ACOUSTIC RECEIVER WITH INTERNAL SCREEN |
摘要 |
An acoustic apparatus includes a high frequency driver that has a first front volume and a low frequency driver that has a second front volume. The first front volume and the second front volume communicate with each other to form a common front volume. At least one acoustic resistance is placed between the first front volume and the second front volume. The acoustic resistance acts as a low pass filter. |
