  FIG. 2 is a top view schematically showing the structure of the glasses 100 according to an embodiment of the present invention, and FIG. 3 is a side view thereof. 2 and 3 together, each temple 120 defines the front end of the temple 120 and also defines the front end 121 attached to the back surface of the armor 115 by the hinge 116 and the rear end of the temple 120. The rear end portion 122 and the elastic deformation portion 123 disposed between the front end portion 121 and the rear end portion 122 are provided.

  As is clear from FIGS. 1 and 2, in each temple 120, a bone conduction speaker 124 is attached to the inner surface in the x-axis direction of the rear end portion 122. The bone conduction speaker 124 is a piezoelectric speaker that uses the mechanical natural resonance phenomenon of piezoelectric ceramics, and transmits sound vibrations to the cartilage near the ear of the wearer of the glasses 100 to listen to the wearer. Can do. Since the structure of the bone conduction speaker 124 is well known, a detailed description thereof is omitted here. In another embodiment, the bone conduction speaker 124 may be detachable from the rear end portion 122.

  FIG. 4 is a partial perspective side view schematically showing the structure of one temple 120 of the glasses 100 according to the embodiment of the present invention. As shown in FIG. 4, a board 125 that controls wireless communication with an external device (not shown) and a power source that supplies power to the board 125, that is, a battery 126, are incorporated in the front end 121. The substrate 125 is, for example, a flexible printed circuit board. In the present embodiment, the battery 126 is disposed on the rear end side of the temple 120 with respect to the substrate 125 having a smaller weight.

  The substrate 125 and the bone conduction speaker 124 are connected by a pair of wires 127 and 127. As will be described later, the audio signal from the external device is converted into an analog signal by the substrate 125, the converted analog signal is amplified, and then the amplified analog signal is sent to the bone conduction speaker 124 via the wires 127 and 127. Is output. The bone conduction speaker 124 generates vibration according to the analog signal, and this vibration is transmitted to the bone of the wearer of the glasses 100, so that the wearer can hear the sound of the audio signal.

  The front end portion 121 is made of a synthetic resin material such as acetate, like the frame 110 described above, and has a predetermined rigidity. The substrate 125 and the battery 126 may be embedded in the front end portion 121. A power switch 128 and a connector 129 are disposed on the lower surface of the front end 121. The power switch 128 can control on / off of power supply from the battery 126. The connector 129 is a connector that can be connected to, for example, a micro USB connector for charging the battery 126.

  The rear end portion 122 is formed of a synthetic resin material such as acetate, like the frame 110 and the front end portion 121 described above, and has a predetermined rigidity. As described above, the bone conduction speaker 124 is attached to the inner surface of the rear end portion 122. In this embodiment, the bone conduction speaker 124 is fixed to the rear end portion 122, but in other embodiments, the bone conduction speaker 124 may be detachable from the rear end portion 122.

  The elastic deformation portion 123 is attached to the rear end surface of the front end portion 121 at one end and supported by the rear end portion 122 at the other end, and covers the core member 130 and contours of the front end portion 121 and the rear end portion 122. And an elastic member 131 having a contour extending continuously from. The core member 130 extends substantially along the longitudinal direction of the temple 120. In this embodiment, the elastic deformation portion 123 is fixed to the rear end surface of the front end portion 121. However, in another embodiment, the deformation portion assembly formed from the elastic deformation portion 123 and the rear end portion 122 is a front end portion. It may be detachable from 121.

  For the core member 130, for example, a spring stainless steel wire (JIS G4314) having spring properties is used. On the other hand, an elastic resin material such as rubber is used for the elastic member 131. In the present embodiment, an elastic resin material that is easier to deform than the core member 130 is used for the elastic member 131. The core member 130 is disposed, for example, in a through hole (not shown) formed in the elastic member 131, and the wirings 127 and 127 described above are formed above and below the through hole for the elastic member 131. It arrange | positions in another through-hole (not shown), respectively.

  In the present embodiment, the rear end portion 122 can be held against the elastic deformation portion 123 at a plurality of rotation angle positions around the rotation axis A along the longitudinal direction of the temple 120. FIG. 5 is a partially enlarged perspective view schematically showing the structure of the rotation mechanism 140 that realizes the rotation of the rear end portion 122. As shown in FIG. 5, the rotation mechanism 140 is incorporated in the elastic deformation portion 123 and the rear end portion 122. The rotation mechanism 140 includes a first member 150 that is fixed to the rear end of the elastic deformation portion 123, and a second member 160 that is fixed to the front end of the rear end portion 122 and meshes with the first member 150.

  FIG. 6 is a partially enlarged perspective view schematically showing the structure of the rotation mechanism 140 according to one specific example. Referring also to FIG. 6, the first member 150 includes a cylindrical body 151. The central axis of the cylindrical body 151 coincides with the rotation axis A. One end surface 152 of the cylindrical body 151 defined in the direction along the central axis of the cylindrical body 151 is embedded and fixed in the rear end surface of the elastic deformation portion 123. For example, an adhesive or the like is used for fixing. The other end surface 153 of the cylindrical body 151 is disposed in the front end surface of the rear end portion 122. However, the cylindrical body 151 is not fixed to the rear end portion 122, and the second member 160, that is, the rear end portion 122 can be displaced with respect to the first member 150, that is, the elastic deformation portion 123, as will be described later.

  For example, a cylindrical protrusion 154 having the same central axis as the central axis of the cylindrical body 151 protrudes from the one end surface 152 of the cylindrical body 151 of the first member 150 into the cylindrical space in the cylindrical body 151. For example, a plurality of first teeth 155 having a triangular shape are formed around the central axis of the protrusion 154 at a distal end of the protrusion 154.

  On the other hand, the second member 160 includes a cylindrical body 161 disposed in a columnar space in the first member 150, and the cylindrical body 161 has the same central axis and the same as the protruding portion 154 of the cylindrical body 151. It has an outer diameter. At one end of the cylindrical body 161 facing the protruding portion 154 of the cylindrical body 151, for example, a plurality of triangular second teeth 162 are formed around the central axis of the cylindrical body 161 at the same interval as the plurality of first teeth 155. ing. The plurality of second teeth 162 mesh with the plurality of first teeth 155.

  As is clear from FIG. 6, a part of the outer peripheral surface of the cylindrical body 161 is cut away, and the cylindrical body 161 includes, for example, a pair of supports 163 and 163. An elastic body 164 such as a coil spring is disposed in the cylindrical body 161, and one end of the elastic body 164 is received by the end surface 165 in the cylindrical body 161, and the other end of the elastic body 164 is in addition to the cylindrical body 151. The end surface 153 is received. The pair of supports 163 and 163 may be formed only in the minimum necessary region where the elastic body 164 can be held in the cylindrical body 161.

  The front ends of the pair of support bodies 163 and 163 protrude into the rear end portion 122 through a pair of openings 156 and 156 formed in the other end surface 153 of the cylindrical body 151, respectively, and the front ends of the pair of support bodies 163 and 163 Is fixed to the rear end 122 at the protruding portion. For example, an adhesive is used for fixing. Each opening 156 extends in the circumferential direction around a central axis of the cylindrical body 161 over a predetermined angle range of, for example, less than 90 °.

  The elastic body 164 exhibits an elastic restoring force so as to keep the tip of the cylindrical body 161 away from the other end surface 153 of the cylindrical body 151. Due to the action of the elastic restoring force, the plurality of second teeth 162 of the elastic body 164 of the second member 160 are engaged with each other while being pressed against the plurality of first teeth 155 of the protruding portion 154 of the first member 150. At this time, the front end surface of the rear end portion 122 is in contact with the rear end surface of the elastic deformation portion 123. In this way, the rear end portion 122 is held at a predetermined rotational angle around the rotation axis A with respect to the elastic deformation portion 123.

  When the wearer holds the rear end portion 122 with a finger and displaces the rear end portion 122 back along the rotation axis A against the elastic restoring force of the elastic body 164, it is shown in FIGS. As described above, the front end surface of the rear end portion 122 is separated from the rear end surface of the elastic deformation portion 123. At the same time, the plurality of second teeth 162 of the cylindrical body 161 are released from meshing with the plurality of first teeth 155 of the protrusion 154. In this way, rotation of the rear end portion 122 around the rotation axis A relative to the elastic deformation portion 123 is allowed. At this time, further elastic restoring force is accumulated in the elastic body 164.

  When the wearer rotates the rear end portion 122 about the rotation axis A by a predetermined rotation angle and then returns the rear end portion 122 to the original position toward the elastic deformation portion 123, the plurality of first members of the cylindrical body 161 are moved. The two teeth 162 mesh with the plurality of first teeth 155 of the protrusion 154 again. Thus, the rear end portion 122 can be held at a rotation angle position different from the rotation angle position described above with respect to the elastic deformation portion 123 around the rotation axis A. As described above, since the opening 156 extends only within a predetermined angle range around the central axis of the cylindrical body 161, the rear end 122 does not rotate 360 ° with respect to the elastic deformation portion 123.

  Note that the core member 130 and the wires 127 and 127 of the elastically deformable portion 123 may be disposed so as to pass through holes (not shown) formed along the respective central axes of the cylindrical body 151 and the cylindrical body 161. Good. Since the wiring 127 and 127 have a certain length of margin, the wiring 127 and 127 are cut even if the rear end portion 122 rotates around the rotation axis A with respect to the elastic deformation portion 123. There is nothing.

  In the present embodiment, the structure of one temple 120 described above is also provided in the other temple 120 in the same manner. However, the structure of the other temple 120 is symmetrical to the structure of the one temple 120.

  FIG. 9 is a block diagram of a control system of the glasses 100 according to an embodiment of the present invention. In the glasses 100, one temple 120 constitutes a master and the other temple 120 constitutes a slave. For example, the master-side temple 120 includes a control unit 200, an audio signal generation unit 201, a wireless communication unit 202, and a microphone 203 that are formed on the substrate 125. A battery 126 is connected to the substrate 125, and a bone conduction speaker 124 is connected to the audio signal generator 201.

  The control unit 200 includes, for example, a processor and a memory, and executes various processes in the temple 120. Specifically, the processor executes various processes by reading instructions from an application program or the like stored in a memory which is a nonvolatile memory, for example. An audio signal generation unit 201, a wireless communication unit 202, and a microphone 203 are connected to the control unit 200, respectively.

  The wireless communication unit 202 can send and receive audio signals to and from an external device (not shown). Transmission / reception of audio signals is established according to a short-range wireless communication standard such as Bluetooth (registered trademark). The wireless communication unit 202 can also establish data communication with the wireless communication unit 202 of the other temple 120. This data communication includes, for example, communication of an audio signal, communication of a command relating to power off, and the like.

  The audio signal generation unit 201 has functions of a D / A converter and an amplifier. Specifically, the audio signal generation unit 201 converts an audio signal received from an external device into an analog signal. The converted analog signal is amplified. Thereafter, the amplified analog signal is output from the audio signal generation unit 201 to the bone conduction speaker 124. The external device includes, for example, a mobile phone terminal, a music playback device, and other information processing terminals.

  In this embodiment, the wireless communication unit 202 is provided in both the master temple 120 and the slave temple 120. However, for example, only the wireless communication unit 202 of the master temple 120 receives an audio signal from an external device. Is called. The received audio signal may be transmitted from the master wireless communication unit 202 to the slave wireless communication unit 202. For example, when the power switch 128 of one of the temples 120 is turned off, a command is communicated through the wireless communication unit 202 so that the power switch 128 of the other temple 120 is also turned off.

  The microphone 203 acquires the wearer's voice. The acquired audio signal is amplified and converted into a digital signal and input to the control unit 200. The microphone 203 is used, for example, to issue a command by voice input to the control unit 200. In addition, the microphone 203 is used as a hands-free microphone during a call via an external device such as a mobile phone terminal. Noise cancellation may be performed on the sound acquired by the microphone 203. Note that the slave temple 120 does not have to be provided with the microphone 203.

  Next, a scene in which the glasses 100 of the present embodiment are used is assumed. When the wearer turns on the power switches 128, 128 of both the temples 120, 120, the glasses 100 start communication with the wearer's mobile phone terminal, for example. When music is played on the mobile phone terminal, an audio signal is received through the wireless communication unit 202 of the temple 120 on the master side. The analog signal converted and amplified by the audio signal generation unit 201 is output to the bone conduction speaker 124, and the wearer can hear the music.

  When the communication with the mobile phone terminal is completed, the wearer turns off the power switch 128 of one of the temples 120. Along with this turn-off processing, a power-off command is transmitted from the wireless communication unit 202 of one temple 120 to the wireless communication unit 202 of the other temple 120, and the power switch 128 of the other temple 120 is also turned off. Thus, the processing in the glasses 100 ends. The above processing is the same when, for example, a call is made on a mobile phone terminal.

  According to the glasses 100 as described above, since the elastically deformable portion 123 that can be elastically deformed is disposed between the front end portion 121 and the rear end portion 122 of the temple 120, the elastic deformation of the elastically deformable portion 123 causes a bone to be formed on the head. The conductive speaker 124 can be reliably pressed. As a result, the wearer of the glasses 100 can hear a high quality sound. Moreover, since the board | substrate 125 and the battery 126 with which the wireless communication part 202 is established are integrated in the front-end part 121, the appearance as eyewear can be maintained.

  In addition, in the temple 120, the battery 126 having a greater weight is disposed behind the substrate 125 having a smaller weight, so that the center of gravity of the temple 120 can be disposed more rearward. As a result, the center of gravity of the temple 120 can approach the wearer's ear. Therefore, compared with the case where the battery 126 is disposed in front of the substrate 125, it is possible to reliably avoid the glasses 100 from being displaced forward. Further, since the battery 126 which is a heavy object is on the temple 120 side, the heavy object is arranged at a position close to the center of gravity of the spectacles 100, so that a sense of stability at the time of wearing the spectacles 100 is increased.

  In addition, since the circuit board 125 and the battery 126 are laid out on each of the temples 120 and 120 and data can be transmitted and received between the temples 120 and 120 by wireless communication, the temples 120 and 120 are connected to each other. There is no need to arrange the wiring on the frame 110. Therefore, since the temples 120 and 120 can be used in common for the frames 110 of various variations, it is possible to select the frame 110 according to the wearer's preference.

  Furthermore, in another embodiment, the bone conduction speaker 124 is detachable with respect to the rear end portion 122, or the deformation portion assembly formed of the elastic deformation portion 123 and the rear end portion 122 is with respect to the front end portion 121. Detachable. In this case, the bone conduction speaker 124 can be removed or the deformable part assembly can be replaced with another deformable part assembly according to the wearer's preference, the situation in which the glasses 100 are used, and the application. As a result, the range of design of the glasses 100 and the selection of the design can be expanded.

  Moreover, the rotation mechanism 140 of the rear-end part 122 is incorporated in the glasses 100 of this embodiment. According to the rotation mechanism 140, the rear end portion 122 can be rotated around the rotation axis A with respect to the elastic deformation portion 123 and can be held at a predetermined rotation angle. As a result, the rear end 122 can be rotated in accordance with the shape of the wearer's head, so that the bone conduction speaker 124 attached to the rear end 122 can be reliably pressed by the wearer's head. .

  In the glasses 100 as described above, the wires 127 and 127 may be disposed in the through hole for the core member 130 instead of the other through hole described above. In this case, the wires 127 and 127 may be wound around the core member 130 or may be bonded to the core member 130. In addition, a through hole for the core member 130 and a through hole for the wires 127 and 127 may be connected.

  Although the present invention has been described above, the technical scope of the present invention is not limited to the scope described in the above embodiment. It will be apparent to those skilled in the art that various modifications or improvements can be made to the above embodiment. It is apparent from the scope of the claims that the embodiments added with such changes or improvements can be included in the technical scope of the present invention.
