Description

図２は、本発明の実施例に係るインサート型ヘッドホンの測定用装着部材と、従来のカプラを用いたときの周波数特性を比較して示している。図２において、破線は従来の測定結果、実線は本発明の実施例に係る測定用装着部材を用いた測定結果を示している。１０００Ｈｚ以上の周波数ではほぼ同じ測定結果であるが、１０００Ｈｚ以下、特に２００Ｈｚ以下になると、従来のカプラを用いた場合はハウジングの機械的な振動の影響が考慮できていないことがわかる。これに対し、本発明の測定用装着部材１では１０００Ｈｚ以下の筐体の振動による音圧レベルの変動が大きく、特に２００Ｈｚ以下では従来との音圧レベルの差が大きくなっている。 FIG. 2 shows a comparison of frequency characteristics when using a measurement mounting member of an insert type headphone according to an embodiment of the present invention and a conventional coupler. 2, dashed lines are conventional measurement results, the solid line shows the measurement results using the measuring attachment member according to an embodiment of the present invention. Although the measurement results are almost the same at a frequency of 1000 Hz or higher, it can be seen that when the frequency is 1000 Hz or lower, particularly 200 Hz or lower, the influence of mechanical vibration of the housing cannot be taken into account when a conventional coupler is used. On the other hand, in the measurement mounting member 1 of the present invention, the fluctuation of the sound pressure level due to the vibration of the casing of 1000 Hz or less is large , and the difference in the sound pressure level from the conventional one is particularly large at 200 Hz or less.
