Description
本発明は、コーン型スピーカーユニットのコーンの振動と、コーンを振動させる電気信号を相対的に同調させるエンクロージャーと、
分圧室を備えた整流装置に関する。The present invention relates to an enclosure that relatively synchronizes the vibration of a cone of a cone-type speaker unit and an electric signal that vibrates the cone,
The present invention relates to a rectifier including a partial pressure chamber.
マイクロホンは、振動板に音波を受けた時の圧力の状態の変化(強弱)を、電気信号に変換するもので、コーン型スピーカーは、電気信号をボイスコイルで磁力の変化(強弱)に変換して、マグネットの力でコーンを押し出し音波を発生させるもので、電気信号の強弱をマイクロホンの振動板の振動とすると、マイクロホンの振動板の振動とコーン型スピーカーのコーンの振動は、相対的に同調している。
音波は、空気の疎密波として表されるが、密の状態をマイクロホンの振動板が後方に圧力を受けた状態とすると、コーン型スピーカーではコーンを前方へ押し出した状態になり、疎の状態では、マイクロホンの振動板が圧力を受けた状態から、圧力を受ける前の位置に前方に戻る状態となり、コーン型スピーカーでは、コーンを押し出す前の位置に、後方へ戻る状態となる。
マイクロホンでは、振動板が密の状態から疎の状態なる時は、振動板の復元力により前方へ戻り、電気信号は強から弱になり、圧力を受ける前の位置でゼロになる。コーン型スピーカーも同様に、電気信号によりコーンを前に押し出す磁力が強から弱・ゼロになる事によりコーン(ダンパー)の復元力によりコーンが後方へ戻り密から疎の状態を作り出す。
この時、マイクロホンの振動板の復元にかかる負荷は、マイクロホンの形状や大きさを考慮すると、ほとんど無いと考えられるが、コーン型スピーカーでは、コーンで空気を振動させるために、コーンの前面・後面共、空気に接していて、密の状態にする時は磁力でコーンを押し出すので、空気による影響は磁力で補うことが出来るが、疎の状態にする時は、磁力が強から弱・ゼロに変化するだけで、コーンを引き戻す磁力は働かず、コーン(ダンパー)の持つ復元力だけで、疎の状態を作り出すことになる。
コーン型スピーカーユニットは、エンクロージャーに取り付けて鳴らすのが一般的であるが、コーン型スピーカーユニットのコーンが、電気信号で振動するときの強から弱・ゼロの変化により、コーンが後方(エンクロージャー内部)にコーン(ダンパー)の復元力によって戻ろうとするときに、コーン後部のエンクロージャー内の空気がバネとなって、コーンを前方(エンクロージャー外部)へ押し出そうとする力が働く。
これにより、エンクロージャー内部の空気が妨げとなり、マイクロホンの振動板が次の密の圧力を受ける位置まで戻るのにかかる時間と、コーンがマイクロホンの振動板と同じ相対的位置まで戻るのにかかる時間に、差が生じる。
この時間の差が、次の密の圧力を受けるまでに戻った、マイクロホンの振動板の位置と、次の強の電気信号を受けるまでに、コーン型スピーカーユニットのコーンが戻った位置に、相対的なずれとなって現れ、マイクロホンの振動板の振動と、コーン型スピーカーユニットのコーンの振動が、相対的に同調しない。
結果として、マイクロホンの振動板が受けて電気信号に変換した音と、スピーカーが電気信号をコーンの振動に変換して出した音は、違うことになる。
マイクロホンの振動板の振動と、相対的に同調した、コーン型スピーカーユニットのコーンの振動によるコーン後方の音を、共振させて低音部の位相を反転し、コーン前面の音と合わせて低音拡大する方式のエンクロージャーの場合、コーンの振動で発生する伝達の進行方向に整った空気の疎密波が、共振することによりあらゆる方向に影響を受け、そのままコーン前面の音と合わせて低音拡大した場合、耳障りな音となる。
この共振の影響を受けた疎密波を、減衰させずに、進行方向の疎密波に整える必要がある。The microphone converts the pressure state change (strong and weak) when the diaphragm receives a sound wave into an electric signal, and the cone type speaker converts the electric signal into a magnetic force change (strong and weak) with a voice coil. The force of the magnet pushes the cone and generates sound waves. If the strength of the electrical signal is the vibration of the microphone diaphragm, the vibration of the microphone diaphragm and the cone cone of the cone-type speaker are relatively synchronized. is doing.
Sound waves are expressed as air sparse waves, but if the microphone diaphragm is under pressure, the corn type speaker pushes the cone forward, and in the sparse state From the state in which the diaphragm of the microphone receives pressure, the microphone returns to the position before receiving the pressure, and the cone type speaker returns to the position before pushing out the cone.
In the microphone, when the diaphragm is changed from the dense state to the sparse state, the diaphragm returns to the front due to the restoring force of the diaphragm, and the electric signal is changed from strong to weak and becomes zero at a position before receiving the pressure. Similarly, the cone-type speaker also produces a sparse state due to the restoring force of the cone (damper) when the magnetic force that pushes the cone forward by an electric signal is changed from strong to weak / zero.
At this time, it is considered that there is almost no load on the restoration of the diaphragm of the microphone, considering the shape and size of the microphone, but in the case of a cone type speaker, the front and rear surfaces of the cone are used to vibrate the air with the cone. Both are in contact with air and push the cone with magnetic force to make it dense, so the effect of air can be compensated with magnetic force, but when making it sparse, the magnetic force is weak from strong to zero By simply changing, the magnetic force that pulls the cone does not work, and only the restoring force of the cone (damper) creates a sparse state.
The cone type speaker unit is generally attached to the enclosure and sounded, but the cone is rearward (inside the enclosure) due to the change from strong to weak / zero when the cone of the cone type speaker unit vibrates with an electrical signal. When the cone (damper) is restored by the restoring force of the cone, the air in the enclosure at the rear of the cone acts as a spring and acts to push the cone forward (outside the enclosure).
This obstructs the air inside the enclosure and reduces the time it takes for the microphone diaphragm to return to the next dense pressure position and the time it takes for the cone to return to the same relative position as the microphone diaphragm. , There will be a difference.
This time difference is relative to the position of the diaphragm of the microphone that has returned before receiving the next dense pressure, and the position to which the cone of the cone-type speaker unit has returned before receiving the next strong electrical signal. The vibration of the diaphragm of the microphone and the vibration of the cone of the cone type speaker unit are not relatively synchronized.
As a result, the sound received by the diaphragm of the microphone and converted into an electrical signal is different from the sound that the speaker converted from the electrical signal into cone vibration.
Resonates the sound behind the cone caused by the cone vibration of the cone type speaker unit, which is relatively synchronized with the vibration of the diaphragm of the microphone, inverts the phase of the bass part, and expands the bass sound together with the sound of the front of the cone. In the case of an enclosure of the type, when the air dense waves arranged in the traveling direction of the transmission generated by the vibration of the cone are affected in all directions by resonating and the bass sound is expanded together with the sound of the front of the cone, it is harsh Sound.
It is necessary to arrange the dense wave affected by this resonance into a dense wave in the traveling direction without being attenuated.
コーン型スピーカーユニットのコーンを振動させる電気信号とコーンの振動を相対的に同調させるために、コーン型スピーカーユニットのコーンの振動に影響を及ぼす空気の容積を、音の振動の伝達及び共振に必要最小限の容積にして、コーン型スピーカーユニットのコーン後方の位相が逆の音を取り込み、共振させて位相を反転して、
共振によりあらゆる方向に影響を受けた疎密波を、進行方向の疎密波に整えるため、空気の振動を流体として、振動する流体を、細分された一定の区間を抵抗無く通過させることにより、流体の分子の運動を制限して、安定させて、コーン前方の音と合わせて低音を拡大する方式とする。

構造の、分圧室を備えた整流装置とからなる、同調形スピーカーとなる。In order to relatively synchronize the vibration of the cone with the electrical signal that vibrates the cone of the cone type speaker unit, the volume of air that affects the vibration of the cone of the cone type speaker unit is necessary for the transmission and resonance of the sound vibration. With a minimum volume, the sound behind the cone of the cone type speaker unit takes in the opposite phase, resonates and reverses the phase,
In order to adjust the sparse wave affected in all directions by resonance to the sparse wave in the traveling direction, the vibration of air is passed through a certain subdivided section without resistance as a fluid by using air vibration as a fluid.
