Composite speaker device
专利汇可以提供Composite speaker device专利检索，专利查询，专利分析的服务。并且PURPOSE: To obtain a vivid sound field by compensating the perception time lag of the auditory sense against low frequencies by means of disposition of speakers by delaying th intermediate and high frequency components in comparison to the low frequency component solely by the speaker system.
CONSTITUTION: The speaker 2 for intermediate frequencies and the speaker 3 for high frequencies are installed in a position farther than that of the speaker 1 for low frequencies so that the sounds from the speakers 2 and 3 reach with delays. Assuming the distance from the speaker 1 to the one 2 to be d
1 and that from the speaker 1 to the one 3 to be d
2 , the relation is set at d
2 >d
1 , and at the same time, pipes 4 and 5 are provided on the front surfaces of the speakers 2 and 3 to prevent the sound from diffusing. The delay times of the sound due to the distances d
1 and d
2 are calculated based on the speed of sound to delay the intermediate and the high frequency components from the low frequency component by means of the speaker system only. And the vivid sound field can easily be obtained. In practical use, the depth of the speakers can be shortened by bending the pipe and by inserting a reflector.
