Description
Technical field
It is specifically a kind of that there is the three-in-one function of osteoacusis touch feedback loudspeaker the invention belongs to Microspeaker field
Driver.
Background technique
Require function more and more based on wearable device currently on the market, volume requirement is smaller and smaller, and existing market
On wearable device need to realize that bone conduction function loudspeaker function and touch feedback driver functions generally require two even
It is that three sections of products are just able to achieve these three functions.Can wearable device realize haptic feedback functions when can converse by osteoacusis
And osteoacusis driver is allowed to issue that graceful polyphonic ring tone of moving-coil speaker, it is that we primarily solve the problems, such as.
Summary of the invention
Haptic feedback functions are realized when the present invention is to solve realizing osteoacusis call, are provided a kind of with osteoacusis
The driver of the three-in-one function of touch feedback loudspeaker.
The invention adopts the following technical scheme:
Driver with the three-in-one function of osteoacusis touch feedback loudspeaker, it includes contact chip, connection sheet, suspension system
System, elastic slice, the first vibrational system, the second vibrational system, PFCB first passage, PFCB second channel, the first voice coil, magnetic cover, vibration
Film and pressure ring, contact chip are fixedly connected with connection sheet, and connection sheet is fixedly connected with suspension, and elastic slice and suspension connect
It connects；First vibrational system includes pole piece and permanent magnet, and pole piece and permanent magnet bonding are integrally and below connection sheet；First voice coil
It is looped around outside the first vibrational system and is placed on the inside of magnetic cover, magnetic cover one end is fixed on elastic slice outer edge；Second vibrational system packet
The second voice coil and vibrating diaphragm are included, vibrating diaphragm is pressed on the magnetic cover other end by pressure ring, and the second voice coil is bonded on the inside of vibrating diaphragm and surround
In the first vibrational system bottom；PFCB first passage is connect with the first voice coil, and PFCB second channel is connect with the second voice coil.
The pole piece includes the first pole piece and the second pole piece, and permanent magnet includes magnet steel and T-type magnet steel, the first pole piece bonding
Between magnet steel and T-type magnet steel, T-type magnet steel another side bonds the second pole piece.
Advantages of the present invention has using having the design of prestressed suspension and bell mouth shape contact surface, can allow vibration
Bigger acoustic pressure is generated, builds on double magnet steel, bipolar sheets, which are built among driver, increases the BL of its driver, and aerodynamic force is more
Powerful, bone conduction function is stronger, and another group of voice coil and vibrating diaphragm are increased on the basis of osteoacusis and haptic feedback functions, it
Share a magnet steel so that it simultaneously but also with traditional moving-coil speaker function.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Specific embodiment
As shown in Figure 1, the driver with the three-in-one function of osteoacusis touch feedback loudspeaker, it includes contact chip 1, connects
Contact pin 2, suspension 3, elastic slice 4, the first vibrational system, the second vibrational system, PFCB first passage 14, PFCB second channel
15, the first voice coil 8, magnetic cover 5, vibrating diaphragm 6 and pressure ring 7, contact chip 1 are fixedly connected with connection sheet 2, connection sheet 2 and suspension
3 are fixedly connected, and elastic slice 4 is connect with suspension 3；First vibrational system includes pole piece and permanent magnet, and pole piece and permanent magnet bond
One is simultaneously located at below connection sheet, and ordinary circumstance inferior pole piece includes the first pole piece 11 and the second pole piece 13, permanent magnet include magnet steel
10 and T-type magnet steel 12, the first pole piece 11 be bonded between magnet steel 10 and T-type magnet steel 12,12 another side of T-type magnet steel bond the second pole
Piece 13；First voice coil 8 is looped around outside the first vibrational system and is placed in 5 inside of magnetic cover, and 5 one end of magnetic cover is fixed on 4 outside of elastic slice
Edge；Second vibrational system includes the second voice coil 9 and vibrating diaphragm 6, and vibrating diaphragm 6 is pressed on 5 other end of magnetic cover, the second sound by pressure ring 7
Circle 9 is bonded in 6 inside of vibrating diaphragm and is looped around the first vibrational system bottom；PFCB first passage 14 is connect with the first voice coil 8, PFCB
Second channel 15 is connect with the second voice coil 9.
When electric signal connects FPCB first passage, the first voice coil generates magnetic field.The first voice coil being powered and two polarity
Opposite permanent magnet magnet steel and T-type magnet steel generation electromagnetic induction, the first voice coil cutting magnetic line, since the first voice coil is fixed, forever
Magnet movement, by driving vibrational system vibration, the driving force that the first vibrational system generates can drive bone to vibrate, vibrate generation
Sound is received by human ear eardrum or phonophore again, and final sound is listened by human ear, and vibrational system can generate powerful acceleration, by
Very big in acceleration, vibration sense is also very strong, by the haptic feedback functions of intelligent wearable device, the seismaesthesia of driving force be easy to by
Human body receives.
When electric signal connects FPCB second channel, the second voice coil generates magnetic field.The second voice coil and T type magnet steel being powered produce
Raw electromagnetic induction, the second voice coil cutting magnetic line, at this time since T-type magnet steel is fixed, the second voice coil and diaphragm oscillations, the second vibration
System vibration pushes air movement to generate sound, and sound is listened by air borne by human ear.
