Description
Technical Field
The present invention relates to speakers, and more particularly, to a variable orientation speaker and a method of using the same.
Background
Loudspeaker commonly known as loudspeaker through the electric energy conversion to the electrical equipment of sound, through the electric energy transmission to coil of equidimension not, the coil produces magnetism and magnet and produces the interdynamic, causes the vibrating diaphragm vibrations, because the electric energy variation in size, the vibrating diaphragm vibration frequency and the amplitude that arouse constantly alternate for the vibrating diaphragm constantly changes the effect of air, forms abundant sound.
At present, the speaker all adopts fixed mounting means, and the sound production portion of speaker is towards specific direction. In different scene conditions, the direction of the loudspeaker needs to be adjusted, and if the direction of the loudspeaker is not adjusted, an ideal sound effect cannot be achieved. If the sound production direction of the fixed loudspeaker is adjusted, the work difficulty is greatly increased.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides a technical scheme for adjusting the sound production direction of a combined loudspeaker. The invention can realize automatic control and reduce the labor intensity and difficulty of adjusting the sounding direction.
The technical scheme provided by the invention is as follows:
the loudspeaker with variable orientation comprises a cylinder, wherein one end of the cylinder is provided with an opening, a plurality of loudspeakers are uniformly hinged on the opening end surface of the cylinder, a sliding plate is arranged in the middle of the cylinder, a guide plate is rotatably arranged at the bottom of the cylinder, the sliding plate is provided with strip-shaped limiting grooves corresponding to the number of the loudspeakers, a slide way is arranged on the guide plate, the slide way is formed by splicing two sections of mutually-connected grooves, one section of the groove is of a semi-elliptical structure, and the distance between the midpoint position of the groove and the central position of the guide plate is smaller than the distance between any end of the groove and the central position of the guide plate; the other section of groove is of a semi-elliptical structure, the distance between the middle point of the groove and the center of the guide plate is larger than the distance between any end of the groove and the center of the guide plate, pull rod hinge seats corresponding to the number of the loudspeakers are arranged on the slide way in a sliding mode, one end of each pull rod is hinged with the corresponding pull rod hinge seat, and the pull rods penetrate through the limiting grooves and are hinged with the side walls of the loudspeakers.
Specifically, the closed end of the cylinder body is internally and fixedly provided with a motor, and a rotating shaft of the motor is fixedly connected with the guide plate.
Specifically, the pull rod is hinged with the side wall of the horn through a hinge.
The invention also provides a using method of the loudspeaker with the variable orientation, the guide plate is rotated, the pull rod hinging seat sliding in the guide way on the guide plate is far away from or close to the central position of the guide plate, and the corresponding loudspeaker is driven to swing towards the radial direction of the guide plate by the pull rod.
The speaker has the beneficial technical effects that when the speaker is used, the speaker is fixedly arranged on a wall body or a supporting frame, the cylinder body faces a set direction, and the guide plate is rotated to enable the corresponding speaker to face the ground, so that the sound effect of transmitting sound to people on the ground in front is achieved. If the orientation direction of the loudspeaker needs to be adjusted, the direction of the corresponding loudspeaker towards the requirement can be realized by rotating the orientation of the guide plate, and the sound effect of sound transmission to people in different orientations is realized.

Detailed Description
As shown in fig. 1-3, the loudspeaker with variable orientation comprises a cylinder 1, wherein an opening is arranged at one end of the cylinder 1, and a plurality of loudspeakers 5 are uniformly hinged on the opening end surface of the cylinder 1. The middle part in the barrel 1 is fixedly provided with a sliding plate 3, and the sliding plate 3 is provided with scroll-shaped limiting grooves 10 corresponding to the number of the loudspeakers 5. The bottom in the barrel 1 rotates and is provided with a guide plate 2, and the guide plate 2 is provided with a slideway 9.
The slideway 9 is formed by splicing two sections of mutually connected grooves, wherein one section of the groove is in a semi-elliptical structure, and the distance between the middle point position of the groove and the central position of the guide plate 2 is less than the distance between any end of the groove and the central position of the guide plate 2; the other section of the groove is in a semi-elliptical structure, and the distance between the middle point of the groove and the center position of the guide plate 2 is larger than the distance between any end of the groove and the center position of the guide plate 2.
The slide way 9 is provided with pull rod hinging seats 7 corresponding to the number of the loudspeakers 5 in a sliding way, one end of each pull rod 6 is hinged with the pull rod hinging seat 7, and each pull rod 6 penetrates through the limiting groove 10 and is hinged with the side wall of each loudspeaker 5. In particular, the tie-rod 6 may be connected to the side wall of the horn 5 by a hinge 11.
The closed end of the cylinder body 1 is internally and fixedly provided with a motor 8, and a rotating shaft of the motor 8 is fixedly connected with the guide plate 2.
When the loudspeaker is used, the loudspeaker is fixedly arranged on a wall body or a supporting frame, the cylinder body 1 faces a set direction, the guide plate 2 is rotated to enable the corresponding loudspeaker 5 to face the ground, and the sound effect of sound transmission to people on the ground in the front is achieved.
During the use, starter motor 8 is rotatory, and drive deflector 2 is rotatory, and the articulated seat of pull rod 7 of slide 9 slidable on the deflector 2 receives slide 3 through pull rod 6 to its spacing for the articulated seat of pull rod 7 is kept away from or is close to the central point of deflector 2 and puts, and then swings towards the radial direction of deflector 2 through the loudspeaker 5 that 6 drives of pull rod correspond, reaches the technical purpose of adjustment loudspeaker 5 sound production orientation.
Set up 8 loudspeaker 5 in this embodiment, the same orientation equidirectional swing of loudspeaker 5 of the straight line both sides that the both ends of slot formed has realized the technological effect of adjustment loudspeaker 5 sound production orientation.
