FIG. 2 is a diagram showing a first example of the internal configuration of the audio transmitter 20. As shown in FIG. FIG. 3A is a diagram showing a second example of the internal configuration of the audio transmitter 20. As shown in FIG. FIG. 3B is a diagram showing a third example of the internal configuration of the audio transmitter 20. As shown in FIG. FIG. 3C is a diagram showing a fourth example of the internal configuration of the audio transmitter 20. As shown in FIG. FIG. 3D is a diagram showing a fifth example of the internal configuration of the audio transmitter 20. As shown in FIG. FIG. 3E is a diagram illustrating a sixth example of the internal configuration of the audio transmitter 20. FIG. 3F is a diagram illustrating a seventh example of the internal configuration of the audio transmitter 20. In FIG. 2 and FIGS. 3A to 3F, it is assumed that the longitudinal direction and the vertical direction follow the arrows shown in FIG.

The voice transmitter 20 includes a voice ID selection dial 21, a volume indicator 22, a voice ID selection unit 23, a memory 24, a superimposed voice signal generation unit 25, a speaker 26, a directivity changing unit 27, and a trigger. And the button 28. As shown in FIG. 2, the audio transmitter 20 has, for example, a transmitter main body BDY1 having a total length of about 40 to 50 cm in the front-rear direction, and a grip portion HLD1 arranged to be inclined with respect to the transmitter main body BDY1.

The voice transmitter 20 is used, for example, in a state in which the holding unit HLD1 is held by the hand of the director REN1 (see FIG. 4) for enriching the atmosphere of the concert hall, and possessing some or all of the spectators in the concert hall By selecting the respective audio receivers 30 to transmit the superimposed audio signal (see later) as needed, the entertainment property is provided. Note that the transmitter body BDY1 can be easily grasped by the renderer REN1 over the entire length of the transmitter body BDY1 (for example, the length in which the main case 271 and the sub case 272 shown in FIG. 2 are connected in the front-rear direction) It is needless to say that the size is not limited to the range of 40 to 50 cm.

The voice ID selection dial 21 as an example of the voice ID instruction unit is constituted by a dial (in other words, a knob) disposed on the lower side of the cylindrical main casing 271, for example, and the finger of the user (for example, the performer REN1) Is a knob mechanism for selecting any one of the voice IDs by rotation. The voice ID selection dial 21 passes, for example, information indicating the rotation angle of the predetermined position of the knob to the voice ID selection unit 23.

In addition, the audio | voice ID selection dial 21 is not limited to being comprised by a knob mechanism, For example, you may be comprised by the button. In this case, the voice ID selection dial 21 selects a voice ID according to the number of times the user (for example, the effecter REN 1) presses the button and sends it to the voice ID selection unit 23.

The volume indicator 22 as an example of the volume indication unit is constituted by a button disposed on the lower side of the cylindrical main casing 271, for example, depending on the number of pressings of the button by the finger of the user (eg the director REN1), etc. The volume (that is, the volume) of the superimposed audio signal output from the speaker 26 is instructed. For example, when the volume is specified in three steps, the volume is low in the first step, the volume is medium in the second step, the volume is high in the third step, and the third step is continued to return to the first step. Adjustment of the volume by is repeated. The volume indicator 22 passes information indicating the instructed volume to the superimposed sound signal generator 25. Note that the distance over which the superimposed sound signal (see below) is transmitted from the sound transmitter 20 can be variably set according to the strength of the volume.

The voice ID selection unit 23 is, for example, a processor PRC2 configured using a CPU, an MPU, a DSP, or an FPGA, and the processor PRC2 is mounted on a control board (not shown) inward of the main housing 271. Ru. The voice ID selection unit 23 specifies the currently selected voice ID (for example, 10 bits) based on the information from the voice ID selection dial 21. The voice ID selection unit 23 reads data of a predetermined voice signal corresponding to the specified voice ID from the memory 24 and passes it to the superimposed voice signal generation unit 25. The voice ID selection unit 23 may pass the identified voice ID to the superimposed voice signal generation unit 25. In this case, the superimposed sound signal generation unit 25 reads out and acquires data of a predetermined sound signal corresponding to the sound ID passed from the sound ID selection unit 23 from the memory 24.

The memory 24 is configured using, for example, a RAM and a ROM, and temporarily holds programs and data required to execute the operation of the voice transmitter 20, and further, data or information generated during the operation. The RAM is, for example, a work memory used when the voice transmitter 20 operates. The ROM stores and holds, for example, a program and data for controlling the audio transmitter 20 in advance. Further, the memory 24 registers and holds the voice ID and data of a predetermined voice signal corresponding to the voice ID, which are provided in advance from the voice management server 10.

The superimposed audio signal generation unit 25 is, for example, a processor PRC2 configured using a CPU, an MPU, a DSP, or an FPGA, and the processor PRC2 is mounted on a control substrate (not shown) inward of the main housing 271. Be done. The superimposed sound signal generation unit 25 as an example of a generation unit generates a superimposed sound signal in which the sound ID passed from the sound ID selection unit 23 or obtained by itself is superimposed on a predetermined sound signal corresponding to the sound ID. When the superimposed audio signal generation unit 25 acquires the pressing signal from the trigger button 28, the superimposed audio signal generated is audio-outputted from the speaker 26 each time of acquisition.

Here, when superimposing audio signal generation unit 25 superimposes the audio ID on the audio signal, the audio signal of the frequency (for example, 20 kHz) band of the maximum value of the audible band (for example, 20 Hz to 20 kHz) of human among the audio signals. The superimposed voice signal is generated by superimposing the voice ID. As a result, in a crowded environment such as a concert hall, for example, it becomes difficult for a spectator who holds each voice receiver 30 to hear a signal in the frequency band of the maximum value of the audible band due to the influence of ambient noise and the like. Further, the signal of the frequency band of the maximum value in the human audible band is a signal of a band which can be heard or difficult by a person, and the voice ID is information of about 10 bits at most. Therefore, even if the environment is not crowded, it can be assumed that the superimposed audio signal can not be considered to give a sense of discomfort to human hearing. As a result, the audio transmitter 20 can effectively transmit the superimposed audio signal to each audio receiver 30 without giving an auditory sense of discomfort to each spectator even though the superimposed audio signal is transmitted.

The speaker 26 is disposed, for example, in the main case 271 inward, and outputs a voice of the superimposed audio signal generated by the superimposed audio signal generation unit 25.

The directivity changing unit 27 changes the directivity at the time of transmission of the superimposed audio signal output from the speaker 26 to the audio receiver 30. The directivity changing unit 27 can widen or narrow the range in which the superimposed sound signal is transmitted from the sound transmitter 20. In other words, as an example of the directivity holding unit, the directivity changing unit 27 can give directivity to the superimposed sound signal output from the speaker 26 at the time of transmission to the sound receiver 30.

Specifically, the directivity changing unit 27 is configured by using a main housing 271 in which the speaker 26 is inward, and a sub housing 272 connected to the main housing 271 in the front-rear direction. That is, the audio transmitter 20 according to each embodiment changes the directivity when transmitting the superimposed audio signal according to the physical structure of the main case 271 and the sub case 272 which constitute the transmitter main body BDY1. .

Here, in order to simplify the description of FIG. 2 and FIGS. 3A to 3F, the main housing 271 and the sub housing 272 have, for example, a cylindrical shape. However, both the main housing 271 and the sub housing 272 may not have a cylindrical shape, and may have, for example, a rectangular shape whose cross section perpendicular to the central axis of the cylinder is a rectangle.

As shown in FIG. 2, the inner diameter of the main housing 271 is larger than the inner diameter of the sub housing 272. Further, the sub case 272 has a length k0 which is a constant value in the front-rear direction of the main case 271 (in other words, the direction of the central axis of the sub case 272. The same applies hereinafter). Therefore, the audio transmitter 20 having the transmitter main body BDY1 shown in FIG. 2 can output the superimposed audio signal diffused at the propagation angle θ0 corresponding to the length k0 of the sub housing 272.

Further, as shown in FIGS. 3A, 3B, and 3C, the sub housing 272 is configured by an expansion and contraction mechanism SY1 capable of holding different states in which the length in the front-rear direction of the main housing 271 described above is expandable. May be The extension and contraction mechanism SY1 may be configured using, for example, a resin tube having flexibility and capable of holding an expanded and contracted state.

For example, as shown in FIG. 3A, the sub-casing 272 is configured by a stretching mechanism SY1 that stretches to a length k1 smaller than the length k0 in the front-rear direction of the sub-casing 272 shown in FIG. (K1 <k0). As a result, the voice transmitter 20 shown in FIG. 3A can voice-output the superimposed voice signal at a propagation angle θ1 that is wider than the propagation angle θ0, as compared to the voice transmitter 20 shown in FIG. The transmission range of the superimposed audio signal can be adjusted widely compared to the expanded and contracted state shown.

For example, as shown in FIG. 3B, the sub case 272 expands and contracts to a length k2 substantially equal to the length k0 in the front-rear direction of the sub case 272 shown in FIG. Configured (k22k0). As a result, the audio transmitter 20 shown in FIG. 3B can output the audio signal superimposed at a propagation angle θ2 equivalent to that of the audio transmitter 20 shown in FIG. 2, and compared with the expanded state shown in FIG. The transmission range can be adjusted to be narrowed to a certain extent, and furthermore, the transmission range of the superimposed audio signal can be adjusted to a certain degree of wide angle as compared with the expanded state shown in FIG. 3C.

For example, as shown in FIG. 3C, the sub-casing 272 is configured by a stretching mechanism SY1 that stretches to a length k3 larger than the length k0 in the front-rear direction of the sub-casing 272 shown in FIG. (K3> k0). Thus, the voice transmitter 20 shown in FIG. 3C can voice output of the superimposed voice signal at a propagation angle θ3 narrower than the propagation angle θ0 as compared to the voice transmitter 20 shown in FIG. 2, and the expansion and contraction shown in FIG. 3B Adjustment can be made to further narrow the transmission range of the superimposed sound signal as compared to the state.

Further, as shown in FIGS. 3D, 3E, and 3F, the sub-casing 272 starts from the connecting portion with the main casing 271 (the same applies to the following), and compared with the diameter of the main casing 271 described above. It has the diameter which becomes the same or large toward the tip side (front side shown in FIG. 2) where the superimposed voice signal is voice-outputted, and is constituted by the opening adjustment portion KY1 capable of holding the state of opening toward the tip side It is also good. The opening adjustment portion KY1 may be configured using, for example, a resin member having flexibility and capable of holding an expanded or contracted state.

For example, as shown in FIG. 3D, in order to obtain a propagation angle θ4 that is considerably wider than the propagation angle θ0 formed by the sub-housing 272 shown in FIG. The opening adjustment portion KY1 holds the state of opening from the starting point (see above) to the tip side (θ4> θ0). Thus, the voice transmitter 20 shown in FIG. 3D can voice output of the superimposed voice signal at a propagation angle θ 4 that is considerably wider than the propagation angle θ 0 as compared to the voice transmitter 20 shown in FIG. Compared to the open state shown in 3F, the transmission range of the superimposed audio signal can be adjusted considerably widely.

For example, as shown in FIG. 3E, in order to obtain a propagation angle θ5 slightly wider than the propagation angle θ0 formed by the sub-housing 272 shown in FIG. 2, the sub-housing 272 of the sub-housing 272 shown in FIG. It is comprised by the opening adjustment part KY1 which hold | maintained the state opened toward the front end side from the origin (refer above) ((theta) 5> (theta) 0). Thus, the voice transmitter 20 shown in FIG. 3E can voice-output the superimposed voice signal at a propagation angle θ5 slightly wider than the propagation angle θ0 as compared to the voice transmitter 20 shown in FIG. 2, and the aperture shown in FIG. The transmission range of the superimposed audio signal can be adjusted a little wider compared to the state, and furthermore, the transmission range of the superimposed audio signal can be adjusted slightly narrowed compared to the open state shown in FIG. 3D.

For example, as shown in FIG. 3F, in order to obtain a propagation angle θ 6 substantially equal to the propagation angle θ 0 formed by the sub-housing 272 shown in FIG. 2, the sub-housing 272 starts the sub-casing 272 shown in FIG. It is comprised by the opening adjustment part KY1 which hold | maintained the state which is not opened toward a front end side from (refer above) ((theta) 6 ≒ θ 0). Thus, the voice transmitter 20 shown in FIG. 3F can voice output of the superimposed voice signal at a propagation angle θ6 substantially equal to the propagation angle θ0 as compared to the voice transmitter 20 shown in FIG. The transmission range of the superimposed sound signal can be adjusted to be considerably narrowed compared to the open state shown.

The trigger button 28 as an example of the output instruction unit is provided in the holding unit HLD1 held by the hand of the user (for example, the performer REN1), and instructs output of the superimposed sound signal. Specifically, the trigger button 28 is configured using, for example, a button that can be pressed by the finger of the user (for example, the director REN 1), and when it is detected that the button is pressed, a press signal indicating that is superimposed Pass it to the audio signal generator 25.

The communication unit 31 has a role as a communication interface regarding communication with the voice management server 10. When the information of the control method sent together with the voice ID is acquired from the voice management server 10, the voice ID and the control method are The information is passed to the control unit 33. Further, when acquiring the acquisition request including the voice ID from the control unit 33, the communication unit 31 sends the acquisition request to the voice management server 10.

The microphone 32 as an example of the sound collection unit collects the superimposed sound signal in which the sound ID is superimposed on the sound signal corresponding to the sound ID. The microphone 32 passes the data of the collected superimposed voice signal to the voice ID recognition unit 34.

The control unit 33 is a processor PRC3 configured using, for example, a CPU, an MPU, a DSP, or an FPGA. The control unit 33 functions as a controller that controls the operation of the audio receiver 30, and performs control processing to generally control the operation of each unit of the audio receiver 30, and input of data with each unit of the audio receiver 30. It performs output processing, data calculation (calculation) processing, and data storage processing. The control unit 33 operates in accordance with the program and data stored in the memory 35. The control unit 33 may use the memory 35 at the time of operation, and temporarily store data or information generated or acquired by the control unit 33 in the memory 35.

When acquiring the voice ID from the voice ID recognition unit 34, the control unit 33 generates an acquisition request for the control method associated with the voice ID including the voice ID. The control unit 33 passes the generated acquisition request to the communication unit 31, and requests the information on the control method corresponding to the voice ID from the voice management server 10 via the communication unit 31. When the control unit 33 acquires information on the control method sent from the voice management server 10 via the communication unit 31 (specifically, information on the control method sent together with the voice ID), the acquired control method The above information is specified as the information of the control method corresponding to the voice ID passed from the voice ID recognition unit 34. The control unit 33 temporarily stores the information of the control information in the memory 35 in association with the voice ID, and generates an instruction to execute notification (see below) according to the specified control method, Pass to (see below).

Here, the control method is one voice ID and one-to-one correspondence, for example, in a crowded environment where many spectators gather such as a concert hall, the presentation effect in the voice receiver 30 associated with the voice ID (described above Reference) is information that defines various notification methods for creating a reference. The method of notification is, for example, a combination of at least one or more of display on display 36, lighting or blinking of light 37, vibration of vibrator 38, and output of sound from speaker 39. The description of the control method is the same as in the embodiments described below.

The voice ID recognition unit 34 as an example of the recognition unit is a processor PRC1 configured using, for example, a CPU, an MPU, a DSP, or an FPGA. When the voice ID recognition unit 34 acquires the superimposed voice signal from the microphone 32, the voice ID recognition unit 34 extracts a voice ID (for example, 10 bits) which is a bit pattern superimposed on the superimposed voice signal and passes it to the control unit 33.

The memory 35 is configured using, for example, a RAM and a ROM, and temporarily holds programs and data required to execute the operation of the audio receiver 30, and further, data or information generated during the operation. The RAM is, for example, a work memory used when the voice receiver 30 operates. The ROM stores and holds, for example, a program and data for controlling the voice receiver 30 in advance. Further, the memory 35 may temporarily hold the voice ID and the information of the control method corresponding to the voice ID in association with each other.

The display 36 as an example of the notification unit is configured using, for example, an LCD (Liquid Crystal Display) or an organic EL (Electroluminescence), and a control method corresponding to the execution instruction based on the notification execution instruction from the control unit 33. Display various data or information according to The display 36 may be configured as a touch panel capable of detecting an input operation of the user of the audio receiver 30.

Next, in the voice transmission system 100 according to the present embodiment, the voice transmitter 20 transmits to a portion of the voice receivers 30 selected by the director REN 1 among all the voice receivers 30 in the concert hall. The outline of the operation in which the superimposed audio signal is transmitted will be described with reference to FIG. 4, FIG. 5, and FIG. FIG. 4 is an explanatory view showing a first use case of the voice transmission system 100 according to the first embodiment. FIG. 5 is an explanatory view showing a second use case of the voice transmission system 100 according to the first embodiment. FIG. 6 is an explanatory diagram of a second use case of the voice transmission system 100 according to the first embodiment.

In FIG. 4, at a certain time, a director REN1 (for example, an artist) who is on the stage of the concert hall holds the audio transmitter 20 by hand, and the audience seat PLT1 on the platform is shielded from the stage by the wall GT1 serving as a threshold. The superimposed audio signal is transmitted to any one (for example, the audience AUD1) among the audiences AUD1, AUD2 and AUD3 (for example, a total of three people) who are holding the audio receiver 30 possessed. A voice ID is superimposed on the voice signal corresponding to the voice ID in the superimposed voice signal.

When the audio receiver 30 of the audience AUD1 picks up the superimposed audio signal from the audio transmitter 20, the audio receiver 30 identifies a control method corresponding to the audio ID included in the superimposed audio signal, and light according to the identified control method. Performs various outputs (notifications) using noise, vibration, etc. to create a rendering effect.

In FIG. 5, at a certain time T = t1, the director REN1 (for example, an artist) who is on the stage of the concert hall holds the audio transmitter 20 by hand and holds it in the audience seat provided at a position shielded from the stage. Toward the audience AUD11, AUD12, AUD13, AUD14, AUD15, AUD16, AUD17, AUD18, AUD19, AUD20 (for example, a total of 10 people) who are shaking the audio receiver 30 to three people (for example, the audience AUD17 to AUD19) And transmit the superimposed audio signal. A voice ID is superimposed on the voice signal corresponding to the voice ID in the superimposed voice signal.

When the audio receivers 30 of the audience AUD17 to AUD19 pick up the superimposed audio signal from the audio transmitter 20, they identify the control method corresponding to the same audio ID included in the superimposed audio signal, and are identified. According to the above control method, various outputs (notifications) using light, sound, vibration and the like are performed, and all three units produce the same effect. In other words, at time T = t1, the audio receivers 30 of the other audiences AUD11 to AUD16 and AUD20 can not pick up the superimposed audio signals, and thus can not execute the notification process performed by the audio receivers 30 for the audiences AUD17 to AUD19. . That is, the voice receiver 30 that produces the rendering effect corresponding to the voice ID is selected by the renderer REN 1 that operates the voice transmitter 20 that transmits the superimposed voice signal.

Similarly, in FIG. 6, at time T = t2 after time t1, the director REN1 holds the audio transmitter 20 by hand while the direction of the body is a little (in other words, the superimposed audio signal of the audio transmitter 20 is Similarly, the superimposed audio signal is transmitted to any three of the 10 audiences AUD11 to AUD20 (for example, the audience AUD14 to AUD16) by changing the output direction. In this superimposed voice signal, the same or a different voice ID as that in FIG. 5 is superimposed on the voice signal corresponding to the voice ID.

When the audio receivers 30 of the audience AUD14 to AUD16 pick up the superimposed audio signal from the audio transmitter 20, they identify the control method corresponding to the same audio ID included in the superimposed audio signal, and are identified. According to the above control method, various outputs (notifications) using light, sound, vibration and the like are performed, and all three units produce the same effect. In other words, at time T = t2, the audio receiver 30 of the other audiences AUD11 to AUD13 and AUD17 to AUD20 can not pick up the superimposed audio signal, so the notification process performed by the audio receiver 30 of the audience AUD14 to AUD16 is It can not be performed. That is, the voice receiver 30 that produces the rendering effect corresponding to the voice ID is selected by the renderer REN 1 that operates the voice transmitter 20 that transmits the superimposed voice signal.

4 to 6 illustrate an example in which the superimposed audio signal is transmitted from the audio transmitter 20 to a part of the audio receivers 30, for example, from the performer REN 1 (that is, from the audio transmitter 20) When all the audio receivers 30 are uniformly spaced sufficiently apart, even if all the audio receivers 30 pick up the superimposed audio signal and perform the same notification to produce a rendering effect. Good.

FIG. 7A is an explanatory diagram of a range of the audio receiver 30z in which an audio ID is received by wireless communication (electromagnetic wave) as a comparative example. FIG. 7B is an explanatory diagram of a range of the audio receiver 30 in which the audio ID is detected by audio transmission (radio wave) as the first embodiment.

As shown in FIG. 7A, it is assumed that the voice ID according to the present embodiment is transmitted from the voice transmitter 20z to the voice receiver 30z using wireless communication (electromagnetic wave). When the signal on which the voice ID is superimposed is transmitted from the voice transmitter 20z to the voice receiver 30z by the electromagnetic wave, the signal is received by all the voice receivers 30z, and some of them are limited. It is difficult to make it receivable by the voice receiver 30z of the other range. Therefore, for example, in a concert hall, it is difficult to produce the rendering effect with only a part of the limited voice receivers 30z selected from the performer holding the voice transmitter 20z, and the output accuracy of the rendering effect is insufficient Can be considered.

Further, when transmitting and receiving an audio ID using wireless communication, it becomes necessary to install a special antenna in the audio transmitter 20, and a receiving antenna for receiving a signal from the antenna is used as the audio receiver 30. In addition, the problem that the cost increase of the voice receiver 30 can not be avoided arises separately. In addition, when using wireless communication, it is technically important to determine in advance a group of some audio receivers 30 capable of receiving the signal from the audio transmitter 20, and individually transmit the audio ID only to that group. Although it is possible, for example, it is not easy to switch the directivity at the time of transmission of the superimposed sound signal instantaneously as the director REN 1 rotates the body.

Moreover, although illustration is abbreviate | omitted in FIG. 7A, for example, suppose that audio | voice ID which concerns on this Embodiment is transmitted using light (optical communication). Light has a characteristic that the straightness of propagation is higher than that of a sound wave and that the sound wave is less likely to be diffracted. For this reason, when the signal on which the voice ID is superimposed is transmitted from the voice transmitter 20z to the voice receiver 30z by the electromagnetic wave, the signal is received by only one voice receiver 30z, It is difficult to make it receivable by some limited range voice receiver 30z. Therefore, for example, in a concert hall, it is difficult to produce the rendering effect with only a part of the limited voice receivers 30z selected from the performer holding the voice transmitter 20z, and the output accuracy of the rendering effect is insufficient Can be considered.

On the other hand, as shown in FIG. 7B, it is assumed that the superimposed voice signal on which the voice ID according to the present embodiment is superimposed is transmitted from the voice transmitter 20 to the voice receiver 30 using a sound wave. View. The sound wave diffuses in the same manner as the light, but it has a characteristic that the straightness of the traveling is not high compared to the light, and the light wave is more easily diffracted than the light. Therefore, when the superimposed audio signal on which the voice ID is superimposed is transmitted from the voice transmitter 20 toward the voice receiver 30 by the sound wave, it can be received by the voice receiver 30 of a limited range. It becomes possible to Thereby, for example, in a concert hall, it becomes possible to produce a stage effect by only a part of the limited audio receivers 30 selected from the performer REN 1 holding the audio transmitter 20, and the concert hall is powerful It is possible to exhibit the effect of output accuracy so as to considerably boost the atmosphere of.

Next, the operation procedure of the voice transmission system 100 according to the present embodiment will be described with reference to FIG. FIG. 8 is a sequence diagram showing an example of an operation procedure of the voice transfer system 100 according to the first embodiment.

In FIG. 8, the voice management server 10 associates a voice ID, which is identification information of a voice, with data of a predetermined voice signal corresponding to the voice ID, and registers and stores in the voice ID memory 14 (S1). The voice management server 10 associates the voice ID with the information of the control method corresponding to the voice ID, and registers and stores the voice ID in the control method memory 15 (S2).

The voice management server 10 reads out the voice ID and the data of the default voice signal corresponding to the voice ID from the voice ID memory 14 and outputs the data to the voice transmitter 20 (S3). In step S3, in a state where the voice management server 10 and the voice transmitter 20 are physically connected by a wired cable such as a USB (Universal Serial Bus) cable, for example, the voice ID and the voice signal corresponding to the voice ID Data is passed from the communication unit 11 of the voice management server 10 to the voice transmitter 20.

In addition, the method of delivery of the voice ID and the data of the voice signal corresponding to the voice ID between the voice management server 10 and the voice transmitter 20 in step S3 is limited to the method performed by the connection of the USB cable described above. For example, a voice ID and data of a voice signal corresponding to the voice ID are temporarily copied from the voice management server 10 to an external storage medium (for example, a semiconductor memory such as a USB memory), and the external storage medium is It may be copied and delivered to the audio transmitter 20 via the interface.

The voice transmitter 20 acquires the voice ID and the data of the voice signal corresponding to the voice ID passed from the voice management server 10 in step S3, and the voice ID and the data of the voice signal corresponding to the voice ID Are registered in the memory 24 and stored (S4). The audio transmitter 20 generates a superimposed audio signal in which one of the audio IDs is selected by, for example, the operation of the performer REN 1 and the selected audio ID is superimposed on a predetermined audio signal corresponding to the audio ID. (S5). The voice transmitter 20 voice-outputs the generated superimposed voice signal from the speaker 26 (S5). The superimposed sound signal (in other words, sound wave) propagates in the space where both the sound transmitter 20 and the sound receiver 30 exist, and is transmitted to the sound receiver 30.

The voice receiver 30 picks up the superimposed voice signal, which is voice-outputted in step S5, with the microphone 32 (S6). The voice receiver 30 recognizes the voice ID superimposed on the collected superimposed voice signal (S7), and in order to inquire the voice management server 10 about the control method corresponding to the recognized voice ID, the voice ID And a request for acquisition of a control method including the above is sent to the voice management server 10 (S7).

When the voice management server 10 receives the acquisition request sent from the voice receiver 30 in step S7, the voice management server 10 extracts the voice ID included in the acquisition request (S8). The voice management server 10 reads out and acquires information on the control method corresponding to the extracted voice ID from the control method memory 15 (S8). As a response to the acquisition request received in step S8, the voice management server 10 transmits the information of the control method acquired in step S8 to the voice receiver 30 in association with the corresponding voice ID (S9).

The voice receiver 30 receives the voice ID sent from the voice management server 10 in step S9 and the information of the control method corresponding to the voice ID (S10). The voice receiver 30 outputs an instruction to execute various notices (outputs) according to the received information of the control method to a notifying unit (for example, the display 36, the light 37, the vibrator 38, the speaker 39) to display Notification is performed using at least one of the display by 36, the lighting or blinking by the light 37, the vibration by the vibrator 38, and the audio output by the speaker 39 (S11).

As described above, in the audio transmission system 100 according to the first embodiment, the audio transmitter 20 transmits an audio signal to at least one audio receiver 30. The voice transmitter 20 generates a superimposed voice signal in which a voice ID, which is identification information of voice, is superimposed on a voice signal corresponding to the voice ID, and outputs the generated superimposed voice signal from the speaker 26. Further, the audio transmitter 20 changes the directivity at the time of transmission of the superimposed audio signal output from the speaker 26 to the audio receiver 30.

Thereby, in the voice transmission system 100, even when the plurality of voice receivers 30 exist at a position where the voice to be transmitted can be detected, the voice transmitter 20 can flexibly change the transmission destination of the voice while changing it. . In addition, the voice receiver 30 that has detected the voice transmitted from the voice transmitter 20 exudes an effect unique to the voice ID corresponding to the voice, thereby enhancing the entertainment characteristics that boosted the surrounding atmosphere. Can be

Further, for example, when an audio ID is designated by the operation of the performer REN 1, the audio transmitter 20 acquires data of an audio signal corresponding to the instructed audio ID from the memory 24. The voice transmitter 20 generates a superimposed voice signal in which the instructed voice ID is superimposed on the obtained voice signal. As a result, the audio transmitter 20 can easily generate a superimposed audio signal in which the audio ID instructed by the director REN1 is superimposed on a predetermined audio signal specific to the audio ID.

Further, when the sound volume of the superimposed sound signal is instructed by, for example, the operation of the performer REN 1, the sound transmitter 20 generates a superimposed sound signal according to the instructed sound volume. Thus, the audio transmitter 20 can transmit the superimposed sound signal output from the speaker 26 at a transmittable distance (in other words, the audio receiver 30 capable of collecting the superimposed sound signal) according to the volume instructed by the director REN 1. Position) can be set flexibly.

Further, in the audio transmitter 20, the directivity changing unit 27 is configured using a main housing 271 that at least includes the speaker 26, and a sub housing 272 connected to the main housing 271. As a result, the audio transmitter 20 can set the directivity at the time of transmission of the superimposed audio signal output from the speaker 26 inward to the main housing 271 to, for example, the size of the main housing 271 and the sub housing 272. It can be selected variably from the relationship.

Further, in the audio transmitter 20, the sub housing 272 is configured by the extension and contraction mechanism SY1 whose length in the direction of the central axis of the main housing 271 is variable. Thereby, the voice transmitter 20 is the same as or different from the propagation angle θ0 as compared with the voice transmitter 20 having the sub casing 272 in which the length in the direction of the central axis of the main casing 271 is fixed (see FIG. 2) The superimposed voice signal can be output as voice at a propagation angle (specifically, propagation angles θ1, θ2, θ3), and the transmission range of the superimposed voice signal can be made wide-angle, narrowed, or flexibly adjusted.

Further, in the audio transmitter 20, the sub housing 272 is configured by the opening adjusting portion KY1 having a diameter that is the same as or larger than the diameter of the main housing 271 toward the tip side where the superimposed audio signal is output. Ru. Thereby, the audio transmitter 20 has the same or different propagation angle as the propagation angle θ 0 as compared with the audio transmitter 20 in which the opening state is not formed from the start point of the sub housing 272 toward the tip side (see FIG. 2) Specifically, the superimposed voice signal can be voice-outputted at the propagation angles θ4, θ5, θ6), and the transmission range of the superimposed voice signal can be made wide, narrow, or flexibly adjusted.

Further, the audio transmitter 20 is connected to the main housing 271, held by the hand of the user (for example, the effecter REN1), and instructs the output of the superimposed audio signal by the trigger button 28 provided on the holding unit HLD1. The speaker 26 outputs the superimposed sound signal in response to the instruction of the output of the superimposed sound signal to the trigger button 28. As a result, the performer REN 1 can output the superimposed audio signal from the audio transmitter 20 at his / her favorite timing, so that the audio transmitter 20 can be operated easily and simply.

Further, the voice receiver 30 picks up the superimposed voice signal in which the voice ID is superimposed on the voice signal corresponding to the voice ID by the microphone 32, and based on the picked up superimposed voice signal, the voice signal is superimposed on the superimposed voice signal. Recognize the superimposed voice ID. The voice receiver 30 specifies a notification method indicating the rendering effect corresponding to the recognized voice ID, and executes notification according to the specified notification method. Thereby, if the audio receiver 30 is located at a position where it can pick up the superimposed audio signal transmitted from the audio transmitter 20, a unique (unique) control method associated with the audio ID included in the superimposed audio signal. It is possible to execute various types of notification according to the above, and it is possible to effectively produce an entertainment effect that excites the surrounding atmosphere by producing a unique effect.

Further, the voice receiver 30 transmits an acquisition request for a notification method corresponding to the recognized voice ID to the external voice management server 10, and receives the notification method sent from the voice management server 10 based on the acquisition request. Do. The voice receiver 30 outputs an instruction to execute notification according to the received notification method to a notification unit (for example, at least one of the display 36, the light 37, the vibrator 38, and the speaker 39). Thereby, even when the voice receiver 30 recognizes and stores the voice ID and the control method information corresponding to the voice ID in association with each other, the voice receiver 30 corresponds to the voice ID each time it recognizes the voice ID. Since the control method may be inquired, the data holding capacity of the memory 35 can be relatively reduced.

In addition, the voice management server 10 associates the voice ID with the data of the voice signal corresponding to the voice ID and stores the voice ID in the voice ID memory 14, and predetermined timing (for example, the voice management server 10 and the voice transmitter 20). The data of the audio signal corresponding to the audio ID is acquired from the audio ID memory 14 at the timing when the management unit 12 detects that the communication is communicably connected. Further, the voice management server 10 outputs from the communication unit 11 to the voice transmitter 20 that outputs the superimposed voice signal in which the data of the obtained voice signal is superimposed on the voice signal corresponding to the voice ID. Do. As a result, the voice management server 10 can appropriately manage and hold the voice ID and data of a predetermined voice signal specific to the voice ID, so that the voice management server 10 is suitable for an inquiry about data acquisition from the voice receiver 30. Can be sent according to.

Further, the voice management server 10 associates the voice ID with the notification method indicating the rendering effect corresponding to the voice ID, stores the result in the control method memory 15, and outputs the superimposed voice signal output from the voice transmitter 20. An acquisition request for a control method corresponding to the audio ID included in the superimposed audio signal is received from the collected audio receiver 30. The voice management server 10 obtains the control method corresponding to the voice ID from the control method memory 15 according to the acquisition request, and transmits the obtained control method to the voice receiver 30. As a result, the voice management server 10 can appropriately manage and hold the voice ID and the information of the control method for specifying the rendering effect specific to the voice ID, so that the query for data acquisition from the voice receiver 30 can be performed. Can be sent according to the appropriate.
