Fig. 2 is embodiment two schematic diagram of my sound Hi-Fi sound-box.
Fig. 3 is in my sound Hi-Fi sound-box, an embodiment schematic diagram of magnetic post.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described:
In the embodiment one shown in Fig. 1, this voice Hi-Fi sound-box includes pedestal 1, has audio frequency input/output module in described pedestal 1; Being fixed with the bellows tube 2 being made up of elastic sheet on described pedestal 1, this elastic sheet can adopt resin sheet or the common sound basin scraps of paper; The surface of described bellows tube 2 is fixing is wound with axially extended vibrator coil 3, and described vibrator coil 3 is coupled in described audio frequency input/output module; The magnetic post 4 extended along bellows tube axis it is additionally provided with in the pipe of described bellows tube 2.
Above-mentioned voice Hi-Fi sound-box is operationally, vibrator coil 3 on tone currents output extremely described bellows tube 2, makes vibrator coil 3 and described magnetic post 4 act on and vibrate, thus driving described bellows tube 2 to vibrate, its vibrational structure is basically identical with trunnion, thus voice realizes high-fidelity reduction output.
In the embodiment two shown in Fig. 2, it is different in that with embodiment one: described bellows tube 2 is outside is also nested with a rigid pipe 5, the upper end shield of described rigid pipe 5 sets an enclosed globe shade 6 that can rotate freely around bellows tube 2 axis, bellows tube 2 is surrounded by described rigid pipe 5, enclosed globe shade 6 completely, so that the vibration sound wave that bellows tube 2 produces forms good audio mixing effect by interreflection in the space that rigid pipe 5, enclosed globe shade 6 are defined, make tone color more simple and honest; And described enclosed globe shade 6 offers a laterally broadcast hole 60, and to simulate human body oral area, make the audio broadcasted from broadcast hole closer to true man's audio, and can pass through to rotate described enclosed globe shade 6, flexible broadcast direction. It addition, described broadcast hole 60 can be made to have the perisporium extended in enclosed globe shade 6, this perisporium is bell mouth shape, to obtain better audio mixing effect.
Except above example, for described magnetic post 4, one embodiment is as shown in Figure 3, in Fig. 3, described magnetic post 4 is made up of iron core 41 and the magnet exciting coil 42 that is wound on iron core, field power supply is included in described pedestal 1, described field power supply is by the adjustment of the exciting current to described magnet exciting coil 42, change the magnetic induction of described magnetic post 4, to realize the adjustment (volume adjusting within the scope of described max volume of the max volume to described audio amplifier, then by changing the size realization of tone currents, namely the size changing described vibrator coil 3 sound intermediate frequency electric current realizes).
In magnetic post embodiment shown in Fig. 3, further, described iron core is divided into three iron core segmentations from top to bottom, separated by non-magnet material 43 between each iron core segmentation, a difference magnet exciting coil 42 around the home in each iron core segmentation, and magnet exciting coil 42 in each iron core segmentation is parallel with one another is coupled in described field power supply, described field power supply is constant-current source, and the total current namely exported is stable; Magnet exciting coil in each described iron core segmentation is equipped with on and off switch respectively, each on and off switch is coupled in the adjustment switch in described pedestal 1, the described switch that regulates is by connecting the described magnet exciting coil 42 of varying number, it is achieved regulate exciting current excitation length on described magnetic post 4; As, connect 1 magnet exciting coil, then the iron core segmentation corresponding to this 1 magnet exciting coil is carried out excitation by the output current convergence of described field power supply, then only corresponding with this iron core segmentation on described bellows tube 21 section produces significantly vibration;As connected 2 magnet exciting coils, then 2 sections of relative with these two magnet exciting coils on bellows tube 2 regions produce substantially vibration, for tubulose pendulum, the length participating in vibrating to it due to its eigentone is relevant, vibration length is more short, the ability of its reduction high frequency is more strong, otherwise, the ability of reduction low frequency is more strong (with Chord vibration, the feature of sound basin vibration is consistent), therefore, by connecting the described magnet exciting coil 42 of varying number, namely this audio amplifier of scalable is to high pitch, middle pitch, the reduction effect of bass, and for traditional sound basin audio amplifier, in order to realize height, in, the effect of bass regulates, typically require employing height, in, low three groups of speakers, the numerous and jumbled burden of structure, this loudspeaker box structure that is far from is succinctly convenient.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all within the spirit and principles in the present invention, any amendment of making, equivalent replacement, improvement etc., should be included within protection scope of the present invention.
