Description

本発明は、着信時に振動する携帯電話機や所定の時期に振動を付与するゲーム用コントローラ等の振動機器及びその振動機器に搭載される振動モータに関する。   The present invention relates to a vibration device such as a mobile phone that vibrates when an incoming call is received, a game controller that applies vibration at a predetermined time, and a vibration motor mounted on the vibration device.

特許文献１には、振動機器の筐体内に搭載される振動モータが開示されている。かかる振動モータは給電ランドを筐体内に配置してある端子に接触させるようにしてあるが、給電ランドの先端は、振動モータ本体の軸線方向（長手方向）端部からモータ本体から離れる方向に延出し且つモータ本体の径方向（厚み方向）内で基板の端子に接触する構成になっている。   Patent Document 1 discloses a vibration motor mounted in a casing of a vibration device. In such a vibration motor, the power supply land is brought into contact with a terminal arranged in the housing, but the tip of the power supply land extends from the axial direction (longitudinal direction) end of the vibration motor body in a direction away from the motor body. It is configured to be in contact with the terminal of the substrate in the radial direction (thickness direction) of the motor body.

また、特許文献１の図９には、従来技術として振動モータ本体の上部側面に給電ランドを設けることが開示されている。   Further, FIG. 9 of Patent Document 1 discloses that a power feeding land is provided on the upper side surface of the vibration motor main body as a conventional technique.

しかし、特許文献１の技術では、給電ランドが振動モータ本体の軸線方向端部から、モータから離れる方向に延出する構成であるから給電ランドを含めた振動モータの全長が長くなるという問題がある。   However, the technique of Patent Document 1 has a problem that the entire length of the vibration motor including the power feeding land becomes longer because the power feeding land extends from the axial end of the vibration motor body in the direction away from the motor. .

また、給電ランドに接触する端子の基板を振動モータの軸線方向に直列に配置する構成である為、振動モータと基板とが振動機器の筐体内で占める面積が大きくなり振動モータを搭載する振動機器の小型化に限界があった。   In addition, since the substrate of the terminal that contacts the power feeding land is arranged in series in the axial direction of the vibration motor, the area occupied by the vibration motor and the substrate in the housing of the vibration device increases, and the vibration device is equipped with the vibration motor. There was a limit to miniaturization of.

更に、特許文献１の振動モータは、振動機器に組み込まれたときに筐体の底面（底壁）と天面（上壁）とで挟まれて保持されている為、筐体及び振動モータの寸法に精度が要求されると共に振動モータの組付けの自由度が制限されるという問題があった。   Furthermore, since the vibration motor of Patent Document 1 is sandwiched and held between the bottom surface (bottom wall) and the top surface (top wall) of the housing when incorporated in a vibration device, the housing and vibration motor There is a problem that accuracy is required for the dimensions and the degree of freedom in assembling the vibration motor is limited.

一方、特許文献１の図９に記載の従来技術では、給電ランドを本体上側面に設けているので、振動モータの厚み（径方向の寸法）が厚くなると共に振動モータを搭載する振動機器の厚みが大きくなる為、振動機器の小型化に限界があった。   On the other hand, in the prior art described in FIG. 9 of Patent Document 1, since the feeding land is provided on the upper side surface of the main body, the thickness of the vibration motor (dimension in the radial direction) increases and the thickness of the vibration device on which the vibration motor is mounted. Therefore, there was a limit to downsizing vibration devices.

そこで、本発明は、振動モータの軸線方向の寸法（長さ）及び厚みを小さくできると共に振動モータを搭載する振動機器の小型化を図り、且つ振動機器の筐体寸法の制限を受け難い振動モータ及び振動機器の提供を目的とする。   Accordingly, the present invention can reduce the size (length) and thickness of the vibration motor in the axial direction, reduce the size of the vibration device on which the vibration motor is mounted, and are not easily restricted by the casing size of the vibration device. And to provide vibration equipment.

It extends to the side of the motor body along the side surface, and the tip of the power feeding land is located within the thickness dimension of the motor body in a state where the terminal in the housing is pressed from above.

尚、モータ本体の厚みは、筐体内に配置されたときの底面（底壁）と天面（上壁）との間におけるモータの本体の寸法をいう。   The thickness of the motor main body refers to the dimension of the motor main body between the bottom surface (bottom wall) and the top surface (top wall) when arranged in the housing.

請求項２に記載の発明は、請求項１に記載の発明において、一対の給電ランドは、一方の給電ランドと他方の給電ランドとでモータ本体を挟む位置にあることを特徴とする。   According to a second aspect of the present invention, in the first aspect of the present invention, the pair of power feeding lands are located between the one power feeding land and the other power feeding land.

請求項３に記載の発明は、請求項１又は２に記載の発明において、モータ本体には少なくともモータの底部と側部とに弾性被覆体が装着してあり、弾性被覆体は筐体内の基板が当接して基板を受ける基板受け部を備え、基板受け部はモータ本体を挟む両側部に設けてあり、振動モータを筐体内に装着したときに基板が基板受け部に上方から圧接することを特徴とする。   According to a third aspect of the present invention, in the first or second aspect of the present invention, the motor body is provided with an elastic covering at least on the bottom and the side of the motor, and the elastic covering is a substrate in the housing. The board receiving part is provided on both sides sandwiching the motor body so that the board is pressed against the board receiving part from above when the vibration motor is mounted in the housing. Features.

請求項４に記載の発明は、請求項３に記載の撮像装置において、弾性被覆体の本体部は軟質樹脂製であり、基板受け部は硬質樹脂製であり且つ本体部と別体に形成してあり、本体部に嵌合固定してあることを特徴とする。   According to a fourth aspect of the present invention, in the imaging device according to the third aspect, the main body portion of the elastic covering is made of a soft resin, the substrate receiving portion is made of a hard resin, and is formed separately from the main body portion. And is fitted and fixed to the main body.

請求項５に記載の発明は、請求項１〜４のいずれか一項に記載の撮像装置において、請求項１〜４のいずれか一項に記載の振動モータを筐体内に配置したことを特徴とする。   According to a fifth aspect of the present invention, in the imaging apparatus according to any one of the first to fourth aspects, the vibration motor according to any one of the first to fourth aspects is disposed in a housing. And

請求項１に記載の発明によれば、給電ランドはモータ本体の側面に沿って配置してあるから、モータ本体の軸線方向に突設しないので、振動モータ全体の長さを小さくできる。また、振動モータを筐体内に収めた状態において、給電ランドの先端はモータ本体の側部において厚み寸法内に位置するので振動モータの厚み方向の寸法も小さくできる。   According to the first aspect of the present invention, since the power feeding land is arranged along the side surface of the motor main body, it does not project in the axial direction of the motor main body, so that the overall length of the vibration motor can be reduced. Further, in the state where the vibration motor is housed in the casing, the tip of the power feeding land is located within the thickness dimension at the side portion of the motor body, so that the dimension in the thickness direction of the vibration motor can be reduced.

給電ランドの先端に接触する端子を有する基板をモータの軸線方向にモータと直列に配置しなくて済むので、振動モータ及び筐体に設ける基板が占めるスペースを小さくできる。   Since it is not necessary to arrange a substrate having a terminal in contact with the tip of the power feeding land in series with the motor in the axial direction of the motor, the space occupied by the substrate provided in the vibration motor and the housing can be reduced.

振動モータを筐体内に搭載した状態では、基板の端子が給電ランドに上方から押圧接触することにより、モータ本体を筐体底面に押付けてモータ本体を筐体内に保持することができる。したがって、筐体の底面と天面との位置の制約を受けないので、筐体や振動モータの寸法精度が要求されず且つ振動モータの組付けの自由度が高い。   In a state where the vibration motor is mounted in the casing, the terminal of the board is pressed and contacted with the power feeding land from above, whereby the motor main body can be pressed against the bottom surface of the casing and the motor main body can be held in the casing. Therefore, since there is no restriction on the position of the bottom surface and the top surface of the housing, the dimensional accuracy of the housing and the vibration motor is not required, and the degree of freedom of assembly of the vibration motor is high.

請求項２に記載の発明によれば、請求項１に記載の作用効果を得ることができると共に、一対の給電ランドはモータを両側から挟む位置にあるから、振動モータを筐体内に配置したときに基板の端子で給電ランドに押圧することにより、モータ本体をその両側から押えることができ、振動モータの固定強度が高く安定である。   According to the second aspect of the present invention, the function and effect of the first aspect can be obtained, and the pair of power feeding lands are positioned to sandwich the motor from both sides. Therefore, when the vibration motor is disposed in the housing The motor body can be pressed from both sides by pressing against the power feeding land with the terminal of the board, and the fixing strength of the vibration motor is high and stable.

Each power feeding land 11 is made of an elastic metal, and is formed by bending a base end portion 11b. In a natural state (a state where no load is applied), as shown in FIG. 1, a tip (contact end) 11a is a motor. It is located above the main body 9 (outward in the radial direction from the motor main body 9).

給電ランド１１の先端１１ａは、上方を凸にして湾曲してあると共に延出方向にスリット１５が形成されており、筐体３１に設けた基板３７の端子３９（図３及び図４参照）との接触を安定にしている。   The front end 11a of the power feeding land 11 is curved with a convex upward, and a slit 15 is formed in the extending direction.

弾性被覆体１３は、モータ本体９の上側面を除いてモータ本体９に被着してあり、平面視略矩形をなしている。弾性被覆体１３は、本体部１９と基板受け部２１とから構成されており、本体部１９には、給電ランド１１の先端１１ａの位置を規制する規制部１７が設けてある。この規制部１７は、モータ本体９の左右両側で、給電ランド１１の先端部１１ａが規制部１７よりも下に移動するのを規制している。   The elastic covering 13 is attached to the motor main body 9 except for the upper side surface of the motor main body 9, and has a substantially rectangular shape in plan view. The elastic covering 13 includes a main body 19 and a substrate receiving portion 21, and the main body 19 is provided with a restriction portion 17 that restricts the position of the tip 11 a of the power feeding land 11. The restricting portion 17 restricts the front end portion 11 a of the power feeding land 11 from moving below the restricting portion 17 on both the left and right sides of the motor body 9.

弾性被覆体１３の本体部１９は、軟質樹脂、例えば、シリコンゴムでできており、基板受け部２１は硬質樹脂、例えば、ナイロン樹脂である。   The main body portion 19 of the elastic covering 13 is made of a soft resin, for example, silicon rubber, and the substrate receiving portion 21 is a hard resin, for example, a nylon resin.

弾性被覆体１３の本体部１９には給電ランド１１の基端部側に段状の凹部２３が形成してあり、基板受け部２１には凹部２３に嵌合する段状の凸部２５が形成してあり、基板受け部２１を嵌合により本体部１９に取り付けるようになっている。

The board receiving portion 21 is attached to the main body portion 19 by fitting.
The power feeding land 11 is inserted through the board receiving portion 21.

次に、携帯電話機３について説明する。携帯電話機３には、振動モータ１の収納部３０が設けてあり、筐体３１の底壁３３と上壁３５の間には、基板３７が配置されている。基板３７は図４に示すように、平面視略コ字形状を成しており、振動モータ１のモータ本体９に対応する領域が空間になっており、振動モータ１を囲む位置に配置されている。基板３７において、給電ランド１１の先端１１ａに対応する位置には、給電ランド１１に押圧接触する端子３７が配置されている。尚、振動モータ１には、筐体３１に搭載する際に弾性被覆体１３を装着して収納部３０内に保持する保持部材３２が設けられている。   Next, the mobile phone 3 will be described. The cellular phone 3 is provided with a housing 30 for the vibration motor 1, and a substrate 37 is disposed between the bottom wall 33 and the top wall 35 of the housing 31. As shown in FIG. 4, the substrate 37 is substantially U-shaped in plan view, and a region corresponding to the motor body 9 of the vibration motor 1 is a space, and is disposed at a position surrounding the vibration motor 1. Yes. On the substrate 37, a terminal 37 that is in press contact with the power feeding land 11 is disposed at a position corresponding to the tip 11 a of the power feeding land 11. Note that the vibration motor 1 is provided with a holding member 32 that is attached to the housing 31 and is held in the storage portion 30 when mounted on the housing 31.

振動モータ１が携帯電話機３の筐体３１に収納された状態において、給電ランド１１は先端１１ａがその付勢力に抗して基板３７の端子３９の押し下げられて、給電ランド１１の先端１１ａと端子３９とが押圧接触する。同時に、基板３７は弾性被覆体１３の基板受け部２１に当接して、位置決めされる。   In a state where the vibration motor 1 is housed in the housing 31 of the mobile phone 3, the tip 11 a of the power feeding land 11 is pushed down against the urging force of the terminal 39 of the substrate 37, and the tip 11 a of the power feeding land 11 and the terminal 39 is in press contact. At the same time, the substrate 37 comes into contact with the substrate receiving portion 21 of the elastic covering 13 and is positioned.

次に、第１実施の形態にかかる振動モータ１及び携帯電話機３の作用及び効果について説明する。携帯電話機３への振動モータ１の搭載は、振動モータ１に保持部材３２を装着して、筐体３１における底壁３３の所定位置に配置した後、振動モータ１を取り囲むように基板３７を配置して上壁（上ケース）３５を閉じる。これにより、振動モータ１の給電ランド１１の先端１１ａが基板３７の端子に押圧接触する。   Next, operations and effects of the vibration motor 1 and the mobile phone 3 according to the first embodiment will be described. For mounting the vibration motor 1 on the cellular phone 3, the holding member 32 is mounted on the vibration motor 1 and disposed at a predetermined position on the bottom wall 33 of the housing 31, and then the substrate 37 is disposed so as to surround the vibration motor 1. Then, the upper wall (upper case) 35 is closed. As a result, the tip 11 a of the power feeding land 11 of the vibration motor 1 is in press contact with the terminal of the substrate 37.

本実施の形態によれば、給電ランド１１はモータ本体９の側面に沿って軸線方向に配置してあるから、給電ランド１１はモータ本体９の長さ方向（軸線方向）に突設しないので、振動モータ１全体の長さを小さくできる。   According to the present embodiment, since the power feeding land 11 is arranged in the axial direction along the side surface of the motor main body 9, the power feeding land 11 does not project in the length direction (axial direction) of the motor main body 9. The overall length of the vibration motor 1 can be reduced.

振動モータ１を携帯電話機３の筐体３１内に収めた状態において、給電ランド１１はモータ本体９の側部においてモータ本体９の厚み寸法（径方向寸法）内に位置するので筐体３１の厚みを小さくできる。   In a state where the vibration motor 1 is housed in the casing 31 of the mobile phone 3, the power feeding land 11 is positioned within the thickness dimension (diameter dimension) of the motor body 9 at the side of the motor body 9. Can be reduced.

基板３７は、モータ本体９を取り囲むようにして振動モータ１の側部に端子３９が位置するように配置しているので、基板３７と振動モータ１とが一方向に直列にならず、基板３７と振動モータ１との占有スペースを小さくできる。したがって、携帯電話機３の小型化を図ることができる。   Since the substrate 37 is disposed so as to surround the motor main body 9 so that the terminals 39 are positioned on the side portions of the vibration motor 1, the substrate 37 and the vibration motor 1 are not serially connected in one direction. And the space occupied by the vibration motor 1 can be reduced. Therefore, the mobile phone 3 can be downsized.

給電ランド１１、１１は、弾性金属を折り曲げて形成しているので、作用する付勢力を強くでき、給電ランド１１、１１と基板３７の端子３９との接触圧を強くして接触を確実に行わせることができる。   Since the power feeding lands 11 and 11 are formed by bending an elastic metal, the applied urging force can be increased, and the contact pressure between the power feeding lands 11 and 11 and the terminal 39 of the substrate 37 is increased to ensure contact. Can be made.

一対の給電ランド１１、１１はモータ本体９を両側から挟む位置にあり、振動モータ１を筐体３１内に配置したときに基板３７の端子３９で給電ランド１１に押圧することにより、モータ本体９をその両側から付勢しているので、筐体３１内における振動モータ１の固定強度を高めることができる。   The pair of power feeding lands 11, 11 are positioned so as to sandwich the motor main body 9 from both sides, and when the vibration motor 1 is disposed in the housing 31, the motor main body 9 is pressed against the power feeding land 11 by the terminal 39 of the substrate 37. , And the fixing strength of the vibration motor 1 in the housing 31 can be increased.

更に、被弾性被覆体１３の基板受け部２１に基板３７が当接して振動モータ１を押えているので、振動モータ１を筐体３１内に強固に保持することができる。   Furthermore, since the substrate 37 is in contact with the substrate receiving portion 21 of the elastic covering body 13 and presses the vibration motor 1, the vibration motor 1 can be firmly held in the housing 31.

被弾性被覆体１３の基板受け部２１に基板３７が当接しているので、給電ランド１１、１１と端子３９との接触圧を略一定にすることができる。また、携帯電話機３の落下等による衝撃があっても、基板３７を振動モータ１の弾性被覆体１３で弾性力をもって支持するので、基板３７の損傷を防止できる。   Since the substrate 37 is in contact with the substrate receiving portion 21 of the elastic cover 13, the contact pressure between the power feeding lands 11 and 11 and the terminal 39 can be made substantially constant. Even if there is an impact due to dropping of the mobile phone 3 or the like, the substrate 37 is supported by the elastic covering body 13 of the vibration motor 1 with an elastic force, so that the substrate 37 can be prevented from being damaged.

基板受け部２１は、弾性被覆体１３の本体部１９に嵌合しているので取付けが容易にできる。   Since the board | substrate receiving part 21 is fitted in the main-body part 19 of the elastic coating | covering body 13, attachment can be performed easily.
