Abstract
The invention relates to a speaker, in particular to a rotary speaker which mainly comprises a base, a main rotating shaft, an auxiliary rotating shaft, three loudspeaker systems, a triangle support plate and a rotary switch. When in use, sounding faces of the three loudspeaker systems respectively face to three different directions so as to realize multidirectional sounding, thereby meeting the requirements on audio-visual sound quality from different angles. When not in use, the sounding faces of the three loudspeaker systems are screwed in the base system of the speaker to prevent dust fromentering the speaker.
Description
Technical field
The present invention relates to a kind of audio amplifier, relate in particular to a kind of rotatable sound box.
Background technology
At present, known audio amplifier is made up of voice box casing and the speaker system that is arranged in the housing, and both are fixed together.The audio amplifier of this form has following two shortcomings: (1) is because outside the grid on existing audio amplifier surface was exposed to, voice box casing was hidden dust easily throughout the year.(2) because the loud speaker of existing audio amplifier is installed in a face of square or cuboid casing mostly, only sound to a direction, difficulty satisfies the demand of user's different angles to audiovisual tonequality.
Summary of the invention
At the shortcoming of prior art, the purpose of this invention is to provide a kind of rotatable sound box, solve the problem that existing voice box casing is hidden dust easily, only sounded to a direction.
To achieve these goals, technical scheme of the present invention is: a kind of rotatable sound box, comprise the audio amplifier support system and be installed in three speaker systems on three secondary rotating shafts of audio amplifier base that it also comprises rotary switch and gusseted plate that is installed on the main rotating shaft and the rotary switch that is fixed on rotary switch upper surface lid.
In such scheme:
Described audio amplifier support system comprises audio amplifier base, a main rotating shaft and three secondary rotating shafts.Main rotating shaft is fixed on the base center, and three secondary rotating shafts and main rotating shaft equidistantly are evenly distributed on around it, are fixed on the base.Four rotating shafts are hollow cylinder, and its hollow part is used for cloth tone frequency channel wire and power line.The base bottom is provided with audio frequency and power supply external tapping.
Described speaker system has cylindrical hole, and sky is enclosed within on each secondary rotating shaft, and there is bearing pin on the top, stretches in the groove that rotary switch offers, by its folding of Spin Control of rotary switch.
Described gusseted plate center has circular hole, is enclosed within the main rotating shaft outer surface, and there is boss lower surface, three angles, stretches into three secondary rotating shaft hollow cylinder internal surface of hole, strengthens the stability of total.
Described rotary switch center has circular hole, is enclosed within the main rotating shaft outer surface.The main rotating shaft end has screw thread, cooperates with nut, makes rotary switch to rotate, and can not move axially.Rotary switch lower surface indent is so that the gusseted plate is laid.End face has groove simultaneously, also control loudspeaker system rotation when making rotary switch adjusting volume and Switching Power Supply.
Described structure is not when using, and the grid of three speaker systems one side precession audio amplifier support system avoids dust to enter.During use, screw out the audio amplifier support system, three speaker systems are 120 degree and distribute, and sound to three directions, satisfy the demand of user's different angles to audiovisual tonequality.The angle that screws out is big more, and volume is big more.
The invention has the beneficial effects as follows, solve the problem that existing voice box casing is hidden dust easily, only sounded to a direction.

Embodiment
Below in conjunction with accompanying drawing, the present invention is specifically described.
As shown in Figure 1, Rotary Speaker of the present invention mainly is made up of base (01), main rotating shaft (16), secondary rotating shaft (02,03,04), speaker system (06,08,18), gusseted plate (13), rotary switch (12), rotary switch lid (11).Main rotating shaft (16) and secondary rotating shaft (02,03,04) vertically are fixed on the base (01).Speaker system (06,08,18) is enclosed within on the secondary rotating shaft (04,02,03) by the cylindrical hole that has separately.The circle hole sleeve that gusseted plate (13) has by the center is at main rotating shaft (16) outer surface, and boss (10,14, the 15) correspondence on three angles stretches into three secondary rotating shafts (04,02,03) hollow cylinder internal surface of hole, strengthens the stability of total.The circle hole sleeve that rotary switch (12) has by the center is at main rotating shaft (16) outer surface.The terminal screw thread of main rotating shaft (16) cooperates with nut, makes rotary switch (12) to rotate, and can not move axially.Rotary switch lid (11) is fixed on rotary switch (12) upper surface.As shown in Figure 2, the bearing pin (07,09,17) on the speaker system (06,08,18) respectively correspondence stretch into three grooves (20,21,19) that have on the rotary switch (12).Fig. 2 left side is the shaft section figure of unused state of the present invention, when rotary switch (12) clockwise rotates certain angle, electric power starting, when sound increases gradually, three bearing pins (07,09,17) slide in the groove (20,21,19) of correspondence, make corresponding speaker system (06,08,18) rotate to an angle around the secondary rotating shaft (04,02,03) of correspondence.End-state is shown in Fig. 2 right side.Fig. 2 the right is the shaft section figure of user mode of the present invention.
As shown in Figure 3, when the present invention did not use, the pronunciation face of three speaker systems (face that some apertures are arranged among Fig. 4) screwed in the audio amplifier support system, avoids entering of dust.
As shown in Figure 4, when the present invention used, the pronunciation face of three speaker systems towards three different directions, was realized multi-direction pronunciation respectively, satisfied the demand of user's different angles to audiovisual tonequality.
