Abstract
The utility model discloses a novel Bluetooth headset comprising a main control chip U1 in the Bluetooth headset and a matching functional circuit, wherein a magnetic induction switching control circuit is connected to a pin K4 of the main control chip U1. The novel Bluetooth headset of the utility model has the advantages of being energy-saving, environment-friendly, and long in service life.
Description
Technical field
The utility model relates to wireless communication technique application, a kind of novel bluetooth earphone particularly, and this earphone utilizes internal circuit work and magnetic induction function, can be when conveniently carrying out communication and answering, energy-conserving and environment-protective, increase the service life.
Background technology
At present, known bluetooth earphone is to consist of inner control circuit board (comprising charging inlet circuit, battery circuit, bluetooth transceiver module, audio-frequency assembly, key circuit, PAC circuit), loudspeaker, switch and volume button and shell.External key is various, and position is concentrated, and when answering call, user is inconvenient to operate, and sensitivity is too poor, and anti-tampering ability, and electric quantity consumption is very fast, to user, makes troubles.Owing to will modulating volume in use, change different operating state (such as listening song), the sheet metal being partly connected with the modulation circuit of internal circuit board, because access times are too much or oxidation, can damage and then cause loose contact normally to use.
Utility model content
The utility model, in order to address the above problem, has designed a kind of Novel Bluetooth earphone.
The purpose of this utility model is in order to overcome user when using bluetooth earphone communication, can not conveniently answer or the electric quantity consumption that causes of hanging up the telephone fast, and integral product short shortcoming in useful life.The utility model is that bluetooth earphone has increased a kind of function of utilizing magnetic induction to control product mains switch closure, can be in the operating state of moment connection or closed whole product, simultaneously, also retained traditional Bluetooth earphone circuit control system, improve greatly product and used accuracy and equal dual fail-safe control, extended the bulk life time of product.And base of this product mix, places convenient and safe.
Realizing above-mentioned purpose the technical solution of the utility model is, a kind of Novel Bluetooth earphone comprises main control chip U1 and supporting functional circuit thereof in bluetooth earphone, particularly at the K4 of main control chip U1 pin place, connects magnet inductive switch control circuit.
Described magnet inductive switch control circuit is by battery supply BATT
+, magnetic induction control chip U4 and switch control chip U2 tri-parts are electrically connected enough formations successively.
Described BATT
+by circuit, be connected with 3 pin of magnetic induction control chip U4,1 pin of magnetic induction control chip U4 is connected with 3 pin of switch control chip U2.
The 2 pin ground connection of described magnetic induction control chip U4.
Described magnetic induction control chip U4 is magnetic strength Hall chip DH481.
6 pin of described switch control chip U2 are connected with the K4 pin of main control chip U1 by 10K resistance R 1.
Between 3 pin of described magnetic induction control chip U4 and 1 pin, be connected with 100K resistance R 4.
The Novel Bluetooth earphone that utilizes the technical solution of the utility model to make; can greatly reduce the consumption of electric weight in the operating state of moment connection or closed whole product, the closed protective circuit of dual switch; guarantee the normal use work of product, extended the bulk life time of product simultaneously.
Accompanying drawing explanation
Fig. 1 is the circuit diagram of electromagnetic induction switch control circuit described in the utility model;
In figure, BATT
+-battery supply, U1-main control chip, U2-switch control chip, U4-magnetic induction control chip, R1-10K resistance, R4-100K resistance.
Embodiment
Below in conjunction with accompanying drawing, the utility model is specifically described, if Fig. 1 is the circuit diagram of electromagnetic induction switch control circuit described in the utility model, as shown in the figure, a kind of Novel Bluetooth earphone, comprise main control chip U1 and supporting functional circuit thereof in bluetooth earphone, particularly at the K4 of main control chip U1 pin place, connect magnet inductive switch control circuit.Wherein, described magnet inductive switch control circuit is by battery supply BATT
+, magnetic induction control chip U4 and switch control chip U2 tri-parts are electrically connected enough formations successively; Described BATT
+by circuit, be connected with 3 pin of magnetic induction control chip U4,1 pin of magnetic induction control chip U4 is connected with 3 pin of switch control chip U2; The 2 pin ground connection of described magnetic induction control chip U4,6 pin of described switch control chip U2 are connected with the K4 pin of main control chip U1 by 10K resistance R 1; Between 3 pin of described magnetic induction control chip U4 and 1 pin, be connected with 100K resistance R 4.
The embodiment of Novel Bluetooth earphone described in the utility model is:
When magnetic induction control chip U4 is during near magnetic base, U4 does not work, 3 pin of magnetic induction control chip U4 and 2 pin conductings.After U4 quits work, 3 pin of U4 and 1 pin disconnect, and stop power supply to the 3rd pin of switch control chip U2, and U2 the 3rd pin no-voltage is supplied with the 6th pin, the K4 pin undertension of main control chip U1, so main control chip U1 quit work, thereby complete machine quits work.Therefore after magnetic induction control chip U4 senses base magnetic force, battery supply will disconnect, and the 3rd pin of magnetic induction control chip U4 and the 1st pin disconnect, BATT
+stop to bluetooth equipment power supply, equipment is in off-mode, and bluetooth earphone stops to communication apparatus signal transmission, makes bluetooth equipment and communication apparatus in power save mode, has saved the consumption of electric energy.When bluetooth earphone leaves magnetic base, magnetic induction is controlled U4 and is opened and conducting, i.e. magnetic induction control chip U4 the 3rd pin and the 1st pin conducting, battery supply BATT
+to bluetooth equipment power supply, make bluetooth earphone moment open and connect communication apparatus, and make bluetooth equipment and communication apparatus in normal operating conditions.Adopt the bluetooth earphone of such scheme to there is convenient communicating party formula easily, save energy and reduce the cost, reuse highly sensitive, avoid mechanical switch to occur because of not smooth problems of communication such as loose contact, dirty, oxidations.
Technique scheme has only embodied the optimal technical scheme of technical solutions of the utility model; those skilled in the art have all embodied principle of the present utility model to some changes that wherein some part may be made, within belonging to protection range of the present utility model.
