Description

  The present invention relates to a terminal device and a method for controlling a plurality of sound sources, and more particularly to a terminal device that can simultaneously output signals from a plurality of sound sources and a method for controlling a plurality of sound sources.

  Conventionally, an apparatus having a function of simultaneously outputting signals from a plurality of sound sources has been proposed. For example, in Patent Document 1 below, by adjusting the sound mode (direction and sense of distance) for each sound source, each sound of a plurality of sound sources can be easily heard and a desired sound can be selected. A technique is disclosed.

  Further, in Patent Document 2 below, by controlling the volume of a plurality of sound sources, each sound source can be distinguished, and the tilting direction of the operation lever constituting the sound source selection instruction unit (that is, the reference line) In other words, there is disclosed a technique capable of switching the volume of each sound source of a plurality of sound sources based on the angle information).

  However, in Patent Documents 1 and 2, when sounds from a plurality of sound sources (for example, a radio receiving unit and a television receiving unit) are output at the same time, the sources (for example, the sound source is a radio receiving unit) in each of these sound sources. In this case, there is no particular description of a technique for switching the reception frequency and the sound source when the sound source is a TV receiver.

  Conventionally, the source in a sound source is switched by selecting a source (for example, a song) through a source selection screen for each sound source (for example, if the sound source is a CD, a CD playback screen). If this conventional technology is applied to output signals from multiple sound sources at the same time, to switch the source within a sound source, switch to the source selection screen for that sound source, select, etc. There is a problem that the operation of selecting the source in the sound source becomes complicated and time-consuming.

Some terminal devices equipped with a plurality of sound sources are equipped with a random playback function. Conventional random playback is performed within the same sound source (for example, a song on a CD is played randomly). In general, the source (reception frequency, reception channel, playback music) in each sound source is switched in a form that spans multiple sound sources (for example, a form that repeats radio → TV → CD). No technology for outputting an acoustic signal has been proposed so far.

Therefore, it is possible to easily select a source in each sound source that is output simultaneously through the input screen, and it is possible to improve user convenience.

  Embodiments of a terminal device and a method for controlling a plurality of sound sources according to the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram schematically showing a main part of a terminal device according to an embodiment.

  In the figure, reference numeral 1 denotes a terminal device. The terminal device 1 includes a plurality of sound sources 2a, 2b,... 2n, and a volume control unit 3 that adjusts the volume of a sound source signal output from the selected plurality of sound sources. , A synthesizing unit 4 that synthesizes (mixes) the sound source signals from the sound sources whose respective volumes are adjusted by the volume control unit 3, and an output unit that amplifies the sound source signal synthesized by the synthesizing unit 4 and outputs the amplified sound source signal to the speaker 6 5, a display unit 7 configured to include a display display 7a and the like, an operation unit configured to include a button switch 8a disposed on the display unit 7 and a touch panel 8b disposed on the display display 7a. 8 and control of the function of each unit based on an input signal or the like from the operation unit 8, for example, control over the sound sources 2a to 2n such as switching of a sound source outputting a sound source signal or switching of a source in the sound source, a volume control unit Volume adjustment control for 3 And it is configured to include a system control unit 9 for performing a display control for the display unit 7.

  The plurality of sound sources 2a to 2n include an AM receiver that receives AM broadcast waves, an FM receiver that receives FM broadcast waves, a TV receiver that receives TV broadcast waves, and a CD / DVD that plays CDs and DVDs. At least two or more sound sources of a deck, an MD deck for reproducing MD, a hard disk or semiconductor memory capable of reading / writing music files, and a cassette deck for reproducing cassette tape may be employed.

  The volume control unit 3 and the synthesis unit 4 are configured by a DSP that performs digital signal processing, and the system control unit 9 is configured by a microcomputer including a CPU, a RAM, and a ROM. A program for executing and various data are stored.

Next, a method for controlling a plurality of sound sources realized by the terminal device 1 according to the embodiment will be described with reference to FIGS.
First, when a multiple sound source output menu is selected through a predetermined menu screen or the like, the multiple sound source selection menu screen shown in FIG. 2 is displayed, and the user selects a sound source to be synthesized and output through this screen. Is possible.

  In the multiple sound source selection menu screen shown in FIG. 2, for example, when three sound source buttons of AM, FM, and TV are selected and then the enter button is input, the multi sound source output mode is entered and shown in FIG. The multiple sound source output mode screen is displayed. Through this screen, the user can appropriately switch the source in each of the displayed sound sources and adjust the sound volume for each sound source.

  When the power of the terminal device 1 is turned off in the state of the multiple sound source output mode, the setting state of the multiple sound source output mode is stored, and when the power is turned on next time, the previous setting state is read and the previous power is turned off. Multiple sound source output mode screen is displayed.

  In the multiple sound source output mode screen shown in FIG. 3, marks 10a, 10b, 10c (characters within a circle (sound source and its sound source) indicating a plurality of sound sources (TV, AM, FM) selected on the multiple sound source selection menu screen. Source) is displayed in a form positioned at the apex angle of the triangle, and is adjacent to each sound source mark 10a, 10b, 10c, and a source selection means for selecting a source in each sound source (this In this case, signs of + and-) 11a, 11b, and 11c are displayed.

  For example, when a touch input to the + sign corresponding to the sound source mark 10a of the TV is detected, the TV reception channel is controlled to move up, while when a touch input to the − sign is detected, the TV The information of the switched reception channel is displayed in the TV sound source mark 10a (in FIG. 3, 1 is displayed in the TV sound source mark 10a). Have been).

  Similarly, when a touch input to the + sign of the sound source mark 10b (or 10c) of the FM (or AM) is detected, the reception frequency (any receivable frequency or registered frequency) of the FM (or AM) is detected. ) Is controlled to be carried up, and when a touch input to the-sign is detected, the reception frequency of FM (or AM) is controlled to be carried down, and the information on the switched reception frequency is FM ( (Or AM) sound source mark 10b (or 10c) (in FIG. 3, 76.1 is displayed in FM sound source mark 10b, and 594 is displayed in AM sound source mark 10c). .

  FIG. 3 shows a case where a plurality of sound source marks 10a, 10b, and 10c are displayed in a circle and the source selection means 11a, 11b, and 11c are displayed with signs of + and −. The display form of the sound source mark and the source selection means is not limited to this form, and various designs and codes that are easy to recognize and identify for the user can be adopted.

  In addition, when three sound sources are selected, it is preferable that the sound source mark is displayed in a form positioned at the apex angle of the triangle. However, when two sound sources are selected, the sound source marks are displayed in the horizontal direction. When there are four or more selected sound sources, the sound source marks are displayed in a form positioned at the apex of a polygon such as a quadrangle.

  Further, through the multiple sound source output mode screen shown in FIG. 3, the user can adjust the sound volume for a plurality of sound sources. For example, the sound source mark 10a of the TV and the sound source mark 10b of the FM When an arbitrary position is touched, a distance ratio between the position (coordinates) on the screen where the touch is detected and the position (coordinates) of the sound source mark 10a of the TV and the sound source mark 10b of the FM is calculated, Based on the distance ratio, the volume (volume ratio) for the TV sound source and the FM sound source is adjusted. In the ROM of the system control unit 9, a table and a relational expression showing the relationship between the distance ratio and the volume adjustment ratio are recorded in advance, and the volume adjustment ratio for each sound source is based on the table and the relational expression. Is set. Note that the overall volume (absolute volume) adjusted by the output unit 5 can be adjusted by a main volume button provided in the button switch 8a.

  Furthermore, volume adjustment for a plurality of sound sources will be described with reference to FIG. 4. In this case, the approximate center of gravity of a triangle having the sound source marks 10a, 10b, and 10c as vertices, and the centers of the sound source marks 10a, 10b, and 10c. , The volume adjustment area of the sound source is divided into three, the area A is the setting area of the volume ratio of the TV sound source and the AM sound source, the area B is the setting area of the volume ratio of the TV sound source and the FM sound source, and the area C Are set in the volume ratio setting area between the AM sound source and the FM sound source.

  For example, when the point P on the screen shown in FIG. 4 is touched, the coordinates of the detected point P are determined to be within the region B, and the distance L1 between the point P coordinates and the sound source mark 10a of the TV is determined. The distance L2 between the P point coordinates and the FM sound source mark 10b is calculated, and the ratio between the volume of the TV sound source and the volume of the FM sound source is determined from the distance ratio between the distance L1 and the distance L2. For example, if L1: L2 = 1: 3, the reciprocal of the distance ratio is taken so that the volume of the sound source closer to the P point coordinate (in this case, TV) is increased, and TV sound source: FM sound source = 3: The volume ratio is set to 1, FM broadcast can be output as a sub sound source while TV broadcast is output as a main sound source, and the user can enjoy two broadcasts simultaneously while listening to TV broadcast and FM broadcast separately. Is possible.

  As shown in FIG. 3, on the multiple sound source output mode screen, ring-shaped volume marks (volume grasping means) 12a, 12b, 12c for grasping the volume of each adjusted sound source are displayed on the screen. The volume is displayed in the vicinity of each of the above sound sources, and the volume level is displayed with a volume mark so that the setting state of the volume ratio between the sound sources can be easily grasped visually. FIG. 3 shows a state in which signals from the TV sound source and the FM sound source are simultaneously output (a state in which a signal from the AM sound source is not output).

  In addition, the multiple sound source output mode screen shown in FIG. 3 is provided with a random button for switching to a mode in which sound is output while sequentially switching the source of each sound source in a form straddling a plurality of sound sources.

  When the random button is input, the screen is switched to the random output mode screen shown in FIGS. 5A to 5C, and a light beam is formed outward from the approximate center of gravity of the triangle having the sound source marks 10a, 10b, and 10c as vertices. The light mark 13 is displayed so as to rotate in a certain direction (in this case, the right direction) so as to draw a circle, and in association with the rotation of the light mark 13, processing for changing the sound volume for each sound source, The source switching process is performed in parallel.

  For example, as shown in FIG. 5A, when the light mark 13 is between the sound source mark 10a of the TV and the sound source mark 10b of the FM, the sound from the TV sound source and the FM sound source is output simultaneously, The volume ratio between the TV sound source and the FM sound source is changed in conjunction with the movement of the light mark 13. The volume ratio is, for example, the reciprocal of the distance ratio between the intersection of the light mark 13 and the line connecting the TV sound source mark 10a and the FM sound source mark 10b and the TV sound source mark 10a and the FM sound source mark 10b. The sound volume of the sound source decreases as the light mark 13 moves away from the sound source mark, while the sound volume of the sound source increases as the light mark 13 approaches the sound source mark. ing. In addition, ring-shaped volume marks 12a, 12b, and 12c for grasping the change in volume of each sound source at that time are displayed near the sound source marks 10a, 10b, and 10c on the screen. Therefore, it is easy to visually grasp the volume change between sound sources.

  When the light mark 13 exceeds the FM sound source mark 10b and enters the state shown in FIG. 5 (b), the sound from the FM sound source and the AM sound source is output at the same time. The volume ratio between the AM sound source and the TV sound source is changed in conjunction with the movement of the sound source. Similarly to the above, the volume ratio is the distance ratio between the intersection of the line 13 connecting the FM sound source mark 10b and the AM sound source mark 10c and the light mark 13, and the FM sound source mark 10b and the AM sound source mark 10c. The volume marks 12a, 12b, and 12c can be set so as to be reciprocal, and the sound volume marks 12a, 12b, and 12c for grasping the change in volume of each sound source at that time are positioned near the sound source marks 10a, 10b, and 10c on the screen. It is displayed.

  When the light mark 13 exceeds the sound source mark 10c of the AM and enters the state shown in FIG. 5C, the sound of the AM sound source and the TV sound source is output at the same time. The volume ratio between the AM sound source and the TV sound source is changed in conjunction with the movement. Similarly to the above, the volume ratio is the ratio of the distance between the intersection of the line 13 connecting the AM sound source mark 10c and the TV sound source mark 10a and the light mark 13, and the AM sound source mark 10c and the TV sound source mark 10a. The volume marks 12a, 12b, and 12c can be set so as to be reciprocal, and the sound volume marks 12a, 12b, and 12c for grasping the change in volume of each sound source at that time are positioned near the sound source marks 10a, 10b, and 10c on the screen. It is displayed.

  Further, in the random output mode, the sound sources to be simultaneously output are sequentially switched, and the source of each sound source is also sequentially switched in conjunction with the movement of the light mark 13. The light mark 13 is the sound source mark 10a of the TV. And FM sound source mark 10b (see FIG. 5 (a)), the reception frequency of the AM sound source can be switched (the switching frequency is selected at random even at the next set frequency). Set frequency).

  That is, when the light mark 13 is between the sound source mark 10a of the TV and the sound source mark 10b of the FM, the sound from the AM sound source is not output, and the reception frequency of the AM sound source is switched during this time.

  When the light mark 13 that exceeds the FM sound source mark 10b is moving between the FM sound source mark 10b and the AM sound source mark 10c (see FIG. 5B), the reception channel of the TV sound source is switched. (The channel to be switched may be the next channel or a randomly selected channel).

  When the light mark 13 that exceeds the AM sound source mark 10c is moving between the AM sound source mark 10c and the TV sound source mark 10a (see FIG. 5C), the reception frequency of the FM sound source is switched. (The frequency to be switched may be the next set frequency or a randomly selected set frequency).

  As described above, the terminal device 1 can perform random output (also referred to as zapping) control in which sound sources to be output simultaneously are switched (in a form extending over a plurality of sound sources), and the source of each sound source is also sequentially switched. It can be done.

  Further, when a predetermined stop operation (for example, a touch operation on the light mark 13 or the like) is detected during the random output of a plurality of sound sources, the random output process is stopped and the sound output in that state is continued. It is like that.

  Next, processing operations performed by the system control unit 9 in the terminal device 1 according to the embodiment will be described based on the flowcharts shown in FIGS. This processing operation is executed when the multiple sound source output mode is selected.

  First, it is determined whether or not there is a touch input to the multiple sound source output mode screen (step S1). If it is determined that there is no touch input, the process ends. If it is determined that there is a touch input, the coordinates input by touch input are determined. Is calculated (step S2), and the region to which the calculated touch coordinates belong is determined (step S3).

  If it is determined in step S3 that the touch coordinates belong to the area of the source selection means (+, − sign) of any sound source, that is, there is a touch input to the source selection means, the corresponding source selection means is supported. A process of switching the source in the sound source to be performed is performed (step S4), and then the process proceeds to step S5. For example, if it is determined that the touch coordinates belong to the area of the + sign of the FM sound source mark 10b, that is, there is a touch input for the + sign of the FM sound source mark 10b, the reception frequency of the FM sound source is raised and the next reception is performed. A process of outputting a control signal for switching the receiving station to the sound source (FM receiving unit) is performed so as to switch to the station. In step S5, a process of displaying the information of the newly switched source in the sound source mark is performed, and then the process ends.

  On the other hand, if it is determined in step S3 that the touch coordinates belong to one of the volume adjustment areas (any one of areas A to C shown in FIG. 4), the two sound sources corresponding to the volume adjustment area to which the touch coordinates belong. A distance ratio L1: L2 between the mark and the touch coordinates is calculated (step S6).

  In the next step S7, a volume ratio for each sound source is determined based on the calculated distance ratio L1: L2, and a volume adjustment signal including the determined volume ratio information is output to the volume controller 3 (step S8). Thereafter, the process proceeds to step S9. The volume control unit 3 adjusts the volume ratio of each sound source to be output based on the volume adjustment signal. In step S9, a process for displaying a volume mark for grasping the volume of each adjusted sound source at a position near each sound source mark on the screen is performed, and then the process ends.

  On the other hand, if it is determined in step S3 that the touch coordinates belong to the random button area, that is, there is a touch input to the random button, the process proceeds to random output processing (details will be described later) of a plurality of sound sources (step S10). After that, it is determined whether or not there has been a stop operation of random output processing of a plurality of sound sources (step S11). If it is determined that there is no stop operation, the processing of step S10 is repeated while it is determined that there is a stop operation. Then, output processing of a plurality of sound sources corresponding to the state at the time of the stop operation is performed (step S12), and then the processing is finished.

  Next, a random output processing operation of a plurality of sound sources performed by the system control unit 9 in the terminal device 1 according to the embodiment will be described based on the flowchart shown in FIG.

  First, in step S21, a light mark 13 is displayed at a position corresponding to the current output state of a plurality of sound sources, and then a signal is generated while changing the sound volume (volume ratio) in conjunction with the movement of the light mark 13. Is processed (step S22), and then a volume mark corresponding to the change in volume for each sound source is displayed (step S23).

  Thereafter, it is determined whether or not the light mark 13 exceeds the next sound source mark (step S24). If it is determined that the light mark 13 does not exceed the next sound source mark, the process returns to step S22 and repeats the process. If it is determined that the light mark 13 has passed the next sound source mark, a process of switching the sound source to be output is performed (step S25), and then the sound volume (volume ratio) for a plurality of sound sources is linked to the movement of the light mark 13. A process of synthesizing and outputting a signal while changing the sound is performed (step S26), and then a process of displaying a volume mark corresponding to a change in volume for each sound source is performed (step S27).

  Next, it is determined whether or not the light mark 13 exceeds a predetermined position (for example, the midpoint between the sound source marks) (step S28), and it is determined that the light mark 13 does not exceed the midpoint between the sound source marks. Then, the process returns to step S26 and the process is repeated. On the other hand, if it is determined that the light mark 13 has passed the midpoint between the sound source marks, a process of switching the source in the sound source of the sound source mark in the extension line direction of the light mark 13 is performed. (Step S29), then, the process returns to Step S22, and the process is repeated until a random output stop operation is detected.

  According to the terminal device 1 according to the above embodiment (1), when signals from a plurality of sound sources are synthesized and output, information on these sound sources (sound source marks 10a, 10b, 10c in FIG. 3), A plurality of sound source output mode screens including source selection means (+,-signs 11a, 11b, 11c in FIG. 3) for selecting the source in each of these sound sources are displayed, and for the source selection means 11a, 11b, 11c. Based on the input operation, the source in the corresponding sound source is switched. Therefore, it is possible to easily select sources in each sound source that are output simultaneously through a plurality of sound source output mode screens, thereby improving user convenience.

  Further, information on each sound source (sound source mark) is displayed at a predetermined interval on the screen, and based on the distance ratio between the position indicated on the screen via the touch panel 8b and each sound source mark on the screen, Since the volume for each sound source is adjusted, it is easy to adjust the volume of each sound source when signals from multiple sound sources are output simultaneously. The volume of the sound source can be adjusted.

  In addition, ring-shaped volume marks 12a, 12b, and 12c for grasping the volume of each sound source whose volume has been adjusted are displayed at positions near the sound source marks 10a, 10b, and 10c on the screen. The volume setting state of the sound source can be easily grasped visually.

  In addition, when a random button is operated on the multiple sound source output mode screen, the sound volume for each sound source on the screen is changed in a predetermined pattern, and the source in each sound source is set at a predetermined timing in conjunction with the volume change. The sound source can be randomly output from the sources in each sound source in a form that spans multiple sound sources, and the user can switch between multiple sound sources without switching the setting screen etc. The source can be listened to, and the sound source to be listened to and the source of the sound source can be easily selected on one operation screen.

  In addition, at the time of random output of a plurality of sound sources, a light mark 13 (moving display means) that moves in a circular pattern is displayed on the screen, and the volume ratio for each sound source is changed in conjunction with the movement of the light mark 13. In addition, the source of each sound source is switched while sequentially switching the sound source that is the source to be switched in conjunction with the movement of the light mark 13, so that the user can easily grasp the current output state through the screen can do.

  Even when a plurality of sound sources are output at random, the ring-shaped volume marks 12a, 12b, and 12c for grasping the volume of each sound source whose volume has been changed are displayed on the screen as the sound source marks 10a, 10b, and 10c. Since it is displayed in the vicinity, it is possible to easily grasp the change in volume of each sound source.

  When the terminal device 1 is adopted as an in-vehicle terminal device, the input interface function substantially similar to the multiple sound source output mode screen shown in FIG. 3 is used as a function for setting the volume and acoustic characteristics for each seat of the vehicle. FIG. 8 shows a display example of the sound setting screen for each seat.

  The sound setting screen for each seat has four seat marks (front seat (left) (right), rear seat (left) (right)) corresponding to the sound source mark, and volume control means (+, Through this screen, the user can output the sound from the speaker corresponding to the seat by touch input of the volume control means (signs of + and −) corresponding to each seat mark. The volume level can be adjusted.

  Each seat mark also has a function as a means (selection button) for selecting an acoustic characteristic of the DSP, and switches to an acoustic characteristic such as a concert hall, live, stadium,. It has become. Further, when the information on the acoustic characteristics of the DSP is displayed in the seat mark, the signs “+” and “−” function as means for adjusting the strength of the acoustic characteristics.

  Also, the adjustment of the absolute volume of the entire interior of the vehicle (adjustment of the volume between the seats) can be performed for each seat at a volume ratio determined according to the distance ratio between the touch position on the screen touched by the user and each seat mark. Can be distributed.

  Through such a seat-specific acoustic setting screen, the user can set the volume and acoustic characteristics for each seat, and the absolute volume between each seat can also be set between the touch position on the screen and each seat mark. It is possible to set according to the distance ratio, and it is possible to set the volume and acoustic characteristics that are visually easy to understand.

  Further, when the terminal device 1 is adopted as an in-vehicle terminal device, the input interface function substantially similar to the multiple sound source output mode screen shown in FIG. FIG. 9 shows a display example of the guidance sound source specific sound setting screen.

  On the sound setting screen for each guidance sound source, three guidance sound source marks (navigation, danger notice, road vehicle) corresponding to the sound source mark and guidance voice selection means (signs of + and-) corresponding to the source selection means are displayed. Has been. Through this screen, the user can input the type of guidance voice corresponding to the guidance function (male voice, female voice) by touch input to the guidance voice selection means (signs of +, −) corresponding to each guidance sound source mark. Voice, high voice, low voice, etc.) can be set.

  For example, when a touch input to a + sign corresponding to a guidance sound source mark of navigation is detected, control is performed so that the voice for route guidance is switched to male A (high voice), male B (low voice),. On the other hand, when a touch input to the-sign is detected, the route guidance voice is controlled to be switched to female A (low voice), female B (high voice),. . Similarly, + and-signs corresponding to danger notices and road and vehicle guidance sound source marks have a similar voice switching function, so that voices can be set according to user preferences. .

  “Danger notice” corresponds to a sound source for danger notice guidance based on monitoring by a monitoring means such as a radar or a camera. “Road car” is used for guidance of traffic information obtained by road-to-vehicle communication. Supports sound sources.

  Also, the user can set the volume ratio when simultaneously outputting each guidance sound source through this screen, for example, between the guidance sound source mark for navigation and the guidance sound source mark for danger notification. When an arbitrary position is touched, a distance ratio between the position (coordinates) on the screen where the touch is detected and the position (coordinates) of the guidance sound source mark for navigation and danger notification is calculated, and based on the distance ratio Thus, a volume ratio between the navigation sound source and the danger notification sound source is set.

  Therefore, when the navigation sound source and the danger notification sound source are output at the same time, if the guidance of the danger notification is used as the main sound source, the volume ratio can be set by touching the position near the guidance sound source mark of the danger notification. In addition, when the guidance sound of the navigation sound source is used as the main sound source, the volume ratio may be set by touching a position near the navigation sound source mark of the navigation.

  If such a setting is made, even when the guidance of the danger notice is implemented by interruption when the route guidance is performed by the navigation, the route guidance is performed at the volume ratio set through the above screen. The voice and the guidance voice of the danger notification can be output at the same time, and the user can listen to these voices separately.

  As described above, the volume ratio between the danger notification sound source and the road car sound source can be set based on the touch position between the danger sound source mark and the road car sound source mark. Based on the touch position between the mark and the guidance sound source mark of the navigation, the volume ratio between the road and vehicle sound source and the navigation sound source can be set.
