Abstract

PURPOSE:To couple a handset to an acoustic coupler independently of the shape of the handset by providing an elastic belt coupling under pressure the handset of a telephone set to an acoustic coupler main body to a data communication terminal device incorporated in the sound coupler. CONSTITUTION:The coupler main body 6 is arranged on both ends of a rear face 5a of the terminal device 5, and a hook 7 and the elastic belt 8 are arranged on the middle part. A mounting member 9 having two hook hole parts 9a, 9b is arranged on the tip of the belt 8. The inner diameter of a cup of the coupler main body 6 is increased more than the outermost diameter of the handset (circle type and square type). The belt 8 is wound around the middle part of the handset 12 while the handsets 12a, 12b are brought into contact with the inside of the cups 6a, 6b and any of the hook holes 9a, 9b of the belt 8 is locked to a hook 7. Since the handset 12 is mounted laterally, the transmission performance because of kinds of microphones is not deteriorated in this case. When no acoustic coupler is used, the belt 8 is accommodated in the device 5 through a storage hole 10.

Description

[Detailed Description of the Invention] Industrial Field of Application This invention provides acoustic coupling with the transmitter/receiver section of a subscriber telephone.
This relates to an acoustic coupler that transmits and receives data.

Conventional configurations and their problems In recent years, acoustic couplers have often been built into data communication terminal devices (hereinafter referred to as terminal devices).

For example, FIGS. 1 and 2 show a conventional terminal device with a built-in acoustic coupler, where ] is the terminal device main body and the two-digit acoustic coupler main body. This acoustic coupler main body 2Fi telephone is arranged so that it can be fitted and coupled in a Kasuri-oriented position N (a state in which the transmitting/receiving surface faces downward), and the shape of the cup is round. This is another example of the 3u terminal device main body shown in FIG. 2, and the shape of the acoustic coupler main body 40 cup is round.
It is placed on the side of the This is because if the microphone built into the transmitting section is made of recycled powder, it is better in terms of transmission performance to use the transmitter/receiver section of the phone horizontally rather than facing downwards. In FIG. 1, a telephone (not shown) with a round transmitter/receiver part is fitted into the circular recesses 2a and 2b of the acoustic coupler body 2, and in FIG. (not shown) are fitted into the circular recesses 4a, 4b of the acoustic coupler body 4 from the sides.

However, these acoustic couplers are only used in telephones with circular transmitting and receiving parts, and in square telephones, an armpit is created between the circular four parts 2a and 2b, reducing data transmission and reception performance. There was a drawback.

Purpose of the Invention The present invention solves the above-mentioned conventional drawbacks, and allows a telephone to be press-connected to an acoustic coupler regardless of the shape of the transmitting/receiving part of the telephone (circular or square). The purpose of this invention is to provide an acoustic coupler whose transmission performance does not deteriorate even when used with a telephone.

Structure of the Invention The present invention includes an acoustic coupler body and an elastic belt for pressure-bonding a telephone to the acoustic coupler body. ), and the elastic belt allows any telephone to be pressure-connected to the acoustic coupler with a constant force, thereby maintaining stable transmission performance.

DESCRIPTION OF THE EMBODIMENTS A terminal device incorporating an acoustic coupler according to an embodiment of the present invention is shown in FIGS. 3 to 5. That is, it is a 5-digit terminal device main body, after which a turnip 2 main body 6 is arranged at both ends of a back surface 5a, and a hook 7 and an elastic belt 8 are respectively arranged in the center thereof. There are two hook holes 9a at the tip of the elastic belt 8.

A mounting member 9 having 9b is arranged. This is a stopper that is placed at the rear end of the 11-degree elastic belt 8 in the storage hole for storing the 1-degree elastic belt 8 and restricts the forward movement of the elastic belt 8.

With the transmitting/receiving parts 12a and 12b of the telephone 12 placed sideways, the elastic belt 8 is placed in a state where the transmitting/receiving parts 12a and 12b are placed lightly against the inside of the cups 6a and 6b of the acoustic coupler main body 6, and the elastic belt 8 is placed sideways.
, 12b, one of the hook holes 9a and 9b of the attachment member 9 at the tip of the elastic belt 8 is hooked to the hook 7. At this time, the telephone 12 and the acoustic coupler main body 6 are mechanically connected to each other by pressure due to the rolling force of the tensioned elastic belt 8. In particular, the transmitter/receiver section 12a
, The distance between the transmitting/receiving surface and the grip part may be different depending on whether the shape of the belt 12b is circular or square. Therefore, when the elastic belt 8 has a certain length, there is a difference in the pressure bonding force with the acoustic coupler main body 6. Moreover, the transmission performance also fluctuates. In this case, by properly using the hook holes 9a and 9b, the pressure bonding force of the telephone 12 can be kept constant. Furthermore, when the acoustic coupler is not in use, it can be moved and stored inside the terminal device main body 5 through the elastic belt 8t/i and the storage hole 10, so that the space in which the terminal device main body 5 is placed can be narrowed.

Further, a transmitting/receiving section 12a.

32b can be placed sideways, so the transmission performance will not deteriorate depending on the type of microphone.

It is needless to say that the acoustic coupler and transmitting/receiving section of the present invention can be mounted vertically.

Effects of the Invention As described above, the present invention has the effect that, regardless of the shape of the telephone, it can be connected to a telephone without deteriorating transmission performance.
