. Reproduction data) is read from the HDD 3 and output to the audio mechanism 21. When the audio mechanism 21 receives new music data Dms (music playback data), the audio mechanism 21 discards the music data Dms (music playback data) that has been output until then, and newly receives music data Dms (music playback data). Is stored and reproduced and output in the car.

  Further, when the audio system 2 is activated, the infrared sensor 16 is also activated, and monitors whether the operator's hand approaches the operation switch 7 from that time. When the interface control ECU 17 receives an ON signal from the infrared sensor 16, the interface control ECU 17 recognizes that the operator has touched the operation switch 7 and switches the vibrator 15 to the drive state. At this time, the interface control ECU 17 vibrates the vibrator 15 in accordance with the tempo of the song that is in the selected state at that time, that is, the song that is in the designated state as the reproduction target. The interface control ECU 17 refers to the tempo in the music outline information included in the music data Dms, and drives and controls the vibrator 15 based on the tempo in the music outline information. The vibrator 15 vibrates fast when the tempo of the song in the selected state is fast, and vibrates slowly when the tempo of the song in the selected state is slow. With such a vibration state, the vibrator 15 notifies the operator who is grasping and operating the switch knob 9 of the tempo of the music piece currently selected.

  In this example, the operation switch 7 can be operated in the two-axis directions of the rotation direction and the push-pull direction, and the music piece selection buttons 12, 12... Displayed on the display 6 are displayed on the display 6. By arranging according to the direction, that is, the rotation direction and the push-pull direction, the music selection can be performed in the biaxial operation direction. As a result, when selecting a music piece, the desired music piece is efficiently reached, so that the music selection performance of the music piece can be improved. In particular, when this type of user interface 5 is mounted on the vehicle 1, if the music selection performance can be improved in this way, this music selection work will hardly interfere with driving, and this is also highly effective. It can be said.

  Further, the vibrator 15 is incorporated in the operation switch 7 (switch knob 9) which is the operation system of the audio system 2, and the vibrator 15 is vibrated in accordance with the tempo of the music piece in the selected state. Thereby, it becomes possible to notify the operator of the tempo of the music piece in the selected state at that time depending on the vibration state of the vibrator 15 at that time. Therefore, not only from the screen of the display 6 but also from the hand holding the operation switch 7 (switch knob 9), it becomes possible for the operator to know the tempo of the selected song, so that the music selection performance is further improved. It becomes possible. In addition, since it is possible to select music without looking at the screen of the display 6, it is highly effective in ensuring safety when driving the vehicle. Furthermore, even if the audio system 2 is in the mute state, the music can be selected.

According to the configuration of the present embodiment, the following effects can be obtained.
(1) While the operation switch 7 can be operated in the biaxial direction of the rotation direction and the push-pull direction, the music selection buttons 12, 12,... On the display 6 are operated in the biaxial direction permitted by the operation switch 7. By arranging the screens according to the above, it is possible to select music pieces in two-axis operation directions. As a result, when selecting the music piece, the desired music piece selection buttons 12, 12,... Can be efficiently traced, so that the music selection performance of the music piece can be improved.

  (2) The operation switch 7 is a switch type that can be operated in the biaxial direction of the rotation direction and the push-pull direction. By the way, in this kind of switch, when the knob takes a rotating operation type, it takes an operating form in which the knob is rotated on the spot. For example, a sliding operation type in which the knob is slid in the panel direction (left-right direction). Compared with, the switch size can be reduced by the amount that does not require the knob operation space. Therefore, if the operation switch 7 that can operate the switch knob 9 in the rotational direction and the push-pull direction as in this example is employed, this type of switch component can be made small.

  (3) The vibrator 15 is incorporated into the operation switch 7, and the vibrator 15 is vibrated in accordance with the tempo of the music currently selected. Therefore, not only on the screen of the display 6, but also with the hand (finger) touching the switch knob 9 when operating the operation switch 7, the operator has changed from the vibration state of the vibrator 15 at that time to the selected state. The song (tempo) can be grasped. Therefore, music selection can be performed both in the screen display state of the display 6 and in the vibration state transmitted from the vibrator 15 to the hand, so that the music selection performance can be further improved.

  (4) The music selection buttons 12, 12,... (Button group 13) displayed on the screen of the display 6 are arranged according to the genre of the music in the screen circumferential direction, and are arranged according to the tempo of the music in the screen thickness direction. Is done. As a result, the music selection buttons 12, 12... Displayed on the screen of the display 6 are arranged side by side on the screen with regularity, so that the rough arrangement positions of the music selection buttons 12, 12. Can grab. Therefore, since the selection time can be shortened when selecting the music selection buttons 12, 12,..., The music selection performance can be further improved.

  (5) A designation frame 14 is provided at a position diagonally lower left of the screen of the display 6, and the music selection buttons 12, 12... On the display 6 are moved by operating the operation switch 7 to select the music selection button 12 of the music to be reproduced and output. Is placed in the designation frame 14 to select the music. For this reason, the music selection button 12 in the selected state is displayed on the screen in the large size display area called the designation frame 14 in the large size. Therefore, the song selection button 12 in the selected state at that time can be displayed on the screen in a state that is easier for the operator to understand.

  (6) An infrared sensor 16 is provided in the vicinity of the operation switch 7, and when the infrared sensor 16 detects the approach of the operator's hand to the operation switch 7, the vibration that has been in a stopped state until then is waited for. The vibration of the child 15 is started. Therefore, when the operator does not operate the operation switch 7, the vibrator 15 is stopped, so that power saving of the power source (vehicle battery) of the vibrator 15 can be achieved.

Note that the embodiment is not limited to the configuration described so far, and may be modified as follows.
The button display selection method of the user interface 5 is not necessarily limited to a method of selecting a predetermined one from the plurality of selection buttons 12, 12... Arranged three-dimensionally in the screen circumferential direction and the screen depth direction. For example, as shown in FIG. 9, a group of buttons arranged in the circumferential direction of the screen is grouped into one type of selection item, and this grouping is arranged in the thickness direction of the screen, and one selection button 12 is selected for each unit of the grouping. The method to be issued may be used.

  As this example, the button display selection method of the user interface 5 of this example is used as an operation panel of an air conditioner system. In this case, as shown in FIG. 9, one axis in the screen circumferential direction is the temperature setting axis M1, the other axis is the air volume setting axis M2, and the other axis is the air outlet switching axis M3, which are independent of each other. The selected item group. And the operation state of an air conditioner system is set by selecting and designating one predetermined selection button in each of these axes M1 to M3. Note that the way of grouping the button groups at this time is not limited to grouping buttons arranged in the circumferential direction of the screen, and for example, a group of buttons arranged in the thickness direction of the screen can be grouped as one selection item. .

  In the case of such a modification, for example, when the one end (select button 51) is selected on the temperature setting axis M1, the vibrator 15 vibrates maximum, and the one from the one end to the other end. It may be set so that the vibration condition of the vibrator 15 when the selection button 12 is selected gradually decreases toward the (selection button 52). This is not necessarily limited to the temperature setting axis M1, but may be applied to the air volume setting axis M2 and the air outlet switching axis M3.

  -When the button display selection method of the user interface 5 is applied to another system, this target is not limited to the air conditioner system. For example, this may be applied to an operation panel of a car navigation system, and the application destination can be changed as appropriate.

The number of selection buttons 12, 12... Is not limited to the same number in the screen circumferential direction and the screen thickness direction, and can be arbitrarily changed.
The operation switch 7 is not limited to an on / off type switch, and may be a scale type (dial type) that outputs a detection signal corresponding to a knob operation amount continuously or stepwise.

  When the operation switch 7 can be operated in the biaxial direction, the operation direction at this time is not limited to the combination of the rotation operation direction and the push / pull operation direction. That is, any of various operation directions such as a rotation operation direction, a push-pull operation direction, and a lateral operation direction (slide operation direction) may be combined. Note that when the switch type of the operation switch 7 is changed, the button arrangement of the display 6 may be changed accordingly.

The operation switch 7 is not necessarily operable only in the two-axis direction, and may be three or more axes.
The button display of what is in the selected state among the plurality of song selection buttons 12, 12...
