Abstract

PROBLEM TO BE SOLVED: To provide a vibration detector capable of removing noise due to an air-borne sound.SOLUTION: In the vibration detector for detecting vibration by touching an object, switch means SW1, SW2 for actuating a vibration detection element 2 when touching the object, and stopping operation when separated from the object are provided. When the vibration detector is separated from the object, operation of the vibration detection element is stopped by the switch means, and thereby an air-borne sound is never picked up, and when the vibration detector touches the object, detection operation is performed by actuating the vibration detection element by the switch means. Consequently, noise due to air-borne sound can be removed.

Description

本発明は、人体や物などの対象物に接触させて振動を検出する振動検出装置に関する。   The present invention relates to a vibration detection apparatus that detects vibration by contacting an object such as a human body or an object.

近年、人体などから直接音声を収音する接触型マイクロホンとして、肉伝導マイクロホンや骨伝導マイクロホンが開発されている。   In recent years, meat-conduction microphones and bone-conduction microphones have been developed as contact-type microphones that directly collect sound from the human body.

肉伝導マイクロホンは、人体の軟部組織、例えば皮膚や筋肉、脂肪などの弾性のある組織を媒体とする音の伝達を収音するものであり、例えば耳の後下部にある乳様突起という部位に接触させてささやき声のような極小さな体導音を拾うものが提案されている（非特許文献１参照）。一方、骨伝導マイクロホンは、人体の骨を媒体とする音の伝達を利用するものであり、額部分などの比較的皮膚の薄いところにセンサを取り付けて音声等を収音する。   Meat conduction microphones collect sound transmission through soft tissues of the human body, such as elastic tissues such as skin, muscles, and fats. There has been proposed one that picks up a very small body-conducting sound such as a whispering voice (see Non-Patent Document 1). On the other hand, the bone conduction microphone utilizes sound transmission using the bones of the human body as a medium, and attaches a sensor to a relatively thin part of the skin such as the forehead part to collect sound.

ここに体導音とは、音源によって引き起こされた振動が肉を伝搬する肉導音や骨を伝搬する骨導音をいう。これに対し、空気を伝搬する音は空気伝搬音あるいは気導音という。肉伝導マイクロホンは電子聴診器などに使われ、軟部組織を介して伝わる体導音を直接サンプリングできるので、通常の発声音量より小さいものでも感度良く検出できるという利点がある。   Here, the body-conducted sound refers to a meat-conducted sound in which vibration caused by a sound source propagates through meat or a bone-conducted sound that propagates through bone. On the other hand, the sound that propagates in air is called air propagation sound or air conduction sound. The meat conduction microphone is used for an electronic stethoscope and can directly sample the body conduction sound transmitted through the soft tissue, so that it has an advantage that even a sound volume smaller than a normal utterance volume can be detected with high sensitivity.

しかしながら、体導音を検出する肉伝導マイクロホンや骨伝導マイクロホンなどの従来の振動検出装置は、その構造上、非接触時（非使用時）の空気伝搬音が大きなノイズとなってしまうため、体導音に対する空気伝搬音の感度を低く抑えることが課題となっている。   However, conventional vibration detection devices such as a body conduction microphone and a bone conduction microphone that detect body conduction sound, due to the structure, air propagation sound when not in contact (when not in use) becomes a large noise. It has been a challenge to reduce the sensitivity of air-borne sound to guided sound.

すなわち、体導音の感度を高くすると、振動検出装置を人体から離している状態で空気伝搬音を拾ってしまうため、ノイズを小さくするためには感度を下げざるを得ない。   That is, if the sensitivity of the body-conducted sound is increased, air-borne sound is picked up while the vibration detection device is separated from the human body, so the sensitivity must be lowered to reduce the noise.

本発明は上記のことに鑑み提案されたもので、その目的とするところは、空気伝搬音に起因するノイズを除去できる振動検出装置を提供することにある。   The present invention has been proposed in view of the above, and an object of the present invention is to provide a vibration detection apparatus capable of removing noise caused by air-borne sound.

And switch means SW1 and SW2 for stopping the operation when separated from the object.

請求項２に係る発明は、請求項１に記載の振動検出装置において、前記スイッチ手段は、前記振動検出素子２を収容し、一端側を対象物に接触させた時の圧力により弾性変形する接触部材３と、この接触部材３の他端側に設けられ、前記接触部材３の弾性変形によりオンするスイッチＳＷ１とを備えることを特徴とする。   According to a second aspect of the present invention, in the vibration detecting device according to the first aspect, the switch means accommodates the vibration detecting element 2 and is elastically deformed by pressure when one end side is brought into contact with an object. A member 3 and a switch SW1 provided on the other end side of the contact member 3 and turned on by elastic deformation of the contact member 3 are provided.

請求項３に係る発明は、請求項２に記載の振動検出装置において、前記スイッチＳＷ１は、基板７上に設けられた複数の端子と、この基板７の前記複数の端子上に対向する前記接触部材３の他端側に設けられ、前記接触部材３の一端側を対象物に接触させた時の圧力による弾性変形で押し下げられて前記複数の端子間を短絡する導電性部材５とを備えることを特徴とする。   According to a third aspect of the present invention, in the vibration detecting device according to the second aspect, the switch SW1 includes a plurality of terminals provided on the substrate 7 and the contact facing the plurality of terminals of the substrate 7. A conductive member 5 provided on the other end side of the member 3 and pressed down by elastic deformation caused by pressure when the one end side of the contact member 3 is brought into contact with an object to short-circuit the plurality of terminals. It is characterized by.

請求項４に係る発明は、請求項１に記載の振動検出装置において、前記スイッチ手段は、前記振動検出素子２における対象物との接触圧力を検知する感圧スイッチＳＷ２であることを特徴とする。   According to a fourth aspect of the present invention, in the vibration detection device according to the first aspect, the switch means is a pressure-sensitive switch SW2 that detects a contact pressure between the vibration detection element 2 and an object. .

請求項１に係る本発明の振動検出装置によれば、振動検出装置を対象物から離している状態ではスイッチ手段により振動検出素子の動作が停止されるため、空気伝搬音を拾うことはない。一方、振動検出装置を対象物に接触させると、スイッチ手段により振動検出素子を作動させて検出動作を行う。従って、空気伝搬音に起因するノイズを除去できる。   According to the vibration detection apparatus of the present invention according to claim 1, since the operation of the vibration detection element is stopped by the switch means in a state where the vibration detection apparatus is separated from the object, the air propagation sound is not picked up. On the other hand, when the vibration detection device is brought into contact with the object, the detection operation is performed by operating the vibration detection element by the switch means. Therefore, it is possible to remove noise caused by air-borne sound.

以下、本発明の実施形態を図面に基づいて説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１は本発明の実施の形態に係る振動検出装置を示しており、（ａ）図は平面図、（ｂ）図は（ａ）図のＡ−Ａ’線矢示断面図である。図１において、１は振動検出素子２を収容したケースで、このケース１は上部ケース１ａと下部ケース１ｂとを側面の嵌合部１ｃで嵌合させることにより一体化されている。上部ケース１ａの上面には円形の開口１ｄが形成されており、この上部ケース１ａの内側の上記開口１ｄの周りには円筒状の取付部１ｅが形成されている。   1A and 1B show a vibration detection apparatus according to an embodiment of the present invention. FIG. 1A is a plan view, and FIG. 1B is a cross-sectional view taken along the line A-A ′ of FIG. In FIG. 1, reference numeral 1 denotes a case in which a vibration detection element 2 is accommodated. The case 1 is integrated by fitting an upper case 1a and a lower case 1b with side fitting portions 1c. A circular opening 1d is formed on the upper surface of the upper case 1a, and a cylindrical mounting portion 1e is formed around the opening 1d inside the upper case 1a.

この取付部１ｅには、例えばエラストマなどの弾性変形する接触部材３が装着される。この接触部材３は、接触部３ａ、装着部３ｂ、変形部３ｃを有し、側面が外壁と内壁の二重構造の有底円筒形状である。上記接触部３ａは、上部ケース１ａの開口１ｄ内に、この上部ケース１ａの上面から突出して配置されている。上記装着部３ｂは上記取付部１ｅにおける円筒の外周に沿って装着される。上記変形部３ｃは、接触部材３の下側に位置しており、接触部３ａを皮膚などに接触させたときに弾性変形して上記有底円筒の内側の部分を下降させ、皮膚から離したときに変形が戻って上昇させるようになっている。   A contact member 3 that is elastically deformed, such as an elastomer, is attached to the attachment portion 1e. The contact member 3 includes a contact portion 3a, a mounting portion 3b, and a deformable portion 3c, and has a bottomed cylindrical shape having a double structure with a side wall and an outer wall. The contact portion 3a is disposed in the opening 1d of the upper case 1a so as to protrude from the upper surface of the upper case 1a. The mounting portion 3b is mounted along the outer periphery of the cylinder in the mounting portion 1e. The deforming portion 3c is located below the contact member 3, and is elastically deformed when the contact portion 3a is brought into contact with the skin or the like to lower the inner portion of the bottomed cylinder and away from the skin. Sometimes the deformation comes back and rises.

上記接触部材３内には振動検出素子２が収容部材４に収容されて設置されている。この振動検出素子２には、例えば圧電セラミック素子やエレクトレット膜を用いて振動を電気信号に変換するものを用いる。上記収容部材４は、上部に振動検出素子２の上面に空間を形成するためのスペーサ部４ａと、振動検出素子２を収容するための収容部４ｂとを備えている。そして、収容部材４の底面には、スイッチＳＷ１の可動接点として働く導電性部材５が固着されている。上記振動検出素子２の配線用のコード６は、上記接触部材３と上記円筒状の取付部１ｅの対応する側面に形成されたスリット状の開孔３ｄ、１ｆを介してケース１内に導かれている。   In the contact member 3, the vibration detection element 2 is housed and installed in the housing member 4. As the vibration detection element 2, for example, a piezoelectric ceramic element or an electret film that converts vibration into an electric signal is used. The housing member 4 includes a spacer portion 4 a for forming a space on the upper surface of the vibration detection element 2 and an accommodation portion 4 b for housing the vibration detection element 2 in the upper part. A conductive member 5 that works as a movable contact of the switch SW1 is fixed to the bottom surface of the housing member 4. The wiring cord 6 of the vibration detecting element 2 is guided into the case 1 through slit-shaped openings 3d and 1f formed on corresponding side surfaces of the contact member 3 and the cylindrical mounting portion 1e. ing.

一方、下部ケース１ｂ内には、台座としての突起部１ｇ、１ｈ上に基板７が載置されている。この基板７の上記導電性部材５下に対応する表面には、導電性部材５と離隔して上記スイッチＳＷ１の固定接点として働く複数（例えば一対）の端子、あるいは一つの端子を二つに分割した分割端子が設けられている。上記接触部材３、導電性部材５および複数の端子により、皮膚への接触部３ａに連結された押下式のスイッチＳＷ１が構成される。   On the other hand, in the lower case 1b, the substrate 7 is placed on the protrusions 1g and 1h as pedestals. A plurality of (for example, a pair of) terminals that act as fixed contacts of the switch SW1 are separated from the conductive member 5 on the surface corresponding to the bottom of the conductive member 5 of the substrate 7, or one terminal is divided into two. Divided terminals are provided. The contact member 3, the conductive member 5, and a plurality of terminals constitute a push-down switch SW1 connected to the skin contact portion 3a.

上記一対の端子のうち一方は、基板７上に形成された配線パターンを介して、上記ケース１の側面に形成されたコード引出部１ｉから外部に引き出されるコード８の一端に接続される。また、他方は、基板７上に形成された配線パターンなどを介して上記振動検出素子２の配線用の一方のコード６に電気的に接続される。   One of the pair of terminals is connected to one end of a cord 8 drawn out from a cord lead portion 1 i formed on the side surface of the case 1 through a wiring pattern formed on the substrate 7. The other is electrically connected to one cord 6 for wiring of the vibration detecting element 2 through a wiring pattern formed on the substrate 7.

図示しないが、上記振動検出素子２の配線用の他方のコードは、上記コード引出部１ｉから外部に引き出されるコード８の一端に電気的に接続される。   Although not shown, the other cord for wiring of the vibration detecting element 2 is electrically connected to one end of a cord 8 drawn out from the cord lead-out portion 1i.

上記のような構成において、図２に示すように上部ケース１ａを振動検出の対象物、例えば人体の皮膚９に接触させると、上部ケース１ａの上面から突出した接触部材３の接触部３ａが加圧される。この接触部材３はエラストマなどの弾性変形する材料で形成されているので、変形部３ｃが弾性変形して導電性部材５が下方に下がりスイッチＳＷ１の固定接点として働く一対の端子を短絡する。   In the configuration as described above, as shown in FIG. 2, when the upper case 1a is brought into contact with an object of vibration detection, for example, the skin 9 of the human body, the contact portion 3a of the contact member 3 protruding from the upper surface of the upper case 1a is added. Pressed. Since the contact member 3 is formed of an elastically deformable material such as an elastomer, the deformable portion 3c is elastically deformed, and the conductive member 5 is lowered to short-circuit a pair of terminals serving as fixed contacts of the switch SW1.

これによって、振動検出素子２が動作状態となり、コード６、８を介して検出信号が外部に出力される。一方、ケース１を皮膚９から離すと、変形部３ｃの変形が戻り、導電性部材５が上方に移動して図１（ｂ）に示した状態となり、スイッチＳＷ１の固定接点として働く一対の端子が開放される。この状態では、振動検出素子２が非動作状態となり、検出動作は行われないので、空気伝搬音をノイズとして拾うことはない。   As a result, the vibration detecting element 2 enters an operating state, and a detection signal is output to the outside via the cords 6 and 8. On the other hand, when the case 1 is separated from the skin 9, the deformation of the deformable portion 3c is restored, and the conductive member 5 moves upward to be in the state shown in FIG. 1B, and a pair of terminals functioning as a fixed contact of the switch SW1. Is released. In this state, the vibration detection element 2 is in a non-operating state, and no detection operation is performed, so that air-borne sound is not picked up as noise.

上述したように、ケース１の接触部材３を皮膚９から離している状態ではスイッチＳＷ１により振動検出素子２の動作が停止されているため、空気伝搬音を拾うことはない。一方、接触部材３を皮膚９に接触させると、スイッチＳＷ１により振動検出素子２が作動されて検出動作を行う。従って、体導音の感度を高くしても空気伝搬音に起因するノイズを除去できる。   As described above, since the operation of the vibration detection element 2 is stopped by the switch SW1 when the contact member 3 of the case 1 is separated from the skin 9, the air propagation sound is not picked up. On the other hand, when the contact member 3 is brought into contact with the skin 9, the vibration detection element 2 is activated by the switch SW1 to perform a detection operation. Therefore, even if the sensitivity of the body-conducted sound is increased, noise caused by the air-borne sound can be removed.

また、スイッチＳＷ１に弾性変形する接触部材３を用いることで、対象物である皮膚９に接触させた時の圧力により振動検出素子２を作動させ、皮膚９から離したときは変形が戻るのを利用して振動検出素子２の動作を停止させることができるので、使用者がスイッチＳＷ１の存在を意識することなく振動検出素子２のオン／オフ操作ができる。   Further, by using the contact member 3 that is elastically deformed for the switch SW1, the vibration detecting element 2 is operated by the pressure when it is brought into contact with the skin 9 as the object, and the deformation is returned when it is separated from the skin 9. Since the operation of the vibration detection element 2 can be stopped by using it, the vibration detection element 2 can be turned on / off without the user being aware of the presence of the switch SW1.

しかも、スイッチＳＷ１を基板７上に形成した一対の端子と、導電性部材５とで構成できるので低コスト化ができる。   In addition, since the switch SW1 can be composed of the pair of terminals formed on the substrate 7 and the conductive member 5, the cost can be reduced.

図３は、本発明の他の実施の形態に係る振動検出装置を示すもので、（ａ）図は図１（ｂ）に対応する断面図、（ｂ）図は感圧スイッチの構成例を示す断面図である。上述した実施の形態では導電性部材５を基板７上の一対の端子または分割端子に接触させて短絡させる構造のスイッチＳＷ１を例に挙げたが、本実施の形態では感圧スイッチＳＷ２を用いている。   3A and 3B show a vibration detection apparatus according to another embodiment of the present invention. FIG. 3A is a cross-sectional view corresponding to FIG. 1B, and FIG. 3B is a configuration example of a pressure-sensitive switch. It is sectional drawing shown. In the above-described embodiment, the switch SW1 having a structure in which the conductive member 5 is brought into contact with the pair of terminals or the divided terminals on the substrate 7 and short-circuited is taken as an example, but in this embodiment, the pressure-sensitive switch SW2 is used. Yes.

すなわち、基板７と収容部材４の底面との間に、振動検出素子２における対象物との接触圧力を検知する感圧スイッチＳＷ２を設けたものである。図３（ａ）において、図１（ａ）と同一部分に同じ符号を付してその詳細な説明は省略する。   That is, a pressure sensitive switch SW2 for detecting the contact pressure with the object in the vibration detecting element 2 is provided between the substrate 7 and the bottom surface of the housing member 4. In FIG. 3 (a), the same parts as those in FIG. 1 (a) are denoted by the same reference numerals, and detailed description thereof is omitted.

感圧スイッチＳＷ２は、例えば図３（ｂ）に示すように、表面に導電体膜１１−１、１１−２が形成された基材１０−１、１０−２を、スペーサ１２ａ、１２ｂを介在して対向配置することで構成できる。基材１０−１、１０−２に圧力が加わると撓むことで導電体膜１１−１、１１−２が接触してスイッチがオンする。   For example, as shown in FIG. 3B, the pressure-sensitive switch SW2 includes base members 10-1 and 10-2 having conductor films 11-1 and 11-2 formed on the surface, and spacers 12a and 12b interposed. And it can comprise by opposing arrangement | positioning. When pressure is applied to the base materials 10-1 and 10-2, the conductor films 11-1 and 11-2 come into contact with each other by bending and the switch is turned on.

このような構成において、感圧スイッチＳＷ２で振動検出素子２を作動させ、対象物から離したときに停止させることにより、上述した実施の形態と実質的に同様な作用効果が得られる。   In such a configuration, by operating the vibration detecting element 2 with the pressure-sensitive switch SW2 and stopping the vibration detecting element 2 when it is separated from the object, substantially the same effect as the above-described embodiment can be obtained.

なお、上記実施の形態では、肉伝導マイクロホンや骨伝導マイクロホンのような人体の体導音を検出するものを例にとって説明したが、対象物に接触させて振動を検出するもの一般に適用できる。また、スイッチＳＷ１、ＳＷ２で振動検出素子２のオン／オフ状態を切り替える場合を例に取って説明したが、例えば対象物に接触させたときは高感度、離し時には低感度というように、感度を切り替えるようにしても良い。   In the above-described embodiment, an example of detecting body-conducted sound of a human body such as a meat conduction microphone or a bone conduction microphone has been described as an example. However, the present invention can be generally applied to those that detect vibration by contacting an object. In addition, the case where the on / off state of the vibration detecting element 2 is switched by the switches SW1 and SW2 has been described as an example. You may make it switch.
