Abstract
A mobile phone includes a shell and a long piezoelectric oscillator, one end of which is connected on the shell to drive the shell to vibrate.
Description
Technical field
The present invention relates to a kind of mobile phone.
Background technology
Mobile phone utilizes electromagnetic motor traditionally so that mobile phone produces vibration when being set at vibration mode.These motors are relatively expensive, volume is insecure greatly and to a certain extent.
Summary of the invention
The present invention manages to provide a kind of mobile phone with improved vibrator.
According to the present invention, a kind of mobile phone is provided, described mobile phone comprises shell and elongated piezoelectric vibrator, described piezoelectric vibrator one end is connected on the described shell, uses so that shell produces vibration.
The drive circuit that preferably contains one or more battery and piezoelectric vibrator in the described shell.
Described piezoelectric vibrator preferably includes elongated deformable bonding jumper and the elongated ceramic component that is bonded at least one side of described bonding jumper.
Described piezoelectric vibrator preferably has and is bonded to the elongated ceramic component on each side in two opposite sides of described bonding jumper.
Ceramic component described or that each is elongated preferably has plate-like shape.
Described two elongated ceramic components are preferably in that to be orthogonal to described two elements polarized on the planar opposite direction separately.
Described drive circuit decision design is in order to cause the single order crooked syntony in described vibrator.
Therefore might provide a kind of mobile phone with vibrator, described vibrator has simple structure, compact size, high reliability and high effect.
Description of drawings
Below, only also in conjunction with the accompanying drawings a preferred embodiment of the present invention is described by example, wherein:
Fig. 1 is the cutaway view according to a part of shell of an execution mode of mobile phone of the present invention;
Fig. 2 shows the enlarged drawing of the mode of operation of piezoelectric vibrator as shown in Figure 1.
Embodiment
At first referring to Fig. 1, there is shown the part of mobile phone outer casing or housing 10 and elongated piezoelectric vibrator 11, described piezoelectric vibrator one end for example by binding agent, is fixed on the inner surface of described shell 10.Because the vibration that can have influence on to described shell transmits, therefore the position of the fixture between described shell 10 and described vibrator 11 is very important, but the enclosure base according to described mobile phone design is depended in described position, and need make compromise proposal according to free space.Described fixture is preferably the form from the extended firm relatively post 14 of the inner surface of described shell 10, is sent to shell 10 so that will vibrate from vibrator 11.Described post 14 fully separates vibrator 11 and described shell, and the free end of described vibrator touches described shell to avoid in use.
Described vibrator 11 comprises usually the elongated ceramic component 13 on each side in elongated deformable bonding jumper 12 that is become by steel, aluminium or copper and two opposite sides that are bonded in described bonding jumper 12.
Described bonding jumper 12 has rectangle or square cross section, and described ceramic component 13 has tabular configuration.Described ceramic component 13 makes that in that to be orthogonal to described element 13 polarized on the planar opposite direction separately one of them ceramic component can expand when being coupled with ac voltage signal, and another contraction, and vice versa, so that bonding jumper 12 is crooked back and forth, shown in the arrow among Fig. 2.
Shown in vibrator 11 by the power supply of one or more battery of mobile telephone, and the drive circuit (not shown) of piezoelectric vibrator 11 is set in the described shell 10.
Described design of drive circuit is in order to apply the ac voltage signal of certain frequency (usually in the 100Hz-300Hz scope) to described two ceramic components 13, it is suitable with the natural frequency of the first-order bending vibration of described vibrator 11 that described electric voltage frequency is adjusted to, so that cause the single order crooked syntony in described vibrator 11.This free end that will cause described vibrator 11 is crooked (as shown in Figure 2) back and forth, and with reaction force acting in conjunction at its stiff end place, make described shell 10 produce vibration.
Above-mentioned execution mode only provides in the mode of example, and the various modification of those skilled in the art's easy to understand in not departing from the scope of the present invention that is limited by claims.For example, described vibrator can comprise elongated deformable bonding jumper, and described bonding jumper has the elongated ceramic component that only is bonded on described bonding jumper one side.Simultaneously, described or each ceramic component can comprise two or more piezoelectric material layers.
Claims (8)
