Abstract

PURPOSE: A reception and transmission separation type radio earphone is provided to improve a transmission and reception function in a telephone by using a radio transmission and reception earphone. CONSTITUTION: A reception and transmission separation type radio earphone comprises a telephone portion(1), a transmission portion(2), a reception portion(3), and a wire main body portion(4). The telephone portion is communicated with the wire main body portion. The transmission portion transmits a sound transferred from the telephone portion to the reception portion. The reception portion receives the transferred sound from the transmission portion.

Description

Codeless earphone separated between receiver and sender}

In the use of the telephone which is most used in real life, earphones are useful as an alternative article to solve the inconvenience of carrying a handset and a telephone.

Existing earphones solve the data transmission with the main body by wires, and this connection wire is twisting the wire and the earphone is easily disengaged from the ear, which hinders the popular use of the earphone.

In order to solve this problem, it is possible to eliminate the connection line by using wireless communication, which has been widely used. Since the price, performance, and components have been greatly developed, the technology for applying to earphones is dependent on the choice and methodology, but there is no problem at all. to be.

However, a relatively large amount of power is required compared to a wired line. In the case of earphones, large batteries cannot be used due to the characteristics that must be attached to the ear, and earphones cannot be used wirelessly until a new large capacity battery is developed in the future.

In the wireless earphone, the problem that the large battery necessary for the transmission and reception with the main body cannot be attached to the ear together with the earphone is solved, and a separate wireless communication method suitable for the earphone function is explored.

In order to solve the problem that the large battery cannot be attached to the ear together with the earphone, the receiver and the transmitter of the earphone which are used as a single body are separated, and each power supply is also separated, and the small battery is required for the receiver that requires only a small amount of power. There is no problem in attaching to the ear using the transmitter, and the transmitter that requires a large amount of power for wireless communication wirelessly processes a certain distance by using a high-performance microphone, and the microphone and the telephone are treated as a short distance line through the earphone port. Eliminate the power supply you need.

In addition, in this form, for wireless communication with the main body, the receiver of the earphone uses the FM or RF frequency and infrared method transmitted from the main body, and the transmitter of the earphone uses a high sensitivity microphone.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a configuration for transmitting and receiving wireless earphones. As shown therein, the telephone section 1;

As a mobile communication terminal (cell phone) or a wireless telephone that performs all telephone functions, the wireless telephone communicates with the wired main unit 4 using a frequency such as 900 MHz.

A transmitter 2;

It performs the same earphone transmission function as the transmitter of the telephone by using a high function microphone, and transmits the sound transmitted from the telephone unit 1 to the receiver 3. It may be connected through the earphone port of the phone unit 1, or may be embedded in the phone. When connected from the outside through the earphone port, the power transmitted from the phone unit 1 is used as its power source. At this time, if the power is not enough to use, the necessary power is made through the boosting process using the internal circuit. It may also be provided with a power supply port for the receiver for recharging the battery used in the receiver (3).

A receiving unit 3;

Performs the same earphone reception function as the receiver of the telephone, and receives the sound sent from the transmitter (2). The power supply is used by attaching a small battery, and may use a power supply port for a receiver provided in the transmitter 2 for recharging.

Wired body portion 4;

When the telephone unit 1 is a wireless telephone, it performs the main body function of the wireless telephone with a telephone line.
