FIG. 1 is a block diagram of a portable acoustic device 300 according to an embodiment of the present invention. FIG. 2 is a perspective view of the portable acoustic device 300 according to an embodiment of the present invention, 1 is an exploded perspective view of a portable acoustic device 300 according to an embodiment of the present invention. For convenience of description, FIGS. 1 to 3 are also referred to.

 The portable acoustic device 300 of the present invention includes a control unit 380, a wireless communication unit 385, an acoustic output unit 340, a sensing unit 375, a microphone 360, a user input unit 370, and a power supply unit 390, .

The sound output unit 340 is a device for outputting sound in accordance with a sound signal. As a representative example, there is an ear bud 340 that transmits sound by being inserted into a user's ear.

The wireless communication unit 385 can receive the sound signal from the external terminal. The received acoustic signal may be transmitted to the acoustic output module of the ear bud 340 and sounded through the ear bud 340.

The microphone 360 processes the external acoustic signal into electrical voice data. The processed voice data is transmitted to an external terminal or an external server through the wireless communication unit 385. The microphone 360 may be implemented with various noise reduction algorithms for eliminating noise generated in receiving an external sound signal.

The sensing unit 375 recognizes the state of the portable acoustic device 300 itself and its surroundings. The sensing unit 375 includes an illuminance sensor for sensing the brightness of the surroundings, a touch sensor for sensing the touch input, A gyro sensor for detecting an ear bud 340, an ear bud switch for detecting whether or not an ear bud 340 is positioned in the ear bud holder 325, and the like. In addition, it may include a contact sensor that detects whether it is folded or unfolded when it is composed of a foldable body.

The user input unit 370 is an input unit for the user to control the portable acoustic device 300 and includes a call button 372, a button 373 for controlling the volume, a power button 371, and an acoustic cable 345, And a storage button 375 for storing the inside of the body 320.

The number of the user input units 370 may include only a call button 372 and a pair of volume control buttons 373, and may further include a play / stop button and a music order change button. Since the size of the portable audio device 300 is limited and the user input unit 370 often inputs without looking directly at the user, if the number of buttons is large, it is difficult to distinguish the functions of the respective buttons. And a control command that can be input by combining a plurality of buttons.

Since the portable audio device 300 maintains the wear state of the user, the risk of loss of the portable audio device 300 is small. However, the normal user terminal may be lost, and the user input unit 370 may perform an alarm function. For example, when two user input units 370 are simultaneously pressed for a predetermined time, an alarm of a terminal connected through Bluetooth can be called to find a lost terminal.

In addition, the voice recording function of the external terminal connected via Bluetooth can be activated to store the voice collected through the microphone 360 of the portable acoustic device 300.

In the related art, only the functions related to the call or the functions related to the playback of the sound media can be controlled by the portable sound device. However, the portable sound device of the present invention has an expanded control range.

The main body of the portable acoustic device 300 of the present invention is composed of the supporting body 310 and the full-length body 320 and forms a C-shaped curve as shown in FIG. The entire body including the supporting body 310 and the full-length body 320 may have a C-shaped curved shape, and only the supporting body 310 may have a C-shaped curved shape. Since the support body 310 corresponds to an area of the user's neck, the support body 310 can have an ergonomic structure stably mounted on the user's neck by having a curved shape.

At both ends of the support body 310 mounted behind the user's neck, there is provided a full-length body 320 which forms a full-length portion. However, if necessary, the supporting body 310 may also be provided with an electric part to mount electronic parts, so that it is not necessary to distinguish between the two functions.

The support body 310 is resilient and deformed within a predetermined range upon application of force, and returns to its original shape when the force is removed. When the distance between the full length bodies 320 at both ends is not sufficient to pass through the neck, the elasticity of the support body 310 can be used to open the full length body 320 and mount or unmount the entire length body 320 .

The shape and length of the support body 310 are determined to minimize the foreign body sensation when the user supports the neck 310. For example, the support body 310 may be provided in a curved cylindrical shape, or may be provided in a twisted tape shape having a thickness and a thickness. In the case of a twisted tape-shaped support body 310, the inner surface of the support body 310 is on the back of the neck and the outer surface is on the back. A portion of the support body 310 and the entire body 320 may be twisted so that the entire body 320 faces the front or upper face of the user and the inner face faces the back or collarbone portion of the user.

The full-length body 320 is coupled to both ends of the support body 310 and is positioned at both ends of the C-shaped curve of the portable acoustic device 300. Various components such as a main board 381, a wireless communication unit 385, and a battery 391 rotation module 350 are inserted into the inside and the outside.

The C-shaped portable acoustic device 300 can be worn on the user's neck and carried. At this time, the sensing unit 375 provided in the portable acoustic device 300 can detect whether or not the user wears the apparatus. For example, the sensing unit 375 may be implemented in the form of a displacement sensor provided in the support body 310 to sense a change in the curvature of the support body 310. The displacement sensor can detect that the user widening the full length body 320 at both ends when the portable acoustic device 300 is worn. In this case, since the curvature of the support body 310 changes gently, it is determined that the user intends to use the portable acoustic device 300, and the power of the portable acoustic device 300 is turned on or synchronized with the external terminal.

The curvature after the change of the curvature of the support body 310 in the displacement sensor can be taken into consideration in order to more accurately determine whether the user wore the wristwatch or whether it was worn on the portable wristwatch. When the curvature of the support body 310 is largely changed to the first size and then the curvature is fixed to a curvature of a second size that is gentler than that of the portable acoustic device 300, It is possible to judge that it is worn on.

In addition to the displacement sensor, a sensor such as a temperature sensor, a light sensor, or a heart sensor is provided on a wear surface of the wearer when the wearer worn the wearer's body, so that the temperature is in a person's body temperature range or brightness is darkened. The power of the portable audio-visual device 300 may be turned on, or the wireless communication unit 385 may be activated to synchronize with the external terminal.

Or a switch that is pressed in a physical manner so that the protruding switch is pressed to generate an ON signal when the user wears the switch. When the switch ON state is maintained for a predetermined time or more, the portable sound device 300 is powered on or synchronized with the external terminal .

The sensing unit 375 and the plurality of switches may be provided to accurately determine whether the sensing unit 375 is worn by combining a plurality of values.

The entire body 320 coupled to both ends of the support body 310 includes an upper case 321 and a lower case 324 and a main body 320 is interposed between the upper case 321 and the lower case 324, 381, a wireless communication unit 385, a battery 391, a microphone 360, and a rotation module 350 are mounted.

The full-length body 320 is manufactured by injection molding a polymer material. For example, a plastic product having strength such as polystyrene may be used. It may partially include a release material such as metal, glass, or leather.

The entire body 320 may be formed of a rigid polystyrene (PS) material to protect the internal parts and at the same time, polyurethane coating may be applied to the surface of the entire body 320 so as to be in close contact with the user's body. When the polyurethane coating is applied to the surface of the full-length body 320, a unified appearance of the portable audio-visual equipment 300 can be formed, and both the supporting body 310 and the full-length body 320 are in close contact with the user's skin, And it has the advantage of excellent fit.

Since the portable audio device 300 worn on the body is easily exposed to moisture such as sweat, the durability can be increased by adding a waterproof function. It is possible to form a rib that covers a gap between the upper case 321 and the lower case 324 or to prevent water from penetrating through the waterproof member. The upper case 321 and the lower case 324 can be brought into close contact with each other even if a separate waterproof member is not provided.

The main board 381 mounted in the electric vehicle body 320 of the present invention includes a battery 391, a user input unit 370, a sound output unit 340 ) And the like. Parts mounted on the full length body 320 may be provided symmetrically to the full length body 320 on both sides or asymmetrically. Parts provided only in the one electric field body 320 can be used through signal lines mounted on the support body 310. [ For example, when the wireless communication unit 385 is provided on one side of the full body 320, the wireless communication unit 385 can transmit the received acoustic signal to the earbuds 340 on both sides using signal lines.

The wireless communication unit 385 may include an antenna pattern 386 mounted on the main substrate 381 or formed on the surface of the full body 320 to transmit and receive signals to / from an external terminal. A control signal and an acoustic signal are received from an external terminal by synchronizing with an external terminal using a local wireless communication method such as an external terminal and Bluetooth or input through a user input unit 370 or a microphone 360 of the portable acoustic apparatus 300 And transmits the received control command and sound signal to the external terminal.

The user input unit 370 of the full-length body 320 may include a power button for turning on / off the power, a button for playing or talking, and a direction key for controlling the sound It may be used to control reproduction of a tune). The button may be a dome key that is physically pressed, or may be a touch key that senses a change in capacitance.

In the case of the touch key, the position is not limited, and the surface of the full length body 320 can be variously used. When the touch key is implemented on the surface of the full length body 320, the touch key position and function can be displayed using the LED at the portion where the touch key is implemented on the surface of the full length body 320.

The earbud 340 is inserted into a user's ear to transmit sound and the earbud 340 is connected to the main board 381 through an acoustic cable 345. The acoustic cable 345 may penetrate the full length body 320 and electrically connect the main board 381 and the ear bud 340. The sound output module (not shown) can perform a function of directly generating sound at the ear bud 340. The sound output module refers to a configuration including a diaphragm and the like.

The main board 381 controls the ear bud 340 to control the sound output according to the acoustic signal. The main board 381 provided at both ends of the support body 310 is connected to a signal line 3811 to transmit / receive signals or to transmit / receive electric power.

The acoustic cable 345 passes through the full-length body 320 and is electrically connected to the earbud 340 at one side and to the main board 381 at the other side to transmit acoustic signals. The acoustic cable 345 may be drawn from the full-length body 320 or into the full-length body 320.

4 is a partially exploded perspective view of a portable acoustic device 300 according to another embodiment of the present invention.

The support body 310 includes a shape memory alloy 311, an upper jacket 312, a lower jacket 313, an inner jacket 314, a wire bracket 315 and a connection 316.

The shape memory alloy 311 has a property of restoring to a specific shape even if it is deformed. When the user applies force to open the body, the shape memory alloy 311 returns to the original shape even if the support body 310 is deformed. Thereby preventing deformation or damage of the shape of the portable acoustic device 300.

The support body 310 further includes a covering portion 312, 313 and 314 surrounding the shape memory alloy 311. The covering portions 312, 313 and 314 are formed of thermoplastic polyurethane, Can be used. The thermoplastic polyurethane can be produced by dissolving in heat, and when hardened, has oil resistance, abrasion resistance, and elasticity like rubber.

The upper cover 312 and the lower cover 313 may be coupled to each other to form the appearance of the portable acoustic device 300. For this reason, the top cover 312 and the bottom cover 313 may have relatively small resilience and large stiffness compared to the inner cover 314.

The inner coating 314 can be coupled to the shape memory alloy 311 in a dual injection manner.

The inner cover 314 is formed of a shape memory alloy 311 for accurately positioning the position of the shape memory alloy 311 on the connection portion 315 and for fixing a signal line 3811 for transmitting or receiving signals or electric power of the full length body 320 on both sides, And the signal line 3811, as shown in Fig. Both ends of the inner cover 314 can be engaged with the pair of wire brackets 315.

The shape memory alloy 311 is exposed at both ends of the inner cover 314 and can be coupled to the wire bracket 315. [ The shape memory alloy 311 may be formed such that both end portions thereof are bent into a hook shape in order to increase the fixing force.

The wire bracket 315 provides a counterpart for stably fixing the signal line 3811 and provides a counterpart for providing a connection portion 316 to be described later. The wire bracket 315 can be coupled in the form of wrapping the top cover 312 and the bottom cover 313.

One region of the connection portion 316 may overlap with the support body 310 and the other region may overlap with the full body 320 to form a region to which a hinge 331 described later is coupled.

The entire body 320 is repeatedly folded and unfolded repeatedly with respect to the support body 310. Therefore, the durability of the connection portion 316 provided at the boundary is required to be high and a structure for firmly fixing the connection portion 316 is required Do.

The connecting portion 316 may be provided in a form of a combination of a hinge bracket 3161 to which the hinge 331 is coupled and a fixing bracket 3162 to be coupled to both sides of the hinge bracket 3161. The hinge bracket 3161 allows the hinge 331 to be easily engaged and the durability of the high connection portion 316 can be ensured by the engagement of the fixing bracket 3162. [

The hinge bracket 3161 may be made of a material having elasticity for coupling with the hinge 331. [ The hinge bracket 3161 is stretched to a certain extent when the hinge 331 is engaged, and after the hinge 331 is engaged, the hinge 331 is again narrowed by the elasticity so that the hinge 331 is not retracted again. The hinge bracket 3161 may be made of plastic, especially POM, to provide elasticity.

The connecting portion 316 may be formed of an integral type of injection molding. In this case, the connection portion 316 may be formed as a combined shape of the hinge bracket 3161 and the fixing bracket 3162, and the whole may be made of the POM material.

The connection portion 316 is fixed primarily by the wire bracket 315 and can be fixed by securing the top cover 312 and the bottom cover 313 to be firmly fixed.

One remaining area of the connection part 316 may be enclosed by the full length body 320. The upper case 321 and the lower case 322 may cover one side and the other side, respectively, of the other area of the connecting portion 316.

5 is a perspective view of a hinge 331 and a signal line 3811 passing through the hinge 331 according to an embodiment of the portable acoustic device 300 related to the present invention.

Refer also to Fig. 6 for convenience of explanation.

The signal line 3811 connects the electric parts provided at both ends of the support body 310 and can transmit and receive signals or electric power. The signal line 3811 may be introduced into the support body 310 through the hinge 381 in the full-length body 320.

The hinge 381 is provided at an end of the full-length body 320 and has a path through which the signal line 3811 passes. The hinge 381 can be rotatably coupled to the end of the support body 310.

Specifically, the hinge is mounted on the inside of the support body 310 and includes a body 3311 forming a body, a protrusion 3312 protruding from both sides of the body 3311 and coupled with the support body 310 to form a rotation axis, And a hinge hole 3313 formed in the area between the signal lines 3811 and 3312 and through which the signal line 3811 is discharged.

The hinge hole 3313 may be opened along the rotation plane of the support body 310 to communicate with the rotating support body 310. This is to prevent the hinge hole 3313 from being opened in one direction when the electric field body 320 is rotated to break or break the signal line 3811.

When the full length body 320 is rotated by the hinge 331 between the first state and the second state at an angle different from that of the support body 310, the hinge hole 3313 is rotated in the first direction in the first state And the second direction in the second state, and can be in continuous communication with the rotating supporting body 310. [

When the rotational angle of the supporting body 310 and the full-length body 320 is determined, the hinge hole 3313 is punched to correspond to the angle, thereby preventing the strength of the body 3311 from being weakened.

6 and 7 are perspective views of the connecting portion of the supporting body 310 and the electric body 320 from the outer side in a state in which the supporting body 310 is folded depending on the presence or absence of the outer closing portion 3314.

The full length body 310 can rotate between a state in which the whole body body 310 is straightly expanded in the vicinity of the supporting body 320 and the hinge 310 and a state in which it is folded inward. At this time, when the supporting body 310 or the full-length body 320 is folded inward, the signal line 3811 may be exposed from the outside, thereby deteriorating the appearance. In addition, it is possible to prevent the rotation of the body 310 or the full-length body 320 in which the foreign substance enters the space between the hinged holes 3313 opened to the outside, or to damage the signal line.

Accordingly, the hinge 310 may include an outer closing portion 3314 that prevents the signal line 3811 passing through the inside of the hinge 310 from being exposed from the outside. When the supporting body 310 and the full-length body 320 are rotated between the unfolded state and the inwardly folded state, there is no fear that the signal line 3811 is disconnected even if the outer closed portion 3314 is provided, It is possible to prevent the opening 3811 from being exposed in the outward direction.

8 to 10 are perspective views showing a structure in which the hinge 310 is inserted into the full length body 320 in a state in which the supporting body 310 is unfolded. Please refer to FIG. 6 for convenience of explanation.

The outer closing portion 3314 can prevent the signal line 3811 from being exposed in the folded state, but can not prevent the signal line 3811 from being exposed in the unfolded state. Therefore, the hinge 310 can be prevented from being exposed by inserting the support body 310 into the full length body 320 in the unfolded state. Hereinafter, the structure and mechanism will be specifically described.

The hinge 310 may be connected to a cylinder 332 mounted inside the electric field body 320 and may be provided at an end of the electric field body 320. At this time, the cylinder 332 can form a path passing through the signal line 3811 in a cylindrical shape.

The cylinder 332 may be formed in a cylindrical shape so that the electric-field body 320 surrounding the outside can form a circular or circular cross-section. This makes it possible to enhance the design completeness of the portable audio equipment.

However, the cylinder 332 is not limited to a cylindrical shape, but may be formed as a columnar structure that can be drawn out from the inside of the end of the electric field body 320 or drawn inward.

The full-length body 320 can be pulled out from the support body 310 and rotated to be folded or unfolded in the pulled-out state. The cylinder 332 has a hinge spring 333 having one end fixed to the cylinder 332 and the other end supporting the full length body 320 to form a restoring force to be pulled into the supporting body 310 when the full length body 310 is pulled out. Lt; / RTI >

The end of the supporting body 310 is drawn into the full length body 320 and the signal line 3811 passing through the hinge 331 and the hinge 331 is inserted into the full length body 320 together with the full length body 320 being unfolded Can be introduced. It is possible to prevent the signal line 3811 from being inserted into the full-length body and being exposed from the inside in the state where the full-length body 310 is unfolded.

More specifically, one end of the hinge spring 333 supports the support ring 334 fixed to the cylinder 332, and the other end supports the support bracket 323 provided at the end of the full-length body . The restoring force generated by the hinge spring 333 being compressed can be pulled inwardly to further push the support body 310 to the full length body 320 by pushing the support ring 334 and the support bracket 323.

11 and 12 are perspective views showing another embodiment of the body 3311 of the hinge 331. FIG. Please refer to Figs. 4 and 7 for convenience of explanation.

The body 3311 of the hinge 331 may be formed in a ball shape. The ball-shaped body 3311 is advantageous in that the thickness of the support body 310 can be reduced by occupying a minimum volume in which the support body 310 rotates.

Specifically, the support body 310, in particular, the connection portion 316 may form a hinge bracket 3161 to which the hinge 331 is coupled. The hinge bracket 3161 may be formed to correspond to the shape of the hinge 331. That is, the hinge bracket 3161 may have a spherical shape corresponding to the ball-shaped body 3311.

In addition, the body 3311 of the hinge 331 may include a plurality of angled surfaces. That is, the body 3311 of the hinge 331 is not limited to the ball shape but may be formed in a polygonal shape.

At this time, the hinge bracket 3161 corresponding to the body 3311 may also include a plurality of surfaces. At this time, the hinge bracket 3161 may have elasticity or may have a structure capable of moving to a certain distance inside. The support body 310 may be configured to be folded or unfolded when the user applies a force exceeding a predetermined level.

This allows the support body 310 to remain in the collapsed state despite the restoring force of the spring.

A plurality of surfaces of the body 3311 of the hinge 331 may be inclined at different angles along the rotation direction of the support body 310 to adjust the angle of the folding of the support body 310 and the full body 320 .

That is, the support body 310 can be fixed at a predetermined angle with the full body 320 even when the support body 310 is not fully extended or completely folded.

Specifically, the body 3311 of the hinge 331 may be a polygonal column having an axis coinciding with the rotational axis of the projection 3312. [

13 is a perspective view showing another embodiment including a contact portion 3163 for adjusting the angle at which the support body 310 or the full-length body 320 is folded.

The support body 310 may have a contact portion 3163 which contacts an end portion of the electric field body 320 in a state where the end portion of the support body 310 is folded. At this time, the contact portion 3163 may protrude inward and may sink into the support body 310.

The support body 310 may have a different angle of the folded state by varying the degree of protrusion or the degree of depression of the contact portion 3163.

The structure in which the contact portion 3163 protrudes inward of the support body 310 in the structure in which the support body 310 is drawn into the end portion of the electric field body 320 by the restoring force of the hinge spring 333 is preferable I can not. The contact portion 3163 is caught by the case constituting the full length body 320 and can interfere with the entry of the supporting body 310.

Accordingly, the contact portion 3163 may protrude from the inner end of the full-length body 320 toward the support body 310, or may be recessed in the opposite direction. At this time, the end of the support body 310 may have a depressed shape to engage with the protruding contact portion 3163.

When the contact portion 3163 is formed on the full length body 320, the maximum folding angle can be adjusted without interfering with the pulling of the support body 310. [

The contact part may include a sensor for transmitting or sensing an electrical signal when the contact part contacts the full body 320 or the support body 310 in a collapsed state. This allows the user to perceive the folded condition, limit some functions of the portable acoustic device, recognize the unfolded condition, and signal the specific function to operate.

The foregoing detailed description should not be construed in all aspects as limiting and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.
