Abstract
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for controlling an earphone, a headphone, and a speaker by tapping an earphone, a headphone speaker, Using this device, control signals such as volume control, music selection, and application execution can be input to the audio device without changing the hardware of the audio device. That is, by using the connecting device of the present invention between the audio input / output terminal of the audio device and the earphone plug, the earphone signal can be input to the microphone of the audio device.
Description
The present invention relates to an apparatus for controlling an earphone, a headphone, and a speaker by connecting them to an audio device by tapping an earphone, a headphone speaker or the like. Using this device, control signals such as volume control, music selection, and application execution can be input to the audio device without changing the hardware of the existing audio device.
With the development of digital technology, mobile devices having the function of reproducing music and multimedia are increasingly developed and becoming more common. MP3 players, PMPs, electronic dictionaries, and especially recently, the popularity of audio devices has made it easier to enjoy music. Use earphones or headphones to listen to music or voice signals on mobile devices. When listening to music and voice on a mobile device, there are frequent changes in environment such as noise depending on the surrounding situation, so that it is necessary to adjust the volume. In addition, users often operate the device through a touch display such as a control button of a mobile device or an audio device for selection.
Mobile devices are often used mainly in pockets or bags due to their characteristics, and users have to take out and operate the device whenever it is necessary to operate it. Among the existing technologies to solve this problem, a method of putting a variable resistor between the earphone terminal and the earphone driver unit has been devised to facilitate volume control. The method of adding a variable resistor can be adjusted to a smaller volume than the volume sent from the device by adjusting the value of the variable resistor, but it can not obtain a volume higher than the volume sent from the device. In addition, because of the variable resistance, noise or breakdown often occurs due to mechanical wear, dust, etc. during prolonged use.
Another conventional technique is to put a control button in the middle of the earphone line and to control the volume control, selection and so on by sensing the button press in the device. However, in order to use the control button on the earphone line, one or more additional terminals are required for the device. A commonly used earphone without a control button has a plug with three terminals and a driver unit that converts electric signals into sound. The three-pole terminal is the terminal required to receive the stereo electric signal, and serves as left, right, and ground respectively. In order to put the control button on the stereo earphone and to transmit the control button signal to the device, we had to add a pole to make it at least 4 poles. However, this method has inconvenience that a control signal can not be input by using a general earphone without a control button. This method has several drawbacks and can be summarized in four ways. The first is the disadvantage of adding a control to the earphone line which should be light. Secondly, the cost of earphones and headphones will increase due to the control unit on the earphone. Third, there is a risk that the controller will fail when used for a long time. Pressing the button for the fourth time is more uncomfortable than expected. For example, finding the desired button and double-clicking it is more annoying than it sounds.
Previously, in order to make calls through earphones, it was necessary to use earphones with a microphone. If the earphone does not have a microphone with good sound quality, it is inconvenient to purchase an earphone with a microphone.
In order to solve the inconvenience described above, a technique has recently been proposed in which a control signal is input by tapping an earphone. This technique detects an induced voltage generated by tapping an earphone in an audio device, detects that the user has tapped the earphone, and inputs a control command using the detection. In order to apply this technique, it is necessary to connect the earphone Play line to the microphone of the audio device, and to change the hardware so that the audio device can detect the induced voltage. There is a way to redesign the audio equipment to connect the line inside the audio equipment, but it is difficult to change the hardware of the already released audio equipment.
In order to reduce or solve the above-described problems, the present invention proposes a method of connecting an earphone signal to a microphone of an audio device without connecting the audio device to the audio device. That is, by using the connecting device of the present invention between the audio input / output terminal of the audio device and the earphone plug, the earphone signal can be input to the microphone of the audio device.
In the absence of the connecting device of the present invention, there is no way to transmit the voltage generated by the earphone tapping to the microphone of the audio device. The present invention provides a convenient function in that a connecting device according to the present invention can use tap control when a program for tapping detection is put in a conventional audio device. In addition, since it is not necessary to change the hardware of existing audio products, it is very likely to be used in the industry.
FIG. 1 is a diagram illustrating an example in which a microphone terminal of an audio device is connected to a left play line of an earphone, and a knock signal of the earphone is connected to a microphone terminal of the audio device to measure an induced voltage generated by tapping.
FIG. 2 is an example of connection between a left play line of a connection terminal of an audio device and a condenser without directly connecting the microphone.
3 is an exemplary diagram of the present invention connecting an audio device and an earphone.
Hereinafter, an embodiment will be described in detail with reference to the accompanying drawings. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced without these specific details. Also, well-known methods, components, and circuits have not been described in detail so as not to obscure aspects of the embodiments.
The present invention relates to an apparatus for connecting an audio device and an earphone, and at least one terminal of an audio device output is connected to a microphone terminal of the audio device, so that an induced voltage signal induced by tapping of the earphone main body can be measured at a microphone terminal Device.
Some audio devices have a device that accepts user input while changing the resistance of the play line and microphone line. In order to use the present invention in such an audio device without collision, it is possible to prevent collision by connecting at least one of the outputs of the audio device and a microphone terminal of the audio device through a capacitor. The capacitor makes the resistance of the connection line close to infinity and allows only AC to pass. By doing this, the microphone and the play line can have a non-short-circuited effect.
In the present invention, an earphone refers to an audio transducer that converts electric signals into sound vibrations. It should be understood that the present invention can also be applied to headphones and speakers. Also, it should be understood that the left play line can be applied to the right play line as well.
