Abstract
The utility model provides an earphone that has high tone quality at high range, including engine body shell, be equipped with battery operated woofer and piezoelectric type high pitch loudspeaker in the engine body shell, wherein piezoelectric type high pitch loudspeaker involving vibrations board, be equipped with piezoelectric element on the vibration board, the last tubulose leading note hole that is equipped with of engine body shell, the piezoelectric type high pitch loudspeaker set up in under the leading note hole, make the direction of piezoelectric type high pitch loudspeaker output sound with the axle direction in leading note hole keeps unanimous. The utility model relates to an earphone can have high tone quality's sound in the output of high range.
Description
Technical field
The utility model relates to earphone, particularly relates to a kind of earphone at high range with high tone quality.
Background technology
Existing earphone can be divided into outer aural headphone and headphone substantially, and the two all has voice guide hole, so that the sound sent by loud speaker conducts to earhole.As shown in Figure 1, described earphone comprises body fuselage 1, electrodynamic type woofer 2 and piezoelectric type high pitch loudspeaker 3 is provided with in described body fuselage 1, wherein said piezoelectric type high pitch loudspeaker 3 is provided with oscillating plate 31a, described oscillating plate 31a is provided with piezoelectric element 31b, described earphone is also provided with voice guide hole 4, but voice guide hole 4 of the prior art is arranged on the position of departing from earphone body fuselage 1 center, and the direction of principal axis of the direction of principal axis of voice guide hole 4 and earphone body fuselage 1 inconsistent (direction of principal axis of described earphone body fuselage 1 refers to the above-below direction shown in Fig. 1), the voice output direction of described electrodynamic type woofer 2 and piezoelectric type high pitch loudspeaker 3 is all the direction of principal axis of body fuselage 1, because the bass directive property that described electrodynamic type woofer 2 sends is little, as shown in Fig. 1 (A), therefore its sound sent can be conducted by described voice guide hole 4, but the high pitch directive property that described piezoelectric type high pitch loudspeaker 3 sends is large, can reflect in described body fuselage 1, as shown in Fig. 1 (B), therefore its sound sent can produce decay, and the volume of being conducted by described voice guide hole 4 can diminish.Therefore there is the problem at high range output sound lower tone in earphone of the prior art.
Utility model content
In order to solve problems of the prior art, the utility model proposes a kind of earphone at high range with high tone quality.
To achieve these goals, the utility model proposes a kind of earphone at high range with high tone quality, comprise body fuselage, electrodynamic type woofer and piezoelectric type high pitch loudspeaker is provided with in described body fuselage, wherein said piezoelectric type high pitch loudspeaker involving vibrations plate, described oscillating plate is provided with piezoelectric element; Described body fuselage is provided with tubular guidewire sound hole, and described piezoelectric type high pitch loudspeaker is arranged at immediately below described voice guide hole, and the described direction of piezoelectric type high pitch loudspeaker output sound and the direction of principal axis of described voice guide hole are consistent.
Preferably, the outer toroid of described electrodynamic type woofer is provided with supporter, described supporter is arranged along the outer rim of described outer toroid, described supporter is connected with described oscillating plate, described oscillating plate is skewed after being connected to described supporter, and the direction of principal axis of the normal direction being arranged so that described oscillating plate at its inclination angle and described voice guide hole is consistent.
Preferably, also be provided with plate body in described body fuselage, described plate body is arranged at immediately below described voice guide hole, and the direction of principal axis of the normal direction of described plate body and described voice guide hole is consistent, described piezoelectric element is provided with conduit, and described conduit is connected with described plate body.
The beneficial effect of the program of the present utility model is that above-mentioned earphone can export the sound with high tone quality at high range.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further described.
As shown in Figure 2, the earphone having a high tone quality at high range involved by the utility model comprises body fuselage 1, electrodynamic type woofer 2 and piezoelectric type high pitch loudspeaker 3 is provided with in described body fuselage 1, wherein said piezoelectric type high pitch loudspeaker 3 involving vibrations plate 31a, described oscillating plate 31a is provided with piezoelectric element 31b; Tubular guidewire sound hole 4 is provided with outside described body fuselage 1, piezoelectric type high pitch loudspeaker 3 involved by the utility model is arranged at immediately below described voice guide hole 4, the described direction of piezoelectric type high pitch loudspeaker 3 output sound and the direction of principal axis of described voice guide hole 4 are consistent, to make described voice guide hole 4 sound that described piezoelectric type high pitch loudspeaker 3 exports can be conducted.
Fig. 3 shows the structural representation of the earphone of the utility model first embodiment.The sectional view that Fig. 3 (A) is earphone, Fig. 3 (B) shows the outer toroid 21 of electrodynamic type woofer 2 and the relation schematic diagram of supporter 32.As shown in the figure, be consistent to make the described direction of piezoelectric type high pitch loudspeaker 3 output sound and the direction of principal axis of described voice guide hole 4, following structure is adopted to realize above-mentioned purpose: the outer toroid 21 of described electrodynamic type woofer 2 is provided with supporter 32, described supporter 32 is arranged along the outer rim of described outer toroid 21, but not be arranged at the inside of described outer toroid 21, to ensure the voice output that can not hinder described electrodynamic type woofer 2, described supporter 32 is connected with described oscillating plate 31a, for supporting described oscillating plate 31a, described oscillating plate 31a is skewed after being connected to described supporter 32, and its inclination angle be arranged so that the normal direction of described oscillating plate 31a and the direction of principal axis of described voice guide hole 4 are consistent.
Fig. 4 shows the structural representation of the earphone of the utility model second embodiment.The sectional view that Fig. 4 (A) is earphone, Fig. 4 (B) shows the relation schematic diagram of plate body 33 and conduit 33a.As shown in the figure, be consistent to make the described direction of piezoelectric type high pitch loudspeaker 3 output sound and the direction of principal axis of described voice guide hole 4, following structure is adopted to realize above-mentioned purpose: in described body fuselage 1, to be also provided with plate body 33, described plate body 33 is arranged at immediately below described voice guide hole 4, and the normal direction of described plate body 33 and the direction of principal axis of described voice guide hole 4 are consistent, described piezoelectric element 31b is provided with conduit 33a, described conduit 33a is connected with described plate body 33, for supporting described plate body 33.In the concrete course of work, described oscillating plate 31a produces flexural vibrations by piezoelectric element 31b, and by these flexural vibrations, described conduit 33a can carry out piston type back and forth movement, therefore causes described plate body 33 to vibrate, thus produces sound.Because the normal direction of described plate body 33 and the direction of principal axis of described voice guide hole 4 are consistent, so the sound being vibrated by plate body 33 and produce just can not be decayed, can be conducted by described voice guide hole 4.
Earphone involved by the utility model can export the sound with high tone quality at high range.
