The invention provides an all direction open type sound box. The sound box comprises a base. A spherical shell comprising a vibrating diaphragm is fixed on the base. A left side surface and a right side surface of the spherical shell are symmetrically concave toward the direction of the center of the sphere, so as to form two sections of symmetrical horn pipes. The two sections of symmetrical horn pipes are mutually connected with each other in the spherical shell, so as to form a symmetrical horn pipe. A closing coil coaxial with the horn pipe is fixed on the surface of each section of horn pipe. The closing coil is distributed from the end of the horn pipe close to the center of the spherical shell to the end of the horn pipe close to the spherical surface of the spherical shell. A section of cylindrical electromagnet coaxial with the symmetrical horn pipe is fixed at the center of the interior of the symmetrical horn pipe. An exciting coil is wound on the surface of the electromagnet. The exciting coil is coupled on a power amplifier module and a power module arranged in the base. The all direction open type sound box has basically consistent auditory effect in all directions, and has high sound energy efficiency and large sound production power.

The invention discloses a safety window for an elevator top beam. The safety window slides in a sliding groove of a slide rail to realize opening and closing of a window opening; a locking mechanism is used for locking the safety window on the top beam, so the window opening can be stably closed by the safety window. Compared with the rotation open type safety window provided in the background art, the push-and-pull open type safety window provided by the invention has the advantages that: occupied space is reduced, the stipulation of the national standard for the opening direction of the safety window and the requirement that the safety window cannot be beyond edges of the top beam when the safety window is open are unnecessarily considered, and interference between the safety window andparts on the top beam is also avoided.
