Abstract

The present invention serves to radiation protection of cellular phone users so that the speaker (24) and the microphone (25) are built in lateral, to the emitter (21) further side or emitter (21) or speaker (24) are built in special swivelling holders (27, 35 and 46) which rotated from folded position in ready to use position multiply distance between the user's head and the emitter (21). Removed speaker (24) and microphone (25) from the front side of the cellular phones (23, 26, 34 and 45) are leaving more space for better configuration of the screen and the buttons which can result in reduction of overall dimensions of aforesaid phones.

Description

CELLULAR PHONE WITH EMITTER DISTANT FROM THE USER DESCRIPTION OF THE INVENTION

1) TECHNICAL FIELD

The present invention relates to radiation protection of cellular phone users. Habit of users to touch the ear with the speaker part of the phone provides health risk with cellular phones because of the emitter closeness.

2) BACKGROUND ART

Emitters are mostly situated on the top of the phones near the speaker for better performance. Every new generation of the cellular phones comes tinnier what gets their emitter closer to the users body. Implementation of the various radiation protecting materials decreases emitting quality.

3) DISCLOSURE OF THE INVENTION

Primary task of the present invention is to keep cellular phone emitter distant from the user's head, while emitting, in order to decrease level of detrimental radiation.

Secondary task is to leave more space to the front side of the cellular phone for better configuration of the screen and the buttons.

Additional task is to decrease overall dimensions of the cellular phones while they are in stand by, passive position.

Radiation energy drops by cube of distance, for example: the closest part of the user's brain to the emitter shall receive thousand times less energy from the ten times more distant emitter.

Changing configuration of the cellular phone parts, according to one variation of the present invention, the speaker and the microphone are built in lateral, to the emitter further, side.

The other variations of the present invention are to place the emitter or the speaker in the special swiveling console holders which rotated in active position substantially multiply emitter's distance from user's head. 4) BRIEF DESCRIPTION OF THE DRAWINGS

Fig. 1 is showing diagram (20) of the radiation energy distribution, from the emitter (21) of the classic cellular phone (22), trough the brain of the user.

Fig. 2,3 and 4 are showing diagram (20) of radiation energy distribution, from the emitter (21) trough the brains of the users if they would be using some variations of the present invention.

VARIATION A)

Fig. 2 and 5 are showing one solution of the present invention i.e. the cellular phone (23) with the speaker (24) and the microphone (25) built in lateral, to the emitter (21) further, side.

VARIATION B)

Fig. 3,7,8,9,10,11 and 12 are showing second solution of the present invention where cellular phone

(26) with microphone (25) built in equally to variation A has the speaker (24) built in the bottom of the swiveling speaker holder (27). Front part (28) of the speaker holder (27) is connected to the back shell (31) of the cellular phone (26) in swivel joint by the ax (29) and the bearing (30). The ax (29) has opening (32) for the speaker wires and the elastic ring (33) prevents it of splitting from the bearing (30).

VARIATION C)

Fig. 4, 13,14,15,16 and 17 are showing third solution of the present invention where cellular phone

(34) with the speaker (24) built in equally to variation A has the emitter (21) clamped on the end of the swiveling emitter holder (35). Front part (36) of the emitter holder (35) is connected to the back shell (38) of the cellular phone (34) in the swivel joint by the ax (37) and the bearing (30). The ax

(37) has opening (32) for the emitter wires and the elastic ring (33) prevents it of splitting from the bearing (30). The microphone (25) of the very small cellular phone can be put closer to the mouth of the user by the tube (39). The tube (39) with the microphone (25) is connected to the back shell (38) of the cellular phone (34) in the swivel joint by the clamps (40 and 41) with the ax (42) and the bearing (30). The ax (42) has opening (32) for the microphone wires and the elastic ring (33) prevents it of splitting from the bearing (30). All aforesaid shells made of two parts may have the openings (44) for connecting screws.

VARIATION D)

Fig. 6 is showing fourth solution of the present invention where cellular phone (45) with the speaker

(24) and the microphone (25) built in equally to variation A has the emitter (21) built inside of the end of the swiveling emitter holder (46). Emitter holder (46) is connected to the shell of the cellular phone (45) same way as the emitter holder (35) of variation C.

5) APPLICABILITY OF THE PRESENT INVENTION

The best way to apply the present invention is to design new cellular phones implementing aforesaid solutions. Production of the cellular phones upon variation A should not be more expensive than production of the classic cellular phones. Production of the cellular phones upon other variants should be little bit more expensive particularly because mirror-symmetrical phones are to be built for left handed users, too. However, health benefit of the couple hundred time smaller radiation should encourage application of the present invention.

Various small improvements of the present invention are possible like installation of some springs for automatic opening of the said holders in operating position by push button as well as telescopic extension of the holders.

It is obvious that numerous modifications are possible without changing the idea or spirit of the present invention.
