DE19616867A1 - Telephone with detachable earpiece and mouthpiece - Google Patents

Abstract

The telephone (1) or digital telephone equipment has an earpiece (5) or loudspeaker and a mouthpiece (6) or microphone, which are both mechanically separable from the handset (2). When the user requires hands-free communication the telephone can become an ordinary mobile telephone, by detaching the earpiece and holding it to the head by hand. In other circumstances or according to need, the user can press the key (3) to remove the holder, with the mouthpiece and the earpiece, from the telephone, but keep them still connected to the telephone by a cable (4).

Description

1. Problems 1.1 Harassment

For telephone calls, either the handset of a classic (with a cord or the Handy, the mobile radio telephone, the cordless handset can be held directly on the head, or that Telephone calls must be switched loudly (as previously called "hands-free"), so what can be done comes out of the loudspeaker, but is undesirably listened to by other people in the area. This is particularly annoying when the interlocutor deals with hand (hands), or dangerous if the other party drives a car.

1.2 Health damage

Although it is still controversial today, it is more and more likely that one with cordless phones, cell phones, radio equipment brain tumor, sleep, dream, memory disorder but we should also think about whether it may be true or the Damage could not be neglected. Let's take preventive measures from the beginning before we notice and can clearly, visibly demonstrate that it is true and already too late. But this is about Human life.

2. Goals

Let us facilitate further statements, explanations with the following agreements:

• 1. By a telecommunications device, abbreviation DiT device, we mean a device with which one person can communicate with another directly and from a distance (relative term). The are, for example, telephone sets with and without a cord, mobile radio telephones, cell phones, radio devices alone or with others such as answering machine, fax machine. . . integrated.
• 2. By a personal phone call we mean a phone call that is from nearby other people can not be heard officially, what from the speaker one Di-telecommunication device (DiT device) comes. It's like a hands-free conversation today not personally with our agreement.

Our goals are:

• 2.1 New di-telecommunications device, in which you can use the classic handset (if he is not cordless), not in his hand and not on his head (if he is cordless or a cell phone) must hold and the phone call is personal.
• 2.2 Measures against suspected by cordless phones (electromagnetic field energy) create health damage caused in 1.2.
• 2.3 However, the solutions should be inexpensive. We are not allowed to use an extra speaker or microphone to use.
• 2.4 The handy properties, especially with mobile radio telephones, must not be cordless going to lose. This means that no additional external device (s) (e.g. extra headphones, antenna...) be used for our purposes.
• 2.5 The user, and therefore the manufacturer, wanted to go one step further for health we have another thought and prevention that the DiT device is the part of the body where the device is close (Breast pocket, trouser pocket...), Not harmful.

3. Solutions

There are several solutions to our problems. According to our goals, here are just a few Main solutions presented that are independent of each other. Manufacturers and users have the choice with which solution to eliminate the above problems or be satisfied.  

Note 1

The proposed devices, possibilities in the following sections, in each Individual images of the images do not all have to be present in a implemented DiT device. By Combinations of these individual components, we have different variants for devices our solutions.

3.a Mechanical coupling and uncoupling Note 2

The following applies to all the next proposed mechanical couplings and decouplings common remarks:

• - Electrical connections are continuously maintained when connecting and disconnecting.
• - The coupling and uncoupling can be done from the inside, outside or from the back or from the side (top, below, right and left) from a DiT device and combinations thereof.

We have two main solutions for mechanical coupling and uncoupling.

3.a.1 The first solution

DiT device with loudspeaker mechanically separable from the device and separable Microphone.

Similarity in picture 1,. . ., 6

Let us look at the pictures 1 to 6. In the pictures we see DiT devices which have mechanically separable loudspeakers 5 and separable microphone 6 , which hold together with a suitably shaped, constructed holder 2 . If the user does not want to or if it is not necessary (e.g. during short conversations, the hand is free or the damage to health is unimportant to him ...), the user can continue to this day (device, handset on the hand Holding head) on the phone. For some reason or if necessary, the user may e.g. B. by a confirmation (please see note 3.4) on the device 3 to mechanically decouple the holder 2 (and thus also the loudspeaker and the microphone) from the device 1 (or the listener). We see this coupling in the pictures. He places the holder 2 on the ear or near the mouth. The connecting cable 4 , which holds the electrical connection between the microphone and the loudspeaker from the holder to the DiT device 1 during the coupling and uncoupling of the holder, which we repeatedly emphasize the coupling and uncoupling of the microphone and the loudspeaker purely mechanically to have. The cable can with a (spiral) spring after the conversation when coupling or coupling the holder in or to the device 1 in the original state z. B. automatically withdraw by confirmation on the device 3 . The device 1 in the pictures, the user after disconnection during a phone call on the table, in his pocket. . . lay.

Note 3

As above, we also have several variants, details that are important for a realization may be. For example:

• 3.1 The cable 4 should be sufficiently stable so that when the cable is pulled out or when the cable rewinds itself after a long time, the electrical cable connection must not be interrupted or torn by the cable. That can e.g. B. can be achieved with a thin reinforcement rope (s). The protective effect can be increased if the reinforcement rope (s) is (are) somewhat but significantly shorter than the electrical lines.
• 3.2 It is important for our devices in this section: the holder 2 must lie or sit correctly on the head (or on the ear, near the mouth). At first glance, this naturally depends on the shape of the holder. However, we can achieve the desired position of the holder if we pay attention not only to the shape but also to the position of its center of gravity, and the position of the center of gravity depends not only on the shape but also on the inhomogeneity of the holder material. With a correct weight distribution due to the inhomogeneity, we can achieve the most beautiful shape with the correct seat of the holder.
• 3.3 When designing, we have to make sure that such a holder is firm, stable on the desired one Position (on the ear, head) should remain. It must not slide undesirably from the position or fall out, but which may put the user in a dangerous situation (e.g. especially while driving) could. In addition to Note 3.2, we can increase the secure fit of the holder by using the Surface adhesion: surface properties and / or elasticity in part (instead of in part we can refer to the whole holder, but what should not be due to unnecessarily high effort) of the holder accordingly.  
• - Surface property: opt for the adhesion of the surface of an object here the holder roughly two factors are the shape, the type or the profile of the surface and the material of the surface of the object.
• - Elasticity: (Part of) the holder (s) 2 is elastic, which we can see as an example in Figures 2, 6. Due to the elasticity or the back force, the holder sits fairly firmly in the desired position.
• 3.4 The space (unit) vector represents the direction of confirmation represents, where is. This makes confirmation like pushing and printing are special cases: x, y, z independent of parameter t. When turning is confirmed the vector is therefore dependent on the parameter t.

Image 1: There are numerous variants of how the holder 2 looks. In the picture we see an example. About the "joint" or device 10 6. crosstalk in the picture 4, the "reader" 7 we find the application in the work under number G 295 15 850.6. The holder can also be coupled from or to the DiT device 1 by means of a confirmation on the device 3 . The device 3 in the picture and all pictures can be in a different position on the DiT device.

Figure 2: As we have already talked about a possible elasticity (in part) of the holder in remark 3.3, the holder 2 can, as indicated in the picture with the double arrow w₂, have a tight fit. If the seat is stable enough, the additional adhesion due to the holder surface is superfluous. The double arrow w₁ indicates that the microphone 6 can be pulled out and back, which with its small sensitivity or in a noisy environment (on the street, at the train station) allows the microphone a little closer to the mouth. If the sensitivity of the microphone, the noise attenuation of the DiT device is good enough, we do not need such a possibility (w₁).

Figure 3 shows us the coupling, decoupling of the holder 2 from the back at I, II or from the inside at III. The machine code output can be found in work G 295 15 850.6.

Figure 4 shows us some other variants. With appropriate constructions, the holder 2 can be mechanically coupled or uncoupled in part or entirely from the side to or from the device. In the picture we see the "joint" again, which enables the movement w₁.

Figure 5 shows us as an example the connection and disconnection of the holder 2 from the inside of a hinged mobile phone.

Figure 6: A variant of Figure 5: the coupling and decoupling are done from the outside. The user does not need to open the phone when there is an incoming call. In the picture a variant of the movement w₁ (comparison picture 2, picture 4) is shown.

3.a.2 The second solution

DiT device with loudspeaker that can be mechanically separated from the device.

This solution is not optimal. It is only given because of the different views of the users. It is similar to the first solution. Instead of both: loudspeaker and microphone as above, only the loudspeaker of a DiT device is mechanically decoupled from the device by confirmation. The handset or the device can be with a or a small (possibly hinged) hook or clamp 8 z. B. be held on clothing. The solution is fairly simple than the last one, but it has a disadvantage, particularly in the case of mobile flash telephones, that the DiT device is close to the heart (influence of electromagnetic waves on the heart) of the user. Since the microphone is still in the device, the device must not be too far from the mouth when talking. If we combine this with another proposal in section 3.b, we can overcome the disadvantage. We discuss this in section 3.c. Another disadvantage (?): The microphone should have a certain sensitivity, but this is already the case with today's hands-free telephone set.

Pictures 7 and 8 show us similar to the last pictures. Here only the loudspeaker is mechanically connected and disconnected, which holds the ear with the holder 2 . In Figure 7, the holder is connected and disconnected from the inside, in Figure 8 from above. However, as noted above, it can be on the side or rear. . . happen.

Figure 9 shows us a variant for hinged DiT devices. So that the user does not have to open the device when there is an incoming call, the (additional) opening for the microphone (not only internally) should be directed outwards as 2 a or 2 b.

3.b- shielding Shielding only

In this section we wanted to suggest other solutions. It has long been known to us from the literature that electromagnetic waves can be shielded by a network of electrically conductive material. Let us use these properties to solve our problem 1.2. So with the suggestion in this section alone, we are only solving problem 1.2. Depending on the reception sensitivity of the DiT device, the shielding efficiency of the form (visible 12 or Mo and invisible (root of the shield) Mu in Fig. 10, 11), the side effects (wave reflection, absorption ...) of the shield we also have numerous variants regarding the shape of the shield. Figures 10, 13 show us some variants, which are drawn here as an example due to the large number possible.

Fig. 10: When the device 3 is confirmed, the shield 12 goes out of the (opened) opening 11 , which, by means of the corresponding construction, spans itself. The shield thus prevents the propagation of the electromagnetic waves towards the user's head. After use, the shield can be pulled back into the device. A network as in the picture does not have to be used for the shielding. It can be a (thin, shaped) plate, a foil. . . be what the electromagnetic wave does not let through.

Figure 11 shows us a variant for the shielding. With the device 12 we want to prevent the spread of the electromagnetic wave in the direction of the head. The possible movement (see remark 1) w makes it possible, if necessary (e.g. weak signals, operating energy... During a short conversation or short use), to clear the shield by means of a confirmation on the device 3 (e.g. pull into the device, fold up...). The drawings 12 d: top view, 12 v: front view, 12 s: side view of the shield 12 show us in somewhat more detail. By changing the data r _i for i = 1,. . . 6, a, b, c, e, f, g and α we have different shapes for the shield 12 . In Figure 11 r₃ = r₄ = 0. Some examples of the variation using the top view 12 d, with which we can derive the corresponding front view and side view, are shown in Figure 12.

If necessary, we can extend the shielding into the device, which we indicate with the drawing Mu. Mo in the picture indicates part 12 .

Figure 12: Drawing 1 is a repetition of 12 d in Figure 11. Let's change the parameters r _i for i = 1,. . . , 6, a, b, c, e, f; g and α we have the drawings 2 ,. . ., 9 as well as I and II in picture 13. A is the top view of antenna 9 in other pictures. In plan view 6 , 7 , 8 , 9 , the shield is part of the jacket of antenna A. With a coating ü (drawing 9 ) on the antenna and the shield, our DiT device looks exactly like a current DiT device from the outside .

Figure 13 shows us further variants for the shield 12 or Mo in Figure 11. The possible movement w makes it possible to clear the shield 12 if necessary.

3.c combinations

Our DiT devices are a little more complex but more comfortable and effective if we have the solutions 3.a. and 3.b combine. The user has the choice depending on his situation at the time of use, which device (s) he wants to use.

The studies published to date (and some unpublished ones) indicated that electromagnetic waves predominantly affect the brain, the nerve cells and thus cause the damage, problems as described in section 1.2. But let's go one step further: further prevention (whether it is superfluous?), Especially for users who often use their cell phones for a long time, that possible (considerable?) Damage to cells, tissues (skin, muscles, bones. .) could arise where the DiT device lies on the body during the conversation according to the suggestions in sections 3.a and 3.b. Our DiT devices are constructed in combination according to a proposal in section 3. a and a proposal in section 3.b.

4. Review and achieved benefits

Now let's see if our solutions meet our expectations:

• - With our di-telecommunication device, a user can communicate as usual until today (with hand, head ... if, for example, he has a free hand or health damage is unimportant to him ...). If necessary z. B. free hands needed to keep the device or the handset away from the head, the user needs to confirm the decoupling device in order to free hands for other activities (writing, scrolling, typing, carrying a case, both hands on the steering wheel or that Keep the DiT device away from your head (health precaution, etc.). Or with the shielding (with or without Mu in Figure 11) the bad influence of the electromagnetic wave on the health of the user can be prevented.
• - With our suggestions we do not need any additional headphones, speakers or anything else Microphone, which can be expensive with good quality. No additional antenna etc. and therefore the The handiness of our DiT device does not work with our proposals in comparison with today's to lose.
