Description

[Detailed explanation of the idea] The present invention relates to a portable loudspeaker.

Conventional hand-held portable loudspeakers have a microphone built into the rear end of the megaphone body, and when in use, the megaphone body must be held accurately so that the relative position between the microphone and the mouth is always constant when emitting sound. Due to severe fatigue, the input of the microphone is only on one side, which can easily cause howling due to surrounding noise being mixed in. In addition, if you are pushed by a crowd while using it, or if you are using it in a car, the back end of the megaphone body and face may be damaged due to shaking. However, there are some difficulties in using it, such as injuries caused by collisions with lips, etc., and when using it as a shoulder type, another microphone must be switched and connected to the built-in microphone at the rear of the main unit, and two microphones are required. There was complexity.

In this invention, a support body with a microphone holder attached to the microphone stand provided in an appropriate position on the main body of the megaphone is attached to the microphone stand so that it can be pulled out to the rear via a connecting mechanism that can be slid and extended. Grip 1 is a device in which a talk switch capable of opening/closing the microphone circuit and maintaining the closed state is provided, the main body is connected with a curl cord, and the microphone is detachably supported on the holder.
, a microphone stand 4 is provided at an appropriate position on a megaphone body 3 having a shoulder band 2, and a support body 9 on which a microphone holder 7 that fits into an insertion hole 6 of a microphone 5 is attached in a freely undulating manner with a hinge 8 is placed on the microphone stand 4. It is connected and supported to the microphone stand 4 by a telescoping mechanism A that can be pulled out rearward from the microphone stand 4.

FIG. 2 shows an example of the telescopic mechanism A, in which the support body 9 is plate-shaped, and outward latching protrusions 10 are provided on both sides opposite to the holder 7.
, and at one end of the sliding frame 11 that can fit and slide the protrusion,
An inward stopper 12 that slides on the side of the support 9 and a locking protrusion 10 are provided on both sides of the other end. The sliding surface on the inside of the latch projection 10 and the sliding frame 11 is made to be able to slide only in the horizontal direction by a dovetail groove or a concave-convex fitting 13, and the sliding frame 11 is provided on the upper surface of the microphone stand 4. After fitting into the fixing frame 14 having the same structure as above, fix the appropriate retaining plate 15, insert and support the microphone holder 7 into the insertion hole 6 of the microphone 5, and attach the microphone 5 to the microphone stand 4.
The microphone 5 is connected to the main body 3 with a curl cord 16 so that the microphone 5 can be pulled out to the rear at any time to stand up.

The talk switch B houses a microswitch 20 provided in the case 17 of the microphone 5 and equipped with an operating protrusion 19 that is pressed by a lever 18, and has a seat plate 22 fixed to a rotation shaft 21 supported by the case. The legs 25 of the push button 24 are inserted into the long holes 23 of the seat plate 22 along the inner surface of the case 17.
One end of a leaf spring 26 is fixed to the plate spring 26, and a bending protrusion 27 is formed on the other end of the leaf spring 26. When the push button 24 is pressed, the leaf spring 2
6. Press the operating protrusion 19 via the lever 18 and press the push button 24
When the pressure is released, the operating protrusion 19 automatically returns to its original state, and when the push button 24 is slid along the long hole 23, the bent protrusion 27 rides on the seat plate 22, and the lever 18 is pressed to press the operating protrusion 19. and maintains the closed state of the microswitch 20.

Since the present invention is constructed as described above, the sliding frame 11,
Push the support body 9 onto the microphone stand 4 and attach the holder 7.
The microphone 5 inserted into the microphone 5 can be carried on a patrol with the microphone 5 tilted forward, and when in use, the sliding frame 11 and the support body 9 can be pulled out to the rear to an appropriate position and the microphone 5 can be used as a hand type. Microphone 5
Since the microphone is placed above the main body 3, it is possible to prevent the risk of the face or lips colliding with the rear end of the main body, and since the microphone is placed above the main body, the main body can be supported at a lower position, reducing fatigue caused by supporting the main body. .

In addition, if you use a double-sided microphone, it will operate as a differential type that cancels out surrounding noise, reducing howling due to noise, making the voice emitted clearer, and making it easier to see in front of you.The microphone can also be used as a normal talk switch by pressing and releasing the push button. In addition, the operating state can be maintained by sliding, which greatly improves usability. When using the microphone as a shoulder type, just by removing the microphone from the holder, the support body 9 and sliding frame 11 can be pushed onto the microphone stand 4. It does not get in the way and can be used for both hand and shoulder microphones with a single microphone.

It should be noted that the extension/contraction mechanism for pulling out the microphone is not limited to the structure of the above-mentioned embodiments, and may employ, for example, a square tube fitting or other extendable/contractable mechanism.

Moreover, the sliding frame 11 can be made into a plurality of pieces and can be expanded and contracted in three or four stages.
