The display unit 10 has a display surface 10a on the surface on the −Z-axis side. Images such as still images and moving images are displayed on the display surface 10a. For example, a liquid crystal display panel or an organic EL panel is used as the display unit 10. A touch panel mechanism (not shown) is provided on the display surface 10 a of the display unit 10.
　ベース部１１は、表示部１０を保持する。ベース部１１は、表示部１０の側部及び表示面１０ａの周縁部を囲うように形成されている。ベース部１１は、電子回路を収容するための第一筐体部分１０１となっている。 The base unit 11 holds the display unit 10. The base part 11 is formed so as to surround the side part of the display part 10 and the peripheral part of the display surface 10a. The base portion 11 is a first housing portion 101 for accommodating an electronic circuit.
　振動部１６は、固定部１６ａ、可動部１６ｂ及び駆動部を有する。固定部１６ａは、例えば円筒状に形成されており、可動部１６ｂ及び駆動部を収容する。固定部１６ａは、ボトムカバー１５の開口部内に配置されている。 The vibration part 16 has a fixed part 16a, a movable part 16b, and a drive part. The fixed part 16a is formed in a cylindrical shape, for example, and accommodates the movable part 16b and the drive part. The fixed portion 16 a is disposed in the opening of the bottom cover 15.
　可動部１６ｂは、Ｚ軸方向に移動可能に設けられている。駆動部は、可動部１６ｂに接続されており、この可動部１６ｂをＺ軸方向に移動させる。駆動部としては、例えばボイスコイルモーターなどが用いられている。駆動部の駆動動作は、制御回路によって行われる。 The movable part 16b is provided so as to be movable in the Z-axis direction. The drive unit is connected to the movable unit 16b and moves the movable unit 16b in the Z-axis direction. For example, a voice coil motor is used as the drive unit. The drive operation of the drive unit is performed by a control circuit.
　振動部１６は、駆動部が可動部１６ｂをＺ軸方向に往復移動させることにより、可動部１６ｂがＺ軸方向に振動する構成である。 The vibration unit 16 has a configuration in which the movable unit 16b vibrates in the Z-axis direction when the drive unit reciprocates the movable unit 16b in the Z-axis direction.
　接触検出部２２は、表示部１０の表示面１０ａの設置される面に対する側面それぞれに設置され、表示部１０の４辺を囲うように、Ｚ軸方向視で矩形の枠状に形成されている。接触検出部２２は、外部からの（例えばユーザの）接触の有無及び接触位置を検出する。 The contact detection unit 22 is installed on each of the side surfaces of the display unit 10 with respect to the surface on which the display surface 10a is installed, and is formed in a rectangular frame shape when viewed in the Z-axis direction so as to surround the four sides of the display unit 10. . The contact detection unit 22 detects the presence / absence of a contact from the outside (for example, a user) and the contact position.
　スピーカ２４は、外部に音声を出力する。 Speaker 24 outputs sound to the outside.
　図１及び図２に示すように、カバー部材２６は、電子機器１００の＋Ｚ軸側の端部を覆っている。カバー部材２６は、接触検出部２２を有している。 1 and 2, the cover member 26 covers the + Z-axis end of the electronic device 100. The cover member 26 has a contact detection unit 22.
　カバー部材２６及び接触検出部２２は、電子回路を収容するための第二筐体部分１０２となっている。また、この第二筐体部分１０２と、上記のベース部１１からなる第一筐体部分１０１とにより、電子機器１００の筐体が構成されている。 The cover member 26 and the contact detection unit 22 are a second housing portion 102 for accommodating an electronic circuit. In addition, the second housing portion 102 and the first housing portion 101 including the base portion 11 constitute a housing of the electronic device 100.
　カバー部材２６は、振動部１６の可動部１６ｂに接続されている。したがって、カバー部材２６は、可動部１６ｂと一体的にＺ軸方向に移動可能に設けられている。可動部１６ｂがＺ軸方向に振動することにより、この可動部１６ｂの振動がカバー部材２６に伝達され、カバー部材２６がＺ軸方向に振動するようになっている。 The cover member 26 is connected to the movable part 16b of the vibration part 16. Therefore, the cover member 26 is provided so as to be movable in the Z-axis direction integrally with the movable portion 16b. When the movable portion 16b vibrates in the Z-axis direction, the vibration of the movable portion 16b is transmitted to the cover member 26, and the cover member 26 vibrates in the Z-axis direction.
　例えば、可動部１６ｂが図１に示す状態から＋Ｚ軸方向に移動する場合には、図２に示すように、カバー部材２６及び接触検出部２２は可動部１６ｂの移動に伴って＋Ｚ軸方向へ移動する。したがって、第一筐体部分１０１と第二筐体部分１０２との間が広がることになり、第一筐体部分１０１と第二筐体部分１０２との間で相対的な移動が行われたことになる。 For example, when the movable part 16b moves in the + Z-axis direction from the state shown in FIG. 1, the cover member 26 and the contact detection part 22 move in the + Z-axis direction as the movable part 16b moves, as shown in FIG. Moving. Accordingly, the space between the first housing portion 101 and the second housing portion 102 is widened, and the relative movement between the first housing portion 101 and the second housing portion 102 has been performed. become.
　また、可動部１６ｂが図２に示す状態から－Ｚ軸方向に移動する場合には、カバー部材２６は可動部１６ｂの移動に伴って－Ｚ軸方向へ移動し、図１に示す状態に戻る。この場合にも、第一筐体部分１０１と第二筐体部分１０２との間で相対的な移動が行われたことになる。本実施形態の場合、可動部１６ｂをＺ軸方向に往復移動（振動）させることにより、カバー部材２６及び接触検出部２２が振動する。 When the movable portion 16b moves in the −Z-axis direction from the state shown in FIG. 2, the cover member 26 moves in the −Z-axis direction as the movable portion 16b moves, and returns to the state shown in FIG. . Also in this case, a relative movement has been performed between the first housing portion 101 and the second housing portion 102. In the case of this embodiment, the cover member 26 and the contact detection unit 22 vibrate by reciprocating (vibrating) the movable part 16b in the Z-axis direction.
　このように、電子機器１００は、電子回路を収容するための第一筐体部分１０１及び第二筐体部分１０２を有する筐体と、所定方向に振動して第一筐体部分１０１と第二筐体部分１０２とを相対的に移動させる振動部１６とを備える。そのため、第一筐体部分１０１及び第二筐体部分１０２のうち少なくとも一方を直接振動させることができる。これにより、振動を効率的に外部に伝達することが可能となる。 As described above, the electronic device 100 includes a housing having the first housing portion 101 and the second housing portion 102 for housing the electronic circuit, and the first housing portion 101 and the second housing that vibrate in a predetermined direction. The vibration part 16 which moves the housing | casing part 102 relatively is provided. Therefore, at least one of the first housing part 101 and the second housing part 102 can be directly vibrated. As a result, vibration can be efficiently transmitted to the outside.

The operation storage unit 131 stores reference data of movement of the electronic device 100 for executing each function. The acceleration data storage unit 132 stores acceleration data corresponding to each vibration data. The vibration data includes vibration amplitude and frequency of vibration. The acceleration data is data indicating the acceleration detected by the acceleration sensor 113 in each of the three axes when the vibration unit 16 generates vibration based on the corresponding vibration data. That is, the acceleration data storage unit 132 stores the acceleration associated with at least one of the amplitude and frequency information.

Based on the above, the movement of the apparatus main body is detected. Specifically, the motion detection unit 121 reads acceleration data corresponding to vibration data of vibration generated by the vibration unit 16 from the acceleration data storage unit 132. Then, the acceleration indicated by the acceleration data corresponding to the vibration data of the vibration generated by the read vibration unit 16 is subtracted (removed) from the acceleration detected by the acceleration sensor 113. As described above, the motion detection unit 121 generates motion data of the own device (device main body) based on the acceleration after subtraction.

　次に、図７及び図８を参照して、本実施形態による電子機器１００における動き検出処理について説明する。図７は、本実施形態による動き検出処理の動作を説明するための図である。 Next, with reference to FIGS. 7 and 8, the motion detection process in the electronic device 100 according to the present embodiment will be described. FIG. 7 is a diagram for explaining the operation of the motion detection process according to the present embodiment.
　以下、電子機器１００が音楽を再生している際に、ユーザが電子機器１００を直線上に動かすジェスチャーをした場合を例に説明する。電子機器１００は、音楽を音声出力部１１６から出力するとともに、音楽に応じた振動を振動部１６により発生している。 Hereinafter, a case where the user performs a gesture for moving the electronic device 100 on a straight line while the electronic device 100 is reproducing music will be described as an example. In the electronic device 100, music is output from the audio output unit 116, and vibration corresponding to the music is generated by the vibration unit 16.
　図７（ａ）は、この場合における電子機器（自装置、装置本体）１００の動きＡを示す。動きＡは、ユーザによるジェスチャー（直線運動）と、振動部１６による振動とが混合された動きである。動きＡにおいて、Ｚ軸方向の動きが振動による動きであり、Ｘ軸方向の動きがユーザによるジェスチャー（直線運動）である。電子機器１００の加速度センサ１１３は、動きＡに対応する加速度を検出し、検出した加速度を動き検出部１２１に出力する。また、振動制御部１２３は、振動部１６が発生する振動の振動データを動き検出部１２１に出力する。 FIG. 7A shows the movement A of the electronic device (self apparatus, apparatus main body) 100 in this case. The motion A is a motion in which a gesture by the user (linear motion) and vibration by the vibration unit 16 are mixed. In the movement A, the movement in the Z-axis direction is a movement by vibration, and the movement in the X-axis direction is a gesture (linear movement) by the user. The acceleration sensor 113 of the electronic device 100 detects the acceleration corresponding to the motion A, and outputs the detected acceleration to the motion detection unit 121. Further, the vibration control unit 123 outputs vibration data of vibrations generated by the vibration unit 16 to the motion detection unit 121.
　動き検出部１２１は、振動制御部１２３により入力された振動データに対応する加速度データを読み出す。この加速度データは、振動部１６の振動により発生する加速度のデータである。次に、動き検出部１２１は、読み出した加速度データの加速度を加速度センサ１１３が検出した加速度から差し引く。そして、動き検出部１２１は、差し引き後の加速度に基づいて電子機器１００の動きＢを検出する。 The motion detection unit 121 reads acceleration data corresponding to the vibration data input by the vibration control unit 123. This acceleration data is data of acceleration generated by the vibration of the vibration unit 16. Next, the motion detection unit 121 subtracts the acceleration of the read acceleration data from the acceleration detected by the acceleration sensor 113. Then, the motion detection unit 121 detects the motion B of the electronic device 100 based on the acceleration after subtraction.
　図７（ｂ）は、動き検出部１２１が検出した動きＢを示す。本図に示すように、動き検出部１２１は、実際の電子機器１００の動きＡから振動によるＺ軸方向の動きを除去した動きＢを検出する。実行制御部１２２は、動きＢに対応する機能を判定し、電子機器１００の各部を制御して機能を実行する。このように、電子機器１００は、振動を発生している場合は、その振動による動きを除去した動きＢを検出する。これにより、電子機器１００が振動している場合であっても、ユーザは意思通りのジェスチャー操作をすることができる。 FIG. 7B shows the motion B detected by the motion detection unit 121. As shown in the figure, the motion detection unit 121 detects a motion B obtained by removing the motion in the Z-axis direction due to vibration from the actual motion A of the electronic device 100. The execution control unit 122 determines a function corresponding to the motion B, and controls each unit of the electronic device 100 to execute the function. Thus, when the vibration is generated, the electronic device 100 detects the movement B from which the movement due to the vibration is removed. Thereby, even if the electronic device 100 is vibrating, the user can perform a gesture operation as intended.
　図８は、本実施形態による動き検出処理の手順を示すフローチャートである。
　以下に示す動作は、振動部１６が振動を発生しているときに行われる。 FIG. 8 is a flowchart showing the procedure of motion detection processing according to this embodiment.
The following operation is performed when the vibration unit 16 is generating vibration.
　まず、加速度センサ１１３が、加速度を検出する（ステップＳ１０１）。 First, the acceleration sensor 113 detects acceleration (step S101).
　そして、振動制御部１２３が、ステップＳ１０１において加速度センサ１１３が加速度を検出したときに振動部１６が発生した振動の振動データを動き検出部１２１に出力する（ステップＳ１０２）。 The vibration control unit 123 outputs vibration data of vibration generated by the vibration unit 16 to the motion detection unit 121 when the acceleration sensor 113 detects acceleration in step S101 (step S102).
　次に、動き検出部１２１が、接触検出部２２により接触が検出されているか否かを判定する（ステップＳ１０３）。接触検出部２２は、ユーザが電子機器１００を保持していると接触を検出する。すなわち、動き検出部１２１は、ユーザが電子機器１００を保持しているか否かを判定する。接触検出部２２が接触を検出していない場合（すなわち、ユーザが電子機器１００を保持していない場合）（ステップＳ１０３：Ｎｏ）、ステップＳ１０１へ戻る。 Next, the motion detection unit 121 determines whether or not contact is detected by the contact detection unit 22 (step S103). The contact detection unit 22 detects contact when the user is holding the electronic device 100. That is, the motion detection unit 121 determines whether or not the user is holding the electronic device 100. When the contact detection unit 22 does not detect contact (that is, when the user does not hold the electronic device 100) (step S103: No), the process returns to step S101.
　一方、動き検出部１２１は、接触検出部２２が接触を検出している場合（すなわち、ユーザが電子機器１００を保持している場合）（ステップＳ１０３：Ｙｅｓ）、ステップＳ１０２において取得された振動データに対応する加速度データを加速度データ記憶部１３２から読み出して取得する（ステップＳ１０４）。 On the other hand, when the contact detection unit 22 detects contact (that is, when the user holds the electronic device 100) (step S103: Yes), the motion detection unit 121 acquires the vibration data acquired in step S102. The acceleration data corresponding to is read out from the acceleration data storage unit 132 and acquired (step S104).
　次に、動き検出部１２１は、ステップＳ１０１において検出された加速度から、ステップＳ１０４において読み出した加速度データの加速度を減算する（ステップＳ１０５）。 Next, the motion detection unit 121 subtracts the acceleration of the acceleration data read in step S104 from the acceleration detected in step S101 (step S105).
　そして、動き検出部１２１は、減算後の加速度に基づいて電子機器１００の動きを検出する（ステップＳ１０６）。 Then, the motion detection unit 121 detects the motion of the electronic device 100 based on the acceleration after subtraction (step S106).
　続いて、実行制御部１２２が、電子機器１００の動きが機能を実行するための操作であるか否かを判定する（ステップＳ１０７）。具体的には、実行制御部１２２は、電子機器１００の動きのデータに対応する基準データ（操作）が操作記憶部１３１に記憶されているか否かを判定する。対応するデータとは、動きが描く軌道がほぼ同一（所定の範囲内）であるデータである。電子機器１００の動きが機能を実行するための操作でない場合（ステップＳ１０７：Ｎｏ）、処理を終了する。 Subsequently, the execution control unit 122 determines whether or not the movement of the electronic device 100 is an operation for executing a function (step S107). Specifically, the execution control unit 122 determines whether or not reference data (operation) corresponding to the movement data of the electronic device 100 is stored in the operation storage unit 131. The corresponding data is data in which the trajectories drawn by the movement are almost the same (within a predetermined range). If the movement of the electronic device 100 is not an operation for executing a function (step S107: No), the process is terminated.
　一方、電子機器１００の動きが機能を実行するための操作である場合（ステップＳ１０７：Ｙｅｓ）、実行制御部１２２は、この操作に対応する機能を実行する（ステップＳ１０８）。 On the other hand, when the movement of the electronic device 100 is an operation for executing a function (step S107: Yes), the execution control unit 122 executes a function corresponding to this operation (step S108).
　このように、本実施形態によれば、電子機器１００は、振動による電子機器１００の動きを、加速度センサ１１３の検出した電子機器１００の動きから除去する。これにより、電子機器１００が振動している場合であっても、ユーザは意思通りのジェスチャー操作をすることができる。すなわち、振動部１６が発生する振動による入力を防ぐことができる。 Thus, according to the present embodiment, the electronic device 100 removes the movement of the electronic device 100 due to vibration from the movement of the electronic device 100 detected by the acceleration sensor 113. Thereby, even if the electronic device 100 is vibrating, the user can perform a gesture operation as intended. That is, it is possible to prevent an input due to vibration generated by the vibration unit 16.

　また、上記プログラムは、このプログラムを記憶装置等に格納したコンピュータシステムから、伝送媒体を介して、あるいは、伝送媒体中の伝送波により他のコンピュータシステムに伝送されてもよい。ここで、プログラムを伝送する「伝送媒体」は、インターネット等のネットワーク（通信網）や電話回線等の通信回線（通信線）のように情報を伝送する機能を有する媒体のことをいう。 The program may be transmitted from a computer system storing the program in a storage device or the like to another computer system via a transmission medium or by a transmission wave in the transmission medium. Here, the “transmission medium” for transmitting the program refers to a medium having a function of transmitting information, such as a network (communication network) such as the Internet or a communication line (communication line) such as a telephone line.
