Specific embodiment
With reference to the accompanying drawings and examples, the structurally and functionally principle of the utility model is described further:
Embodiment one
It is the vibration-sound generating device on a kind of steering wheel provided by the embodiment of the utility model shown in Fig. 1 ~ 4.Such as Fig. 1 institute
Show, be provided with display module on the steering wheel, display module includes display 20 and screen 10.Steering wheel generally comprises annulus
The handshake part of shape, and it is located in the middle coupling part, display module is located at coupling part.Preferably, screen 10 is to touch
Screen, which can be instead of the mechanical key in conventional truck, and makes steering wheel with multiple functions.
As shown in Fig. 2, steering wheel includes bracket 30, bracket 30 is arranged inside steering wheel.The lid of screen 10 is located at bracket
Accommodating cavity 50 is formd on 30 and with bracket 30, display 20 is located in accommodating cavity 50.The vibration-sound generating device of the utility model
Including vibration unit and the linear actuators being arranged in accommodating cavity 50 40, wherein vibration unit includes screen 10.Pass through
The vibration of linear actuators 40 can drive the screen 10 of display module to vibrate, and be issued by 10 vibration-extrusion air of screen
Sound.Since steering wheel is close apart from driver, the sound which issues can be by driver clearly
It hears, and is not influenced by surrounding enviroment, ensure that the privacy of call.Compared with traditional loudspeaker sounding device, local oscillator
Dynamic sounding device is used to place earpiece without aperture, ensure that the complete and beautiful of interface.
Wherein, bracket 30 includes side wall 31 and support plate 32, and bracket 30 is fixedly connected on the steering wheel, and side wall 31 is as branch
The base support portion of frame 30, is fixedly connected with steering wheel.Support plate 32 is thin plate, is used as the loading plate of display module: aobvious
Show that device 20 is fixed in support plate 32, the setting of screen 10 is on the display 20.
In some embodiments, as shown in figure 3, linear actuators 40 can be arranged in the back side of screen 10, make linear
Actuator 40 directly drives the vibration of screen 10 and makes a sound.Screen 10 be similar to loudspeaker in vibration mould, but screen 10 generally by
Glass is made, therefore rigidity is larger, ineffective in vibration sounding.
Preferably, linear actuators 40 is arranged at support plate 32.Specifically, as shown in Fig. 2, linear actuators 40 is arranged
Deviate from the side of display 20 in support plate 32.Linear actuators 40 can be filled by modes such as stickup, welding, lock screws
Fit over support plate 32.Support plate 32 is driven to be vibrated when linear actuators 40 vibrates, support plate 32 drives screen 10 to vibrate again
Sounding.When vibration sounding, support plate 32 is vibrated and screen 10 is driven to vibrate together, and support plate 32 and screen 10 are similar to loudspeaking
Vibration mould in device, composite sound generating when being support plate 32 and screen 10 while being vibrated.
Compared with the back side that linear actuators 40 is set up directly on screen 10, the design of this structure makes support plate 32 and screen
Curtain 10 is vibrated simultaneously, and support plate 32 is generally made of plastic parts etc., and elasticity preferably, is conducive to it as diaphragm oscillations
Sounding.Support plate 32 has biggish area, forms cavity with steering wheel, and when support plate 32 is vibrated, support plate 32 is squeezed
The intracorporal air of chamber forms enough acoustic pressures.
The direction of vibration of linear actuators 40 can be parallel to the setting of screen 10, can be designed so that linear actuators in this way
Space is smaller on 40 occupancy steering wheel thickness directions, is conducive to the preferred arrangement of inner space.It is preferable that permitting in space
In the case where, in Fig. 2 ~ embodiment shown in Fig. 4, the direction of vibration normal to screen 10 of linear actuators 40 is arranged, line
Property actuator 40 direction of vibration normal to screen 10 be arranged when, bigger vibratory output can be obtained.
In the present embodiment, screen 10 includes visible area and frame region, and 10 back side of screen has ink layer, the oil
Layer of ink forms frame region, and the frame region is opaque.20 main body of display is located at below the visible area of screen 10.
Preferably, linear actuators 40 is located at the lower section of frame region.On the direction of vibration of linear actuators 40, vibration
Amplitude is maximum, can be to avoid the excessive vibration of display 20 by being arranged linear actuators 40 in frame region.
Alternatively, the specific location of linear actuators 40 can be as shown in figure 4, linear activated as alternative embodiment
The side in support plate 32 close to display 20 is arranged in device 40.Because steering wheel has biggish inner space, the party
Case is easy to implement.
In some embodiments, piezoelectric ceramic piece can be selected as actuator, but piezoelectric ceramic piece poor reliability.In this reality
It applies in example, linear actuators 40 is linear vibration motor (linear motor).Linear motor may include oscillator, elastic element and
Coil, wherein oscillator includes magnet.Elastic element is, for example, elastic slice, and oscillator is suspended in shell by the elastic slice of two sides.When
After coil is powered, coil generates magnetic field, on the magnet of magnetic fields to oscillator.Using electromagnetic action principle, electric energy is directly turned
The kinetic energy for changing vibrator line movement into makes oscillator make to move along a straight line back and forth under the magnetic fields of coil.
In the present embodiment, the side wall 31 of bracket 30 is additionally provided with stage portion 311, and the lid of screen 10 is located at stage portion 311.
The settable elastic damping part (not shown) at stage portion 311, elastic damping part are, for example, that elastic rubber material is made.
Audio drive circuitry is additionally provided at steering wheel, the linear actuators 40 is connect with audio drive circuitry.Driving
Circuit can also include power amplifier, when the drive part of linear vibration motor with audio signal and adds as loudspeaker
When power amplifier, corresponding sound can be issued.
Compared with the existing technology, the beneficial effects of the utility model are:
The utility model drives the screen of display module by linear actuators by the way that display module is arranged on the steering wheel
Curtain vibration, is made a sound by screen vibration-extrusion air.Its issue sound can clearly be heard by driver, and
It is not influenced by surrounding enviroment, ensure that the privacy of call.Compared with traditional loudspeaker sounding device, it is used to without aperture
Earpiece is placed, ensure that the complete and beautiful of interface.
Finally, it should be noted that above embodiments are only to illustrate the technical solution of the utility model embodiment rather than right
It is limited, although the utility model embodiment is described in detail referring to preferred embodiment, this field it is common
