Specific implementation mode
For the blue-tooth earphone structure of the utility model is described in detail, below with reference to attached drawing to the specific reality of the utility model
Example is applied to be described in detail.
Fig. 1 shows the structure of the bluetooth headset according to the utility model embodiment；Fig. 2 and Fig. 3 respectively illustrate basis
The battery structure and wired control box structure of the utility model embodiment.
As Fig. 1 to Fig. 3 jointly shown in, the bluetooth headset of the utility model embodiment, including earphone cable 1, be arranged in earphone
Two earplugs 2 at 1 both ends of line, and the wired control box 3 that is arranged on earphone cable 1；Wired control box 3 further comprise line traffic control shell 31,
The circuit board 32 being arranged inside line traffic control shell 31, and the Bluetooth chip 33 of setting over the circuit board 32；In each earplug 2
It is arranged there are one battery 21 and thermistor 23 in 21 side of battery is set, thermistor 23 for acquires respective side in real time
The Current Temperatures information of battery 21；In advance with the charging current of battery and temperature relation table, bluetooth core in Bluetooth chip 33
Piece 33 is used to acquire the temperature information of thermistor 23, and according to the temperature information of thermistor 23 and charging current and temperature
Relation table controls the charging current value of battery 21, and the charging current of bluetooth headset is controlled in safe range.
Specifically, earplug 2 further comprises earplug shell (not shown), the battery 21 being housed in earplug shell, in electricity
The side in pond 21 is provided with battery protecting plate 22, and temperature is then arranged in battery protecting plate 22 than more sensitive thermistor 23
On, the Current Temperatures information of respective side battery 21 is acquired by thermistor 23.
In addition, in addition to being previously written charging current and temperature relation off-balancesheet in Bluetooth chip 33, electric discharge can also be written
When temperature threshold, it is when bluetooth headset is discharged, the temperature of collected thermistor 23 and temperature threshold is (predetermined
Value) it is compared, i.e., when battery 21 discharges, according to the comparison result of the temperature information of thermistor 23 and temperature threshold, control
The discharge condition of battery 21 processed.
Wherein, when the temperature information of thermistor 23 is higher than temperature threshold, Bluetooth chip 33 controls bluetooth headset and closes,
And stop the discharge process of battery 21；In other words, when 21 discharge temp of battery is excessively high, indigo plant can be controlled by Bluetooth chip 33
Tooth earphone is closed, and explosion is prevented.
In a specific implementation mode of the utility model, warning device (figure can also be set on Bluetooth chip 33
In be not shown), when battery 21 occur short circuit or battery 21 temperature be higher than temperature threshold when, can be controlled by Bluetooth chip 33
Warning device carries out warning reminding, and simultaneously closes off bluetooth headset, prevents product from exploding because 21 temperature of battery is excessively high.
It should be noted that being additionally provided with the AD acquisition chips 34 be connected with Bluetooth chip 33, bluetooth over the circuit board 32
Chip 33 acquires the temperature information of thermistor 23 by AD acquisition chips 34.
Fig. 4 shows the charging bluetooth earphone principle according to the utility model embodiment；Fig. 5 shows new according to this practicality
The discharge principle of the bluetooth headset of type embodiment.
In conjunction with Fig. 1 to Fig. 5 jointly shown in, the bluetooth headset of the utility model embodiment passes through first in charging process
