The portable terminal according to the above feature may further include a control unit connected to the vibration motor, and the control unit applies the driving signal of the first driving frequency to the vibration motor when the operation mode is the vibration mode to apply the vibration motor. It is possible to function as a vibrator, and when the operation mode is a sound mode, a driving signal having a second driving frequency may be applied to the vibration motor so that the vibration motor functions as a speaker.

The portable terminal according to the feature may further include a user input unit connected to the control unit, and when the control unit determines that the call button is operated by a signal applied from the user input unit, the second driving frequency is driven. By applying a signal to the vibration motor, the vibration motor can function as a speaker.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In describing the present invention, when it is determined that adding a detailed description of a technology or configuration already known in the art may obscure the gist of the present invention, some of them will be omitted from the detailed description. In addition, the terms used in the present specification are terms used to properly express the embodiments of the present invention, which may vary according to persons or practices related to the field. Therefore, definitions of these terms should be made based on the contents throughout the present specification.

The terminology used herein is only to refer to a specific embodiment and is not intended to limit the invention. The singular forms used herein include plural forms unless the phrases clearly indicate the opposite. As used herein, the meaning of 'comprising' embodies certain properties, regions, integers, steps, actions, elements and / or components, and other specific properties, regions, integers, steps, actions, elements, components and / or groups. It does not exclude the existence or addition of.

Hereinafter, a portable terminal according to an embodiment of the present invention will be described with reference to the accompanying drawings.

First, referring to FIGS. 1 and 2, the portable terminal 1 according to an embodiment of the present invention will be described.

As shown in FIG. 1, the portable terminal 1 according to the present embodiment includes an upper case 10, a video display panel 20 positioned under the upper case 10, and a lower surface of the video display panel 20. It is provided with a vibration motor 30 located directly in contact with, and a lower case 40 positioned under the vibration motor 30.

As illustrated in FIG. 1, the portable terminal 1 is formed in a rectangular shape having a long axis and a short axis, and the vibration motor 30 may be located at one end in the long axis direction of the portable terminal 1.

At this time, in the space formed between the upper case 10 and the lower case 40, a circuit board and a battery in which electric and electronic devices such as camera modules, various sensors, and driving chips are mounted for operation of the mobile terminal 1 Additional components are built in.

The upper case 10 has a substantially rectangular planar shape, and is made of a transparent material such as glass or transparent plastic.

Therefore, the image through the operation of the image display panel 20 can be displayed to the outside.

The portable terminal 1 of this example is usually located at the upper end and does not have a receiving speaker located adjacent to the user's ear when making a phone call, but instead includes a vibration motor 30.

Accordingly, as illustrated in FIGS. 1 and 2, a separate hole (that is, a sound output hole) for outputting sound from the speaker is not located at an upper end of the upper case 10 corresponding to the receiving speaker.

Therefore, there are no components exposed to the upper surface of the upper case 10.

For this reason, the upper case 10 of this example is not provided with a hole formed in the thickness direction, so that both the upper and lower surfaces are blocked, and it is made of one plate shape having the same thickness regardless of the position.

The image display panel 20 is a panel for outputting an image toward the upper case 10 of the portable terminal 1, or a liquid crystal display panel using a liquid crystal or an organic light emitting diode (OLED). It may be made of an organic light emitting display panel.

The vibration motor 30 is directly attached to the lower surface of the image display panel 20, as shown in FIG. 2, and vibrates in a predetermined state under the control of the control unit 63, as shown in FIG. It functions as one of the vibrating unit generating the sound and the speaker outputting the sound.

The vibration motor 30 may operate in a vibration mode and a sound mode according to the purpose of operation. The mode in which the vibration motor 30 operates may be determined according to a range of driving frequencies applied to the vibration motor 30. The control unit 63 may generate a driving frequency suitable for each mode of the vibration motor 30.

In this example, when the vibration motor 30 is in the vibration mode and functions as a vibration unit, the magnitude of the frequency (eg, the first driving frequency) of the driving signal output from the control unit 63 to the vibration motor 30 is 100 to 250 Hz. Can be

In addition, when the vibration motor 30 is in the sound mode and functions as a speaker, the magnitude of the frequency (eg, the second driving frequency) of the driving signal output from the control unit 63 to the vibration motor 30 may be 50 to 10 kHz. have.

As described above, the vibration state of the vibration motor 30 changes according to the magnitude of the driving frequency applied from the control unit 63, so that the frequency (ie, vibration frequency) of the vibration generated in the vibration motor 30 is an inaudible frequency band or Since it has an audible frequency band, a corresponding sound or vibration in a corresponding state is generated according to the vibration frequency generated by the operation of the vibration motor 30.

In this example, the vibration motor 30 is located on the upper side of the portable terminal 1 so as not to adversely affect the expansion of the image display area.

Therefore, the vibration generated by the operation of the vibration motor 30 is transmitted to the upper case 10 through the image display panel 20 that is directly in contact with the image display panel 20 and the upper case 10, or It is output as sound to the outside.

The structure of the vibration motor 30 will be described in detail below.

The lower case 40 is for protecting the components located therein. The lower case 20 may be made of a material that is resistant to impact and moisture such as metal and has a light weight.

In this example, as the vibration motor 30 is directly located on the lower surface of the image display panel 20, the vibration transmission to the lower case 40 through the image display panel 20 is efficiently performed by the operation of the vibration motor 30. To do this, the side surfaces of the upper case 10 and the image display panel 20 are attached to the lower case 40 through a flexible member 41.

Next, the structure of the vibration motor 30 of this example will be described with reference to FIG. 3.

As shown in FIG. 3, the vibration motor 30 of this example includes a housing 31, a stator 32, a vibrator 33, and an elastic body 34.

The housing 31 is provided with a vibration motor 30 therein to protect the vibration motor 30 from the outside.

Therefore, the housing 31 has a space in which the vibration motor 30 is located, and the stator 32, the vibrator 33, and the elastic body 34 are located in the inner space of the housing 31.

The housing 31 may be formed of a cylindrical pillar or a polygonal pillar, and the shape of the inner space is determined according to the shape of the housing 31.

The housing 31 includes a bracket 311 and a case portion 312 connected to the bracket 310.

The bracket 311 forms a lower portion of the housing 31, and has a circular or multi-planar flat shape.

The case part 312 is located on the bracket 311 and serves as a cover of the vibration motor 30.

The case portion 312 constitutes a side portion and an upper portion of the housing 31, and a lower portion is formed in an open shape, and an inner space, which is an empty space, is opened through the lower portion.

Therefore, the stator 32, the vibrator 33, and the elastic body 34 are located in the inner space surrounded by the bracket 311 and the case portion 312.

The bracket 311 and the case portion 312 may be made of a magnetic material or a non-magnetic material.

The stator 32 and the vibrator 33 located in the inner space of the housing 31 generate electromagnetic force by interaction. Accordingly, the vibrator 33 generates a vibration by linear reciprocating motion by electromagnetic force generated by interaction with the stator 32.

The stator 32 and the vibrator 33 are relative to each other, and the stator 32 refers to a portion fixed to the vibrator 33 and the vibrator 33 refers to a portion vibrating with respect to the stator 32.

In this example, the stator 32 includes a circuit board 321, a circuit board 321, and a coil 322 positioned on the case portion 312.

In addition, the vibrator 33 includes a magnet 331 and a weight 332 connected to the magnet 331.

However, unlike this example, depending on the design of the vibration motor, on the contrary, the stator 32 may be provided with a magnet and the vibrator 33 may be provided with a coil.

The circuit board 321 of the stator 32 may be formed of a printed circuit board (PCB) on which a driving circuit for controlling the operation of the vibration motor 30 is mounted, for example, a flexible printed circuit It can be made of a flexible printed circuit board (FPCB).

The coil 322 is located on the circuit board 321, which is a lower portion of the housing 31, and is a coil provided with a yoke 3221 and an iron wire 3222 wound multiple times in the corresponding direction on the yoke 3221. .

Both ends of the coil 322 are electrically and physically connected to the corresponding terminals of the circuit board 321, so that an electrical signal, eg, alternating current, is applied to the coil 322 from the circuit board 321 through the corresponding terminals. Electromagnetic force (that is, vibration force) is generated by interaction with the magnet 331.

The direction of the alternating current applied to the coil 322 may be determined according to the magnetization form of the magnet 331 and the arrangement relationship between the coil 322 and the magnet 331.

The vibrator 33 has a magnet 331 and a weight 332, as already described.

The magnet 331 has a polygonal column shape, such as a cylindrical or square column, which has an empty space in which the coil 322 is inserted into the center portion.

Therefore, the coil 322 is inserted into the empty space located in the middle, and the magnet 331 surrounds the portion of the coil 322 inserted into the space in the surroundings.

The weight body 332 is an object having a predetermined size of weight, and since the resonant frequency of the vibrator 33 can be determined by the mass of the weight body 332, the mass of the weight body 332 is adjusted to adjust the vibrator 33. Can have the maximum amount of vibration.

The weight body 332 is preferably made of a material having a relatively high specific gravity, and may also be made of a non-magnetic material.

For example, the weight body 332 may be made of a material having a specific gravity greater than iron, such as tungsten.

As already described, since the weight 332 is coupled to the magnet 331 located adjacent, the weight 332 also vibrates when the magnet 331 is vibrated by electromagnetic force.

In this example, the weight body 332 has a predetermined thickness and has a polygonal hole such as a substantially circular shape or a square shape in the center portion, so that the magnet 331 in the form of a cylinder or a polygonal column is inserted into the hole located therein. Since it is mounted in contact with the inner side of the weight body 332, the magnet 331 and the weight body 332 are coupled to each other.

The weight body 332 has a circular or polygonal planar shape with a hole in the center portion.

The vibration motor 30 of this example is provided with one coil 322 and one magnet 331, but unlike this, the number of coils 322 and the magnet 331 may be plural. At this time, the number of coils and magnets located in the interior space of the weight 332 may be determined according to the performance or size of the vibration motor, the structure or size of the weight 332, and the like.

The elastic body 34 is for connecting the vibrator 33 to the housing 31, and may be formed of a plate spring having a shape such as a circular shape or a square shape having elastic force.

In this example, the elastic body 34 may be coupled to a portion of the housing 31 that is combined with the image display panel 20.

The elastic body 34 is an inner plate portion (eg, one end) 341 positioned inside the elastic body 34, and an outer plate portion formed on the outer edge portion of the elastic body 34 outside the inner plate portion 341 (eg, The other end) 342 may be provided, and a connection portion 343 connecting the inner plate portion 341 and the outer plate portion 342.

Referring to FIG. 3, the elastic body 34 is disposed between the upper inner surface of the housing 31, that is, more specifically, the upper inner surface portion of the case portion 312 and the upper surface of the weight body 332. Connect.

To this end, as an example, the outer plate portion 342 of the elastic body 34 is coupled with the edge portion of the upper inner surface of the case portion 312, and the inner plate portion 341 is combined with the upper surface of the weight body 332 do.

However, on the contrary, in another example shown in FIG. 4, the inner plate portion 341 of the elastic body 34 is engaged with the upper inner surface of the case portion 312, and the outer plate portion 342 is of the weight body 332. It is combined with the upper edge.

Except for the connection structure of the elastic body 34, the vibration motor shown in FIG. 4 is the same as the structure of the vibration motor shown in FIG.

At this time, the elastic body 34 and the corresponding parts 312 and 332 are joined using welding or the like, but may be joined through various other methods.

Due to the elastic body 34, the vibrator 33 is coupled to the upper portion of the housing 31 to perform a vibration operation in the vertical direction.

As described above, the vibration motor 30 operates under the control of the control unit 63 to generate vibration or output sound.

Next, a control operation for driving the vibration motor 30 will be described with reference to FIGS. 5 to 7.

5, the control unit for controlling the vibration motor 30 is connected to the user input unit 61, the communication unit 62, the user input unit 61 and the communication unit 62 and driven by the vibration motor 30 A control unit 63 for outputting a signal and a storage unit 64 connected to the control unit 63 are provided.

In this example, this control unit also constitutes part of the portable terminal 1 according to the present embodiment.

The user input unit 61 generates a command input for controlling the operation of the portable terminal 1 or a signal related to an input operation of data and outputs the signal to the control unit 63.

The user input unit 61 may be formed of a touch screen, and in this case, the image display panel 20 is a sensor for detecting a touch operation as well as a structure for displaying an image (hereinafter referred to as a 'touch sensor'). ] May have a mutually layered structure, and the image display panel 20 may constitute a part of the touch screen.

The communication unit 62 is for communication with an external device and includes one or more communication modules.

For example, the communication unit 62 may include a mobile communication module, an Internet module, and a short-range communication module.

At this time, the mobile communication module transmits and receives a signal (ie, a radio signal) wirelessly with at least one of a base station, an external terminal, and a server on the mobile communication network. The wireless signal may include various types of data according to transmission and reception of a voice call signal, a video call signal, or a short message or multimedia message.

The Internet module refers to a module for wireless or wired Internet access.

At this time, as the Internet technology, a wireless LAN (WLAN) (WiFi), a wireless broadband (Wibro), a world interoperability for microwave access (Wimax), or a high speed downlink packet access (HSDPA) may be used.

The short-range communication module is a module for short-range communication, and the short-range communication technology includes Bluetooth, Radio Frequency Identification (RFID), Infrared Data Association (IrDA), Ultra Wideband (UWB) or ZigBee. Can be used.

The control unit 63 may be mounted on a circuit board 321 located in the vibration motor 30 or a circuit board located in the interior space of the portable terminal 1,

According to the operation of the user input unit 61, the operation mode of the mobile terminal 1, more specifically, the vibration motor 30 is set, the operation of the vibration motor 30 is controlled according to the set operation mode, and the communication unit 62 ) When a call signal such as a voice call signal or a video call signal or a message such as a short message or a multimedia message is received, the vibration motor 30 is driven by a vibration unit or a speaker according to a predetermined operation mode.

The storage unit 64 is a storage medium that stores data necessary for the operation of the control unit 63 or data generated during the operation, and may be a memory.

The operation of the control unit having such a structure is shown in FIGS. 6 and 7.

First, referring to FIG. 6, an operation of selecting an operation mode of the portable terminal 1, that is, the vibration motor 30 according to the user's operation using the user input unit 61 will be described.

First, when the operation of the portable terminal 1 is started, the operation of the control unit 63 is also started (S10), the signal applied from the user input unit 61 (eg, a user input signal) is read (S11), and the operation is performed. It is determined whether an operation mode selection signal for changing a mode has occurred (S12).

In this example, the operation mode is for informing the user of the portable terminal 1 when a call is received or a message is received through the communication unit 62, and includes a vibration mode, a sound mode, and a silent mode. have. Therefore, the user selects one of these modes.

When the operation mode selection signal is generated by changing the operation mode (vibration mode, sound mode, and silent mode) of the portable terminal 1 by a user's operation using the user input unit 61, the control unit 63 is applied. The type of the operation mode selected by the user is determined using the state of the mode selection signal (S13).

Then, according to the type of the determined operation mode, the operation mode of the current vibration motor 30 is stored in the storage unit 64 as the determined operation mode (that is, one of the vibration mode, the sound mode, and the silent mode) (S14). ~ S18).

In this way, the user selects the operation mode of the portable terminal 1 in a desired type through the user input unit 61.

Next, referring to FIG. 7, the operation of the control unit 63 that controls the operation of the vibration motor 30 will be described after the operation mode of the user terminal 1 is determined.

First, the control unit 63 determines whether a call signal is received through the communication unit 62, and when a call signal for a phone call such as a voice call or a video call is received, the current operation mode stored in the storage unit 64 The setting state of is determined (S21, S22).

Accordingly, the control unit 63 controls the operation of the vibration motor 30 according to the type of operation mode currently set.

That is, when the currently set operation mode is the vibration mode, the control unit 63 applies the driving signal of the first driving frequency to the vibration motor 30 so that the vibration motor 30 operates as the vibration unit.

Accordingly, the vibration motor 30 operates according to the applied driving signal to generate vibrations having a vibration frequency of a corresponding size and notifies the user that a call has been received (S23, S24).

However, when the type of the determined operation mode is a sound mode (S25), the control unit 63 applies a driving signal having a second driving frequency different from the first driving frequency to the vibration motor 30 so that the vibration motor 30 is To operate as a speaker (S25, S26).

Accordingly, the vibration motor 30 operates according to the applied driving signal to generate a vibration frequency in the audible frequency band and outputs the corresponding telephone sound (S23, S24).

However, when the type of the operation mode is not the vibration mode or the sound mode, the control unit 63 determines the current operation mode as the silent mode, and does not output a separate driving signal to the vibration motor 30.

As described above, after the operation of the vibration motor 30 is controlled according to the type of each determined operation mode, the control unit 63 reads the signal applied from the user input unit 61 to make a phone call by the user's operation. It is determined whether the call button is driven (S27, S28).

When it is determined that the call button is driven, the control unit 63 outputs a driving signal of the second driving frequency to the vibration motor 30 to convert the operating state of the vibration motor 30 into a speaker (S29).

For this reason, a voice signal transmitted from the phone of the other party who normally makes a phone call is output through the vibration motor 30 to make a normal phone call.

Then, the control unit 63 determines whether the call end button for the call type is in operation through a signal applied from the user input unit 61 (S210).

Therefore, when it is determined that the call termination button is operated (S210), the control unit 63 stops the output of the driving signal of the second driving frequency applied to the vibration motor 30 so that the phone call can be terminated ( S211).

However, in step S28, if it is determined that the call button is not operated (S28), the control unit 63 determines whether the call end button for the call type is activated through a signal applied from the user input unit 61. It is judged (S212).

Accordingly, when it is determined that the call end button is operated (S212), the control unit 63 stops output of the driving signal of the first or second driving frequency applied to the vibration motor 30, and uses vibration or sound. The call reception notification operation ends (S213).

In addition, even when a message is transmitted through the communication unit 62, as shown in FIG. 7, an operation mode (vibration mode, sound mode) determined by determining an operation mode using data stored in the storage unit 64 Alternatively, a driving signal having a first or second driving frequency is applied to the vibrating motor 30 according to the silent mode), or a driving signal is not output.

At this time, when the driving signal of the first or second driving frequency is applied to the vibration motor 30, the control unit 63 applies the driving signal only for a predetermined time when a message is received.

Accordingly, the user recognizes the message reception state by vibration or sound generated by the operation of the vibration motor 30 operating for a set time.

Since the portable terminal 1 of this example does not require a separate speaker for a phone call and an operation mode, there is no need to secure space for mounting the speaker, so the design margin increases, and the manufacturing cost of the portable terminal 1 also decreases. do.

In addition, since the sound output hole formed corresponding to the speaker is unnecessary due to the removal of the speaker, the video display area of the video display panel 20 can be further increased.

Moreover, when the vibration motor 30 of this example functions as a speaker, a separate vibration plate is unnecessary, so the structure of the vibration motor 30 is simpler and the manufacturing cost is further reduced.

The embodiments of the portable terminal of the present invention have been described above. The present invention is not limited to the above-described embodiments and the accompanying drawings, and various modifications and variations will be possible from the viewpoint of those having ordinary knowledge in the field to which the present invention pertains.
