A karaoke maraca according to the present embodiment will be described with reference to FIGS. 1 to 5. FIG.

As shown in FIG. 1, the karaoke maracas 1 according to the present embodiment are composed of a spheroidal container C and a linear grip H. As shown in FIG. Inside the container C, ferromagnetic particles P (see FIG. 2) are sealed as a sounding body. The grip H is connected to the base end of the container C. As shown in FIG. The grip portion H is a portion that a user grips when using the maracas 1 for karaoke. When the user shakes the karaoke maracas 1 while gripping the grip H, the ferromagnetic particles P move within the container C (see the dashed arrow in FIG. 2) and collide with each other or the inner wall of the container C. pronounce by doing

As shown in FIG. 2, the karaoke maraca 1 has ferromagnetic particles P, a fixed portion F, an electromagnet E, and a controller M. As shown in FIG. In this example, the ferromagnetic particles P and the fixed part F are provided inside the container C. As shown in FIG. On the other hand, the electromagnet E and the controller M are provided inside the grip H. As shown in FIG. A power source (not shown) for supplying electric power to the electromagnet E and the control device M is also provided inside the gripping portion H. FIG.

The ferromagnetic particles P are metal particles with a diameter of about 1 mm. A large number of ferromagnetic particles P are enclosed in the container C. As shown in FIG.

The fixed portion F is a magnetizable structure made of, for example, a ferromagnetic material. The fixed part F is provided at a predetermined position inside the container C. As shown in FIG. As a specific example, the fixing portion F can be provided in the vicinity of the end (base end portion of the container C) to which the gripping portion H is connected (see FIG. 3). Alternatively, the fixing portion F can be provided near the end (the tip of the container C) opposite to the side to which the gripping portion H is connected (see FIG. 4). In the example of FIGS. 3 and 4, the fixing portion F is provided as a bowl-shaped area. The number of ferromagnetic particles P enclosed in the container C is preferably such that it can be accommodated in the bowl-shaped fixing portion F. As shown in FIG. In FIGS. 3 and 4, the description of the ferromagnetic particles P is omitted.

Electromagnet E is magnetically connected to fixed portion F. FIG. The electromagnet E is normally in an OFF state, and turns ON when energized. The ON state is a state in which the magnet functions, and the OFF state is a state in which it does not function as a magnet.

The control device M performs various controls of the maracas 1 for karaoke. As shown in FIG. 2 , the control device M according to this embodiment functions as a sound generation control section 10 .

When the sound generation control unit 10 receives from the karaoke apparatus K a singing section signal indicating that karaoke is being performed in a singing section of a certain piece of music, the sound generation control unit 10 energizes the electromagnet E to prohibit sound generation of the maracas 1 for karaoke. . Further, when the singing section signal is not received for a predetermined period of time, the sound control unit 10 stops driving the electromagnet E, thereby permitting the karaoke maracas 1 to sound. Any value can be set in advance for the predetermined period.

When the sound generation control section 10 energizes the electromagnet E, the electromagnet E is turned on. The fixed portion F is magnetized by the magnetic force generated by the electromagnet E. As shown in FIG. The ferromagnetic particles P in the container C are fixed to the fixed portion F by magnetization of the fixed portion F. As shown in FIG.

Even if the karaoke maracas 1 are shaken in such a state, it is difficult for the ferromagnetic particles P to move within the container C. Therefore, the sound of the karaoke maracas 1 can be prohibited.

On the other hand, when the sound generation control section 10 stops energizing the electromagnet E, the electromagnet E is turned off. In this case, since the fixed portion F is not magnetized, the ferromagnetic particles P can move within the container C. Therefore, when the karaoke maracas 1 are shaken, a sound can be produced.

Next, specific operations of the karaoke maracas 1 according to the present embodiment will be described with reference to FIG. In this example, the karaoke machine K and the karaoke maracas 1 are paired in advance. Also, the karaoke machine K and the karaoke maracas 1 can communicate using a general short-range wireless communication technology.

Here, it is assumed that singer X uses karaoke device K to sing song Y in karaoke. In this case, the karaoke machine K identifies the singing section uttered by the singer from the music data of the musical piece Y and other sections (non-singing section). The karaoke device K transmits a singing segment signal to the karaoke maracas 1 during karaoke performance in the singing segment.

The sound generation control unit 10 receives the singing interval signal transmitted from the karaoke machine K (reception of the singing interval signal; step 10).

The sound control unit 10 energizes the electromagnet E to prohibit the sound of the karaoke maracas 1 (prohibit sound of the maracas, step 11). Therefore, even if the singer X uses the karaoke maracas 1 while singing karaoke, no sound is produced.

After that, it is assumed that the singing section ends. In this case, the karaoke machine K stops transmitting the singing segment signal.

If no singing section signal is received for a predetermined period of time (Y in step 12), the sounding control section 10 stops energizing the electromagnet E, thereby permitting the karaoke maracas 1 to sound (the maracas Allow pronunciation, step 13).

As described above, the karaoke maracas 1 according to the present embodiment generate sound when the ferromagnetic particles P enclosed in the container C collide with each other or the inner wall of the container C. As shown in FIG. The karaoke maracas 1 are provided at a predetermined position in a container C, and are supplied from a fixed part F that can be magnetized, an electromagnet E magnetically connected to the fixed part F, and a karaoke device K for a singing section of a certain piece of music. and a sounding control section 10 for inhibiting sounding by energizing the electromagnet E when a singing interval signal indicating that the music is being played is received.

According to such karaoke maracas 1, sounding is prohibited during karaoke performance in the singing section. Therefore, the singer can sing karaoke without worrying about the sound of the maracas 1 for karaoke. That is, according to the maracas 1 for karaoke according to the present embodiment, it is possible to prohibit use that interferes with karaoke singing.

In addition, the karaoke maracas 1 according to the present embodiment have a gripping portion H that is connected to the container C and gripped by the user, and the fixing portion F is provided near the end on the side to which the gripping portion H is connected. be able to. By providing the fixing portion F at such a position, the structure of the karaoke maracas 1 can be simplified.

Alternatively, the karaoke maracas 1 according to this embodiment have a grip portion H that is connected to the container C and gripped by the user, and the fixed portion F has an end opposite to the side to which the grip portion H is connected. It can be provided in the vicinity of the part. By providing the fixed portion F at such a position, the silencing effect can be enhanced.

Further, when the singing section signal is not received for a predetermined period of time, the sounding control unit 10 stops energizing the electromagnet E, thereby permitting the sounding body to sound. If the singing section signal is not received for a predetermined period of time, it means that karaoke singing is not being performed (or karaoke performance itself is not being performed). In such a case, the ferromagnetic particles P can be moved within the container C by stopping the energization of the electromagnet E. FIG. Therefore, it is possible to sound the maracas 1 for karaoke.

<Others>
It should be noted that the shape of the container C and the gripping portion H, the internal arrangement of the karaoke maracas 1, and the like in the above embodiment are not limited to the above example.

For example, container C may be spherical. Also, the electromagnet E may be provided in the container C. In this case, since the distance between the electromagnet E and the fixed portion F is reduced, the magnetic force generated by the electromagnet E can be transmitted to the fixed portion F more reliably. Also, the fixing portion F may be provided on both the distal end side and the proximal end portion side of the container C (a shape having both the fixing portion F shown in FIG. 3 and the fixing portion F shown in FIG. 4 may be provided). . In this case, the electromagnet E can also be provided on the tip end side and the base end side of the container C. By providing a plurality of fixing portions F in this way, it becomes possible to more reliably catch the ferromagnetic particles P moving in the container C and to muffle the noise. Alternatively, the fixing portion F may be provided throughout the container C. As shown in FIG.

Also, the karaoke machine K may transmit the start signal and the end signal of the singing section instead of transmitting the singing section signal. When the start signal is received, the sound generation control section 10 energizes the electromagnet E to prohibit the sound generation of the maracas 1 for karaoke. On the other hand, when the end signal is received, the sound control unit 10 stops energizing the electromagnet E, thereby permitting the karaoke maracas 1 to sound. According to such a configuration, it is possible to use the karaoke maracas 1 in the non-singing section of a certain piece of music, so that the karaoke singing scene can be further livened up without disturbing the karaoke singing.

Also, the karaoke maracas 1 may have a demagnetization function. As a result, even if the ferromagnetic particles P and the fixed portion F are magnetized due to long-term use, they can be demagnetized. A known technique can be used for the demagnetization function. For example, the controller M causes the electromagnet E to generate an alternating magnetic field with alternating current. Then, in a state in which the magnetized ferromagnetic particles P and the fixed portion F are placed in the alternating magnetic field, the control device M controls the current to gradually approach 0, so that the ferromagnetic particles P and The fixed part F can be demagnetized.

The above embodiments are presented as examples and are not intended to limit the scope of the invention. The above configurations can be implemented in combination as appropriate, and various omissions, replacements, and modifications can be made without departing from the scope of the invention. The above-described embodiments and modifications thereof are included in the invention described in the claims and their equivalents, as well as being included in the scope and gist of the invention.
