Abstract

Mobile phones are everyday portables, and players such as CD players are also portable.

In general, portable devices such as a tape recorder, a small radio, and an MP3 player are mostly played in a stereo format. (Hereinafter, these portable devices are called players).

If you are listening to music while listening to music while playing with your phone and player at the same time, unplug the player's earphones and turn on the phone to make a call. This is due to the incompatibility between the earphones of the player and the earphones of the mobile phone. For the purpose of solving this inconvenience, the present invention uses the present invention with a built-in microphone as a repeater to connect the mobile phone to the player while listening to music while using stereo earphones in common. It detects the incoming call, generates a ringtone in the earphone, and connects the signal from the player to the mobile phone by pressing the switch installed in the present invention so that the user can talk on the phone without removing the earphone. Be sure to

Description

Hands-free device which can answer call during music listening {hands free for music player}

In the prior art, the player and the mobile phone are mutually independent devices, and the stereo earphones must be used to listen to the sound emitted from the player, and the mobile phone can be turned on or the microphone and earphones for mobile phones are integrated. It could not be mixed. That is, when a call was received while listening to music, the user was able to make a phone call by stopping the music listening and turning on the phone. When the call was over, the user had to hang up again and use the earphone of the player.

The mobile phone checks the signal calling itself from the surrounding signals from time to time, and when a signal calling its own signal is received, it outputs a response signal. The radio wave detection circuit 21 detects this. As shown in Fig. 2, in the main body 20 having a radio wave detection circuit 21 and a ringer generator 22 which can know that a call has been received, the earphone 27 is normally connected to the player, so that music listening is possible. Technology that detects incoming calls when possible and generates ringtones for the earphones you are listening to,

When the call comes in, the contact is changed by pressing the switch 24 once, so that the earphone 27 is switched from the output of the player 6 to the output signal of the mobile phone 5, and at the same time, the switch 26 connected to the microphone signal line is 1. Technology that allows you to answer a phone call twice.

The technique of extending the line of the antenna from the main body (2) in order to increase the sensitivity of the radio wave detection circuit (21) and attaching a ring (29) at the end thereof so as to easily install in the mobile phone (29).

The earphone jack installed in the mobile phone 5 has a structure in which the microphone signal and the earphone signal are output at the same time, and when the call comes in, the microphone signal and the ground wire are connected once to answer the call. There is a mobile phone 5 having a breaking function, and as shown in FIG. 1, the main body 2 has an internal microphone 3 for a mobile phone and an external switch for connecting the changeover switch 4 and the external stereo earphone 1. A main body 20 having a terminal and a terminal for connecting an earphone signal and a microphone signal of a mobile phone 5 and a terminal for connecting a stereo earphone signal output from the player 6 can be seen in FIG. As shown in the main body 20, which has a radio wave detection circuit 21 and a ring generator 22 that can know that a telephone call is received, the earphone and the microphone signal of the mobile phone 8 are connected from the outside. The signal output from the mobile phone 5 is divided into a microphone signal and an earphone output signal so that the microphone signal is connected to the microphone 25 and the switch 26, and the earphone signal is the contact point A of the switching switch 24 having two contacts. The earphone output from the player 6 which is connected to and is introduced through another path is divided into a control side and a right signal, respectively, and is connected to the contact B of the switching switch 24. Since the switching switch 24 is normally at the position of the contact B, the earphone 27 is connected to the output line of the player 6.

On the other hand, in the mobile phone, the microphone input line connects the microphone signal line and the ground line so that the incoming call can be received and the call can be disconnected when the connection is made again.

When the mobile phone 5 receives a signal for calling itself, it outputs a response signal. The radio wave detection circuit 21 detects the incoming call by detecting the strength of the signal output from the mobile phone as described above, and simultaneously generates a signal by driving the ring generator 22 circuit, where the ring tone is reproduced through the condenser 23. Since it is connected to the output side of the ringtone is transmitted to the earphone 27, the user will recognize that the phone call. The switching switch 24 and the microphone switch 26 are structured to interlock, and the microphone switch 26 is a push switch, and when pressed and released, the switch is returned to its original state so that a call can be received. When a ring tone is heard in the earphone 27, the switch is connected to the contact point A by pressing the switch 24, and at the same time, the microphone switch 26, which is interlocked, is contacted once to allow a call. When the call is over, the microphone switch 26 is contacted once again by pressing the switch 24 again, and the switch 24 is moved to the contact point B to allow music listening.

The radio wave detection circuit 21 detects a signal when the mobile phone 2 sends a response signal when a call is received. The antenna 28 of the main body 20 is far from the antenna of the mobile phone 2, so the sensitivity is low. . In order to compensate for these disadvantages, the antenna 28 is extended to increase the sensing capability, and a ring 29 is provided at the end thereof, and the ring 29 is easily detachable from the antenna of the mobile phone 2.

The player 6 and the mobile phone 5 are independent portable products and are not related to each other. In general, the player 6 is normally operated and the mobile phone is used when making or receiving a call. At this time, since the player 6 is a stereo output, two earphones are required on the left and right, and the mobile phone has a structure requiring one earphone and a microphone, and thus cannot be used in combination with each other. In the present invention, in order to eliminate such inconvenience, the player (3) is equipped with a mobile phone microphone (3) and a switch (4) for switching the output, so that the earphone is held in the ear according to the operation of the switch (4). (6) It is easy to connect to the side or the mobile phone (5) to simplify the music enjoyment and use of the mobile phone.

Claims (2)

The microphone 25 has a mobile phone 5 having a function of answering a call by connecting a signal line and a ground, and interlocking with a radio wave detection circuit 21, a ring tone generator 22, a microphone 25, and a microphone switch 26. In the main body 20 having the changeover switch 24, which is normally used, the changeover switch 24 is positioned at the contact point B, so that the earphone 27 is connected to the output of the player 6 so that music can be listened to and a telephone call is made. When the radio wave detection circuit 21 detects a signal and drives the ring tone generator 22 to give a ringtone to the earphone 27 while listening to music, indicating that a call is received, and the user presses a switching switch 24 so that the contact point is at B. After moving to A, the path of the earphone is connected to the output line of the mobile phone, and at the same time, the microphone switch 26 is connected once and then restored. Press 24) As the contact point changes from A to B and the microphone switch 26 is connected and restored once, the telephone is disconnected and the path of the earphone 27 is connected to the output of the player 6 so that music can be enjoyed. Hands free device, characterized in that. In claim 1, in order to increase the sensitivity of the radio wave sensing circuit 21, the line of the antenna 28 extends from the main body 2 and a ring 29 is attached to the end to easily attach the ring to the antenna of the mobile phone 5. Hands-free device characterized in that the removable.
