Playback of audio signals.The characteristics of high-pitched speaker is the exquisiteness that sound can be expressed by the high-frequency signal of output, the different position of loudspeaker
Different play sound effect is then presented in design, and optimal high-pitched speaker installation site should maintain an equal level with human ear as far as possible, otherwise sound field effect
It is undesirable, directly influence user experience.
But projector on the market, loudspeaker are fixed on projection device body construction at present, and loudspeaker position is unadjustable, sound
Effect experience is very poor.
Utility model content
In order to solve the above-mentioned technical problem, the utility model provides a kind of high-pitched speaker rotating device, solves projection
The problem that loudspeaker position can not automatically adjust in instrument, the experience of viewing audio is poor.
The technical scheme adopted by the utility model is
A kind of high-pitched speaker rotating device, including main body rack and high-pitched speaker unit further include poke rod and automatic touching
Bill member, for realizing the closure and rise of high-pitched speaker unit；
Poke rod includes that upper end interlocks axle construction and lower end gearing axle construction；
High-pitched speaker unit includes horn main body, limit slot structure and rotation connection structure, the rotation connection structure with
Main body rack is hinged；
Poke rod upper end interlocks axle construction and automatic trigger unit is fitting to connection；
Poke rod lower end interlocks axle construction and limit slot structure is fitting to connection.
Automatic trigger unit includes motor and electric machine support, and motor connects by the way that bolt and electric machine support are fixed
It connects.
Electric machine support includes axial trough and fixed chip architecture, and the fixed chip architecture is bolted main described in projector
On body support frame, the axial trough is used to be sleeved and fixed the transmission shaft of motor.
Motor includes motor body and transmission shaft, and transmission shaft passes through electric machine support circular hole and poke rod is socketed.
The shape of horn main body is spherical top structure cover shape.
The beneficial effects of the utility model are:
A kind of high-pitched speaker rotating device of the utility model drives driving lever rotation by setting automatic trigger unit, drives
High-pitched speaker realizes the automatic closure of high-pitched speaker unit and rises.And the utility model structure is compact to design, reduces
Assembly complexity ensure that the consistency of the device volume production.In addition, the present apparatus is easy to operate, and it is practical, it can be widely applied to
Projection device field.
Detailed description of the invention
Specific embodiment of the present utility model is described further with reference to the accompanying drawing:
Fig. 1 is a kind of overall structure diagram of high-pitched speaker rotating device of the utility model；
Fig. 2 is the high-pitched speaker cellular construction schematic diagram of the utility model；
Fig. 3 is a kind of partial structural diagram of high-pitched speaker rotating device of the utility model.
Specific embodiment
It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase
Mutually combination.
In the present embodiment, a kind of high-pitched speaker rotating device, referring to Fig.1, the structure include: including projector main body bracket
1, high-pitched speaker unit 2, poke rod 3 and automatic trigger unit 4.Automatic trigger unit 4, high-pitched speaker unit 2 are both connected to master
On body support frame 1, automatic trigger unit 4 connects high-pitched speaker unit 2 by poke rod 3, and poke rod 3 and automatic trigger unit 4 are used
In the closure and rise of realizing high-pitched speaker unit.
As shown in Fig. 2, the shape of the horn main body 21 in the present embodiment is spherical top structure cover shape, loudspeaker unit is in figure
Raised configuration.
As shown in figure 3, the poke rod 3 in the present embodiment includes that upper end interlocks axle construction 31 and lower end gearing axle construction 32；
Poke rod upper end interlocks axle construction 31 and is socketed on the transmission shaft 412 of automatic trigger unit 4.Poke rod lower end interlocks axle construction 32
It is embedded into the limit slot structure 23 of high-pitched speaker unit 2, the two nested encryptions.
As shown in figure 3, the high-pitched speaker unit 2 in the present embodiment includes horn main body 21, fixed connection structure 22 and limit
Position slot structure 23.Rotation connection structure 22 and projector main body bracket 1 are hinged.
As shown in figure 3, the motor 41 in the present embodiment includes motor body 411 and transmission shaft 412；Electric machine support 42
Including axial trough 422 and fixinig plate 423, the fixinig plate 423 is bolted on projector main body bracket 1, the axial trough
422 for being sleeved and fixed the transmission shaft 412 of motor 41.
As a kind of embodiment of the utility model, a kind of high-pitched speaker rotating device working principle is as follows: working as user
