Abstract

The present invention discloses an acoustic tubular portable telephone.

The present invention forms a collapsible or retractable sound tube in a telephone body in a known portable wireless telephone, so that it can be hydrated by connecting an acoustic tube to a receiver hole of the receiver when using the portable radio telephone. By creating a distance between the sender and the user's brain, the radio wave generated when making a call has less effect on the user's brain.

Description

Sound Tube Portable Cordless Phone

When the conventional portable radiotelephone is used, the main body is in close contact with the ear so that the core radio wave emitter emits radio waves in close proximity to the user's brain, and there is a concern that the radio wave is harmful to the user's brain.

Until now, in order to reduce the concerns about the radio wave hazards of consumers, it is possible to reduce the intensity of outgoing radio waves by improving the radio receiver's output through electronic technology development, and to reduce the intensity of outgoing radio waves and to improve the case material of the portable radio telephones. Although the performance is being improved, there is a problem to increase the initial ringing sensitivity of the antenna in order to increase the electromagnetic wave effect and the call success rate by the exposure of the antenna.

The present invention was devised to remarkably improve the conventional electromagnetic hazard problem as described above, so that it is possible to use the portable cordless phone in the normal use state while talking on the portable cordless phone, without disturbing the call sound quality. The main focus is to leave a space between the core radio transmitter of the telephone body and the user's brain and to receive a call sound. By allowing the distance between the portable radiotelephone and the user's brain, the effect is significantly reduced.

Such a characteristic configuration and the effects of the present invention will be more apparent through the detailed description of the invention with reference to the accompanying drawings to be described later.

As illustrated in Figs. 1A and 1B, the telephone main body 1 has a telephone receiver 2 at one end thereof, a dial button 3 is disposed at the upper end thereof, and a sign language window 5 is installed at the upper end thereof. A retractable protective cover in which a connecting lever 12 is protruded in a conventional portable radiotelephone having a sign language speaker 6 inside thereof as shown in FIG. 1C and an antenna 11 for transmitting and receiving formed thereon. 10) is formed, the pivot shaft 13 is formed on the side of the hydration window 5 so that the opening and closing direction can be opened in the direction of the hydration window 5, both ends are open to the retractable protective cover 10 as shown in Figure 1c. A hollow acoustic tube 8 is formed, and the receiving window 9 for transmitting a sound directly to the ear is formed at the end of the acoustic window 7 and the protective cover 10, which are windows opened toward the lever 12.

In use, as shown in FIG. 1D, when the protective cover 10 is opened at an obtuse angle, the acoustic window 7 covers the sign language window 5 formed on the front of the speaker 6, so that the call of the speaker 6 is stopped. After passing through the sound tube 8 again through the receiving window 5 and the sound window 7 is passed through the receiving window 9 to the ear.

As illustrated in FIG. 1E, when the portable radiotelephone is used, the main body 1 of the user's brain is used at a position separated by the acoustic tube 8, so that electromagnetic waves generated at the core radio wave transmitter of the portable radiotelephone are used. Effect on the brain portion of the user is significantly reduced.

FIG. 2a shows a case in which the speaker 6 is directly mounted on the acoustic tube 8 of the protective cover 10. The speaker 6 for the sign language is placed on the acoustic window 7 in detail according to FIG. 2b. By directly assembling the fixing plate 14 and the fastening screw 15, the sound of the speaker 6 for receiving is directly heard through the sound tube 8 and the receiving window 9.

2c illustrates that the protective cover 10 having the speaker 6 mounted thereon is assembled to the main body 1, and the acoustic tube 8 has the capability of reducing electromagnetic interference of the present invention as described above.

3A shows a case in which the acoustic tube is formed in the collapsible receiving tube 17, which will be described in detail in FIG. 3 (B) as a perspective view of the folded receiver tube 17. A sound window 7 is formed, and the speaker 6 is fastened with a screw 15 so that the call sound of the speaker 6 is received through the sound window 7 and the sound tube 8 formed in the receiver tube 16. You will hear through).

The receiver tube 16 is inserted between the front cover 4 and the rear cover 17 to be assembled by fastening with screws 18.

The receiving tube 16 is used at an obtuse angle when used, and the electromagnetic wave effect is reduced when the portable tube is used by the receiving tube 16.

As described above, the acoustic tubular portable telephone according to the present invention has a maximum distance from the user's brain when using so that the user's brain receives less influence from radio waves generated from the portable wireless telephone, thereby significantly reducing the possibility of radio wave pollution. It is effective in reducing
