大家知道,音响系统的频率响应对音质有明显影响,音调电路已成为高保真放音设备中不可缺少的组成部分.目前广泛使用的高低音控制电路,虽有简单、效果明显的特点,伹其作用毕竟有限.对于普通家庭,由于室内声压受到房间大小、家具数量及音箱位置等各种因素的影响,即使放音设备包括音箱在内具有十分平直的响应,在室内各处的声压仍将有很大的起伏.图1是在普通家庭房间内放音频响的一组实验曲线.曲线1是音箱在室内的声压频响,不均匀度高达30
We all know that the frequency response of the audio system has a significant impact on the sound quality, tone circuit has become an indispensable part of high-fidelity playback device currently widely used bass control circuit, although simple, obvious effect, The effect is limited.For ordinary families, due to indoor sound pressure by the size of the room, the number of furniture and speaker location and other factors, even if the playback device, including speakers, including a very flat response, the sound pressure throughout the room There will still be a great ups and downs Figure 1 is a set of experimental curves in the normal family room audio frequency response curve 1 is the sound pressure frequency response of the speaker room, unevenness up to 30
