Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a microphone device, and more particularly to a microphone device that includes an external microphone and can be used for both desktop use and wall-mounted use.
[0002]
[Prior art]
Conventionally, as shown in FIG. 4, a microphone device used in a condominium management room or a hospital has a microphone fixing hole 2 ′ for fixing an external microphone 3 ′ on a front surface 1a ′ of a housing 1 ′. The threaded end of the external microphone 3 ′ is inserted into the microphone fixing hole 2 ′ and tightened with the nut 4, and the external microphone 3 ′ is directly fixed to the housing 1 ′. Has been.
[0003]
In general, this type of microphone device is often manufactured on the assumption that the external microphone 3 ′ is attached on a desk.
[0004]
[Problems to be solved by the invention]
When using a microphone device with an external microphone 3 ′ on the table, the external microphone 3 ′ should be on the front surface 1a ′ of the housing 1 ′. However, when the microphone device is used in a wall-mounted manner. However, there is a problem that the external microphone 3 ′ jumps out of the wall surface, is unusable and has a poor appearance.
[0005]
However, the mounting position of the external microphone 3 ′ is fixed and cannot be changed, and in order to cope with this, there has been a problem that another housing must be manufactured for the wall mounting type.
The present invention has been made in view of the above-mentioned problems, and an object thereof is to provide a microphone device that can be used for both desktop use and wall-mounted use.
[0006]
[Means for Solving the Problems]
In order to achieve this object, the microphone device of the present invention includes a microphone holder that holds an external microphone, and a casing in which a rectangular parallelepiped fitting portion that holds the microphone holder is recessed, The rectangular parallelepiped joint portion has the same shape on the two adjacent surfaces of the casing, and a holder fixing screw hole for fixing the microphone holder is provided on the opposite side of the two adjacent surfaces. The microphone holder is provided with a microphone fixing hole to which the microphone is fixed and a holder screw hole to which a screw is screwed from the holder fixing screw hole of the housing. The screw holes facing the surface having the microphone fixing hole and the screw holes facing the surface adjacent to the surface having the microphone fixing hole are formed in two directions.
[0007]
According to the microphone device of the present invention, the holder screw holes of the microphone holder are arranged in two directions: a screw hole facing the surface having the microphone fixing hole and a screw hole facing the surface adjacent to the surface having the microphone fixing hole. Since one of the holder screw holes can be selected and the microphone holder can be repositioned and fixed to the housing by 90 degrees, it can be used for both desktop use and wall mounting use. It becomes possible to respond.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of the microphone device of the present invention will be described with reference to the drawings.
As shown in FIG. 1, the microphone device of the present invention is a microphone device including an external microphone 3 used in a condominium management room, a hospital, or the like, and a microphone holder 5 that holds the external microphone 3. And a rectangular parallelepiped coupling portion 9 that mates with the microphone holder 5 and a housing 1 that is recessed at the corners.
[0009]
The rectangular joint 9 has two surfaces 1a and 1b adjacent to the casing 1 (hereinafter referred to as the front of the casing and the top of the casing, respectively) having the same shape (x = y). Two holder fixing screw holes 7 for fixing the microphone holder 5 are drilled through the casing 1 on the side facing the casing front 1a.
As shown in FIGS. 1 and 2, the microphone holder 5 is attached to two adjacent surfaces 5a and 5b (hereinafter referred to as the holder front surface, the holder upper surface, and ) Has the same shape (x = y), and a microphone fixing hole 2 for fixing the external microphone 3 is provided in one of the holder front faces 5a, and is connected to the holder front face 5a and the holder upper face 5b. The two ribs 5 c and 5 d are provided with a holder screw hole 8 into which the screws 6 and 6 are screwed from the holder fixing screw holes 7 and 7 of the housing 1.
[0010]
The holder screw hole 8 is formed in two directions: screw holes 8a and 8a facing the holder front surface 5a and screw holes 8b and 8b facing the holder upper surface 5b.
Next, the operation of the microphone device of the present invention will be described.
First, as shown in FIG. 1, the external microphone 3 is fixed to the microphone holder 5. That is, the threaded end of the external microphone 3 is inserted into the microphone fixing hole 2 of the microphone holder 5 and tightened with the nut 4 to fix the external microphone 3 to the microphone holder 5.
[0011]
When the microphone device of the present invention is mounted on the wall, as shown in FIG. 3A, the microphone holder 5 to which the external microphone 3 is fixed is attached to the mating portion 9 of the housing 1. The holder front surface 5a of the microphone holder 5 is attached to the upper surface 1b of the casing 1, and the holder upper surface 5b of the microphone holder 5 is positioned to the front surface 1a of the casing 1, and screws are screwed into the screw holes 8b and 8b. 6 is screwed to fix the microphone holder 5 to the housing.
[0012]
When using the microphone device of the present invention on a table, as shown in FIG. 3B, when attaching the microphone holder 5 to which the external microphone 3 is fixed to the mating portion 9 of the housing 1, The holder front 5a of the microphone holder 5 is attached to the front 1a of the casing 1 and the holder upper face 5b of the microphone holder 5 is positioned on the upper face 1b of the casing 1, and the screw 6 is inserted into the screw holes 8a and 8a. And the microphone holder 5 is fixed to the housing 1.
[0013]
Since the microphone holder 5 of the microphone device of the present invention has the holder screw holes 8a and 8b whose directions are different by 90 degrees, the microphone holder 5 is fixed to the housing 1 by changing the position by 90 degrees depending on the selection. It is possible to easily change the drawing direction of the microphone in a direction that is convenient for desktop use and wall-mounted use. Since the change in the direction of drawing out the microphone can be carried out without producing a separate housing, the change in the direction of drawing out the microphone at the delivery site is also easy.
[0014]
【The invention's effect】
As is clear from the above description, in the microphone device of the present invention, the holder screw hole of the microphone holder faces the surface adjacent to the surface having the screw hole and the microphone fixing hole facing the surface having the microphone fixing hole. Since one of the holder screw holes can be selected, the microphone holder can be fixed at a 90-degree position relative to the housing. It can correspond to each of mounting use. Since the microphone drawing direction can be changed without producing a separate housing, it is also easy to change the microphone drawing direction at the delivery site.
