The invention provides a wearable speaker system that realizes high presence through reproduction of bass. The wearable speaker system is equipped with an enclosure (101). A first speaker unit (102L)and a first opening part (104L), which is an end of a first bass reflex duct, are disposed in a first end region of the enclosure (101). A second speaker unit (102R) and a second opening part (104R),which is an end of a second bass reflex duct, are disposed in a second end region of the enclosure (101). The first and second speaker units (102L, 102R) each have a speaker (103) and a passive radiator (105) that faces in the opposite direction from the speaker (103). The space between the speaker (103) and the passive radiator (105) in each of the first and second speaker units (102L, 102R) is connected to a space inside the enclosure (101).

The invention discloses an oil production simulation system and a simulation method. The oil production simulation system comprises an oil production simulation device, a PLC (programmable logic controller) controller and a control unit; the control unit comprises a main control computer, a parameter machine and a picture processor; the oil production device is connected with the PLC controller, and the PLC controller is connected with the parameter machine through a serial port; the parameter machine and the picture processor are respectively connected with the main control computer through a communication network; the oil production simulation method includes PLC data collection, calculation of the main control computer and virtual presentation. According to the oil production simulation system and the simulation method provided by the invention, the shortcoming that the pipe network flowing condition is hard to calculate in real time by a traditional calculation method can be solved, pressure and flowing conditions of the pipe network can be calculated in real time, and simulation of leakage, blockage and super-pressure accident can be conveniently carried out; moreover, the floor area of the device is small, every student can intuitionally observe the response action of every gas production simulation device and really reach a highly simulation effect; thus the training scene feeling is enhanced and the training effect is improved.

The invention discloses a multichannel audio controlled dynamic seat platform, comprising a seat body, and further comprising a signal decoding driver arranged on the seat body, and a vibrating device controlling the vibration of the seat body according to output of the signal decoding driver. The vibrating device comprises a right front vibrator, a middle vibrator, a left front vibrator, a low frequency vibrator, a right surrounding vibrator, a left surrounding vibrator, a right back surrounding vibrator and a left back surrounding vibrator, wherein the signal decoding driver comprises an interface matched with the vibrating device. The seat follows the movie scene and motion closely, and the motion output of the vibrators does not need to be acquired in advance. The seat can automatically follow the surrounding musics of sound track 7.1 or 5.1 or sound track 2.1 and multi-channel in other encoding formats; the vibration responding times can reach 400 per second at most; and therefore, the infection and the liveness of movies and games are enhanced.
