以下、図を参照して本発明を実施するための最良の形態を詳細に説明する。
(実施形態1)
図1から図3は本発明を適用した携帯電子機器の実施形態1の構成として折り畳み式携帯電話を示したもので、1は第1の筐体、2は第2の筐体、3は表示部、4は操作部、5はヒンジ部、6はパネルスピーカである。
Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings.
(Embodiment 1)
1 to 3 show a foldable mobile phone as a configuration of a first embodiment of a portable electronic device to which the present invention is applied. 1 is a first casing, 2 is a second casing, and 3 is a display. , 4 is an operation unit, 5 is a hinge unit, and 6 is a panel speaker.

第1の筐体は表示画面による表示部3を有する表示部筐体1であり、第2の筐体は各種操作キーによる操作部4を有する操作部筐体2であり、これら表示部筐体1及び操作部筐体2はヒンジ部5を介して折り畳み自在に結合されている。このヒンジ部5は、図示例では、表示部筐体1の一端部に設けたヒンジボス51を操作部筐体2の一端部に設けたヒンジボス52に不図示のヒンジ軸を介して結合し装着することで、折り畳み状態から図示のように縦(上下)に開放できるように構成されている。   The first casing is a display section casing 1 having a display section 3 by a display screen, and the second casing is an operation section casing 2 having an operation section 4 by various operation keys, and these display section casings. 1 and the operation part housing | casing 2 are connected via the hinge part 5 so that folding is possible. In the illustrated example, the hinge portion 5 is attached by connecting a hinge boss 51 provided at one end of the display unit housing 1 to a hinge boss 52 provided at one end of the operation unit housing 2 via a hinge shaft (not shown). Thus, it is configured so that it can be opened vertically (up and down) as shown in the figure from the folded state.

パネルスピーカ6は、表示部3の表示パネル31のヒンジ部5と反対側端部の内側面に貼り付けた圧電素子による振動部61と、この振動部61の振動に応じて音を発生する振動板としても機能する表示パネル31とから構成されている。なお、この表示パネル31は、その全周でラバーによるクッション材32を介して表示部筐体1に組み付けることで、パネルスピーカ6の振動板として機能する。   The panel speaker 6 includes a vibration unit 61 made of a piezoelectric element attached to the inner surface of the display panel 31 opposite to the hinge unit 5 of the display unit 3, and vibration that generates sound in response to the vibration of the vibration unit 61. The display panel 31 also functions as a plate. In addition, this display panel 31 functions as a diaphragm of the panel speaker 6 by assembling the display panel 31 to the display unit housing 1 through a rubber cushioning material 32 around the entire periphery.

以上によりパネルスピーカ6は、携帯電話に組み込まれたテレビ等のスピーカとして使用されるとともに、図1に示したように、携帯電話を縦に開いた状態で通話する際の報音部としても使用される。   As described above, the panel speaker 6 is used as a speaker for a television or the like incorporated in a mobile phone, and also used as a sound reporting unit when making a call with the mobile phone opened vertically as shown in FIG. Is done.

また、操作部筐体2には、携帯電話の折り畳み状態において、表示部筐体1の表示パネル31の全周囲に当接する一様な連続凸条による伝達部21が形成されている。この伝達部21は、図示例では、操作部筐体2に両面テープ42で貼り付けた操作キーパネル41を囲む形状となっている。なお、操作キーパネル41のヒンジ部5と反対側端部には、図示しないが、集音孔が形成されて、その内側にマイクが設けられる。   In addition, the operation unit housing 2 is formed with a transmission unit 21 having a uniform continuous ridge that contacts the entire periphery of the display panel 31 of the display unit housing 1 in the folded state of the mobile phone. In the illustrated example, the transmission unit 21 has a shape surrounding an operation key panel 41 attached to the operation unit housing 2 with a double-sided tape 42. Although not shown, a sound collection hole is formed at the end opposite to the hinge portion 5 of the operation key panel 41, and a microphone is provided inside the sound collection hole.

携帯電話の折り畳み状態において、前述したパネルスピーカ6の振動は、その振動板を兼ねた表示パネル31の全周囲に当接する伝達部21を介して操作部筐体2に伝達される。従って、パネルスピーカ6は、電話やメールの着信を知らせるバイブレータとしても使用される。   In the folded state of the mobile phone, the vibration of the panel speaker 6 described above is transmitted to the operation unit housing 2 via the transmission unit 21 that contacts the entire periphery of the display panel 31 that also serves as the diaphragm. Accordingly, the panel speaker 6 is also used as a vibrator for notifying incoming calls or mails.

以上、実施形態1の筐体のバイブレータ構造によれば、表示部筐体1に設けたパネルスピーカ6の振動を折り畳み時に操作部筐体2に伝達でき、すなわち、折り畳み式携帯電話において、バイブレータとスピーカとを共用化できる。従って、別途バイブレータを設けることなく、コストダウン、部品点数の削減、実装の省スペース化が図れる。   As described above, according to the vibrator structure of the casing of the first embodiment, the vibration of the panel speaker 6 provided in the display section casing 1 can be transmitted to the operation section casing 2 when folded. Can be shared with speakers. Therefore, it is possible to reduce the cost, reduce the number of components, and save the mounting space without providing a separate vibrator.

(実施形態2)

Part, 31 is a display panel, 32 is a cushioning material, 4 is an operation part, 41 is an operation key panel, 42 is a double-sided tape, 5 is a hinge part, 51 and 52 are hinge bosses, 6 is a panel speaker, and 61 is a vibration part. .

実施形態2は、パネルスピーカ6を、携帯電話の折り畳み状態において、操作部筐体2の操作キーパネル41の内側面に設けた振動部61と、振動板を兼ねる操作キーパネル41と、その中央に設けた伝達部411と、これら操作キーパネル41及びその伝達部411を介し前記振動部61の振動に応じて音を発生する振動板としても機能する表示パネル31とから構成している。   In the second embodiment, when the panel speaker 6 is folded in a mobile phone, the vibration part 61 provided on the inner surface of the operation key panel 41 of the operation part housing 2, the operation key panel 41 serving also as a vibration plate, and the center thereof And a display panel 31 that also functions as a diaphragm that generates sound according to the vibration of the vibration unit 61 via the operation key panel 41 and the transmission unit 411.

すなわち、図示のように、操作キーパネル41のヒンジ部5と反対側端部の内側面に、圧電素子による振動部61を貼り付けて、その振動板を兼ねた操作キーパネル41の長手方向の中央を横断するように、携帯電話の折り畳み状態において、表示部筐体1の表示パネル31の全周囲に当接する一様な連続凸条による伝達部411を形成している。そして、前述した実施形態1と同様に、操作部筐体2にも、携帯電話の折り畳み状態において、表示パネル31の全周囲に当接する一様な連続凸条による伝達部21を形成している。   That is, as shown in the drawing, a vibration part 61 made of a piezoelectric element is attached to the inner surface of the operation key panel 41 opposite to the hinge part 5, and the operation key panel 41 serving as the vibration plate is arranged in the longitudinal direction. In a folded state of the mobile phone, a transmission unit 411 is formed by uniform continuous ridges that are in contact with the entire periphery of the display panel 31 of the display unit housing 1 so as to cross the center. In the same manner as in the first embodiment, the operation unit housing 2 is also formed with a transmission unit 21 having a uniform continuous ridge that contacts the entire periphery of the display panel 31 in the folded state of the mobile phone. .

以上の構成により、携帯電話の折り畳み状態において、操作部筐体2の操作キーパネル41の内側面に設けた圧電素子による振動部61の振動は、振動板を兼ねる操作キーパネル41の中央の伝達部411に当接する、表示部筐体1の表示パネル31に伝達されて、その振動に応じて音が発生する。つまり、パネルスピーカ6として機能する。   With the above configuration, in the folded state of the mobile phone, the vibration of the vibration unit 61 by the piezoelectric element provided on the inner surface of the operation key panel 41 of the operation unit housing 2 is transmitted to the center of the operation key panel 41 that also serves as a diaphragm. The sound is generated according to the vibration transmitted to the display panel 31 of the display unit housing 1 that is in contact with the unit 411. That is, it functions as the panel speaker 6.

そして、パネルスピーカ6の振動は、前述した実施形態1と同様に、その振動板を兼ねた表示パネル31の全周囲に当接する伝達部21を介して操作部筐体2に伝達される。従って、パネルスピーカ6は、電話やメールの着信を知らせるバイブレータとしても使用される。
なお、振動部61の振動を操作キーパネル41に伝達させることによって、操作キーパネル41から音を発生させるようにしてもよい。
Then, the vibration of the panel speaker 6 is transmitted to the operation unit housing 2 through the transmission unit 21 that contacts the entire periphery of the display panel 31 that also serves as the diaphragm, as in the first embodiment. Accordingly, the panel speaker 6 is also used as a vibrator for notifying incoming calls or mails.
Note that sound may be generated from the operation key panel 41 by transmitting the vibration of the vibration unit 61 to the operation key panel 41.

以上、実施形態2の筐体のバイブレータ構造によっても、前述した実施形態1と同様の作用効果が得られる。   As mentioned above, the effect similar to Embodiment 1 mentioned above is acquired also by the vibrator structure of the housing | casing of Embodiment 2. FIG.
