affect one or more listeners.

With ordinary telephone sets, only one person can use the set and hear with only one ear, so that with the other ear he or she has to accept any noise in the environment; Therefore, additional microphones, amplifiers or similar devices must for certain requirements, contact connected, so several people can listen while other ^T must be taken rkehrungen) so that the error "cloth the noise of the environment is reduced; ee BPST therefore not hen slightly KU corrective defects, as long as complex auxiliary devices are not used, which require a modification of the conventional systems, which are often still not effective.

The present hiring has therefore set itself the goal of creating a device for taking long-distance calls which is extremely simple, compact and very economical and which allows the user to listen in on both ears or by several people without having to use the existing one Plant changes need to be made. The device can be attached directly to the usual handset by applying pressure.

show in the attached drawing:

Pig. 1 the device according to the innovation in section according to a ^ Line H-II of the Pig. 2;

Pig. 2 shows the same device in section along a line III-III through the Pig. I ₅

Pig. 3 again the same device according to FIG. 1, seen from below.

Sin device according to the Pig. 1, 2 and 3 has a first can-like body 2, which by means of a hose line 1 (for example made of plastic or rubber) is connected to a second socket housing 5.

The can body 2 has a shell-like shape and the earpiece of an ordinary telephone receiver (partially indicated by dashed lines in FIG. 1 ) can be inserted into the same with slight friction. In the middle of the bottom 10 of this housing 2, a cylindrical wall 3 is formed or attached, which is connected to a lateral opening 4, into which one end of the hose line 1 is pushed.

At the bottom of the mouthpiece % there is a view on the bottom 10). Drilling

12Α provided.

The can body 5 is at the top and bottom by means of the bottoms 6 and 7 covered. On the bottom 7 a recess open to the outside of the can body is provided, which at least? is limited by a wall in which the bore 9 is arranged, into which the other end of the hose line 1 is used.

The can-like body 2 can be easily adapted to any telephone receiver if its edge with Radialsohlxtzen 11 is provided, which is the correct extension to adapt to the riser knife of the earpiece allow, the can body 2 is held elastically on the receiver.

In addition, according to the innovation, a ring 12 is made of an expandable material provided, which serves as an adjustment organ and which can be easily aligned or moved, to adapt the can body 2 to the earpieces of different diameters.

The operation of the renewal contemporary device is obvious from the above, and may price as follows be summarized:

When the can body 2 is attached to the receiver due to the elastic deformation of the edge provided with slots 11 is, with or intermediate layers of the elastic ring 12A, the sound energy flows from the listener through the recesses 12A, both through the cylindrical wall 5 as also through the hose line 1 to the niche 8; the from Sound coming from the telephone receiver is therefore both at the bottom of the can body 2 and at the bathing of the can body 5 audible so that the user has the option of either using both ears or a second person to hear to listen in. It is obvious that for listening in to several people, the corresponding box housing of training 5 must be provided in larger numbers. In this case, the can housing to the can body 2 by means of several hose lines of the type described or by means of corresponding Branch organs of connected hoses are connected.
