Embodiment 1
[0017] Reference attached figure 2 , left and right channel speakers 1.1 and 1.2, passive radiator 2, two isolators 5.1, 5.2. The isolators 5.1 and 5.2 made of porous material brown silk board have a size that is just or slightly larger than the inner dimension of the cavity cross-section. The inner space 4 is divided into three parts: 4.1, 4.2 and 4.3, and the mutual transmission of sound waves between the three sub-spaces 4.1, 4.2 and 4.3 must pass through the isolators 5.1 and 5.2. When the left channel speaker is fed with medium and high frequency signals, front and rear sound waves are generated, in which the backward sound waves pass through the sub-space 4.1, pass through the isolator 5.1 and are attenuated into the sub-space 4.3, and then encounter the isolator 5.2 after passing through 4.3, and pass through The isolator 5.2 is attenuated and reaches the sub-space 4.2. At this time, the sound wave passes through the two isolators and is attenuated twice, which is alre...
Embodiment 2
[0019] Reference attached image 3 , in the attached figure 2 On the basis of the design, the separator 5.3 made of porous material is added, and the side parallel to the drawing surface of 5.3 is closely attached to the inner wall of the cavity 3 . The setting of the sub-space 4.3 is to ensure the normal vibration of the radiator 2 and leave enough room for the amplitude. At this time, most of the backward sound waves of the left channel will be attenuated by the isolators 5.1, 5.3 and 5.2, and only a small part can pass through the sub-space 4.3, bypass the isolator 5.3, pass the attenuation of the isolators 5.1 and 5.2, and reach the right channel speaker. . Due to the large width of the isolator 5.3, a part of the backward sound wave reaches another channel speaker after being attenuated by 5.1, 5.2 and 5.3, and the intensity can be ignored; the other part of the sound wave bypasses the isolator 5.3 through the space 4.3 and is isolated by 5.1 and 5.2 After the attenuat...
Embodiment 3
[0021] Reference attached Figure 4 , this solution is an improved design for the structure using two passive radiators at the front and rear. Left and right channel speakers 1.1 and 1.2, two front and rear passive radiators 2, and three isolators 5.1, 5.2 and 5.3 form an "I" shape, in which the sides of 5.1 and 5.2 are closely attached to the inner wall of the cavity 3, and the sides of 5.3 are parallel The two sides on the drawing surface are also in close contact with the inner wall of the cavity 3, so that when the sound waves are transmitted between the separated spaces 4.1, 4.2 and 4.3, they must pass through the isolator. Most of the middle and high frequency parts of the backward sound waves of the left channel are seriously attenuated by the isolators 5.1, 5.2 and 5.3, and the component reaching the speaker of the right channel is very small; while the other small part of the backward sound waves passes through the isolators 5.1 and 5.2 , bypassing the isolator 5.3 t...
