Description

  The present invention relates to a technique for specifying a target to be controlled by a terminal device such as a multi-function telephone and performing various settings.

  In audio equipment such as AV amplifiers and monitors, in recent years, setting and operation of various functions are becoming more complicated as functions and functions are increased. Therefore, in order to eliminate such complications of operations and the like, for example, when a user gives a movement like a gesture by holding a remote control (terminal device) in his / her hand, various operations are performed on a television receiver or the like. A technique for performing adjustment and setting has been proposed (see Patent Document 1).

JP 2007-251893 A

  In the above technique, setting and operation are still complicated, and there is room for simplification of operation. The present invention has been made in view of such circumstances, and one of its purposes is a terminal device that simplifies settings and operations, audio signal processing including the terminal device, and a computer. The object is to provide a program that operates as the terminal device.

  In order to achieve the above object, the terminal device according to the first aspect of the present invention is a terminal device capable of communicating with a processing device that controls each of a plurality of objects, wherein any one of the plurality of objects is selected. A specifying unit that specifies the posture of the device itself; and a control amount conversion unit that converts a change amount of the posture into a control amount for a predetermined control item when the posture of the device changes. Specific information indicating the target specified by the control unit and control amount information based on the control amount are transmitted to the processing device, and the processing device is controlled by the processing device.

According to this aspect, the control target is specified by the attitude of the terminal device, and when the terminal device changes to the attitude of the terminal device, the control target is converted into the control amount corresponding to the change amount.
For this reason, from the viewpoint of the user, it is possible to control from the specification of the control target to the designation of the control amount in the device by the attitude of the terminal device and the attitude change.
Note that the object of control and the control item are common in terms of the concept of being controlled, but the object of control is a higher concept than the control item. For example, when the processing device is an audio signal processing device, if the control target is a channel, the control item is a volume or sound range that is a lower level control target for that channel.
Further, the control amount means an increase / decrease amount from the current set value in the control. For this reason, the control amount information based on the control amount may be information indicating the control amount itself, or may be a set value increased or decreased by the control amount.

The said aspect WHEREIN: It is good also as a structure provided with the operation reception part which designates the said control item by operation from a user. According to this configuration, the control item can be specified according to the user's intention.
In this configuration, the control amount conversion unit may convert a posture change amount after a predetermined operation is performed on the operation receiving unit into the control amount. Thereby, the user can change the attitude of the terminal device in consideration of the beginning of the attitude change. The predetermined operation includes touch-on to the terminal device. Further, the end of the posture change may be designated by an operation different from the predetermined operation. Examples of such operations include touch-off.

  The present invention can be conceptualized not only as a terminal device but also as an audio signal processing system including the terminal device and an audio signal processing device as a processing device, and a program of a terminal device including a processor. The program may be stored in a recording medium.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a block diagram illustrating a configuration of an audio system according to the embodiment. As shown in this figure, in addition to the audio signal processing device 40, the audio system 1 includes a terminal device 10, a playback unit 20, a monitor 30, and speakers 51 to 55 corresponding to, for example, five channels.
The audio signal processing device 40 is a so-called AV amplifier, and the volume and the sound range can be adjusted for each audio signal of five channels. The five channels are FL (front left), C (center), FR (front right), SL (surround left), and SR (surround right). Although the subwoofer is omitted, the subwoofer may be installed to have 5.1 channel or may be other than 5 (5.1) channel.

The terminal device 10 is a mobile phone operated by a user, for example. In the present embodiment, the user designates a channel to be controlled in the audio signal processing device 40 by pointing the terminal device 10 to a speaker corresponding to the channel, and changes the posture of the terminal device 10. The control amount (the operation amount such as the volume) of the channel is designated.
The terminal device 10 is a computer having a processor, a memory, and the like. For example, a predetermined application program downloaded from a specific site on the Internet is installed in advance. When the application program is executed by a predetermined operation, in the terminal device 10, as shown in the figure, the management unit 12, the identification unit 13, the control amount conversion unit 15, the operation reception unit 17, and the position information management table TB12 And the functional block of the set value management table TB13 is constructed. The terminal device 10 includes a detection unit 11 and a display unit 16 in addition to these functional blocks.

  In FIG. 1, the detection unit 11 is a collective term for a gyro sensor for detecting the attitude and the like of the terminal device 10, a GPS (Global Positioning System) for detecting the location of the terminal device 10, and the like. Of these, the gyro sensor outputs, for example, three-axis angle information in the terminal device 10, and the GPS outputs position information of longitude, latitude, and altitude (height).

FIG. 2 is a diagram illustrating the angle of the terminal device 10 detected by the detection unit 11, particularly the gyro sensor. 2A is a plan view of the terminal device 10, FIG. 2B is a front view, and FIG. 2C is a right side view.
As shown in this figure, the gyro sensor detects the rotation angle for each of the three axes of the X axis, the Y axis, and the Z axis that are orthogonal to each other through the center of the casing of the substantially rectangular parallelepiped terminal device 10. Specifically, for example, a counterclockwise rotation angle in the figure around the Z axis from the display unit 16 toward the viewing direction (the thickness direction of the casing) is a yaw angle (yaw), and Y in the longitudinal direction of the casing While detecting the counterclockwise rotation angle around the axis as the roll angle (roll) and the counterclockwise rotation angle around the X-axis of the casing as the pitch angle (pitch), respectively, The detected angle information is output.
Note that the detection unit 11 may be used in combination with an angle sensor that outputs information on an angle with respect to a reference direction such as a geomagnetic direction or a gravity direction.

The display unit 16 is a flat display such as a liquid crystal display device or an organic EL (Electro Luminescence) device, and displays various types of information.
The operation reception unit 17 outputs operation information regarding an operation given to the touch panel from an output of a touch panel (not shown) superimposed on the display unit 16.

  The management unit 12 mainly has the following functions. Specifically, the management unit 12 firstly controls and manages each unit according to operation information from the operation receiving unit 17, secondly controls the display content of the display unit 16, and 3, a function of supplying angle information by the detection unit 11 to the specifying unit 13 or the control amount conversion unit 15, and a function of causing the communication unit 18 to transmit and receive various information to the audio signal processing device 40. Have

The specifying unit 13 specifies the attitude of the terminal device 10 from the angle information supplied by the detecting unit 11 via the management unit 12. For this specification, the specifying unit 13 refers to the position information management table TB12 as necessary. Although not shown, position information of the speakers 51 to 55 is registered in advance in the position information management table TB12, and user position information is registered as appropriate. In addition, these positional information is measured using the positioning function of the terminal device 10, for example.
The control amount conversion unit 15 calculates a change amount of the posture in the terminal device 10 from the supplied angle information, converts the change amount into a control amount, and returns the change amount to the management unit 12.
The communication unit (transmission unit) 18 transmits information supplied from the management unit 12 to the audio signal processing device 40 by, for example, short-range wireless communication, and receives various information from the audio signal processing device 40.
Although the details will be described later, the set value management table TB13 stores set values such as volume and range for every five channels.
The terminal device 10 is not limited to a mobile phone, and may be a tablet computer or a PDA (Personal Digital Assistant).

  The reproduction unit 20 generates a reproduction signal by reproducing various media such as a CD (compact disk), a DVD (digital versatile disk), and a BD (blu-ray disk) or by receiving broadcast radio waves. To do. The reproduction signal includes an audio signal and a video signal depending on the reproduction medium. The monitor 30 is a liquid crystal display device, a plasma display, or the like, and displays a video based on a video signal included in the reproduction signal.

  On the other hand, the audio signal processing device 40 includes a communication unit 41 and an amplification unit 48, and also includes a processing unit 47 such as a DSP (Digital Signal Processor) that executes control according to firmware. Among these, the communication unit (reception unit) 41 receives information transmitted from the communication unit 18 of the terminal device 10. The processing unit 47 decodes the audio signal included in the reproduction signal from the reproduction unit 20 into, for example, a 5-channel audio signal, and outputs the audio signal with a volume or a sound range according to the setting value stored in the setting value management table TB23.

FIG. 3 is a diagram illustrating an example of storage of setting values in the setting value management table TB23 (TB13). In the example of this figure, set values such as volume and range are stored for every five channels. In this example, the sound volume stores, for example, a numerical value from the lowest “0” to the highest “99”. The sound range includes “Bass” for emphasizing the low frequency range and “Treble” for adjusting the high frequency range. For example, numerical values from “−20” to “+20” are stored.
The front panel of the audio signal processing device 40 is provided with knobs (not shown) for individually setting the volume and the sound range, and set values corresponding to the positions of these knobs are stored in the set value management table TB23. Is done.
When the setting value stored in the setting value management table TB23 is changed in the audio signal processing device 40, the setting value is supplied to the terminal device 10 via the communication units 41 and 18 in order, and the setting value management table TB13. The set value stored in is also updated. On the contrary, when the setting value stored in the setting value management table TB13 is changed in the terminal device 10, the setting value is supplied to the audio signal processing device 40 via the communication units 18 and 41 in order. The set value stored in the management table TB23 is also updated. That is, the set value management tables TB13 and TB23 are configured such that the set values are synchronized with each other.

FIG. 4 is a diagram showing a positional relationship between the speakers 51 to 55 and the user L in a state where the listening room where the speakers are installed is viewed in plan.
As shown in this figure, each of the speakers 51 to 55 corresponds to the FL, C, FR, SL, and SR channels in order. More specifically, a C-channel speaker 52 is installed at substantially the center of the display surface of the monitor 30, and as viewed from the user L, an FL-channel speaker 51 is on the left side of the monitor 30, and an FR-channel speaker 53 is on the right side. The SL channel speaker 54 is installed on the left rear side of the user L, and the SR channel speaker 55 is installed on the right rear side.

Next, the operation of the audio system 1 will be described.
FIG. 5 is a flowchart showing the operation of the audio system 1 separately for each of the terminal device 10 and the audio signal processing device 40.
Here, the user who carries the terminal device 10 is located in the vicinity of the audio signal processing device 40, and between the terminal device 10 (the communication unit 18 thereof) and the audio signal processing device 40 (the communication unit 41 thereof). Assume that near field communication is already established.
In the terminal device 10, a main routine including the following steps Sa11 to Sa14 is repeatedly executed, for example, four times per second by the application program. Further, details of step Sa12 in the main routine are shown in FIG. 6, and details of step Sa14 are shown as subroutines in FIG.

  First, in the terminal device 10, the management unit 12 determines whether or not the channel to be controlled in the terminal device 10 has not been determined (unconfirmed) (step Sa11). When step Sa11 is executed for the first time, the determination result is “Yes”. Further, even if the channel to be controlled is once determined, if the operation for changing the determined channel is performed, the determination result is similarly “Yes”. Here, the operation to change the channel includes, for example, a touch operation on a predetermined area (software button) on a menu screen (not shown).

If the channel to be controlled is fixed (if the determination result in step Sa11 is “No”), the processing procedure skips to step Sa14.
On the other hand, if the channel to be controlled is unconfirmed (if the determination result in step Sa11 is “Yes”), the management unit 12 executes a process of setting (provisionally determining) the channel to be controlled ( Step Sa12). Details of step Sa12 will be described later.

Next, in a state where a channel to be controlled is set, the management unit 12 determines whether or not an operation for confirming the channel as a control target has been performed (step Sa13). As an operation for confirming, for example, a user touches a predetermined software button on the display screen of the display unit 16 as described later.
If the operation for confirming is not performed (when the determination result in Step Sa13 is “No”), the processing procedure returns to Step Sa12. In other words, the process of the next step Sa14 is not executed unless a channel is set as a control target and an operation for determining the set channel is performed.

  When the channel to be controlled has already been confirmed (when the determination result at step Sa11 is “No”), or when an operation for confirming the channel set as the control target has been performed (at step Sa13). When the determination result is “Yes”), the processing of the next step Sa14 is executed. In summary, in step Sa14, when the control item for the channel is set, first, the attitude change amount of the terminal device 10 is specified from the angle information by the detection unit 11, and secondly, the change amount is controlled. Third, among the setting values stored in the setting value management table TB13, the setting value corresponding to the control item for the channel to be controlled is changed by increasing or decreasing the control amount, and the fourth In addition, there are three pieces of information including audio signal processing: information indicating a channel to be controlled (specific information), information specifying a control item for the channel, and information indicating a control amount after change (control amount information). Transmitted to the device 40.

On the other hand, when the control item for the channel is not set in step Sa14, the setting value corresponding to the control item is not changed, and the above three pieces of information are not transmitted to the audio signal processing device 40.
Details of step Sa14 will be described later. Thereafter, the processing procedure returns to step Sa11 on the terminal device 10 side.

On the other hand, in the audio signal processing device 40, the processing unit 47 determines whether or not the three pieces of information are received from the terminal device 10 by the communication unit 41 (step Sb11). If not received (if the determination result in step Sb11 is “No”), the processing procedure returns to step Sb11. For this reason, the processing procedure does not proceed to the next step Sb12 until the communication unit 41 receives information from the terminal device 10.
If the information is received by the communication unit 41 (if the determination result of step Sb11 is “Yes”), the processing unit 47 controls the channel among the setting values stored in the setting value management table TB23. Increase or decrease the setting value of the item by the received control amount. As a result, the processing unit 47 adjusts and outputs the control items (volume and sound range) for the audio signal of the channel to be controlled to the set value after the change (step Sb12).

Thereafter, the processing procedure returns to step Sb11.
Therefore, in the audio signal processing device 40, step Sb12 is executed each time the communication unit 41 receives the three pieces of information from the terminal device 10.

Next, the details of the subroutine in step Sa12, that is, the channel setting will be described with reference to the flowchart of FIG.
First, in the terminal device 10, the management unit 12 determines whether or not the reference direction corresponding to the current operation point (listening position) has not been set (step Sc11).

In the present embodiment, when the user directs the Y axis of the terminal device 10 to any of the speakers 51 to 55, the channel of the directed speaker is set as a channel to be controlled.
On the other hand, when a user carrying the terminal device 10 tries to operate the audio signal processing device 40, the operation point is not necessarily unique. That is, the relative position of the operation point with respect to the speakers 51 to 55 is not uniquely determined.
Therefore, at the current operation point, the direction when the Y axis of the terminal device 10 faces the speaker 52 of the center (C), for example, is set as the reference direction when selecting the channel to be controlled.

Now, if the reference direction corresponding to the current operation point has been set (if the determination result of step Sc11 is “No”), the following steps Sc12 and Sc13 are not necessary, so the processing procedure is step. Skip to Sc14.
On the other hand, if the reference direction is not set (if the determination result in step Sc11 is “Yes”), the management unit 12 sets the reference direction as follows (step Sc12).

  Specifically, the management unit 12 first switches the screen to be displayed on the display unit 16 from a menu screen not shown to a screen as shown in FIG. Is communicated by message 60a. With this message 60a, as shown in FIG. 8, the user L touches the software button 62a with the Y axis of the terminal device 10 directed toward the speaker 52 at the center (C). When the touch operation information is supplied from the operation reception unit 17, the management unit 12 secondly, the information on the yaw angle and the location position output from the detection unit 11 at the time of the touch is stored in the work area ( (Not shown). Thereby, the angle information when the Y axis of the terminal device 10 is directed to the speaker 52 of the center (C) as viewed from the operation point, that is, information on the reference direction mc is acquired in association with the location.

Next, the management unit 12 sets a threshold direction (step Sc13). The threshold direction is used when determining whether the Y axis of the terminal device 10 is directed to any of the speakers 51 to 55 after setting the reference direction.
For this threshold direction, the management unit 12 first acquires the position information of the speakers 51 to 55 from the position information management table TB12 via the specifying unit 13, and the speakers adjacent to each other from the current operation point. An imaginary direction connecting the intermediate points is defined as a threshold direction. Specifically, as shown in FIG. 9, the management unit 12
The direction from the operation point toward the middle point of the speakers 51 and 52 is defined as a threshold direction m12,
The direction from the operation point toward the middle point of the speakers 52 and 53 is defined as a threshold direction m23,
The direction from the operation point toward the middle point of the speakers 53 and 55 is defined as a threshold direction m35.
The direction from the operation point toward the middle point of the speakers 55 and 54 is defined as a threshold direction m54.
The direction from the operation point toward the middle point of the speakers 54 and 51 is defined as a threshold direction m41.
The angle ranges defined by these threshold directions m12, m23, m35, m54, and m41 are set.

When the reference direction mc and the threshold directions m12, m23, m35, m54, and m41 are defined, the management unit 12 determines the Y axis of the terminal device 10 from the reference direction mc as follows with respect to the specifying unit 13. It is made to deviate only and it is discriminated whether it is directed to any of the speakers 51 to 55 (step Sc14).
Specifically, the management unit 12 first displays a message 60b as shown in FIG. 12A on the display unit 16 to notify the user of the action to be taken. By this message 60b, the user L directs the Y axis of the terminal device 10 to the speaker of the channel to be controlled.
The management unit 12 acquires the yaw angle information output from the detection unit 11 and supplies the information to the specifying unit 13 together with the threshold direction information. The specifying unit 13 corresponds to the reference direction mc in the direction indicated by the yaw angle. From the deviation angle, it is determined whether it belongs to any of the angle ranges defined by the threshold directions m12, m23, m35, m54, m41, and the determination result is supplied to the management unit 12.
For example, as shown in FIG. 10, it is assumed that the user L has rotated the Y axis of the terminal device 10 counterclockwise from the reference direction mc by an angle θ in plan view. In this state, since the direction rotated by the angle θ from the reference direction is within the angle range from the threshold direction m12 to the threshold direction m41, it is determined that the direction is directed to the front left (FL) speaker 51.

Next, the management unit 12 sets (provisionally determines) a channel (speaker) corresponding to the angle range to which the direction indicated by the yaw angle belongs according to the determination result by the specifying unit 13 (step Sc15). Note that after step Sc15, the processing procedure proceeds to step Sa13 of the main routine described above, and it is determined whether or not an operation for confirming the channel as a control target is performed.
On the other hand, when the user L points the terminal device 10 toward one of the speakers, the management unit 12 determines that the user L is currently pointing, for example, as illustrated in FIG. A screen indicated by a thick line is displayed on the speaker (channel), and the user L is confirmed. In the example of the figure, it is shown that the speaker to which the terminal device 10 is directed corresponds to FL.

When the user L touches the software button 63a on the screen of FIG. 12B with the Y axis of the terminal device 10 facing the speaker of the channel to be controlled, the determination result of step Sa13 described above is obtained. With “Yes”, the management unit 12 determines the speaker (channel) specified by the specifying unit 13 at the time of the touch as a control target.
If the user L does not operate any of the software buttons 63a and 63b on the screen of FIG. 12B, the processing procedure circulates through step Sa12, that is, the channel setting process in FIG. The process of determining which channel the speaker is directed to is continued.
On the other hand, when the software button 63b is operated, for example, the screen may be returned to the screen of FIG. 11, and the setting of the reference direction mc may be performed again.

  By the way, if the channel to be controlled is determined, the management unit 12 executes control / adjustment / transmission processing for the control item for the channel (step Sa14). Then, the details of the subroutine in step Sa14, that is, the control item control / adjustment / transmission process will be described with reference to the flowchart of FIG.

First, in the terminal device 10, the management unit 12 causes the display unit 16 to display a screen as shown in FIG. 13, for example (step Sd11). On this screen, the message 60c for notifying the user of actions to be taken, the message 60c, software buttons 64, 65, 66 for selecting control items, and the control / adjustment process are terminated, and the main And a software button 67 for designating returning to the routine (see FIG. 5).
The software button 64 designates a volume, the software button 65 designates a bass range, and the software button 66 designates a treble treble as control items.

  The management unit 12 determines whether any one of the software buttons 64, 65, 66, and 67 is touched from the operation information by the operation reception unit 17 (step Sd12). If any one of the software buttons 64, 65, 66, and 67 is not touched (if the determination result of step Sd12 is “No”), the process of step Sd12 circulates. In other words, the subsequent processing is not executed unless any of the software buttons 64, 65, 66, and 67 is touched. When the software buttons 64, 65, 66, and 67 are touched (when the determination result of step Sd12 is “Yes”), the management unit 12 first determines whether or not the touched button is the software button 67. Is determined (step Sd13).

When the touched button is the software button 67 (when the determination result in step Sd13 is “Yes”), the setting / adjustment process in step Sa14 ends, and the processing procedure returns to step Sa11 in FIG. . In this case, if the setting value corresponding to the control item is not changed, the communication unit 18 does not transmit any information even if the process proceeds to step Sa14.
On the other hand, when the touched button is other than the software button 67 (when the determination result of step Sd13 is “No”), that is, when any of the software buttons 64, 65, 66 is touched, the management unit 12 acquires the angle information of the detection unit 11 at the time of the touch operation (touch-on), and temporarily stores the angle information in a work area (not shown) of the memory (step Sd14). Thereby, the angle information of the posture state when any of the software buttons 64, 65, 66 is touched is acquired.

  Next, the management unit 12 determines whether or not a finger or the like has been released from the touched software button from the operation information by the operation reception unit 17 (step Sd15). If the finger or the like is not removed from any of the touched software buttons 64, 65, and 65 and the touch state is maintained (if the determination result in step Sd15 is “No”), the process proceeds to step Sd14. Processing cycles. On the other hand, when a finger or the like is released from any of the touch-operated software buttons 64, 65, 65 and the touch operation is released, that is, when touch-off is performed (when the determination result in step Sd12 is “Yes”), The management unit 12 acquires angle information of the detection unit 11 at the touch-off time (step Sd16).

Then, the management unit 12 supplies the angle information at the time of touch-on acquired in step Sa13 and the angle information at the time of touch-off acquired this time to the control amount conversion unit 15, and the control amount conversion unit 15 has 2 The two posture states are compared to calculate how much the pitch angle has changed (step Sd17).
For example, as shown in FIG. 14A, any one of the software buttons 64, 65, 66 with the user pointing the Y axis of the terminal device 10 in the direction indicated by the symbol A (the direction of the speaker 51). After touching (omitted in FIG. 14), as shown in FIG. 14B, the Y-axis is changed in the direction indicated by the upward sign B and shown in FIG. As shown, when the finger is released from the touched software button (when touched off), the angle θa from touch-on to touch-off is calculated as the angle change amount.
In FIG. 14, the user holds the terminal device 10 with the left hand and touches the software button with the index finger of the right hand, but it goes without saying that the user may hold and touch with only one hand.

  Subsequently, the control amount conversion unit 15 converts the calculated angle change amount into an amount (control amount) by which the set value for the control item of the channel to be controlled is increased or decreased (step Sd18). Here, the increase / decrease of the set value (the positive / negative of the control amount) is positive when the pitch angle is changed in the counterclockwise direction in FIG. 2C, that is, in the clockwise direction in FIG. And

As an example of converting the angle change amount to the control amount, for 10 degrees of the angle change amount, the set value is increased or decreased by, for example, “10” if the volume is set, and if the volume is Bass or Treble, the set value is changed. A simple proportional distribution such as increasing or decreasing by “4” is conceivable.
Further, in a simple proportional distribution, the angle change amount of the terminal device 10 is approximately the maximum angle that can be given by the wrist twist from the state where the user holds the terminal device 10 as shown in FIG. It may be normalized by the adjustment range of the set value by dividing by a range of ± 90 degrees. For example, if the control item is volume, the adjustment range of the set value is “0” to “99”, and the adjustment range is “100”, so that the Y axis of the terminal device 10 is upward (the pitch angle is increased). If the posture changes by 18 degrees (in the direction of), the angle change amount of 18 degrees is converted into a control amount “+10”.
Further, in accordance with the temporal change (speed) of the angle change, a configuration may be adopted in which the control amount is increased when it is fast, and the control amount is decreased when it is slow.

Subsequently, the control amount conversion unit 15 supplies the converted control amount to the management unit 12, and the management unit 12 accesses the setting management table TB13 and sets the setting value corresponding to the control item for the control target channel. Is increased / decreased by the control amount (step Sd19).
Then, as described above, the management unit 12 includes three pieces of information: identification information indicating a channel to be controlled, information specifying a control item for the channel, and control amount information indicating a changed control amount. Is transmitted to the communication unit 18, and the communication unit 18 transmits these pieces of information to the audio signal processing device 40 (step Sd20). After this, the processing procedure returns to step Sd12.

When these three pieces of information are received, the audio signal processing device 40 increases or decreases the setting value of the control item for the channel among the setting values stored in the setting value management table TB23 by the received control amount. At the same time, the control item of the audio signal of the control target channel is changed to the set value after being increased or decreased (step Sb12) as described above.
Therefore, for example, when the channel to be controlled is FL and the software button touched on and touched off is the software button 64 corresponding to the volume (see FIG. 13), the angle change amount θa is +18 degrees. When the angle change amount is converted to “+10” as the control amount, the sound volume changes from the set value corresponding to “25” to the set value corresponding to “35” increased by “10”.

  Here, the case where the software button 64 (see FIG. 13) corresponding to the sound volume is operated and the sound volume is changed has been described as an example. However, if the software button 65 corresponding to Bass is operated, for example, When the software button 66 corresponding to Treble is operated, the high sound range is adjusted.

As described above, according to the present embodiment, the channel to be controlled is specified by the attitude of the terminal device 10, and when the attitude of the terminal device 10 changes, the angle change amount associated with the attitude change becomes the control amount. The information indicating the control amount is supplied to the audio signal processing device 40. Then, in the audio signal processing device 40, the control items of the audio signal of the channel to be controlled are adjusted by increasing / decreasing the set amount by the control amount. For this reason, since the user can control from the specification of the channel to be controlled to the designation of the control amount in the channel by the attitude of the terminal device 10, it is easy for the user to understand, and Operation and the like can be simplified.
In the embodiment, the control items such as volume, bass, and treble are selected as the software buttons 64, 65, and 66. However, these control items may be specified by the attitude of the terminal device 10. However, in the embodiment, since the channel to be controlled is selected based on the attitude of the terminal device 10, the control item is not an attitude, but a touch operation on the display screen, that is, an instruction from the operation reception unit 17. The configuration according to is considered preferable.

<Application and modification>
The present invention is not limited to the above-described embodiments, and various applications and modifications as described below are possible, for example.

<Control items and setting timing>
In the embodiment, the volume, volume, bass, and treble that are control items are selected after the channel to be controlled is determined. However, the control item is selected before the channel to be controlled, and then the control is performed. The order of selecting / determining the target channel and acquiring the control amount by changing the posture may be used.

<Control items and angle information>
In the embodiment, the setting value of the volume and the sound range is increased / decreased depending on the pitch angle of the terminal device 10, but is not limited to the pitch angle, and may be a roll angle or a yaw angle. For example, if the setting value is increased or decreased according to the roll angle, the terminal device 10 can be operated as if it were a circular knob.
Further, for example, a pitch angle, a roll angle, and a yaw angle may be associated with each of the volume, bass, and treble, and each setting value may be increased or decreased individually according to the amount of change in the angle.

<Display on terminal device>
In the terminal device 10, the management unit 12 causes the display unit 16 to display a setting value based on the amount of angle change from the touch-on time when the posture is changed. It may indicate whether to increase or decrease.
For example, when the touch-on is performed, the screen may be switched to a screen as shown in FIG. 15, and the bar 71 indicating the volume setting value may be slid on the screen according to the posture change. Further, the bar 71 may be slid on the screen by touching to directly instruct to increase or decrease the volume.
Also, as shown in FIG. 16, a bar corresponding to each of volume, bass, and treble may be displayed, and a slide display may be made in accordance with a change in attitude of the terminal device 10, or by touching these bars, You may comprise so that an increase / decrease in volume and a sound range may be instruct | indicated.

<Setting / resetting the reference direction>
In the embodiment, if the reference direction is set (if the determination result in step Sc11 in FIG. 6 is “No”), the terminal device direction is acquired, but the general 5 (5.1) is used. ) For channels, the positional relationship between the speaker arrangement and the listening position may be recommended in advance. In such a case, if it is assumed that the user operates the terminal device 10 at the recommended listening position with respect to the recommended speaker arrangement, the reference direction is automatically determined. Also good.
Further, even if the reference direction has been set in the past, there is a possibility that the current position is moved from the position at the time when the reference direction is set. Therefore, even if the reference direction is set in the determination in step Sc11, the location of the user (terminal device 10) at the time of the determination is more than the threshold distance compared to the past location at the time of the setting. If so, the processing procedure may be shifted to step Ss12 to reset the reference direction.

<Threshold direction, etc.>
In the embodiment, since the threshold direction is set as shown in FIG. 9, one of the channels (speakers) to be controlled is specified according to the Y axis of the terminal device 10. . Regardless of this, a dead zone where the channel cannot be specified may be set by additionally setting the threshold direction. For example, as shown in FIG. 17, threshold directions m41a and m41b are set in the range from the speaker 51 to the speaker 54, and the Y axis of the terminal apparatus 10 is set to an angular range θ− from the threshold direction m41a to the threshold direction m41b. If it is ins, it is good also as a structure which does not specify the channel (speaker) which is a control object. Similarly, the threshold directions m35a and m35b are set in the range from the speaker 53 to the speaker 55, and if the Y axis of the terminal device 10 is within the angle range from the threshold direction m35a to the threshold direction m35b, A configuration may be adopted in which a certain channel (speaker) is not specified.
For example, when the speakers 51, 52, and 53 are arranged close to each other, the angles of the threshold directions m12 and m23 are narrowed, and as a result, it may be difficult to select the center (C) as a channel to be controlled. . In such a case, the angles of the threshold directions m12 and m23 may be increased. When setting the angles of the threshold directions m12 and m23 to be widened, for example, the threshold directions m12 and m23 are set at points that divide the angle range determined by the threshold directions m41 (m41a) and m35 (m35a) into approximately three equal parts. The angle range when selecting the front left (FL), center (C), and front right (FR) as the target may be equalized.

<Others>
In the embodiment, the control amount indicating the increase / decrease relative to the setting value of the control item is supplied to the audio signal processing device 40. However, the setting value itself increased / decreased by the control amount is supplied to the audio signal processing device 40. Also good. That is, the control amount information supplied from the terminal device 10 to the audio signal processing device 40 may be information indicating the control amount itself, or information indicating a value after the set value is increased or decreased by the control amount. Also good.
In the embodiment, the control target is the audio signal channel, but other channels may be used. Further, although the control items are the volume and sound range of the channel to be controlled, items such as an equalizer and a delay amount may be used. That is, an item determined by a control target may be set as a control item. For example, the control target may be an air conditioner, lighting, etc., while the control item may be air conditioning, heating, dehumidification, set temperature, air volume, etc. if it is an air conditioner, and brightness etc. if it is illumination.
