In particular, a Bluetooth headset is a hand-free device which provides for wireless communication. Conventional techniques for a Bluetooth headset are disclosed in a U.S. Patent Publication Application No. 2011-0244927 (published on Oct. 6, 2011, and entitled “Apparatus and Method for Wireless Headsets”), and a Korean Patent Publication Application No. 10-2007-0055677 (published on May 31, 2007, and entitled “Wireless Headset”).
Referring to
The earpiece 11 of the Bluetooth headset 10 is mounted on wide-width surfaces 14a and 14b of the body 14. The body 14 includes a first body 12 on which the earpiece 11 is mounted, and a second body 13 coupled to the first body 12. In terms of a shape, the body 14 may include first and second surfaces 14a and 14b, which are the two wide-width surfaces 14a and 14b, along the longitudinal direction of the body 14, and a side surface 14c which has a narrow width between the first and second surfaces 14a and 14b. That is, in a state where the first body 12 and the second body 13 are coupled together, the body 14 is divided into the first and second surfaces 14a and 14b and the side surface 14c which defines the width of the first and second surfaces 14a and 14b. The earpiece 11 is provided on the wide-width surface of the first body 12, that is, the first surface 14a. On the second surface 14b on which the earpiece 11 is not mounted, a call and pairing button 21 is provided, and on the side surface 14c is positioned a power button of the Bluetooth headset 10 or a manipulation button 22 such as a transmission/reception ON/OFF button or a volume control button. If the manipulation button 22 mounted on the side surface 14c is mounted on the first surface 14a or the second surface 14b, a separate flexible circuit board (not shown) is provided for electric connection with the internal circuit board 15, such that the internal circuit board 15 and the manipulation button 22 are connected by the flexible circuit board. In particular, when the call and pairing key button 21 is positioned on one of the first surface 14a and the second surface 14b, it is generally connected with the internal circuit board 15 through the flexible circuit board due to problems in use.
However, the conventional Bluetooth headset has many drawbacks. For example, referring to the plane view of the Bluetooth headset 10 shown in
Furthermore, since the wide-width surfaces 14a and 14b are mounted on the ear, a sense of grip of the Bluetooth headset 10 is not good when the user grabs the Bluetooth headset 10 to wear or remove the Bluetooth headset 10 or manipulate buttons. Thus, when wearing or removing the Bluetooth headset 10, the user tends to grab a side surface portion of the Bluetooth headset 10, such that buttons on the side surface may erroneously operate.
Accordingly, the present invention provides a Bluetooth headset in which buttons are mounted on an internal circuit board and operate on the internal circuit board, and a button for controlling volume and a button for call and pairing are mounted on the same surface.
The present invention also provides a Bluetooth headset in which buttons are prevented from being mounted on a portion held by a user when the user wears or removes the Bluetooth headset, thus preventing erroneous operations of the buttons.
The present invention also provides a Bluetooth headset in which buttons provided in the Bluetooth headset are mounted on an internal circuit board, thereby simplifying assembly processing and reducing the cost.
According to an aspect of the present invention, a Bluetooth headset includes an earpiece and a body portion on which the earpiece portion is mounted, wherein the earpiece portion is formed to a side surface of the body portion so that a surface of the earpiece portion substantially greater than the side surface of the body portion.
According to another aspect of the present invention, there is provided a Bluetooth headset including an earpiece portion and a body portion on which the earpiece portion is mounted, wherein the earpiece portion is formed in a central-axis direction of the earpiece portion in which sound is emitted from the earpiece portion.
The above and other features and advantages of exemplary embodiments of the present invention will be more apparent from the following detailed description taken in conjunction with the accompanying drawings, in which:
Hereinafter, a Bluetooth headset according to the present invention will be described with reference to the accompanying drawings. For clarity and convenience of the description, thicknesses of lines or sizes of components shown in the drawings may be shown as being exaggerated. In addition, the same structure as in the display module fixing apparatus for the portable terminal described above will be referred to as the same reference numeral and a description thereof will be substituted by the above description.
Although ordinal numbers such as “first”, “second”, and so forth will be used in an embodiment described below, they are merely intended to distinguish objects having the same name, their order may be set arbitrarily, and the preceding description of an object may be applied to a next-order object. In addition, the following description will be made with reference to a central-axis direction of an earpiece portion (a direction in which sound is emitted, a front/rear surface direction of the earpiece portion, a Y-axis direction, and a horizontal direction), but this direction is merely a virtual direction which is set to easily recognize an installation position of each component of the Bluetooth headset, thus the reference direction may be freely changed. Moreover, the front surface of the Bluetooth headset indicates a portion through which sound of the earpiece portion is emitted, and such indication is intended to set a reference for description of the shapes or forms and structures of the earpiece portion and a body portion of the Bluetooth headset and thus may be freely changed.

Referring back to
The second body 122 is provided at the other side of the earpiece portion 110 with respect to the central axis (Y axis) of the earpiece portion 110. The second body 122 has a wide-width surface on the side surface of the Bluetooth headset 100. More specifically, the second body 122 has a wide-width surface defining the other side of the Bluetooth headset 100 and a curved surface portion which is bent from the wide-width surface to form the side surface of the body portion 120 together with the first body 121. On the curved surface may be formed a groove for exposing the buttons 150 or the connection terminals 170 provided along the side surface of the internal circuit board 130 to outside.
As shown in
The side surface of the internal circuit board 130 includes a power key 150 and/or a volume control key 150, and a call and pairing key 170. On the side surface of the internal circuit boar 130 are mounted not only the buttons 150, but also the connection terminals 170 for charging the battery 140 or inputting external information in such a way to be directly connected to the internal circuit board 130. Since the buttons 150 and the connection terminals 170 are directly connected to the internal circuit board 130, the assembly can be easily performed during manufacturing stage and thus a separate component such as a flexible circuit is not required, reducing the cost.
The buttons 150 are mounted spaced apart from the earpiece portion 110, and in particular, the call and pairing key 170 is formed spaced apart from the earpiece portion 110 on the side surface on which the earpiece portion 110 is mounted. Thus, when the user wears the Bluetooth headset 100 on the ear, the call and pairing key 170 cannot be seen from outside which in turn also improves the esthetic aspect of the Bluetooth headset 100. In the current embodiment, the call and pairing key 170 are mounted on the same plane as the side surface of the body portion 120 on which the earpiece portion 110 is mounted, and the volume control key 150 or the power key 150 is provided on a side surface facing the side surface on which the earpiece portion 110 is mounted. However, the positions of the buttons 150 are not limited thereto. In alternate embodiment, the buttons 150 may be mounted in any position of the body portion 120 in the current embodiment in which the earpiece portion 110 and the body portion 120 are disposed in the same axis direction, and the buttons 150 may also be mounted on the wide-width surface of the body portion 120 by using a separate flexible circuit.
On the wide-width surfaces of the first body 121 and the second body 122, more specifically, both side surfaces of the Bluetooth headset 100 may be further formed a grip surface (not shown) for allowing the user to easily hold the Bluetooth headset 100 and preventing slippage. The shape of the grip surface may be variously changed. For example, a plurality of protrusions may be formed on a portion gripped by the user or a separate member formed of a rubber material may be attached to the portion.
Referring to
The Bluetooth headset 100 structured as described above is provided with the battery 140 at a side of the internal circuit board 130 and the earpiece portion 110, the buttons 150, and the connection terminals 170 which are mounted along the side surface of the internal circuit board 130. As a result, when viewed from the front surface of the Bluetooth headset 100, the Bluetooth headset 100 has a shape as shown in
As is apparent from the foregoing description, the wide-width surface of the body portion of the Bluetooth headset is formed long in the central-axis direction of the earpiece portion, thus implementing a unique design which is different from the conventional Bluetooth headset discussed earlier.
The configuration according to the teachings of the present invention as described above address the drawbacks associated with the conventional headset. For example, the user can wear the Bluetooth headset on the ear or remove it from the ear while holding the wide-width surface of the Bluetooth headset, thus making it easy for the user to wear or remove the Bluetooth headset.
Moreover, the earpiece portion of the Bluetooth headset is mounted to protrude from the side surface of the wide-width surface of the body portion, and the buttons or connection terminals are mounted along the side surface, thereby realizing various designs of the Bluetooth headset and improving the esthetic aspect of the Bluetooth headset.
Further, the buttons or the connection terminals are mounted on the internal circuit board, thereby simplifying assembly and reducing the manufacturing cost.
