Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an acoustic coupler for transmitting information via a telephone.

In recent years, since terminal devices using acoustic couplers can transmit information from any location as long as they have a telephone, there is a demand for acoustic couplers that are smaller and lighter in weight and suitable for carrying.
However, as shown in FIG. 1, in conventional acoustic couplers that are generally used, a control unit 2 is housed in a frame 1 formed in a chevron shape, and vibration isolating legs 3 are provided on the lower side of the frame 1. , the transmitter 5 of the telephone 4
The receiver 6 is placed across the frame 1. Therefore, it was large, heavy, and inconvenient to carry. Recently, in order to miniaturize acoustic couplers,
A device that is attached to a telephone transmitter is available for sending only. This method of attaching the telephone only to the transmitter lacks stability when the telephone is placed horizontally, and is susceptible to vibrations, which is the worst thing for acoustic couplers.

The purpose of the present invention is to eliminate the above-mentioned drawbacks of the conventional technology by making it smaller and lighter, making it more convenient to carry, and improving stability and anti-vibration properties. An object of the present invention is to provide an acoustic coupler that can improve sensitivity and the like.

In order to achieve the above object, the present invention houses an acoustoelectric transducer in a housing, forms a fitting part in the housing to fit into a telephone receiver, and provides anti-vibration legs on the outside of the housing. A receiving acoustic coupler and an electroacoustic transducer are housed in the housing, a fitting part is formed in the housing to fit into the transmitter of the telephone, and vibration isolating legs are provided on the outside of the housing. The fitting portions of the receiving and transmitting acoustic couplers are fitted to the handset and transmitter of the telephone, respectively, and the anti-vibration legs of the receiving and transmitting acoustic couplers are fitted with the telephone set horizontally. The device is characterized in that it is configured so that the

The present invention will be described below along with one embodiment thereof. As shown in FIG. 2, this acoustic coupler is composed of a transmitting acoustic coupler 10 and a receiving acoustic coupler 11. The transmitting acoustic coupler 10 is the third
As shown in the figure, an electroacoustic transducer, for example a speaker 13, is housed in a housing 12 made of an elastic material such as rubber. The housing 12 has a peripheral wall 14 formed in a cylindrical shape.
A partition wall 15 and an annular rib 16 are integrally provided with a slight interval between them at the inner middle part of the partition wall 15, and a plurality of holes 17 are formed in the partition wall 15. A fitting part 18 is formed on one side of the peripheral wall 14, and the fitting part 18 has a diameter that gradually decreases from the open end toward the partition wall 15 so that it can fit into the transmitter 20 of the telephone 19. is formed. The other side of the peripheral wall 14 is closed by an end wall 21. Anti-vibration legs 22 made of an elastic material such as rubber are integrally protruded from the outer periphery of both ends of the peripheral wall 14, and these legs 22 are formed to have substantially the same height. The outer periphery of the end of the speaker 13 is held between the partition wall 15 and the annular rib 16 of the housing 12, and the cord 23 connected to the speaker 13 is inserted through the hole 24 formed in the center of the end wall 21. being guided by someone.

The reception acoustic coupler 11 has an acoustoelectric transducer, for example, a carbon microphone (not shown) in a housing 12 formed in the same manner as the transmission acoustic coupler 10 described above.
is stored.

To use the acoustic coupler of the present invention, the fitting portion 18 of the transmitting acoustic coupler 10 and the fitting portion of the receiving acoustic coupler 11 are fitted to the transmitter 20 and receiver 25 of the telephone 19, respectively, and the telephone 19 is placed horizontally, and the vibration-proofing legs 22 of both acoustic couplers 10 and 11 are placed on the placement surface 26. At this time, the peripheral wall 14 of the housing 12 is formed into a cylindrical shape as in the above embodiment, and the peripheral wall 14 is formed into a cylindrical shape.
If the anti-vibration legs 22 are provided on the outer periphery of the telephone 19, the acoustic couplers 10 and 11 can be connected to the transmitter of the telephone 19 and the receiver 2
0, 25 can be placed in a stable state without paying attention to the directionality when fitting.

Note that the peripheral wall 14 of the casing 12 may be formed into a so-called drum shape with an inwardly recessed intermediate portion, and vibration-isolating legs may be formed on both sides, or only the vibration-isolating legs may be made of elastic material. It may be made of material. In addition, the present invention can be modified in various ways without departing from its basic technical concept.

As is clear from the above description, according to the present invention, the fitting portions of the transmitting and receiving acoustic couplers are fitted to the transmitter and receiver of the telephone independently, so that the acoustic coupler It can be made smaller and lighter, making it easier to carry. In addition, according to the present invention, since the housing is formed into a cylindrical shape and the ring-shaped vibration-proof legs are formed on the outer periphery of the housing, the transmitter,
Even when it is fitted to the handset, there is no directionality in the fitting, it can be fitted in any direction, and it is extremely easy to fit, and the legs do not function as legs even when fitted in any direction. This has the advantage that a telephone or the like can be easily and stably supported horizontally. Further, according to the present invention, since the telephone set is placed horizontally, it is possible to obtain an advantageous posture in terms of the sensitivity of the telephone set, the distortion rate of the transducer, such as a carbon microphone, etc.
