Description

  The present invention relates to a microphone for use in karaoke or the like and a karaoke system using the same, and in particular, according to the distance between the mouth and the microphone unit which are different depending on the singer's preference, suitable voice pressure The present invention relates to a microphone with a microphone unit position adjusting mechanism and a karaoke system including the same.

  A microphone is used as an interface for amplifying and outputting a human voice with an amplifier. Such a microphone is roughly divided into a dynamic microphone and a condenser microphone. Dynamic microphones are suitable for karaoke singing and use the principle that when a coil is vibrated in the vicinity of a permanent magnet, the magnetic flux in the coil changes and an electromotive force is generated in the coil (electromagnetic induction) It is. The microphone unit of the dynamic microphone has a structure in which a coil is fixed to a plastic diaphragm (diaphragm) formed in a dome shape, and this diaphragm receives a sound wave to vibrate, and a voice signal is obtained by moving the coil in a magnetic field. ing.

  Capacitor microphones are suitable for recording professional singers, and the principle that a change in capacitance can be taken out as a change in voltage when a DC voltage is applied across the electrodes of the capacitor via a high resistance. Is used. That is, in the capacitor microphone, the change in the capacitance proportional to the audio signal occurs due to the change in the distance between the electrodes according to the vibration. The microphone unit of the capacitor microphone has a structure in which one of capacitors formed by bringing two parallel metal plates close to each other is replaced with a diaphragm (a plastic film or a metal thin film with a deposited metal attached thereto).

  By the way, it is known that the sound quality of the microphone changes depending on the use situation, how the user holds it, and the like. For example, since the acoustic resistance differs between when performing speech using the same microphone and when performing singing, it is necessary to adjust the low frequency characteristics. For this reason, in the conventional microphone, a series circuit consisting of a choke coil and a switch is connected in parallel to the electrical output circuit of the microphone unit, and the choke coil is connected in parallel to the microphone unit by switching the switch. Alternatively, the low frequency characteristics are changed by disconnection. In addition, a microphone that can adjust low-frequency characteristics has been proposed in order to suppress impedance variation and reduce costs (see Patent Document 1).

  The microphone described in Patent Document 1 is provided with a rotary shutter mechanism with a window between the back air chamber of the microphone unit and the outside, and the degree of communication between the back air chamber and the outside is determined by the opening of the rotary shutter mechanism. Or a plurality of back air chambers of the microphone unit, a valve mechanism for changing the degree of communication between the back air chambers is provided between the plurality of back air chambers, and the opening degree of the valve mechanism is changed. Therefore, the acoustic resistance is adjusted.

  By the way, now that the karaoke system has become widespread, not only professional singers but also ordinary people can easily sing. And if you become familiar with singing techniques, you will also use your nerves to use the microphone. For example, the effect of singing is further emphasized by slightly changing the distance from the singer's mouth to the windshield of the microphone according to the karaoke piece to be sung. In other words, the sound intensity (voice pressure) from an omnidirectional point sound source is inversely proportional to the square of the distance from the sound source, so from the singer's mouth to the windshield, strictly speaking, from the mouth to the microphone unit diaphragm. The distance (microphone position) affects the voice pressure input to the microphone and has a subtle effect on the sound output. In addition, the microphone has a microphone position (so-called microphone position that can absorb sound) that is optimal for singing depending on various characteristics such as the structure and parts used. Therefore, a singer who has high microphone operation technology adjusts the distance from the mouth to the diaphragm of the microphone unit during the singing or for each piece of music based on the experience in order to ensure a suitable voice pressure. .

  However, when singing with a microphone, the position that is easy to hold varies from person to person, and in the case of a singer who does not have high microphone operation skills, it is easy to hold without adjusting the position of the microphone. Singing while holding the microphone in position, it is difficult to maintain the optimal microphone position for singing. In other words, in the case of a singer who does not have the technology to fine-tune the microphone position, the singer sings with the microphone at the position where the singer is most likely to sing and cannot clearly hear his / her singing voice. In some cases, it was not possible to fully enjoy the joy of singing.

  The present invention has been proposed in view of the above-described circumstances, and even a user who is not familiar with the microphone operation technology can secure a suitable voice pressure while holding the microphone in a position that the user can easily hold.

And a moving means for moving the microphone unit to an arbitrary position. The longitudinal direction of the grip part means that when the microphone user holds the microphone by holding the grip part and keeps the distance between the tip part (for example, windshield) and the mouth constant, the mouth and the microphone unit ( The direction in which the distance to the diaphragm is closer or farther away.

  In the microphone having such a configuration, the microphone unit is supported by the supporting means so as to be movable along the longitudinal direction of the grip. Then, the microphone unit can be moved to an arbitrary position by the moving means.

  The support means includes, for example, a mechanism that inserts and supports a microphone unit inside a cylindrical grip portion. Further, the moving means is formed of, for example, screw portions that are provided on the inner peripheral surface of the cylindrical grip portion and the outer peripheral surface of the microphone unit and mesh with each other. Further, the moving means may have the function of the supporting means.

  The karaoke system of the present invention includes the above-described microphone, acquires microphone unit position data desired by each user in advance, and attaches the user ID of each user to the microphone unit position data. The moving unit is controlled so that the moving position is based on the microphone unit position data storing unit for each user to be stored in a predetermined storage unit and the microphone unit position data corresponding to the user ID of the user who actually uses the microphone. And a moving position control means.

  In the microphone having such a configuration, the user ID can be added to the microphone unit position data desired by each user and stored in the storage means such as the HDD by the user-specific microphone unit position data storage means. . For example, when karaoke music is played on the karaoke device, the moving position control means controls the moving means based on the microphone unit position data corresponding to the user ID stored in the reservation queue, and the use The microphone unit is moved to a position desired by the person.

  In this case, the moving means includes, for example, a rack gear connected to the microphone unit, a pinion gear that meshes with the rack gear, and a stepping motor that rotates the pinion gear. When the user makes a music selection reservation, the user ID is added to the music ID and registered in the reservation queue. Thereby, user ID of the singer who actually uses a microphone (music selection reservation person) can be specified.

  Further, the microphone unit position data storage means for each user, for example, in the microphone set to the movement position setting mode, when the user who logs in to the karaoke system moves the microphone unit to a desired position, the microphone unit position data And a user ID is attached, and the program is stored in a storage device such as an HDD. The moving position control means is constituted by an electronic circuit and a program for transmitting a drive control signal to the stepping motor.

  According to the microphone of the present invention, the microphone unit can be moved in the longitudinal direction of the grip portion. Therefore, the position of the microphone unit can be adjusted so that the user's own voice can be clearly heard in a state where the microphone is held in a position that the user of the microphone (eg, a singer) can easily hold. Accordingly, even a user who is not familiar with the microphone operation technique can secure a suitable voice pressure while holding the microphone at a position where the user can easily hold the microphone.

  Further, in this karaoke system using a microphone, a desired microphone unit position is stored in advance for each karaoke user, and the microphone unit is moved so as to be a microphone unit position desired by a singer who actually uses the microphone. In the case of a configuration, even a singer who is not familiar with microphone operation technology can keep the microphone in a position that he or she can easily hold without adjusting the microphone position during singing or for each song. Therefore, it is possible to ensure a suitable voice pressure, to hear the singing voice clearly, and to fully enjoy the joy of singing.
