  By the way, the conventional hand-type microphone 100 shown in FIG. 6 has a tight grip portion (housing) 102 because the grip portion (housing) 102 has few portions to be caught when the user picks it up. Before gripping it, it may slip off your hand and drop it.

  In addition, when the position grasped when the user picks up the hand happens to be the antenna unit 104 side shown in FIG. 6, that is, a position far from the wind screen 101, the wind screen 101 is displaced from the user's mouth, It is also possible that the voice cannot be picked up well. On the other hand, when the user grips the wind screen 101 shown in FIG. 6 and holds the wind screen 101 as it is, the user's voice reverberates in the wind screen 101 and the user's voice cannot be picked up well. Is also possible.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a microphone that realizes a grip state in which good sound collection is possible while preventing the microphone from falling by making it easy to pick up the microphone.

In order to solve the above problem, the present invention is a hand-type microphone that is used by gripping a longitudinal housing with a hand, and has a sound collection unit in the housing, At one end in the longitudinal direction, a sound collection port for guiding an external sound to the sound collection unit and a finger hooking unit through which a human finger can be inserted are formed in the vicinity of the sound collection port. Features.

  With this configuration, when the microphone according to the present invention is taken out from, for example, a pocket or a charger holder, the user can hook the finger on the finger hook and pick it up in the hand, thereby preventing the microphone from dropping from the hand. Can do. In addition, by holding the microphone casing through the finger hooked part formed in the vicinity of the sound collection port, the sound collection port of the microphone can be reliably brought close to the user's mouth. Can be collected well.

The finger hooking part is for hanging through the index finger when in use, and is preferably formed so that the index finger is hooked behind the sound collection port. As a result, it is possible to realize a grip state in which the hand does not block the sound collection opening when the housing is gripped.

  An antenna unit for wirelessly transmitting the collected voice information or a light emitting unit for infrared transmission to the other end side opposite to the one end of the casing in which the sound collection port and the finger hook are formed May be provided. As a result, the position of the hand gripping the housing is brought closer to one end of the longitudinal microphone housing where the sound collection port and the finger hanging portion are formed, since the finger is hooked on the finger hanging portion. Therefore, it is possible to prevent the transmission radio wave of the antenna provided on the other end side or the emission of infrared rays from being disturbed.

  It is desirable that the finger hook portion has an annular shape or a notched annular shape through which a predetermined finger of a person is inserted. As a result, the microphone can be hooked with a finger and picked up by a hand, and a user's voice can be collected well by inserting the predetermined finger through the finger hook and holding the microphone Can be realized. In addition, the cyclic | annular said in this specification means the shape of the state which the edge of the hole connected even if it is any shape which consists of a combination of a circle, an ellipse, a semicircle, a polygon, a line, and a curve. . The notched ring means a shape in which a notch is formed in a part of the ring.

It is desirable that the housing has a curved gun grip shape. As a result, the user can grasp the optimum grip position without hesitation by making the case fit more easily in the hand and making it easier to grip and by visually identifying the grip position. Furthermore, since it is a gun grip shape, it can be visually wild.

In the microphone according to the present invention, a finger hook portion is formed in the vicinity of the sound collection port of the housing. Since the finger can be hooked on the finger-hanging portion and taken out from the pocket or the like, it is less likely that the finger is slid from the hand and dropped. Further, by gripping the housing by placing a predetermined finger on this finger hook portion, the vicinity of the sound collection port is grasped, and there is an effect that the sound collection port can be surely brought close to the mouth.

Although it is not recommended as a manufacturer, the performance of the finger of the microphone according to the present invention is similar to the performance of turning with a finger using the trigger protection part of a handgun, which is often seen in western movies. This can be realized by using the section. In that case, the annular shape is preferably a perfect circle.

Hereinafter, an embodiment of a microphone according to the present invention will be described with reference to the drawings.
FIG. 1 is a three-dimensional perspective view of the microphone 1, and FIG. 2 is a functional block diagram of the microphone 1.

  As shown in FIG. 1, the microphone 1 has a gun grip-shaped housing 2 in which a rectangular shape is gently curved in one direction perpendicular to the longitudinal direction. Here, the gun grip shape is literally a shape simulating the hand grip part (grip part) of the gun. There are various types of guns, such as pistols, rifles, machine guns, and bazookas, but their grips (grips) are gently curved in the barrel direction perpendicular to the longitudinal direction of the grips. Is common. The housing | casing 2 is shape | molded with resin and a metal.

A plurality of slit-like sound collection ports 4, 5, 6 are formed on the upper end surface of the housing 2, the front side surface near the upper end, and the left and right side surfaces. The sound collection ports 4, 5, 6 are holes for guiding external sound to the sound collection unit 10 built in the housing 2, and are formed on the upper end surface due to the sound collection directivity characteristics of the sound collection unit 10. The sound collection port 4 is the main sound collection port.

Four slits of the sound collection port 4 are formed in parallel to the longitudinal direction of the upper end surface. Further, four slits of the sound collecting port 5 formed on the front side surface on the upper end side are formed in a direction perpendicular to the longitudinal direction of the front side surface. An input terminal 9 for receiving an input from an external microphone is provided on the upper end surface.

The slits of the sound collection port 6 are formed on the right side on the upper end side, and three slits are formed in parallel so as to continue with the three slits on the lower side of the sound collection port 5. A similar slit is also formed on the left side surface on the upper end side which is not shown in FIG.

An annular finger hook 3 is formed at the position on the back side of the housing 2 facing away from the sound collection opening 5 so as to open in the left and right side surfaces of the housing 2. This annular opening is an image of a trigger protection part that protects the trigger of the gun. Similar to the trigger protection part of the gun, the point of passing the finger is the same. The ring shape is a perfect circle, and is a size of a little over 500 yen so that a general person's index finger can pass sufficiently, so it is very different from the trigger protection part of a gun. Further, as shown in FIG. 1, half of the ring of the finger hook 3 protrudes from the rectangular lines on the left and right side surfaces of the loosely curved housing 2.

  A push-to-talk button 7 that is assumed to be operated with a thumb is provided on the front side surface of the housing 2. When the push-to-talk button 7 is pressed once while the power is on, the sound collecting unit 10 enters the sound collecting state, and when pressed again, the sound collecting unit 10 enters the non-sound collecting state.

  An anti-slip notch pattern is formed on the rear side surface and the left and right side surfaces of the housing 2. A power input unit 8 for charging the built-in battery unit 14 by being connected to a charging holder (not shown) is provided on the lower end surface of the housing 2.

Next, the functional configuration of the microphone 1 will be described with reference to FIG. 2. Since the basic configuration is the same as that of a conventional wireless microphone, a brief description will be given.

  The microphone 1 includes a function unit such as a sound collection unit 10, an amplification circuit 11, an FM modulation circuit 12, an antenna unit 13, a battery unit 14, and a power input unit 8 in the housing 2.

  The sound collection unit 10, which is also called a microphone unit, has a function of converting sound waves that have entered the housing 2 through the sound collection ports 4, 5, 6 into audio signals (electrical signals). An audio signal generated by the sound collecting unit 10 or an external microphone connected to the input terminal 9 is input to the amplifier circuit 11.

The amplifier circuit 11 has a function of amplifying and adjusting the signal level of the input audio signal. The audio signal whose signal level is amplified and adjusted is input to the FM modulation circuit 12.

The FM modulation circuit 12 has a function of FM-modulating the input audio signal. The modulation signal subjected to FM modulation is wirelessly transmitted from the antenna unit 13.

Although not shown, the wirelessly transmitted modulated signal is received by the antenna of the corresponding receiver and demodulated, and the demodulated audio signal is amplified through an amplifier and a speaker.

The power input unit 8 has a terminal for receiving power supply by connecting to a charging holder (not shown) on the outer surface of the housing 2, and the supplied power is charged in the battery unit 14.

Next, the use situation of the microphone 1 will be described with reference to FIGS. FIG. 3 is a diagram illustrating a situation in which the microphone 1 is taken out from the pocket. The user can pick up the microphone 1 from the pocket 60 by hooking it on the finger hook 3 through the index finger 51 of the user.

FIG. 4 is a diagram illustrating a gripping state of the microphone 1. From the state where the index finger 51 is hooked on the finger hook portion 3 as shown in FIG. 3, it is possible to make the gripping state as shown in FIG. However, it is not recommended for beginners because the index finger 51 may drop out of the hole of the finger hook portion 3 and the microphone 1 may fly away unless they are used to it.

  Basically, it is desirable to pick up the index finger 51 on the finger hook 3 and lift it with both hands. Then, the index finger 51 is again passed through the finger hook 3, the thumb 52 is hung on the front side surface of the housing 2, and the other fingers are hung on the rear side surface of the housing 2, and the entire palm is held. At this time, the antenna 13 built in the housing 2, which is indicated by a dotted line in FIG. 4, is arranged on the lower end side of the housing 2 so as not to cover the user's hand 50. It can transmit well without being interrupted.

  The present invention is not limited to the above-described embodiment. The following modifications are also conceivable.

FIG. 5 is a three-dimensional perspective view of the microphone 1A in which the finger hook portion 3A is formed in a cutout annular shape. Since the above-described microphone 1 is a perfect circular ring and can be rotated with a round, it can be used as a performance as described above.

However, the performance is not a problem as long as you practice and rotate with the work as a work, but in play, turn with the twist and hit yourself and others, finger with the momentum There is a possibility that a problem may occur that the user gets out of the box and skips it. When such a problem has surfaced, it is conceivable to make it difficult or impossible to rotate by twisting a part of the ring-shaped finger hook portion into a notched ring.

  In addition, as a method of making it difficult to rotate with the kurukuru, it is also conceivable to make the ring of the finger hook portion 3 into a triangular shape, a square shape, or a gnagged shape.

The case of the microphone 1 of the above-described embodiment is formed with a notch pattern for preventing slipping. However, the case may be formed with unevenness according to the swelling of each finger of the hand when grasped. .

  Although the microphone 1 of the above-described embodiment has been described as a wireless microphone, any transmission method may be used. For example, the present invention may be applied to an infrared communication microphone. In this case, the infrared light emitting section is opposite to one end of the casing on which the sound collection port and the finger hook section are formed, that is, in the vicinity of the antenna section 13 shown in FIG. It is desirable to provide on the rear side of the body 2. Thereby, since the grip position is brought close to the sound collection port depending on the position of the finger hook portion 3, it is possible to prevent the hand from covering the light emitting portion when gripping.

The present invention can also be applied to a wired microphone. Further, the antenna may protrude outside the housing, or may be provided at a position other than the lower end of the housing.

  The microphone according to the present invention is not limited to a user performing on the stage, but as a notification microphone in a pachinko store, or as a microphone for calling in a supermarket side dish corner or meat corner, etc. Useful in various industries.
