〔Example〕

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

FIG. 1 is a sectional view showing the internal structure of a handset according to an embodiment of the present invention, FIG. 2a is an external perspective view thereof, and FIG. 2b is an exploded perspective view thereof. In Figs. 1 and 2, 1 is the handset body, 2 is a transmitter, 3 is a transmitter holder, 4 is a receiver, 5 is a receiver holder, 6 is a handset cover, 7 is a screw, and 8 is a handset. 9 is a connector for connecting to the telephone main body, 6' is a convex portion for pressing the transmitter holder, and 6'' is a convex portion for pressing and fixing the receiver.

The transmitter 2 and the receiver 4 are respectively placed in the holder 3,
5 is fitted and inserted. The holders 3 and 5 are made of an elastic member so as to hold the transmitter 2 and the receiver 4 in close contact with each other. As shown in FIG. 1, the lower part of the holder 3 is shaped like a flap, and the tip thereof becomes the contact surface of the handset main body 1 where the transmitter is installed. The receiver 4 is also installed in the handset main body 1 via a holder 5 similarly made of an elastic material.

As mentioned above, since the transmitter 2 and handset 4 that use ceramic diaphragms are very lightweight, the handset itself is too light and difficult to handle (this is because the on-hook is incomplete due to the light weight). You may feel tired or feel unnatural when holding the handset. For this purpose, a weight 8 is placed approximately in the center of the handset. An engagement part for positioning the weight 8 is formed in the installation part of the weight 8 of the handset main body 1. In this way, the handset body 1 is connected to the transmitter 2,
A telephone receiver 4 and a weight 8 are placed.

In the above state, when the handset cover 6 is assembled to the handset main body 1, connected and fixed with screws 7, the handset is completed as shown in FIG. 2a. The handset cover 6 has convex portions 6, 6'', 6''' for press-fixing the transmitter holder 3, handset holder 5, and weight 8 when they are fixed to the handset main body 1 with screws 7. It is provided. That is, the handset cover 6 fixedly supports each component placed on the handset main body 1.

Next, the fixing structure of the transmitter 2 and the receiver 4 will be explained in more detail. 3a, b, and c are partially enlarged cross-sectional views of the fixed portion of the transmitter 2 in FIG. 1. In this figure, the same parts as in FIGS. 1 and 2 are given the same reference numerals.

In FIGS. 3a and 3b, the upper half of the transmitter holder 3 is a part that closely fits and holds the transmitter 2, and as shown in FIG. H
A shaped pressing portion 32' is integrally formed, and a flap-shaped portion is formed in the lower half. This holder 3
is made of an elastic member, and the bottom surface of the tip of the flap-shaped portion comes into surface contact with the area where the transmitter is installed on the inner surface of the handset main body 1. A fitting portion 31 is formed as an annular recess on the lower surface of this tip, and an annular projection 11 is formed on the side of the handset main body 1 with respect to this annular recess 31.

An annular projection 12 is formed on the handset main body 1 to support the upper end surface of the flap-shaped portion of the holder 3. The upper surface of this projection 12 abuts the upper end surface of the flap-shaped portion to raise the height of the flap-shaped portion. Define the This forms an air chamber for improving the acoustic characteristics of the transmitter 2.

Furthermore, a plurality of protrusions 13 are provided around these for supporting the H-shaped pressing portion 32' of the holder 3. A convex portion 6' of the handset cover 6 provided opposite to this protrusion 13 presses the pressing portion 32' to support the holder 3 so that it is not deformed by excessive force. The protrusions 11 and 12 provided on the handset main body 1 are connected to the holder 3.
The protrusions 13 are formed in four locations to correspond to the H-shaped pressing portions 32'.

In this way, the handset cover 6 is combined with the handset main body 1, and is fixed by the screws 7, and the holder 3 is pressed and fixed by the convex portion 6'. is not necessary.

Figure 3c shows another embodiment. The fitting part 31' provided on the lower surface of the lower end of the flap-like part of the holder 3 has a protruding shape, and correspondingly, two engagement protrusions 11 are provided on the handset main body 1 side. ', 12' are formed.

In this embodiment, the protrusion 13' for defining the height of the holder 3 and forming the air chamber constituted by the flap-shaped portion is only for supporting the H-shaped pressing portion 32'. The holder 3 is positioned and supported by the pressing force of the pressing part 6' of the handset cover 6, and the fitting part 31' of the flap-like part engages the engaging protrusions 11', 1.
2' and are tightly attached.

Next, the fixing structure of the receiver 4 will be explained with reference to an enlarged partial cross-sectional view of FIG. 4. In the same figure,
The same parts as in FIGS. 1 and 2 are given the same reference numerals. The handset 4 has a circular shape, and the handset holder 5 that tightly fits and holds the handset 4 has an annular shape. Unlike the handset holder 5, the handset holder 5 does not have a pressing part for receiving the pressing action of the protrusion 6'' of the handset cover 6. In other words, the protrusion 6'' directly presses the handset 4 to fix it. do. For this reason, the protrusion 6'' is configured in a simple plate shape, and is configured to apply a pressing force to the receiver 4 in a distributed manner.

Since the handset 4 does not require an air chamber like the transmitter 2, the holder 5 does not have a flap-like part, and simply attaches the handset 4 to the annular protrusion 14 formed on the handset body 1. They are simply fitted and placed and positioned. This handset holder 5
It is also made of an elastic member.

As mentioned above, the fixing structure of the handset 4 can be simplified because the handset 4 is only for outputting voice, and the transmitter 2 is sensitive to voice. If the handset cover 6 directly presses and fixes the transmitter 2, touch noise transmitted through the handset will be transmitted to the transmitter 2, and the intelligibility of the voice will deteriorate due to such noise being mixed in, which is not desirable. Not. For this reason, as explained with reference to FIG. 3, the fixing structure of the transmitter is designed so that the holder is provided with an independent pressing part so that the pressing force does not directly act on the transmitter. ing. However, the receiver can basically have the same fixed structure as the transmitter.

[Effect of idea]

As described above in detail, according to the present invention, the transmitter and receiver are fitted and held in a holder formed of an elastic member, and placed and positioned on the handset main body. By pressing and fixing with the convex portion, there is no need for conventional fixing fittings and screws, making it possible to significantly reduce the number of assembly steps. Therefore, the effect of contributing to lowering the price of telephones is extremely large.
