For solving the problems of the technologies described above, the technical solution used in the present invention is a kind of osteoacusis of design and air transmitted oscillator, the lead-in wire that comprises a hollow housing and input electrical signal, the hollow central of housing is provided with a pole shoe, one end surfaces of pole shoe caves inward and forms a receiving space, and receiving space is placed with a permanent magnet; The outer of the fixedly connected vibrating reed of one end of housing, the interior other end of vibrating reed along fixedly connected pole shoe, the other end of housing is fixed with vibrating diaphragm, the inboard of vibrating diaphragm is connected with a coil, coil is embedded in the gap that forms between pole shoe and the permanent magnet, and all leave the space between coil and permanent magnet and pole shoe, coil links to each other with lead-in wire.
Described housing, vibrating reed, pole shoe, permanent magnet, coil, vibrating diaphragm coaxial line.
Described vibrating reed is rounded, and its center is a circular hole, and on have two centers symmetries but the deep-slotted chip breaker that do not communicate, the arc-shaped slot formation that each deep-slotted chip breaker does not wait by two radius and communicates.
The present invention also provides a kind of earphone, described earphone comprises an osteoacusis and air transmitted oscillator, wherein, described oscillator comprises the lead-in wire of a hollow housing and input electrical signal, the hollow central of housing is provided with a pole shoe, one end surfaces of pole shoe caves inward and forms a receiving space, and receiving space is placed with a permanent magnet; The outer of the fixedly connected vibrating reed of one end of housing, the interior other end of vibrating reed along fixedly connected pole shoe, the other end of housing is fixed with vibrating diaphragm, the inboard of vibrating diaphragm is connected with a coil, coil is embedded in the gap that forms between pole shoe and the permanent magnet, and all leave the space between coil and permanent magnet and pole shoe, coil links to each other with lead-in wire.
Described housing, vibrating reed, pole shoe, permanent magnet, coil, vibrating diaphragm coaxial line.
Described vibrating reed is rounded, and its center is a circular hole, and on have two centers symmetries but the deep-slotted chip breaker that do not communicate, the arc-shaped slot formation that each deep-slotted chip breaker does not wait by two radius and communicates.
Gentle conduction oscillator of osteoacusis of the present invention and earphone thereof are by being provided with vibrating reed and vibrating diaphragm, make voice signal produce vibration and produce the sense of hearing by osteoacusis by vibrating reed, or produce vibration by vibrating diaphragm and produce the sense of hearing by air transmitted, can not only make deaf people produce the sense of hearing, and can also produce the sense of hearing at the full frequency band of sound, compare existing single air transmitted earphone or bone conduction earphone and have outstanding advantage.
Description of drawings
The present invention is described in detail below in conjunction with embodiment and accompanying drawing, wherein:
Fig. 1 is the structural representation of people's ear;
Fig. 2 is the structural representation of a kind of osteoacusis of the present invention and air transmitted oscillator;
Fig. 3 is the structure chart of vibrating reed of the present invention.
Embodiment
See also Fig. 2.Osteoacusis of the present invention and air transmitted oscillator comprise housing 1, lead-in wire 2, pole shoe 3, permanent magnet 4, coil 5 and vibrating diaphragm 6, and the central axis of housing 1, lead-in wire 2, pole shoe 3, permanent magnet 4, coil 5 and vibrating diaphragm 6 all overlaps, i.e. coaxial line.Permanent magnet and pole shoe are magnet, form magnetic circuit system jointly.
The central hollow of housing 1, pole shoe 3 is positioned at the hollow central of housing, and one end mediad sunken inside forms a receiving space 31.Permanent magnet 4 places the central authorities of receiving space 31.
The outer of vibrating reed 2 is fixed on the lower end of housing, the interior other end along fixedly connected pole shoe 3 of vibrating reed 2.Drive housing 1 vibration during vibrating reed 2 vibrations and will vibrate and be sent to the auditory nerve generation sense of hearing by skull.Vibrating reed 2 is spring leafs, and when low frequency signal imported into, spring leaf can be passed to otica with message according to the signal vibration, passes to auditory nerve by otica again.In this specific embodiment, vibrating reed 2 is rounded, sees also Fig. 3.The center of vibrating reed 2 is a circular hole 21, and the outer rim of circular hole is the other end that the interior edge of vibrating reed 2 is fixed on pole shoe 3.The arc-shaped slot formation that the deep-slotted chip breaker 22 that has two centers symmetry on the vibrating reed 2 but do not communicate, each deep-slotted chip breaker 22 do not wait by two radius and communicate.Certainly, vibrating reed also can be other shape.
Vibrating diaphragm 6 is fixed on the other end of housing, and its when vibration drives the ambient air vibration, thereby and causes that by air vibration people's eardrum makes the people produce the sense of hearing.Its inboard is connected with a coil 5, and coil 5 is embedded in the gap that forms between pole shoe 3 and the permanent magnet 4, and all leaves the space between coil 5 and permanent magnet 4 and pole shoe 3, so that the vibration of coil.Coil 57 links to each other with lead-in wire, and external audio signal 7 is sent to coil 5 by going between.
This uses novel osteoacusis and air transmitted oscillator to can be assembled into earphone.
The operation principle of osteoacusis of the present invention and air transmitted earphone is as follows: osteoacusis and air transmitted earphone are placed people's ear, when lead-in wire 7 has the audio signal input, when audio signal during at high band, coil 5 vibrates under the effect in the magnetic field of permanent magnet and pole shoe formation, thereby drive vibrating diaphragm 6 vibrations, the vibration of vibrating diaphragm 6 causes the vibration of surrounding air and causes that thereby eardrum is sent to brain with voice signal and produces the sense of hearing that in this frequency range, the response of vibrating reed 2 is relatively poor.When audio signal during in the medium and low frequency section, the response of vibrating diaphragm 6 is very poor, vibrating reed 2 vibrations, and drive housing 1 vibration, thus cause the skull vibration, and vibration signal is sent to the brain auditory nerve by skull produces the sense of hearing.
Therefore, use osteoacusis of the present invention and air transmitted earphone, the voice signal of Low Medium Frequency section is sent to auditory nerve by osteoacusis and produces the sense of hearing, causes that eardrum is sent to auditory nerve and produces the sense of hearing thereby the voice signal of high band is sent to ear-drum by air transmitted.Not only can help the ear-drum sufferer to hear sound, and the combination by osteoacusis and air transmitted can realize the full range transmission of sound, realize real around music and seven-channel stereo music.
