The center of each of the sound chambers is equal to the distance between the center and the air passage μ, and the rear end of the air passage 14 communicates with the rear portion 13 of the hemispherical shape of each of the sound chambers through the communication tube 16. The cross-sectional shape, size and length of each communicating tube are the same. The wide connection between the communication tube 16 and the respective sound chambers is equal to the width of the sound chamber side wall holes. Fig. 16 and Fig. 17 are views showing the structure of the speaker of the eighth embodiment of the present speaker system. (4) A schematic diagram expressed in the form of a stepped section. Fig. 16 and Fig. 17 show that the structure of the speaker body of the embodiment 8 is more than that of the seventh embodiment, and the fourth air passage 'communication tube of 9 mm is uniformly distributed along the circumference of the original air passage opening. The remaining surface is half _, and the rest of the structure is the same as that of the seventh embodiment. The four airways have two air channels arranged on the symmetry plane of any two adjacent sound chambers, and the other two air channels are arranged along the symmetry. ^ (4) The figure is a schematic structural view of the speaker of Embodiment 9 of the present speaker system. The speaker body i in this embodiment is a unitary type 'with no back cover. The rear portion 13 of the sound chamber 12 has a truncated cone shape. The connecting pipe is connected to the rear of the cubicle and exposed. Gamma upper flap (four) increased 嶋 2 closed. θ In the schematic diagram of the first embodiment of the present creation speaker system shown in Fig. 19, two speaker groups 18 are installed (in the figure, only the U, 印 U mother microphone group 18 is composed of two speaker units 3. The shape of the side wall of the chamber 12 is such that the rear portion of the cylindrical shape u^g to 12 is connected by the communication tube 16. The through air passage 14 communicates with the outside of the front end surface of the cabinet body. The following describes the working principle of the present creation. The inside of the speaker in 1 is composed of two chambers 12 丄u L 12b and a connecting tube 16 to form a vibrating cavity. The two ends of the resonant cavity are mounted with a sound, such as a diaphragm separation of the horn unit. Open the air between 9 M310548 in the cavity and the outside of the speaker 1. When the speaker is applied with an electrical signal, the diaphragm of the speaker unit is driven to vibrate back and forth, and the sound waves A and sound waves generated on the front side of the diaphragms of the two speaker units 3a and 3b. β propagates to the surrounding space outside the casing; the sound waves a and sound waves b generated on the rear side of the diaphragms of the speaker units 3a and 3b are respectively transmitted to the rear end of the speaker unit at the other end in the resonant cavity, and two columns are formed in the resonant cavity. Amplitude, frequency, propagation speed The same sound wave propagating in the opposite direction. Two columns of coherent sound waves interfere with each other in the resonant cavity; in the resonant cavity, the integrated acoustic wave motion is shouted. In the sound wave motion of the integrated circuit, the key one is the resonant cavity_sound wave interference speaker unit. When the middle-column acoustic wave reaches the rear side of the diaphragm of the other speaker unit in the resonant cavity, the acoustic wave directly and efficiently interferes with the diaphragm. Since the two speaker units are connected in parallel When the source is connected, the diaphragms of the two speaker units are the same, the amplitude is the same, and the phase is simple. Because the diameter and length of the resonant cavity are fixed, the diaphragm and diaphragm are in the working state. _ Distance is constant follow the input of the electrical bribery, the sound wave in the resonant cavity _ transport is also constant correction. The structure of the fresh speaker body! Size can change the effect of the sound wave delay, so that the radiated sound wave and the adjacent When the diaphragms meet, the phases are in phase, and the direction of propagation of the sound waves is in harmony with the vibration direction of the adjacent film. The diaphragm of the radiated sound wave is driven by the electrical signal, and the vibration rate is sensible. Vibration The film amplitude i is large, and the sound energy of the speaker on the back side of each speaker in the system is effectively radiated (4). The sound energy is radiated out of the speaker box through the diaphragm of the side adjacent speaker. ° The second embodiment of the present invention is based on the present invention. In addition to the airway 14. Sound waves 3 and sound waves in the sound chamber have a fine air 塾 effect, M310548 and form a positive sound wave A and B with the diaphragm of each speaker group to enhance the playback low frequency characteristics of the speaker. 5 In-phase acoustic wave C, the sound chamber side of most embodiments of the present invention adopts a cylindrical structure, and / / constitutes a whole substantially non-planar sound chamber to minimize the phonogram wave = is hemispherical, Mixed sound pressure, so these implementations of the current technology to improve the system pressure advantage.
