Description

[Detailed description of the invention] This invention is a portable transmitter, loudspeaker, transceiver,
This invention relates to small electronic devices that use microphones, such as tape recorders.

Traditionally, this type of small electronic device with a microphone has
There were some that had a microphone built into the outer box of the main body, and others that connected the main body and microphone with a cord.

The former has the inconvenience of having to bring the entire heavy and bulky device up to your mouth when making a call, and the latter has the inconvenience of frequent failures due to broken cords.

Publication of Utility Model Publication No. 51-904 proposed that the above-mentioned inconveniences of conventional devices could be resolved by properly using the microphone either directly attached to the device body or connected to the device body with a cord interposed between them. It is shown in the publication No.

In this proposal, the mechanical connection between the microphone and the main body of the device or the tip of the cord relies solely on the engagement of a plug and jack for electrical connection therebetween, so that the microphone is easily detached.

Therefore, the object of this invention is to ensure mechanical connection between the microphone and the main body of the device or the tip of the cord.

Hereinafter, this invention will be explained in detail with reference to illustrated embodiments.

In FIG. 1, 1 is a transmitter main body, and 2 is a microphone.

Inside the case 3 of the transmitter body, an antenna 4, a circuit board 5 on which necessary electric circuits are assembled, a power supply battery 6, a switch/output adjustment device 7, a level meter 8, etc. are housed.

Reference numeral 9 denotes an electrical connector, such as a jack, which is electrically connected to a predetermined location of the above-mentioned electric circuit, and a skirt-shaped receiving portion 11 is provided at the insertion port 10 of the electrical connector.

This receiving portion 11 is made integrally with the case 3 from synthetic resin, or is made independently from synthetic resin, and is fixed to the case 3.

The receiving part 11 is formed into a cylindrical shape so as to fit into a plug holder of a microphone, which will be described in the rear section, and has a protrusion 12 having some elasticity formed on its inner wall.

The protrusion 12 may be ring-shaped, or may be divided into one or several locations.

A screw receiver 1 is provided on the inner wall surface between the protrusion 12 and the insertion port 10.
3 is formed.

The microphone 2 includes a microphone body 14, an electrical connector directly connected to the microphone body 14, in this case a plug 15 that can be coupled to the above-mentioned jack, and a plug that holds this plug 15 and is mechanically coupled to the microphone body 14. It consists of a holding body 16.

The plug holder 16 is made of synthetic resin and is attached to the receiving part 1 of the transmitter body.
1, and a recessed groove 17 that engages with the protrusion of the receiving portion 11 is formed around it.

Also, the tip of the plug holder has a receiver 11 on the side of the transmitter body.
A screw 18 is formed which screws into the screw receiver 13 of.

When in use, the plaque holder 16 of the microphone 2 is pushed into the receiver 11 on the transmitter main body side.

As a result, the plug 15 is inserted into the jack 9, and the two are electrically connected.

Further, the concave groove 17 of the holder 16 engages with the protrusion 12 of the receiving part 11, and by further screwing the microphone 2, the two are screwed together by the screw 18 and the screw receiver 13.

In this case, as shown in an enlarged view in FIG. 2, the width of the concave groove 17 of the plug holder 16 is set to be wider than the protrusion 12 by the dimension necessary for the screw 18 to advance so that the microphone 2 can be screwed in. It is widely formed.

In the portable transmitter described above, since the microphone 2 is directly attached to the transmitter body 1, there is no disconnection of the connection cord as in conventional portable transmitters, and the transmitter can be used with peace of mind.

Another advantage is that if the microphone or the transmitter itself breaks down, the broken one can be easily replaced.

As mentioned above, this portable transmitter is characterized by the fact that the microphone is directly attached to the transmitter body, but if it is necessary to connect the microphone 2 to the transmitter body via a cord, For this purpose, a code having a structure as shown in FIG. 3 may be used.

That is, one end of the cord 19 is connected to the aforementioned jack 9.
A jack 20 similar to the above and a receiving part 21 having a similar shape to the receiving part 11 of the transmitter main body 1 are provided surrounding the jack 20.

A protrusion 22 and a screw receiver 23 are formed on this receiving portion 21, and the plug holder 16 of the microphone 2 is inserted into this receiving portion 21 and screwed.

At the other end of the cord 19 is a plug 24 similar to the plug 15 described above, and a plug holder 16 of the microphone 2.
A holder 25 having a similar shape is provided.

The holder 25 has a concave groove 25 that engages with the protrusion 12 formed on the receiver 11 of the transmitter body 1, and a screw 28 that engages with the screw receiver 13.

Even when connecting the microphone 2 to the transmitter body 1 via a cord with the above structure, it is extremely easy to replace the microphone and the transmitter body, and the cord itself is connected to the plug and jack connected to it. There are almost no disconnection accidents at the connections.

Note that if the microphone 2 is to be attached directly to the transmitter body 1 for a relatively long period of time, or if the cord 19 is to be interposed between the microphone 2 and the transmitter body 1, the microphone It is used by screwing the screw 18 on the side into the screw receivers 13 and 23 on the transmitter main body 1 side or the cord 19 side.

However, when the microphone 2 and the transmitter main body 1 are used by frequently changing the state in which they are connected directly or with the cord 19 interposed between them, the screw 18 is connected to the screw receiver 13.
It is sufficient to simply engage the concave groove 17 on the microphone side with the protrusions 12, 22 on the transmitter body 1 side or the cord 19 side without screwing into the transmitter body 23.

In general, plugs and jacks have a low mechanical connection strength because their purpose is simply to electrically connect a cord.

In particular, plugs with a small diameter are widely used as plugs for microphones, but such plugs have even lower mechanical bonding strength.

However, in this invention, when the microphone 2 is inserted into the receiving part 11 of the transmitter main body 1 or the receiving part 21 of the cord 19, the protrusions 12, 22 of the receiving parts 11, 21 are formed in the groove 17 on the microphone side. The screws 18 on the microphone side are inserted into the screw receivers 13 and 13 of the receivers 11 and 21 as necessary.
23, the mechanical bonding strength is high and it will not come off unnecessarily.

As a result, when using this invention, it is possible to improve the usability by appropriately using a usage mode in which a microphone is directly connected to an electronic device, a usage mode in which a cord is interposed in between, and a mode in which these two usage modes are frequently switched. Not only is this extremely convenient, but it also has the advantage that it does not become unusable even if the cord is broken, and that it is easy to replace the microphone if it breaks down.
