A stand for microphones according to one embodiment of the present invention has: a male connector of a gooseneck microphone having the male connector at an end and a detachable female connector; an upper housing in which is formed a through-hole through which the end of the microphone can be inserted; a lower housing sealed by the upper housing; a pair of support beams supported on the lower housing; and a tabular stay, extended between the pair of support beams so as to be spaced away from the upper housing, for holding the female connector directly below the through-hole.

Description

Microphone stand and microphone device

The present invention relates to a microphone stand and a microphone device.

For example, as a microphone device used for in-house broadcasting or the like, a gooseneck type microphone (a microphone having a curved arm and a sound collecting unit disposed at the tip of the arm) is placed on a microphone stand placed on a table. In general, a connector is detachably mounted using a connector. In such a microphone device, in general, an opening for inserting the end of the microphone is formed in the upper casing of the microphone stand (the lid that seals the upper opening of the lower casing that accommodates the circuit board and the like) A connector is fixed to the inner surface side of the housing (see Japanese Patent Application Laid-Open No. 2009-188793).

In the microphone device, since an operation member such as a switch for enabling or disabling a function is usually provided in the upper casing, a user's hand or other object is likely to collide with the upper casing. When vibration is generated by a hand or another object hitting the upper housing, this vibration is transmitted to the microphone via the connector, and the microphone may collect noise.

It can be considered that noise conduction to the connector can be reduced by providing a microphone connector in the lower housing apart from the upper housing. However, if a connector is provided in the lower housing, the accuracy of the relative position between the opening of the upper housing and the connector is lowered, so it is necessary to enlarge the opening of the upper housing formed to insert the end of the microphone. There is an unnatural gap in the microphone stand.

JP 2009-188793 A

In view of the above inconveniences, an object of the present invention is to provide a microphone stand and a microphone device in which vibration is not easily transmitted to the microphone.

A microphone stand according to an aspect of the present invention, which has been made to solve the above problems, includes a gooseneck microphone having a male connector at its end, a female connector that can be attached to and detached from the male connector, and an end of the microphone. An upper housing in which a through-hole is inserted, a lower housing sealed by the upper housing, a pair of support beams supported by the lower housing, and the upper housing between the pair of support beams It has a plate-like stay that is spanned away from the body and holds the female connector directly below the through hole.

Since the microphone stand holds the female connector by a stay that is separated from the upper housing between the pair of support beams, the vibration of the upper housing is not directly conducted to the female connector. Vibration is difficult to conduct.

In the microphone stand, it is preferable that the upper housing is fixed to the support beam at a position different from the stay. According to this configuration, since the stay and the upper housing are held by the support beam, the relative position between the stay and the upper housing is relatively accurate. Therefore, the through hole of the upper housing is relatively small. Thus, the gap between the microphone stands can be reduced.

In the microphone stand, the support beam is formed by bending a metal plate, and has a tongue-like stay support portion to which the stay is fixed, the stay is formed by bending the metal plate, and It is preferable to have a tongue-like fixing portion that is bent and extended a plurality of times and is fixed to the support portion. According to this configuration, since the support beam and the stay are formed by bending the metal plate, vibration is easily absorbed. In addition, since the stay support portion and the fixed portion that can absorb vibration more are connected by being formed in a tongue shape, the conduction of vibration from the support beam to the stay can be more reliably suppressed. Furthermore, since the deformability is increased by extending the bent portion by bending a plurality of times, the conduction of vibration can be further suppressed.

In the microphone stand, the support beam has a main portion arranged vertically, and a rib extending continuously in a horizontal direction from a lower edge of the main portion and fixed to the lower housing, It is preferable that the stay support portion extends in the horizontal direction from the upper edge of the main portion. According to this configuration, since the main portion exists between the rib fixed to the lower housing and the stay support portion, vibration is easily absorbed.

In the microphone stand, it is preferable that the support beam further includes a housing support portion that extends in a horizontal direction from an upper edge of the main portion independently of the stay support portion and to which the upper housing is fixed. . According to this configuration, vibration transmission from the housing support portion to the fixing portion can be more reliably suppressed by separating the fixing portion and the housing support portion.

A microphone device according to another aspect of the present invention includes a gooseneck type microphone having a microphone stand and a male connector attached to the female connector of the microphone stand.

The microphone stand and microphone device of the present invention are less likely to transmit vibration from the microphone stand to the microphone.

It is a typical perspective view which shows the microphone apparatus of one Embodiment of this invention. It is a typical disassembled perspective view of the stand for microphones of the microphone apparatus of FIG.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as appropriate.

[Microphone device]
FIG. 1 shows a microphone device according to an embodiment of the present invention.

The microphone device is mainly used for private broadcasting, and can select an area where sound is played, specifically a speaker or a group of speakers to be used. Note that “on-site broadcasting” means that audio is sent to all or a part of an area such as a hospital, a conference room, or an office, for example, the whole or a part of an outdoor facility such as an amusement park or a shopping center However, the type and size of the area where audio is played are not limited.

The microphone device includes a gooseneck type microphone 1 and a microphone stand 2 that is placed on a table or the like and to which the microphone 1 is attached. The microphone stand 2 itself is another embodiment of the present invention.

〔microphone〕
The microphone 1 includes a sound collection unit 3 that converts sound waves (air vibrations) into an electrical signal, a support arm 4 that supports the sound collection unit 3 at one end and can be bent, and a sound collection unit of the support arm 4. 3 and a male connector 5 disposed on the opposite end.

As such a microphone 1, a commercially available one can be used. For this reason, the male connector 5 is preferably a male terminal of a Canon XLR connector, which is the de facto standard, or a compatible product thereof. On the other hand, the sound collection unit 3 and the support arm 4 can be appropriately selected according to, for example, a place where the microphone device is disposed, a place where sound is played, and the like.

[Stand for microphone]
The microphone stand 2 includes a lower housing 6 having an upper opening and an upper housing 7 that seals the upper opening of the lower housing 6, and a talk button 8 that activates the function of the microphone device; A plurality of selection buttons 9 for selecting a broadcast area are arranged so as to protrude from the surface of the upper housing 7. That is, the microphone device can select a broadcast area with the selection button 9 and perform private broadcasting while the talk button 8 is pressed (so-called push-to-talk). The upper housing 7 is formed with a through hole 10 into which an end portion of the microphone 1 (engagement portion of the male connector 5) can be inserted.

As shown in FIG. 2, the microphone stand 2 includes a male connector 5 of the microphone 1, a detachable female connector 11, a pair of support beams 12 supported by the lower housing 6, and a pair of supports. A plate-like stay 13 is provided between the beams 12 so as to be separated from the upper housing 7 and holds the female connector 11 directly below the through hole 10.

<Lower case>
The lower housing 6 is a main body of a casing that houses the female connector 11 and other electronic components and a circuit board. The lower housing 6 has a weight and can be formed of, for example, zinc die cast that can suppress vibration.

The lower housing 6 has a plurality of convex portions 14 to which the support beams 12 are fixed on both inner side portions. Further, the lower housing 6 may have a vibration isolating leg or a vibration isolating pad formed of rubber or the like on the bottom surface.

<Upper housing>
The upper housing 7 is a decorative cover for sealing the lower housing 6 to protect internal components and improving the appearance of the microphone stand 2. The upper housing 7 is indirectly attached to the lower housing 6 by being fixed to a support beam 12 described later.

As the upper casing 7, for example, a metal plate such as an aluminum plate that is press-molded can be used. The average thickness of the upper housing 7 can be, for example, 1.2 mm or more and 2.5 mm or less.

It is preferable that the upper housing 7 is inclined so that the heel side is raised so that the talk button 8 and the selection button 9 can be easily operated. On the other hand, the through hole 10 is preferably formed so as to penetrate the upper housing 7 in the attaching / detaching direction of the male connector 5 regardless of the inclination of the surface of the upper housing 7, that is, formed in the vertical direction. .

<Support beam>
The support beam 12 is formed by bending a metal plate, for example, by press molding. Specifically, the support beam 12 is the same as the main portion 15 arranged vertically, the fixed rib 16 continuously extending in the horizontal direction from the lower edge of the main portion 15, and the fixed rib 16 from the upper edge of the main portion 15. A tongue-like stay support portion 17 that extends horizontally to the side and to which the stay 13 is fixed, and extends from the upper edge of the main portion 15 independently from the stay support portion 17 in the horizontal direction on the same side as the fixing rib 16, And a housing support portion 18 to which the upper housing 7 is fixed.

Since the upper housing 7 having the through-hole 10 and the stay 13 holding the female connector 11 into which the male connector 5 is inserted through the through-hole 10 are connected via the support beam 12, the through-hole 10 and the female The relative position with respect to the mold connector 11 is relatively accurate. As a result, the size of the through hole 10 can be made close to the size of the male connector 5, and the gap between the upper housing 7 and the microphone 1 can be reduced.

In the pair of support beams 12, the fixing ribs 16 are fixed on the convex portions 14 provided on both sides of the lower housing 6 so that the fixing ribs 16, the stay support portions 17, and the housing support portions 18 face each other. In other words, the support beam 12 is fixed at several locations so that portions other than the fixing location to the lower housing 6 are separated from the lower housing 6. The support beam 12 can be fixed to the lower housing 6 with, for example, screws.

In the support beam 12, the stay support portion 17 is provided at a position different from the position fixed to the lower housing 6 in plan view. Therefore, a portion of the support beam 12 that is separated from the lower housing 6 exists between the convex portion 14 and the housing support portion 18. In other words, the stay support portion 17 is provided at a portion of the support beam 12 that is floating from the lower housing 6. For this reason, it is difficult for vibration to be transmitted from the lower housing 6 to the microphone 1.

Further, the housing support portion 18 is provided at a position overlapping with one of the fixing portions to the lower housing 6 in plan view. Therefore, a portion of the support beam 12 that is separated from the lower housing 6 exists between the stay support portion 17 and the housing support portion 18. For this reason, the vibration of the upper housing 7 is relatively easy to conduct from the housing support 18 to the lower housing 6, but is relatively difficult to conduct to the stay 13 supported by the stay support 17. Accordingly, the microphone device is unlikely to transmit vibration from the microphone stand 2 to the microphone 1.

As the metal plate forming the support beam 12, for example, a plated steel plate or the like can be used. Moreover, as an average thickness of the metal plate which forms the support beam 12, it can be 0.8 mm or more and 1.5 mm or less, for example.

The stay support portion 17 is formed to extend from the upper edge of the main portion 15 in a tongue shape independent of other components. As a result, the stay support portion 17 is easily elastically deformed, can attenuate the vibration conducted from the main portion 15, and can suppress the transmission of the vibration to the stay 13. In addition, extending in the shape of a tongue means that the member is extended to a shape such as a rectangle or an ellipse in a specific direction.

The average width of the stay support portion 17 may be, for example, 8 mm or more and 15 mm or less.

The distance from the main portion 15 to the center of the position where the stay 13 of the stay support portion 17 is fixed can be, for example, 5 mm or more and 10 mm or less.

On the other hand, the distance from the main part 15 to the center of the position where the upper casing 7 of the casing support 18 is fixed is preferably as small as possible so that the upper casing 7 can be firmly held. It is recommended that the distance is the minimum necessary for the purpose.

The stay support portion 17 and the housing support portion 18 are preferably formed with holes so that the stay 13 and the upper housing 7 can be fixed using screws. In this case, it is more preferable that a rise is formed around the hole so that screws can be directly screwed into the stay support portion 17 and the housing support portion 18.

<Stay>
The stay 13 holds the female connector 11 so that the attaching / detaching direction of the male connector 5 becomes the vertical direction in a state where the microphone stand 2 is placed on a horizontal table. Thus, by making the attachment / detachment direction of the male connector 5 the vertical direction, the attachment / detachment of the microphone 1 to / from the microphone stand 2 is facilitated.

The stay 13 can be formed by bending a metal plate in the same manner as the support beam 12. The stay 13 is bent in a plurality of steps and then extends so as to protrude sideways, and a pair of tongue-like fixing portions 19 fixed to the stay support portion 17 of the support beam 12 and a front edge portion are bent. And reinforcing ribs 20 to be formed.

The stay 13 is easily deformed elastically by bending the fixing portion 19 a plurality of times, attenuates the vibration conducted from the support beam 12, and reduces the vibration conducted to the female connector 11.

<Female connector>
The female connector 11 is a connector corresponding to the male connector 5 and also serves to hold the microphone 1.

The male connector 5 may have a lock mechanism for fixing in a state where the female connector 11 is mounted. Since the female connector 11 has the lock mechanism, it is possible to prevent the microphone 1 from being unintentionally detached from the microphone stand 2 and the sound being interrupted during broadcasting. As the female connector 11 having such a locking mechanism, for example, the one described in Japanese Patent Application Laid-Open No. 2009-188793 can be used.

<Advantages>
In the microphone device, the female connector 11 is held by the stay 13 spanned between the pair of support beams 12 so as to be separated from the upper housing 7, so that the vibration of the upper housing 7 is directly transmitted to the female connector 11. do not do. For this reason, since the microphone device is unlikely to conduct vibration from the microphone stand 2 to the microphone 1, it is difficult to collect noise.
