In a point of view of the first body BD1, when the first body BD1 is coupled with the second body BD2, the first body BD1 may be regarded as being in a first coupling mode. When the first body BD1 is coupled with the first audio signal processing body SBD1, the first body BD1 may be regarded as being in a second coupling mode.
When the first body BD1 is in the first coupling mode, the mobile terminal 100 according to the embodiment of the invention may include a short range communication module 114 (refer to
The first speaker SPK1 included in the audio signal processing device 500 may have a higher performance than the basic speaker SPKB included in the second body BD2. In this instance, the user may receive an improved sound. When the first body BD1 is in the first coupling mode in accordance with the embodiment of the invention, the embodiment of the invention may be similar to a speaker system of a related art Bluetooth communication manner. The mobile terminal audio signal processing system 10 according to the embodiment of the invention may be characterized in the point of that the first body BD1 can be in the second coupling mode as well as the first coupling mode.
When the first body BD1 is in the first coupling mode, the audio signal processing device 500 according to the embodiment of the invention may include a first circuit board and a second circuit board.

Further, the battery 191 may be connected to the second body BD2 and fixed to the second body BD2. The battery 191 may be coupled with or separated from the second body BD2.
The coupling and the separation between the first body BD1 and the second body BD2 may be related to change of the battery of the mobile terminal 100. A cover of the mobile terminal 100 may be formed as one body along with the first body BD1. In particular, when a back cover is formed of metal, the cover of the mobile terminal 100 may not be separated from the first body BD1. In this instance, in a related art, it was difficult to change the battery of the mobile terminal 100. However, in the mobile terminal 100 according to the embodiment of the invention, the battery 191 may be connected to the second body BD2. Therefore, in the mobile terminal 100 according to the embodiment of the invention, the battery can be changed.
As shown in
As shown in
As the battery 191 is coupled with the first audio signal processing body SBD1, the first audio signal processing body SBD1 may be coupled with the first body BD1 and may perform a function of the second body BD2. Namely, as the first audio signal processing body SBD1 is coupled with the first body BD1, the battery 191 may provide the electric power.
As shown in
Namely, the mobile terminal 100 according to the embodiment of the invention may include the first audio signal processing body SBD1 and the first body BD1. Because the mobile terminal 100 includes the main earphone jack EPJ2 and the sub-earphone jack EPJ1, the mobile terminal 100 may process a plurality of audio signals. More specifically, the controller 180 of the mobile terminal 100 may output at least one of the plurality of audio signals to the main earphone jack EPJ2 and may output at least another of the plurality of audio signals to the sub-earphone jack EPJ1.
The main earphone jack EPJ2 and the sub-earphone jack EPJ1 may individually receive the audio signal.

Namely, the mobile terminal 100 may supply the first and second audio signals to the first and second speakers SPK1 and SPK2 positioned on both sides of the display 151 and may radiate a sound to the outside.
The sound radiated by the mobile terminal 100 may have gone through a process that the controller provides an information about the sound for the first and the second speakers SPK1 and SPK2, and that the first and the second speakers SPK1 and SPK2 convert the information of the sound into the sound. The controller 180 may separate an information (for example, an audio signal) about a sound which will be radiated, into first and second audio signals. The first and second audio signals, may have different frequency ranges from each other and, may overlap each other. The first and second audio signals may be combined to form the audio signal.
More specifically,
The mobile terminal 100 may include the first body BD1 and the second body BD2 in the first coupling mode. Further, the mobile terminal 100 may include the first body BD1 and the first audio signal processing body SBD1 in the second coupling mode. Thus, it is preferable, but not required, that a type of the coupling mode is first checked because the components of the mobile terminal 100 may vary depending on the coupling mode.
Namely, the controller 180 of the mobile terminal audio signal processing system 10 according to the embodiment of the invention may determine whether or not the first body BD1 is in the first coupling mode in step S100.
When the first body BD1 is in the first coupling mode, the mobile terminal 100 may include the first body BD1 and the second body BD2.

In the first coupling mode, the mobile terminal 100 may play a sound, etc. using the audio signal processing device 500. To this end, the mobile terminal 100 may need to first recognize the audio signal processing device 500.
The mobile terminal 100 may recognize the audio signal processing device 500 through Bluetooth manner, for example. After the mobile terminal 100 recognizes the audio signal processing device 500, the mobile terminal 100 may transmit the audio signal to the audio signal processing device 500 through the wireless communication. The audio signal processing device 500 may receive the audio signal and convert the audio signal into a sound.
As shown in
When the main earphone jack EPJ2 is activated (or in an activated state), the main earphone jack EPJ2 may respond to the audio signal. Namely, when an earphone is inserted into the main earphone jack EPJ2, the controller 180 may output the audio signal to the main earphone jack EPJ2 if the main earphone jack EPJ2 is activated. Hence, the user may receive the sound through the earphone.
The operation step S400 of the mobile terminal 100 in the second coupling mode may include a step S420 of determining whether or not the sub-earphone jack EPJ1 is activated. When both the main earphone jack EPJ2 and the sub-earphone jack EPJ1 are activated, the mobile terminal 100 may obtain a touch input in step S430. Namely, the operation step S400 of the mobile terminal 100 in the second coupling mode may include the touch input receiving step S430. The obtained touch input may correspond to the selection of the main earphone jack EPJ2 and the sub-earphone jack EPJ1.
The operation step S400 of the mobile terminal 100 in the second coupling mode may include a step S440 of outputting the first audio signal to the main earphone jack EPJ2 and outputting the second audio signal to the sub-earphone jack EPJ1 through the controller 180 depending on the touch input.
When the sub-earphone jack EPJ1 is not activated and the main earphone jack EPJ2 is activated, the controller 180 may output the audio signal to the main earphone jack EPJ2 in step S450. Namely, the operation step S400 of the mobile terminal 100 in the second coupling mode may include a step S450 of outputting the audio signal to the main earphone jack EPJ2.
When the main earphone jack EPJ2 is not activated (or in an inactivated state), the activation or the inactivation of the sub-earphone jack EPJ1 may be a problem. Thus, the operation step S400 of the mobile terminal 100 in the second coupling mode may include a step S460 of determining whether or not the sub-earphone jack EPJ1 is activated.
When the main earphone jack EPJ2 is not activated and the sub-earphone jack EPJ1 is activated, the controller 180 may output the audio signal to the sub-earphone jack EPJ1. Namely, the operation step S400 of the mobile terminal 100 in the second coupling mode may include a step S470 of outputting the audio signal to the sub-earphone jack EPJ1.
As shown in
An example where both the main earphone jack EPJ2 and the sub-earphone jack EPJ1 have to be activated may be considered. Further, an example where one of the main earphone jack EPJ2 and the sub-earphone jack EPJ1 has to be activated may be considered. The controller 180 may be electrically connected to the main earphone jack EPJ2 and the sub-earphone jack EPJ1 and may be concerned in their activation. Namely, the controller 180 may determine the activation of the main earphone jack EPJ2 and the sub-earphone jack EPJ1.
The activation of the main earphone jack EPJ2 and the sub-earphone jack EPJ1 may be determined depending on a user input. The user input may be performed through a touch input. The display 151 may obtain the touch input. For example, as shown in
The user's touch input obtained through the display 151 may be transmitted to the controller 180. The controller 180 may cause each of the main earphone jack EPJ2 and the sub-earphone jack EPJ1 to be in one of the activated state and the inactivated state in response to the transmitted touch input of the user. In other words, the controller 180 may maintain or change a state of each of the main earphone jack EPJ2 and the sub-earphone jack EPJ1 in response to the user's touch input.
As shown in
The display 151 may receive the touch input from the user's finger UF and may transmit the touch input to the controller 180. The controller 180 may output the audio signal to the earphone jack corresponding to the transmitted touch input.
Selecting one of the main earphone jack EPJ2 and the sub-earphone jack EPJ1 may be performed on the assumption that both the main earphone jack EPJ2 and the sub-earphone jack EPJ1 are activated. The selection of the main earphone jack EPJ2 or the sub-earphone jack EPJ1 may depend on the user's selection. Further, the user may frequently change the earphone jack outputting the audio signal, if desired or necessary. For example, the user may select the main earphone jack EPJ2 and receive the sound through the main earphone jack EPJ2 while inserting the earphone into the sub-earphone jack EPJ1 to receive the sound.
As shown in
As shown in
As shown in
Namely, the first user U1 may receive the sound from the first sound file music#1, and the second user U2 may receive the sound from the second sound file music#2. As described above, the different users may receive different sounds from one device, i.e., the mobile terminal 100.

There may be first and second users U1 and U2 corresponding to the main earphone jack EPJ2 and the sub-earphone jack EPJ1, respectively. Only one of the first and second users U1 and U2 may control the mobile terminal 100.
It may be preferable, but not required, that an event signal of the mobile terminal 100 is transmitted to the user controlling the mobile terminal 100. Thus, it may be preferable, but not required, that an alarm and an event signal notifying a status of the mobile terminal 100 are output to one of the main earphone jack EPJ2 and the sub-earphone jack EPJ1. For example, an alarm event of the mobile terminal 100 may include a notification that the battery is low.
As shown in
When the event signal is output to the sub-earphone jack EPJ1, the first user U1 connecting the first earphone ERP1 to the sub-earphone jack EPJ1 may receive the event signal. In this instance, the first user U1 may substantially control the mobile terminal 100.
When the first and second users U1 and U2 receive a phone call on the mobile terminal 100 while listening to the music, it may be preferable, but not required, that the phone call is notified to the first user U1 substantially controlling the mobile terminal 100.
