Description

  The present invention relates to a microphone switch, and more particularly to a microphone switch that can prevent vibration noise without impairing a sense of moderation (click feeling) during switch operation.

  For example, in a karaoke store, a handheld dynamic microphone is used, but when not in use, a switch for turning off the function of the microphone is used (see, for example, Patent Document 1). As shown in the circuit of FIG. 8, the switch 51 is used to short-circuit the output of the dynamic microphone 60 when not in use so that no audio signal is output. In general, a slide switch 51 as shown in FIG. 7 is often used as the switch.

  In the slide switch 51, the connection between the terminal 53 and the terminal 54 or the connection between the terminal 54 and the terminal 55 is switched by sliding the knob 52. The sliding operation of the knob 52 has a structure with a feeling of moderation (click feeling) in order to give the user a sense of operating the switch with certainty.

JP 2014-045357 A

However, when the knob 52 is slid, the microphone case vibrates and vibration noise is generated when the switch is turned off.
On the other hand, if the feeling of moderation when sliding the knob 52 is weakened to reduce vibration noise, there is a problem that the user himself cannot be sure whether or not the switch can be operated reliably.

  The present invention has been made paying attention to the above points, and an object of the present invention is to provide a microphone switch capable of reducing vibration noise without impairing the sense of moderation when the switch is operated.

In order to solve the above-described problem, a microphone switch according to the present invention includes a knob body and a decorative knob that covers a side surface and an upper surface of the knob body, and the switch is switched off by sliding the knob body. A microphone switch that includes an elastic member that is provided on an upper surface side of the knob body and that urges the decorative knob in a direction away from the upper surface of the knob body, and that pushes the decorative knob and compresses the elastic member. And a second switch that closes the contact when the knob body is slid. The contact of the first switch is a conductive cloth or a resistor that is applied by applying pressure. It is characterized in that it includes a resistance member whose value decreases and becomes conductive .
The elastic member is preferably formed of a sponge.

  As described above, according to the present invention, since the push switch (first switch) is operated, that is, the slide switch (second switch) is operated in a state where the voice output is short-circuited by pushing the decorative knob, A moderation feeling can be obtained, and the generation of vibration noise can be prevented without losing the operational feeling.

  According to the present invention, vibration noise can be reduced in a microphone switch without impairing moderation when the switch is turned off.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a sectional view of a microphone switch according to the present invention. FIG. 2 is an equivalent circuit showing the state of the microphone switch of FIG. FIG. 3 is a cross-sectional view showing different states of the microphone switch of FIG. 1 (a state where the knob is pressed). FIG. 4 is an equivalent circuit showing the state of the microphone switch of FIG. FIG. 5 is a cross-sectional view showing different states of the microphone switch of FIG. 1 (sliding knob).

As shown in FIGS. 1, 3, and 5, the microphone switch 1 according to the present invention is slidably provided along a slit-shaped switch hole 10 a provided on the side surface of the microphone body 10.
Specifically, a hard decorative knob 2 made of a plastic material or the like is inserted from the back side of the switch hole 10a and is arranged so as to protrude to the front side. Further, a plate-like slider 5 is formed so as to spread from the lower end of the decorative knob 2 to the periphery. When the decorative knob 2 is pushed in, the slider 5 also sinks downward to create a gap between the back surface of the microphone body 10 and the microphone switch 1 can slide along the back surface of the microphone body 10 in the longitudinal direction of the switch hole 10a. It is like that.

Further, the inside of the decorative knob 2 is formed in a cavity, and a hard knob main body 4 made of a plastic material or the like is disposed therein (the decorative knob 2 covers the side surface and the upper surface of the knob main body 4). Further, an elastic member 3 having a predetermined thickness made of, for example, sponge is provided on the upper surface side of the knob body 4, that is, on the ceiling portion inside the decorative knob 2. The elastic member 3 biases the decorative knob 2 in a direction to pull it away from the knob body 4.
Since the decorative knob 2 is slidable in the vertical direction with respect to the knob body 4, when the decorative knob 2 is pushed downward with a fingertip, the elastic member 3 is compressed, and the decorative knob 2 and the slider 5 are moved downward. When the fingertip is moved away from the makeup knob 2, the makeup knob 2 is moved upward by the elastic force of the elastic member 3.

Also, below the switch hole 10a, a substrate 6 on which a slit (not shown) in which the knob body 4 can slide is formed, and a switch casing 7 fixed to the lower surface side (back surface side) of the substrate 6. And are provided. The switch casing 7 has a slide switch structure in which contacts are switched by a sliding operation of the knob body 4.
Specifically, for example, in the state of FIG. 1, the terminal 12 and the terminal 13 are connected as shown in the circuit of FIG. 2, the contact is opened, and in the state of sliding the knob as shown in FIG. As shown in this circuit, the terminal 11 and the terminal 12 are connected, and the contact is closed.

A plate contact 22 is provided on the upper surface of the substrate 6.
On the other hand, a conductive cloth 21 is provided on the back surface of the slider 5 that can slide when the decorative knob 2 is pushed.

In a state where the decorative knob 2 is not pushed in, the conductive cloth 21 and the plate-like contact 22 are not in contact with each other as shown in FIGS. 1 and 2 (reference numeral 30 is a dynamic microphone in FIG. 2). From this state, as shown in FIGS. 3 and 4, when the decorative knob 2 is pushed in, the elastic member 3 is compressed, and the slider 5 sinks downward to bring the conductive cloth 21 and the plate contact 22 into contact with each other. The contact is closed (first switch 1A).
Further, by sliding the makeup knob 2 (knob body 4) as shown in FIGS. 5 and 6 from the state in which the makeup knob 2 is pushed as shown in FIG. 3, the terminal 12 and the terminal 11 of the slide switch are connected. The contact is closed (second switch 1B).

  In the microphone switch 1 configured as described above, for example, the switch-off state shown in FIGS. 1 and 2 (the state where the contact of the first switch 1A is opened and the terminal 12 and the terminal 13 of the second switch 1B are connected) ) To the switch-on state shown in FIGS. 5 and 6 (the state where the contact of the first switch 1A is closed and the terminal 11 and the terminal 12 of the second switch 1B are connected). First, the person grasps the microphone body 10 and pushes the makeup knob 2 with his fingertip. As a result, the elastic member 3 is compressed, and the slider 5 sinks downward as shown in FIG. 3, and the conductive cloth 21 on the back side of the slider 5 and the plate-like contact 22 on the substrate 6 are electrically connected, and the short circuit state. It is made. Here, when the conductive cloth 21 comes into contact with the plate-like contact 22, the conductive cloth 21 absorbs vibration during operation, so that noise when the contact is closed is suppressed. Further, the elastic member 3 prevents the makeup knob 2 and the knob body 4 from coming into direct contact with each other, so that the generation of the contact sound is suppressed.

Next, when the makeup knob 2 (knob body 4) is slid from the state in which the makeup knob 2 is pushed in as described above, the terminal 11 and the terminal 12 of the slide switch are connected. In the operation of this slide switch, a sliding feeling can be obtained because the slide operation is performed with the makeup knob 2 pushed in.
Here, when the operator releases the fingertip, the slider 5 rises together with the decorative knob 2, and the connection between the conductive cloth 21 and the plate contact 22 is released, but the terminals 11 and 12 of the slide switch are connected. Therefore, the short circuit state is maintained. Thereby, generation | occurrence | production of the vibration noise at the time of switch-off operation is prevented.

  As described above, according to the embodiment of the present invention, the operation of the push switch (first switch 1A), that is, the slide switch (second switch) with the voice knob short-circuited by pressing the makeup knob 2 is performed. Since 1B) is operated and the short circuit state is maintained, a feeling of moderation can be obtained, and the generation of vibration noise can be prevented without losing the feeling of operation.

In the above embodiment, the conductive cloth 22 is provided on the back side of the slider 5 in order to form a contact point. However, in the present invention, the configuration is not limited thereto.
For example, instead of the conductive cloth 22, a resistance member (for example, a carbon material) that has a resistance value that decreases due to application of pressure and that conducts may be used. In that case, since the resistance value decreases when the pressure to push the decorative knob 2 increases, an inadvertent switch-off operation can be prevented.
