Working condition, meanwhile, also remain traditional Bluetooth earphone circuit control system, greatly improve product using accuracy and
Equal to dual fail-safe control, the bulk life time of product is extended.And one base of the product mix, is placed convenient and safe.
Realize above-mentioned purpose the technical scheme is that, a kind of novel Bluetooth earphone, including master control core in bluetooth earphone
Piece U1 and its supporting functional circuit, particularly connect magnet inductive switch control circuit at main control chip U1 K4 pin.
The magnet sensing fast valving control circuit is by battery supply BATT+, magnetic induction control chip U4 and switch control
The parts of coremaking piece U2 tri- are electrically connected enough compositions successively.
The magnetic induction control chip U4 is magnetic strength Hall chip DH481.
The BATT+Be connected by circuit with magnetic induction control chip U4 3 pin, magnetic induction control chip U4 1 pin with
Switch control chip U2 3 pin connection.
The 2 pin ground connection of the magnetic induction control chip U4.
6 pin of the switch control chip U2 are connected by 10K resistance R1 with main control chip U1 K4 pin.
The effect that 100K resistance R4,100K resistance is connected between 3 pin and 1 pin of the magnetic induction control chip U4 be
U4 voltages are reduced when U4 works.
The novel Bluetooth earphone made using technical scheme, can connect or close whole product in moment
Working condition, greatly reduce the consumption of electricity, dual switch closure protection circuit, it is ensured that the normal of product uses work
Make, while extending the bulk life time of product.
Brief description of the drawings
Fig. 1 is the circuit diagram that electromagnetic induction switch of the present invention controls circuit；
Fig. 2 is the circuit diagram of earphone base charging circuit of the present invention；
In figure, BATT+- battery supply, U1- main control chips, U2- switch control chips, U4- magnetic induction control chip, R1-
10K resistance, R4-100K resistance.
Embodiment
The present invention is specifically described below in conjunction with the accompanying drawings, if Fig. 1 is electromagnetic induction switch control electricity of the present invention
The circuit diagram on road, as illustrated, a kind of novel Bluetooth earphone, including main control chip U1 and its supporting function electricity in bluetooth earphone
Road, particularly connects magnet inductive switch control circuit at main control chip U1 K4 pin.Wherein, the magnet inductive switch control
Circuit processed is by battery supply BATT+, magnetic induction control chip U4 and the parts of switch control chip U2 tri- be electrically connected successively
Enough constitute；The BATT+Be connected by circuit with magnetic induction control chip U4 3 pin, magnetic induction control chip U4 1 pin with
Switch control chip U2 3 pin connection；The 2 pin ground connection of the magnetic induction control chip U4；6 pin of the switch control chip U2
It is connected by 10K resistance R1 with main control chip U1 K4 pin；It is connected between 3 pin and 1 pin of the magnetic induction control chip U4
100K resistance R4.
The embodiment of novel Bluetooth earphone of the present invention is：
First, it is placed on the magnetic induction switch control model on magnetic base
When the base of bluetooth earphone is magnetic base, if the magnetic induction control chip U4 of bluetooth earphone is close to magnetic force bottom
Seat, magnetic induction control chip U4 is in halted state, and U4 the 3rd pin and the 2nd pin are turned on, because the 2nd pin is grounded, so now the
3 pin, which stop turning on to the 1st pin, powers；When magnetic induction control chip U4 leaves magnetic induction area, i.e. U4 work, magnetic induction control core
3 pin of piece and the conducting of 1 pin give the pin of controlling switch U2 the 3rd there is provided power supply, and the 3rd pin and the 6th pin are turned on when U2 is in opening,
U1 K4 pin are supplied electricity to, main control chip U1 normal works, complete machine is started working and normally used.Therefore as magnetic induction control chip U4
Sense that battery supply will disconnect after base magnetic force, i.e., magnetic induction control chip U4 the 3rd pin and the 1st pin disconnect, BATT+Stop
Only powered to bluetooth equipment, equipment be in off-mode, bluetooth earphone stop to communication apparatus transmit signal, make bluetooth equipment and
Communication apparatus is in power save mode, saves the consumption of electric energy.When bluetooth earphone leaves magnetic base, magnetic induction control chip
U4 is worked, i.e., the pin of magnetic induction control chip U4 the 3rd and the 1st pin are turned on, battery supply BATT+Powered to bluetooth equipment, make bluetooth
Earphone moment opens and connects communication apparatus, and bluetooth equipment and communication apparatus is in normal operating conditions.Using above-mentioned side
The bluetooth earphone of case has convenient easily communicating party formula, energy-saving, reuse sensitivity high, it is to avoid mechanical switch
Because occurring the problem of the communication such as loose contact, dirty, oxidation is not smooth.
2nd, it is placed on the electrical contact switch control model on base
When the base of bluetooth earphone is non-magnetic base, if bluetooth earphone is placed on the base, earphone base charging electricity
ENG and the GND short circuit on road, as shown in Fig. 2 now the ENG1 in Fig. 1 is earthed circuit, so as to drag down towards main control chip U1
K4 pin voltages, U1 is stopped.Complete machine is stopped.When bluetooth earphone leaves base, END and GND disconnects short circuit state,
Now the ENG1 in Fig. 1 is not at ground state, and the K4 pin voltage towards main control chip U1 is normal, the normal works of main control chip U1
Make, bluetooth earphone is connected rapidly and in running order with communication apparatus
3rd, pattern is carried with
When earphone belongs to the state carried with, user can manual toggle switch to ON grades opening switch control chips
U2, bluetooth earphone can be matched moment with communication apparatus, and normal work, be able to can be conversed by MFB is strong during incoming call, volume
It can be adjusted by VOL+ or above and below VOL-, listen often can be selected during song as bent above and below VOL+ or VOL- progress.
By above-mentioned embodiment, novel Bluetooth earphone of the present invention can be with magnetic base or medium base
Support the use together, also can individually carry with and use, occupation mode is flexibly light.
Above-mentioned technical proposal only embodies the optimal technical scheme of technical solution of the present invention, those skilled in the art
Some of which part may be made some variation embodies the present invention principle, belong to protection scope of the present invention it
It is interior.
