Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a band assembly for a smart watch having a band touch sensor,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a band assembly for a smart watch, and more particularly, to a smart watch band assembly in which a user can easily select a function of a smart watch.

Popularized smart phone integrates data communication functions such as schedule management and Internet access to mobile phone functions. Unlike conventional mobile phones, which have been released as finished products and have been used only for a given function, It can be installed, added or deleted as desired.

However, increasingly high specifications are required to implement various functional applications, and the size and weight of smartphones are becoming significant.

On the other hand, as the size and weight increase, mobility and convenience are deteriorating. For example, in a bag or a pocket, it is difficult to use in real time, and the user may not be able to recognize a message or a phone call. In addition, as the size increases, it is often difficult to use when it is necessary to avoid meeting or eyes of another person.

In recent years, smart watches have been introduced that can be worn in places where accessibility is good, such as the end of a wrist or the sleeve of a wrists.

Such a smart watch can provide basic functions such as a simple phone call, confirmation of message reception, and voice reproduction from a time check, and the above functions are provided by smart watch itself or in a manner of being linked with a smart phone. Therefore, recently, it is attracting attention as a device that can complement the mobility and convenience of a somewhat deteriorated smartphone.

In addition, a separate touch sensor is provided on the display of the smart watch for visually confirming the time, telephone, and message reception, thereby generating an electrical signal corresponding to a user's touch or scroll operation, Can be implemented.

However, since the touch sensor itself of the smart watch is relatively small in size, it is difficult for the user to perform a delicate touch operation, and errors are likely to occur in touch, scroll, and drag operations.

The touch sensor provided on the display of the smart watch has a small area. Accordingly, the present invention provides a smart watch band assembly that is free from input errors and limitations such as touch sensitivity, touch, and scrolling operations falling due to a narrow area.

There is also provided a smart watch band assembly capable of improving the inconvenience of screen closure of a smart watch by performing a touch, a scroll and a drag operation on a touch sensor on a smart watch.

The present invention provides a smart watch band assembly capable of binding a smart watch to a binding object.

The present invention provides a smart watch band assembly that improves the sound transmission capability of a smart watch.

The present invention provides a smart watch band assembly that can be easily recognized by a user in a reception situation such as a phone call and a message of a smart watch.

According to an exemplary embodiment of the present invention, a smart watch band assembly on which a smart watch is mounted comprises an acoustic module for receiving an electrical signal from a smart watch to generate sound, a sound module integrated with the sound module, A cradle, a watch band for binding the cradle to the object to be bound, and a watch band, provided on the outer surface of the watchband, for detecting a first band contact signal of the object, And a smart watch may implement a function corresponding to an electrical signal received from the first band touch sensor.

The smart watch in this specification may include a speaker or a display as an audiovisual means and touch sensors placed on the display and capable of sensing touch positions of an object (e.g., a user's fingertip or a touch pen) , A basic clock and alarm function, etc., and may itself include a reception function such as a telephone and a message, or may provide functions such as voice and video reproduction. In some cases, it is possible to refer to a clock-shaped device capable of providing some functions of a smartphone in cooperation with a smartphone. In addition, the smart watch can basically include an input / output terminal for charging its own battery or transmitting / receiving data.

In general, a touch sensor is provided on the screen of a smart watch that is used to improve the accessibility of a smartphone that gradually decreases in size and weight, and a user can transmit an electrical signal generated by touching the touch sensor to the smart watch , The smart watch may implement a function corresponding to the electrical signal (e.g., receiving a call, confirming a message, or playing music).

However, since the touch sensor itself of the smart watch has a relatively small area, it is difficult for the user to perform a delicate touch operation, and it is difficult to clearly distinguish the touch, the scroll, and the drag operation on a narrow area.

Accordingly, in the present invention, the first band touch sensor is provided on the outer surface of the watch band, and instead of the touch sensor on the narrow smart watch, an electrical signal for implementing the smart watch function is transmitted on the first band touch sensor to the outer surface of the band, And can be free from input errors or restrictions such as scrolling operations.

Furthermore, if the touch sensor on the smart watch carries out a touch, scroll and drag operation, it is difficult to pick up a desired function by the screen of the smart watch. However, when the scroll and drag operations are performed on the first band touch sensor The screen of the SmartWatch is not covered, so the user can accurately pick out the desired function of the SmartWatch.

The first band contact signal may correspond to any one of the touch retention, the one touch, the repeated touch, and the scroll operation. Here, the touch retention operation refers to a state in which the object touches the first band touch sensor over a predetermined period of time And the one-touch operation may mean that the object touches and falls on the first band touch sensor over a specific time, and the repeated touch operation may mean that the one-touch operation is repeated twice or more. The scroll operation may mean an operation in which an object passes over a specific section on the screen.

Further, a second band touch sensor for sensing a second band contact signal of the object on the outer surface of the watch band and transmitting an electrical signal corresponding to the second band contact signal to the smart watch may be further arranged.

The first and second band touch sensors may be securely provided at a predetermined distance apart, but preferably disposed between the cradles.

When a second band touch sensor is added, the smart watch can implement a function corresponding to an electrical signal received from the first band touch sensor and the second band touch sensor.

For example, the electrical signal received from the first band touch sensor and the second band touch sensor may be any one of the touch retention, the one touch, the repeated touch, and the scroll operation of the first band touch sensor, Touch holding, one-touch, repeated touch, and scroll operation.

In particular, the electrical signal received from the first band touch sensor and the second band touch sensor can correspond to a combination of the touch operation of the first band touch sensor and the scroll operation of the second band touch sensor, thereby performing a general drag operation It becomes very easy to do. The electrical signals received from the first band touch sensor and the second band touch sensor may correspond to a combination of touch holding of the first band touch sensor and the second band touch sensor. This combination can control SmartWatch to connect directly to an emergency phone, such as 112 or 119, in an uncommon combination.

A smart watch can be detachably mounted to the cradle, and a smart watch mounted on the cradle is secured to the cradle. As a means for fixing the smart watch to the cradle, an interference fit, a hook structure, a clip structure, a bolt, etc. can be applied.

In addition, the cradle is equipped with a sound module, which receives the electrical signal generated by the smart watch during a call, message reception, or alarm operation to generate sound. A typical SmartWatch will have a built-in speaker, but if you do not have a built-in speaker, the sound module can perform basic speaker functions, and in some cases even if the built-in SmartWatch has its own speaker, The sound module can compensate it. Of course, the first and second band touch sensors may be provided on the smart watch at a predetermined interval, but are preferably disposed with the cradle therebetween.

The acoustic module includes, for example, a main piezoelectric driving body, a diaphragm physically coupled to the main piezoelectric driving body, and at least one of the main piezoelectric driving body and the diaphragm at a fixed point located inside the outer periphery of the main piezoelectric driving body And the outer periphery of the main piezoelectric driving body and the diaphragm can vibrate at a free end around the fixed point.

The main piezoelectric driving body and the diaphragm are integrally coupled to transmit the vibration of the piezoelectric driving body through the diaphragm and the supporting part supports the piezoelectric driving body or the diaphragm at a fixing point located inside the outer periphery of the piezoelectric driving body. In the present invention, the outer periphery of the piezoelectric ceramics is fixed in the conventional piezoelectric loudspeaker. However, in the present invention, the piezoelectric driving body and the diaphragm are supported at the central portion or the periphery thereof rather than the outer periphery, . Therefore, the piezoelectric actuator and the diaphragm of the present invention can further improve the low-band performance and can obtain characteristics similar to those of the conventional magnetic circuit type speaker, as compared with the conventional piezoelectric speaker.

In addition, the smart watch and the sound module may be directly connected to each other through the electric terminal, or may be electrically connected to the input / output terminal of the smart watch mentioned above in the cradle, So that the cradle can serve as an intermediary for electrically connecting the smart watch and the acoustic module to each other.

In addition, a smart watch has a vibration function provided by a general mobile phone or a smart phone, but it may be difficult for the user to recognize the vibration only by the vibration occurring in the smart watch itself. Accordingly, in the present invention, a separate vibration module may be further provided to compensate for this. The vibration module may be provided integrally with the cradle, and the vibration module may receive electrical signals from the smart watch to generate vibration. In general, the vibration function of the smart watch will be provided. However, in some cases, the vibration function may be provided in the band assembly, though it may be omitted for weight reduction or miniaturization of the product.

In addition, the smart watch band assembly according to the present invention may include a vibration transmission structure that vibrates the vibration generated by the smart watch in contact with the object to be bound, and transmits the amplified vibration to the object to be bound. For example, the vibration transmitting structure may include protrusions formed on the inner surface of the watchband, and the protrusions may be provided in a plurality of hemispherical shapes, line shapes, and the like.

The smart watch and the cradle can be bound to a binding object by a watch band, which can generally be the wrist of a user, and a user can be placed on the smart watch or cradle through the wrist, which is in direct contact with the above- The vibration generated in the vibration module can be easily recognized.

The smart band band assembly of the present invention provides a first band touch sensor on the outer surface of a watch band instead of a smart watch touch sensor which is difficult for a user to perform delicate touch operation due to its small area, It can be free.

In addition, when the touch sensor on the smart watch performs a touch or a scroll operation, the screen of the smart watch is covered. However, in the smart watch band assembly of the present invention, And scrolling operations so that the user can accurately pick out the desired function of the smart watch.

In addition, a second band touch sensor may be further added to implement a function corresponding to an electrical signal received from the first band touch sensor and the second band touch sensor. Particularly, it is very easy to perform a general drag operation by keeping the touch holding operation in the first band touch sensor and performing the scroll operation in the second band touch sensor.

In addition, the electrical signals received from the first band touch sensor and the second band touch sensor may correspond to a combination of touch holding of the first band touch sensor and the second band touch sensor, You can control the SmartWatch to connect directly to an emergency phone, such as 119. Here, the first band touch sensor and the second band touch sensor may be connected to the control module in the cradle, wherein the control module may include other electrical components (for example, a band touch sensor, a sound module , A vibration module, etc.), and the control module can be interlocked with a smart phone interlocked with the SmartWatch. In addition, the control module can be electrically connected to the display of the SmartWatch through the electrical terminal of the cradle or a touch sensor mounted on the display.

Further, the smart watch band assembly of the present invention can be easily bound to the binding object by the cradle and the watch band in which the smart watch is simply detached / attached.

In addition, the smart watch band assembly of the present invention can supplement the speaker volume of the smart watch itself, which is somewhat lacking, through an acoustic module that receives an electrical signal from a smart watch in response to a phone call, message reception or an alarm operation. A typical SmartWatch will have a built-in speaker, but if the built-in speaker is not available, the sound module may perform the basic speaker function.

In addition, the smart watch band assembly of the present invention provides a vibration module separate from the smart watch, thereby preventing the user from perceiving the vibration generated in the smart watch itself. In order to reduce the weight and miniaturize the product, In some cases, the vibration function may be missed, but in this case, the band assembly can provide a vibration function.

In addition, the smart watch band assembly of the present invention improves the vibration transmitting ability through the vibration transmission structure so that the user can easily recognize the vibration of the smart watch or the vibration module mounted on the cradle.

In addition, the acoustic module of the smart watch band assembly of the present invention overcomes the reproducible frequency of a conventional piezoelectric speaker, and can be reproduced even in high and middle bass.

The piezoelectric actuator 311 and the diaphragm 312 are supported by the support portion 314 at the center portion or the periphery thereof rather than the outer periphery thereof, So that the outer periphery can be a free end rather than a fixed end. Therefore, the piezoelectric driving body 311 and the diaphragm 312 of the present invention can further improve the low-band performance and can acquire characteristics similar to those of the conventional magnetic circuit type speaker.

As the main piezoelectric actuator 311, a PZT series or a PMN-PT (piezoelectric single crystal) in which PbO, ZrO 2 , and TiO 2 are mixed may be used. In addition, various materials using a piezoelectric effect may be used. The main piezoelectric actuator 311 may be provided in a flat plate shape or other flexible three-dimensional shape.

The diaphragm 312 physically coupled to the main piezoelectric actuator 311 can transmit energy to the air by receiving the vibration of the main piezoelectric actuator 311. The diaphragm 312 may be formed in a conical shape or a trumpet shape in addition to a simple plate shape. In addition to being in contact with the main piezoelectric drive body 311, the diaphragm 312 may also be in physical contact with points or lines. The diaphragm 312 may be formed of a metal plate, a synthetic resin, paper or the like, and in the case of metal, brass, aluminum, stainless steel, or an alloy thereof may be used.

The supporting portion 314 is connected to the main piezoelectric driving body 311 and the diaphragm 312 through the fixing point 313. [ The main piezoelectric driving body 311 and the diaphragm 312 are fixed by the supporting portion 314 and can oscillate about the fixed point 313 in response to the acoustic electrical signal. Here, the fixed point 313 may be defined at a central portion of the main piezoelectric actuator 311, that is, at one point inside the outer periphery thereof. As the acoustic electrical signal is applied, the fixing point 313 stops with respect to the supporting portion 314, and the outer peripheral portion of the main piezoelectric driving body 311 and the diaphragm 312 can vibrate up and down as free ends. The vibration of the main piezoelectric actuator 311 is transmitted to the diaphragm 312 to transmit sound energy to the air.
