Description

  The present invention relates to an effect adding device that adds an effect to a music signal such as a musical tone signal, and more particularly to an effect adding device that is user-friendly using display technology.

  Some conventional effect-adding devices make it possible to adjust two-dimensional parameters by using a planar position sensor. That is, when the x-coordinate and y-coordinate are changed by manually operating the planar position sensor, the preset program changes according to the operation of the planar position sensor, so that the user can achieve the desired effect with a simple touch panel operation. This is a convenient device that can perform addition (see, for example, Patent Document 1).

Japanese Unexamined Patent Publication No. 2000-250539 (page 3-6, FIG. 4)

  Certainly, according to the conventional device, it is possible to change the type and amount of effect addition by performing a simple touch panel operation, but it is possible to notify the user's touch position etc. according to the touch feeling. No consideration has been given. That is, it has not been actively performed to inform the user of the touch position and various information.

  Therefore, the present invention has been made to solve such a conventional problem, and an object of the present invention is to provide an effect adding device that makes it easy to visually grasp a user's touch operation state.

In order to achieve the above object, the present invention provides an effect adding device for adding an effect to a supplied music signal.
A light emitting means comprising a plurality of light emitting portions arranged in a matrix in plan view;
Position information detecting means for two-dimensionally detecting an operator's touch position on the touch panel disposed above the light emitting means and outputting corresponding two-dimensional position information;
And a control means for driving and controlling the light emitting means so that the touch position can be visually discriminated based on the two-dimensional position information from the position information detecting means.

  According to the present invention, the control means detects the operator's touch position on the touch panel disposed above the light emitting means in a two-dimensional manner and outputs the corresponding two-dimensional position information. Since the light emitting means is driven and controlled so that the touch position can be visually determined based on the information, the touch position can be easily grasped visually.

  More specifically, the touch position can be easily grasped by causing the light emitting unit around a certain light emitting unit corresponding to the two-dimensional position information to be in a lighting state. Moreover, in the said apparatus, since the smoke glass was provided between the touch panel and the light emission means, it becomes possible to prevent that an internal structure is visible from the apparatus outer side. Furthermore, in the above-described apparatus, the reflection is further improved by providing a reflector formed so that each of the plurality of light emitting units is a quadrangle in a plan view and the area of the quadrangle in a plan view becomes smaller as it goes downward in the vertical direction. An efficient reflector structure can be obtained. When the controller determines that all the controls provided in the apparatus have not been used for a predetermined time, each light emitting unit is controlled to be lit with a preset light emission pattern. By controlling the driving of the light emitting means, it is possible to display a device non-use demonstration screen.

  According to the present invention, it is possible to provide an effect adding device that makes it easy to visually grasp the user's touch operation state.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  2 is a perspective view of the effect adding device 1 according to the embodiment of the present invention, FIG. 3 is a cross-sectional view taken along arrow AA in FIG. 2, and FIG. 4 is a plan view of the LED group and the reflector 8. The apparatus 1 includes a large number of operating elements 20 and operating elements 30 on the lower side and the upper side of the casing 2. In FIG. 2, the LED matrix group and the reflector are shown in the central portion in plan view, but the internal structure is hardly seen from the outside by the smoke glass 12 or the like. That is, FIG. 2 shows the internal structure for convenience of understanding the structure.

  As shown in FIG. 2, eight LEDs 6 are provided on the upper surface of the substrate 4 at appropriate intervals. Since FIG. 2 is a cross-sectional view, only eight LEDs 6 are shown, but actually, as shown in FIG. 3, eight horizontal directions (x direction), eight vertical directions (y direction), that is, The LEDs 6 are provided in a matrix of 8 rows and 8 columns. That is, a total of 64 LEDs 6 are provided. Each LED 6 is provided with a reflector 8 formed so that the area of the square in plan view becomes smaller as it goes downward in the vertical direction as it goes downward in the vertical direction (in a mortar shape). To reflect. The reflector 8 is integrally formed, and can be disposed on the upper side of the LED group so that the LED 6 can be seen from the upper side.

  Further, as shown in FIG. 3, a diffusion sheet 10 is placed on the upper part of the reflector 8 so as to diffuse light gently as a whole so that the LED 6 cannot be directly seen from the outside. A smoke glass 12 is placed on the diffusion sheet 10 and a touch panel 14 is placed thereon. The smoke glass 12 also makes it impossible to grasp the internal structure from the outside. Although not shown in FIGS. 1 and 2, when the touch operation is performed on the touch panel 14, a planar position sensor 140 is provided for detecting the two-dimensional coordinates by a change in resistance value, capacitance, or the like. ing. The configuration of the planar position sensor 140 itself that includes the touch panel 14 and outputs two-dimensional touch position information is a public technology.

  Next, the configuration of the signal processing system of the present apparatus 1 will be described. FIG. 1 is a block diagram of the signal processing system of the present apparatus. An A / D converter 150 for analog / digital conversion of an input signal such as a musical tone signal, a D / A converter 155 for digital / analog conversion of a signal from the control unit 100, and a speaker for amplifying the converted analog signal 160. The control unit 100 is configured to be able to receive and grasp operation signals from the operator group 110 including the operator 20 and the operator 30 shown in FIG. 2, and to read and write required information. The storage unit 120 is configured to be controllable.

  In addition, a planar position sensor 140 that detects two-dimensional information of the touch position with respect to the touch panel 14 and sends the information to the control unit 100 is provided. As described above, the matrix LED group 130 includes a total of 64 LEDs 6 in 8 rows and 8 columns, and the control unit 100 is configured to be able to individually control the lighting of each LED 6. For example, the amount of current supplied to the LED 6 is adjusted so that the illuminance can be changed in eight stages from the minimum (lights off) to the maximum.

  FIG. 5 is an explanatory diagram of the table 500 stored in the storage unit 120. As shown in FIG. 4, X and Y coordinates are set with the upper left as the origin. At this time, it is this table 500 that sets which range of position information each LED 6 corresponds to. For example, when the two-dimensional position information is “a ≦ X ≦ b, c ≦ Y ≦ d”, the LED 6 with the LED number “LED1” becomes the LED 6 corresponding to the touch position. As described above, the table 500 associates each of the 64 LEDs 6 and the touch panel of 64 divisions into 14 touch panels.

(Operation)
Hereinafter, an example of the operation will be described. When an input signal such as a musical tone signal is input and digitally converted by the A / D converter 150, an effect is added to the digital signal by the control unit 100, and the effect added signal is converted by the D / A converter 155. Analog conversion is performed and sound is emitted from the speaker 160. For example, it is assumed that the effect addition amount changes according to the two-dimensional position of the touch operation.

  Now, when a certain position on the touch panel is touched, the two-dimensional position information (X, Y) from the planar position sensor 140 is sent to the control unit 100. The control unit 100 adds an effect with an effect addition amount corresponding to the two-dimensional position information. At the same time, the control unit 100 refers to the stored contents of the table 500 in FIG. 5 and grasps the LED 6 having the LED number corresponding to the two-dimensional position information. Then, as shown in FIG. 6, the four LEDs 6 around the LED 6 (see “T”) are turned on at the maximum illuminance (ON). That is, in this case, the two LEDs 6 surrounding the LED 6 corresponding to the touch position in the X-axis direction and the two LEDs 6 surrounding in the Y-axis direction are turned on with the maximum illuminance. The two LEDs surrounding the LED corresponding to the touch position in the X-axis direction have the same Y coordinate range as the Y coordinate range for the LED 6 corresponding to the touch position, and correspond to the LED 6 corresponding to the touch position. The two LEDs having the X coordinate range closest to the X coordinate range to be detected are grasped by the control unit 100 referring to the table 500. The two LEDs 6 surrounding the LED 6 corresponding to the touch position in the Y-axis direction are grasped in the same manner.

  And the control part 100 reduces this maximum illumination intensity gradually, for example in eight steps. Such illuminance information for each LED 6 is stored in the storage unit 120, and the brightness of each LED can be controlled by updating it appropriately. When a new touch operation is performed, the four LEDs around the LED 6 corresponding to the two-dimensional position information are newly lit at the maximum illuminance. If such a process is continued, it will be bright near the newest touch position and dark near the old touch position, and light will appear to tail as the touch position is changed due to the afterimage phenomenon.

  That is, the control unit 100 turns on the four LEDs 6 around a certain LED 6 corresponding to the two-dimensional position information, and gradually lowers the illuminance of the LED 6 that has been turned on. The touch position can be easily grasped.

(Other operation examples)
When no operation is performed on the apparatus 1 (for example, when it is determined that no operation element is operated within a predetermined time), the control unit 100 forms a matrix with a predetermined light emission control pattern. Lighting control of the LED group 130 can also be performed. That is, in a standby state, control may be performed so that a predetermined light emission pattern can be seen. In other words, the same function as a screen saver on a PC can be realized. Moreover, the light emission state of the LED group can be controlled to display characters by light.

  In addition, in the said embodiment, although it is an apparatus at the time of using 64 LED6, the number of LED is not restricted to these.

  As described above, according to the present invention, an effect adding device with better operability can be provided.
