Description
Technical field
The present invention relates to a kind of electronic product, particularly, is a kind of radio.
Background technology
Volume adjusting is carried out using potentiometer more than common FM receiver in life, i.e., by adjusting the scribing on a slide rheostat, changes the electric current inside radio, so as to realize volume adjusting；Prolonged use can cause the resistive film on rheostat to wear and tear, in addition, the dust in the external world also easily falls on resistive film so that send noise when volume is adjusted.
The content of the invention
For the problems referred to above, the present invention provides a kind of contactless radio, and the contactless radio has longer service life, will not generating element abrasion；Meanwhile, affected little by dust.
To solve the above problems, the technical solution adopted in the present invention is：This contactless radio includes an energization solenoid, and the density of the solenoidal coil turn is along solenoid shaft to successively decreasing；In the solenoidal inside, there is an axially displaceable drive link along axis device；Magnetic field induction element is fixed with the drive link；The magnetic field induction element is electrically coupled to a volume control module outside the solenoid；The magnetic field induction element is not contacted with solenoid.
Preferably, the solenoid Ring-cylindrical housing is made by Heat Conduction Material, coil configuration is in housing outer peripheral face；In order to, in the radio course of work, the heat that coil is produced quickly be dispersed.
Preferably, the magnetic field induction element is made up of Hall element, in order to measure small changes of magnetic field, and then the sensitivity of volume adjusting is improved.
The invention has the beneficial effects as follows：Because the wire winding arrangement density on energization solenoid is different, the Distribution of Magnetic Field inside solenoid is uneven, and the magnetic field tapers off trend distribution along solenoid axis；Due to induced-current difference of the magnetic field induction element at different magnetic field, drive link is adjusted, magnetic field induction element is moved along solenoid axis, magnetic field induction element just can be caused to produce different electric currents, the current signal is delivered to the volume control module, so as to realize the control of volume.
During whole volume adjusting, magnetic field induction element does not contact solenoid, will not generating element abrasion；Meanwhile, the dust in machine will not produce considerable influence to magnetic field, therefore will not produce impact to volume adjusting, effectively extend wireless service life.
Description of the drawings
Fig. 1 is the perspective view of this contactless wireless one embodiment；
Fig. 2 is the end view drawing of embodiment in Fig. 1；
Fig. 3 is the solenoidal coil row Butut of this contactless radio.
Specific embodiment：
With reference to specific embodiment and accompanying drawing, the present invention is described in detail.
Embodiment
In the embodiment described in Fig. 1 to Fig. 3, this contactless radio includes an energization solenoid 1, and the Ring-cylindrical housing of the solenoid 1 is made by Heat Conduction Material；As shown in figure 3, the density of the coil turn of the solenoid 1 along solenoid shaft to successively decreasing；In the inside of the solenoid 1, there is an axially displaceable drive link 2 along axis device；Hall element 3 is fixed with the drive link 2；The Hall element 3 is electrically coupled to a volume control module outside the solenoid 1（Not shown in figure）；The volume control module is a power amplifier module, offset side of the Hall element 3 coupled to the power amplifier module, and the wireless source of sound is coupled to the signal end of the power amplifier module, the induced-current of the output of Hall element 3 determines the bias voltage of the offset side, so as to control the power amplifier module for the multiplication factor of sound source signal；The Hall element 3 is not contacted with solenoid 1.
The housing of energization solenoid is made by Heat Conduction Material, and when radio works, the heat that coil is produced quickly can disperse；As the wire winding arrangement density on energization solenoid 1 is different, so the Distribution of Magnetic Field inside solenoid 1 is uneven, the magnetic field tapers off trend distribution along 1 axis of solenoid；Due to induced-current difference of the Hall element 3 at different magnetic field, adjusting drive link makes Hall element 3 move along solenoid axis, just Hall element 3 can be caused to produce different electric currents, the current signal is delivered to the offset side of volume control module, so as to realize the control of volume；As Hall element 3 can sense small changes of magnetic field and produce induced-current, so the sensitivity of volume adjusting can be effectively improved.During whole volume adjusting, Hall element 3 does not contact solenoid 1, will not generating element abrasion；Meanwhile, the dust in machine will not produce considerable influence to magnetic field, therefore will not produce impact to volume adjusting, effectively extend wireless service life.
Presently preferred embodiments of the present invention is the foregoing is only, not to limit the present invention, all any modification, equivalent substitution and improvements within the spirit and principles in the present invention, made etc., be should be included within the scope of the present invention.
