The electronic device 200 of the present invention includes a band 210, a housing 220, an acoustic cable 245, a receiver 240, a wireless communication unit 255, and a controller 250.

Band 210 is a member bent in a U-shape can be hooked from the back to the neck. It can be made of a material that can be easily bent for ease of use. If the band 210 is all made of a rigid material, it is inconvenient when worn on the neck and there is a risk of breakage when carrying it in a bag, etc., and a flexible material can be used. Can be.

A space may be formed inside the band 210 to provide a wire-type power supply unit 257, a wireless communication unit 225, and a flexible printed circuit board for transmitting signals.

The housing 220 is located at both ends of the band 210, and the control unit 250, the wireless communication unit 255, the microphone 248, the sensing unit 260, the operation unit in the inner space formed by combining the upper housing and the lower housing 270, a power supply unit 257, a notification unit 247, and the like are mounted.

The electronic device 200 may use a vibration method to inform the user of the event. The vibrator may be provided inside the housing to operate the vibrator 247 as well as an indicator to inform the user that a new event has occurred.

In the housing 220, a charging terminal for charging may be located, and a cap 228 may be provided to prevent the surface from being exposed.

On the surface of the housing 220, a first button 271 for playing / calling and power on / off, a second button 272 and a third button for adjusting a sound or changing the order of files to be played 272 and 273 may be provided.

The

buttons

271, 272, and 273 may use a rotating jog button, a slide button for inputting a push signal, or a dome switch button having a dome switch. In this case, the

buttons

271, 272 may be used in the housing 220. , An opening for 273 may be formed.

In addition, the

buttons

271, 272, and 273 may input signals by touching a user using a touch sensor. As shown in FIG. 2, the first button 271 may be located at one side, the second button 272 and the third button 273 at the other side, or both may be disposed at one side.

The type of functions that can be performed with the three buttons is limited, and since the intuition is inferior to that of the input method using the touch key output on the display panel, the user needs a button operation method that is easier to learn. .

Short presses of the first button 271 to the third button 273 may generate a short input signal, long press to generate a long input signal, and press a plurality of times to generate a double input signal. Alternatively, a plurality of buttons can be simultaneously pressed to input new signals through a combination of input signals. The electronic device of the present invention can generate various input signals using one button to control the electronic device in various ways.

Hereinafter, a method of inputting various control commands through a combination of short input signals, long input signals, double input signals, and input signals detected by the controller 180 through the

buttons

271, 272, and 273 will be described.

The electronic device 200 of the present invention may control detailed commands for several main operations using three buttons. As shown in the present embodiment, the external terminal and the wireless communication unit 255 perform functions such as connection (synchronization), telephone call, and music playback, and generate a control command with the three buttons to control the function as desired by the user. can do.

The first button 271 is mainly responsible for power, call, and playback functions, and the second button 272 and third button 273 are responsible for functions such as changing volume and playback order. The second button 272 and the third button 273 may match a command related to the directional function, and the first button 271 may match a command such as determination, termination, and progress.

First, when the electronic device 200 is used for the first time, it must be connected to an external terminal. To turn on the power, press the first button 271 or more. The reference time is suitably about 1 to 2 seconds. If too short, even if pressed unintentionally there is a problem that the power is turned on, if too long there is a problem inconvenient use. The first button 271 is also available when the power is turned off, and in this case, the input button may be generated by pressing the button slightly longer than when the power is turned on.

This is to distinguish between the long input signal when the power is turned off for various inputs with a limited number of buttons since the power is turned on, and the long input signal for inputting other commands. For example, a general long input signal may be set to be 1 second or longer, and to turn on the power when an input signal is detected for 2 seconds or more, and to turn off the power when an input signal is detected for 3 seconds or more.

When the power is turned on, the wireless communication unit 255 is also activated and searches for a connectable external terminal. In case of connecting with a neighboring external terminal, Bluetooth can be generally used.

In this case, the electronic device 200 is registered to an external terminal at the first connection so that no terminal is arbitrarily connected, or a log of the electronic device 200 connected to the electronic device 200 is stored in the memory of the electronic device 200. Can record

Since the initial registration is difficult when the electronic device 200 does not have a display unit, the electronic device 200 is selected from a list of one or more electronic devices 200 provided through an external terminal, and a unique authentication number of the electronic device 200 is input. The electronic device 200 and the external terminal can be connected (synchronized). Thereafter, the connected external terminal may be automatically reconnected when the electronic device 200 is turned on.

If the automatic connection is not desired, the electronic device 200 needs to be turned on in another way for manual connection, so that the first button (while pressing the second button 272 or the third button 273) is pressed. If the long input signal is input by pressing and holding 271), the terminal does not automatically connect with the external terminal and waits for another external terminal to request connection with the electronic device 200. The electronic device 200 may be connected to a new external device while the electronic device 200 is turned on by a method different from the general power on.

In general, when another external terminal attempts to connect with the electronic device 200 while being connected to one external terminal, the connection of the external terminal previously connected is disconnected, and the other external terminal is connected with the electronic device 200.

Alternatively, it can be connected to two external terminals at the same time. First, the first external terminal is connected by a manual connection method so as not to be disconnected from the connected external terminal. When the external terminal connected by the automatic connection method is disconnected from the first connected external terminal when another external terminal is connected, the external terminal connected by the manual connection method additionally attempts to connect to the electronic device 200 from another external terminal. The connection is maintained without breaking, allowing multiple connections.

When connected to an external terminal, the electronic device 200 may perform some of the functions of the external terminal. The electronic device 200 according to the present embodiment may include a sound output unit for outputting a sound. The electronic device 200 may perform a telephone call function or use a reproduction function of sound data using a mobile communication device of a connected external terminal.

First, let's take a look at the functions for telephone call and operation method using buttons. When a call is received by the external terminal, the external terminal notifies the electronic device 200 that the call is received. When the user is listening to music, the output sound may be stopped and a call reception sound may be provided, or a notification may be provided using the vibrator 247.

When a call is received, the user may briefly press the first button 271 to transmit a short input signal to the controller 250 to receive a call. In a situation in which it is difficult to answer a call, the user may move the first button 271 to a reference time or more. The long press may be transmitted to the control unit 250 to reject the long input signal. Or, if a notification sounds through a vibration or speaker, you can stop the sound output from the vibration or the speaker to move to receive a call. In order to turn off the notification while the call signal is maintained, the third button 273 is briefly pressed to provide a short input signal of the third button 273 to the controller 250 or the second button 272 and the third button 273. When simultaneously pressing the single input signal to the controller 250, the controller 250 may stop the notification by controlling the vibrator or the speaker.

The call may be initiated in response to the call signal and the volume may be adjusted during the call by briefly pressing the second button 272 and the third button 273. Alternatively, when the transmission sound is to be cut off for a while, the microphone function of the electronic device 200 may be temporarily turned off by pressing and holding the second button 272 and the third button 273 simultaneously. When the second button 272 and the third button 273 are simultaneously pressed again, the microphone function of the electronic device 200 is reactivated to make a call.

A short press of the first button 271 may terminate the telephone call, and when another call signal is received during the call, the first button 271 may be pressed to answer the newly received call signal.

Alternatively, when a direct call is desired using a mobile terminal during a call (for example, when the sensitivity of the electronic device 200 is decreased or a speakerphone function of an external terminal is used), communication can be switched to an external terminal. When the long input signal of the second button 272 or the third button 273 is detected, the controller 250 may perform communication switching.

When the user wants to make a call in addition to the call by the received call signal, the electronic device 200 may use a voice dial function so that it is difficult to directly input a phone number. In order to activate the voice dial function, the first button 271 may be briefly pressed to enter the voice dial mode. In this case, the user may call the contact number by searching for the contact's name recorded in the address book of the external terminal. Alternatively, when the user speaks a phone number, the user may recognize the phone number and call the number.

Alternatively, when a long input signal of the first button 271 is detected, a redial function of redialing the last called party may be performed. In order to make a call, the user may press the first button 271 briefly twice to use a voice dial method, or press and hold the first button 271 to make a call using a redial method.

Next, the sound data reproduction function will be described. One of the sound data stored in the external terminal can be reproduced. When the double input signal of the first button 271 is detected, the controller 250 may reproduce the sound data. In this case, the reproduced sound data may reproduce the most recently reproduced sound data or the sound data located first in the sound data list. When the double input signal or the long input signal of the first button 271 is detected while the sound data is being reproduced, the controller 250 may stop the reproduction.

In order to adjust the sound output according to the sound data, the input signal of the second button 272 and the third button 273 may be used. In order to change the playback position of the sound data being reproduced, it is possible to fast forward using the long input signal of the second button 272 and to fast backward using the long input signal of the third button 273.

The multi-input signal of the second button 272 and the third button 273 may be used to select the sound data to be reproduced in the sound data list. The double input signal means that the single input signal is input two or more times in succession. When the second input button 272 is pressed twice to generate the double input signal, the previous song of the currently playing song in the list of sound data is played. When the third button 273 is pressed twice to generate a double input signal, the next song of the song currently being played in the list of sound data may be played.

Conversely, a double input signal may be used for the fast-forward function, and a long input signal may be used for the playback song skip function. That is, the two functions can be changed and set.

In addition, when the first button 271 and the second button 272 are simultaneously pressed while the audio data is reproduced, the long input signal may be applied to enter the sound setting mode. In the sound setting mode, the sound mode may be adjusted by the second button 272 and the third button 273.

In addition, by pressing and holding the second button 272 to activate or turn off the notification function using the vibration or the speaker, it can be set by pressing and holding the third button 273 to know the state of charge of the battery. Table 1 is a table summarizing the above contents. MFB means a first button 271, a volume up button means a second button 272, and a volume down button means a third button 273.

The function is not limited thereto, and the electronic device 200 of the present invention and the connected external terminal may be controlled using a combination of input signals of the first button 271 to the third button 273 to set another function. Can be.

As the display unit is located at the front side and the function of the display unit is expanded, the front space can be devoted to the display unit as much as possible, and other parts can be arranged using the rear side or the side surface. For example, the camera 121b, the sound output unit 152b, the user input unit, and the like may be located at the rear side.

The camera 121b processes an image frame of a still image or a moving image obtained by the image sensor in the photographing mode or the video call mode. The processed image frame may be displayed on the display unit 151 and stored in the memory 170.

The sound output unit 152b may be implemented in the form of a loud speaker for outputting various alarm sounds or multimedia reproduction sounds, and has a receiver-type sound output unit for transmitting a call sound to a user's ear on the front surface. can do. A separate sound device may be connected to an ear jack, or may be connected by using a short range wireless communication method to output sound through the sound device.

And three user inputs exposed on the housing surface. Unlike the above-described embodiment, the present embodiment may input a user command using the display unit on the front surface, but if the user controls the electronic device 100 without directly viewing or when the touch sensor malfunctions, the electronic device may be touched.
