Bluetooth headset is a present widely used earphone, and its form is various, can avoid loaded down with trivial details wired connection, and the mode through wireless transmission is used extensively in the crowd in practitioner fields such as driver, transportation.

However, the existing bluetooth headset generally only can play a role of transmitting sound through the bluetooth unit, and cannot control the sound and answer the call, and particularly, the risk of driving is undoubtedly increased because a driver needs to take up a mobile phone to operate when answering the call in the driving process.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model aims at providing a two accuse earphones, the utility model discloses a change that detects the electric capacity of the second metal film that the ear was supported goes into and triggers the built-in MCU chip of earphone, judges whether the earphone wears into the ear, starts earphone functional mode. The change of the capacitance capacity is sensed through the first metal film, the MCU chip arranged in the earphone is triggered by utilizing the variable quantity, and after the MCU chip is triggered, the MCU chip arranged in the earphone controls the volume of the mobile phone, the answering call and other related functions through the Bluetooth unit. The utility model discloses need not directly operate the cell-phone, directly control through the earphone, convenient and fast has increased bluetooth headset's practicality.

The utility model discloses an above-mentioned technical problem is solved to following technical means:

the utility model discloses a double-control earphone, which comprises an earphone body, wherein the earphone body is divided into a control handle, a circuit cavity arranged at one end of the control handle, and an earplug fixedly connected with the circuit cavity, the earplug is divided into an earlobe and an ear support fixedly connected with the earlobe, one side of the ear support is provided with a sound hole, a force sensor is arranged in the control handle, the earlobe is provided with a first metal film, the ear support is provided with a second metal film, an MCU chip, a Bluetooth unit, a first capacitance detection chip and a second capacitance detection chip are fixedly arranged in the circuit cavity, the output end of the first metal film is connected with the input end of the first capacitance detection chip, the output end of the second metal film is connected with the output end of the second capacitance detection chip, the output ends of the first capacitance detection chip and the second capacitance detection chip are both connected with the input end of the MCU chip, the output end of the force sensor is connected with the input end of the MCU chip, the output end of the MCU chip is connected with the input end of the Bluetooth unit, a loudspeaker is arranged in the sound hole, and the output end of the MCU chip is connected with the input end of the loudspeaker. The MCU chip, the Bluetooth unit, the first capacitance detection chip and the second capacitance detection chip are all powered by button lithium batteries installed in the circuit cavity.

Further, the Bluetooth unit adopts a QCC5100 type Bluetooth chip.

Furthermore, the first capacitance detection chip and the second capacitance detection chip both adopt VKD233DR type chips.

Further, the force sensor adopts an FT4100 sensor.

The utility model has the advantages that: whether the earphone is worn into the ear or not is detected through the detection of the fact that the second metal film on the ear support enters the ear through a capacitance detection mode, a MCU chip built in the earphone is triggered, the change of the capacity is sensed through the first metal film, the MCU chip built in the earphone is triggered by the change amount, and after the MCU chip is triggered, the MCU chip built in the earphone controls the volume of the mobile phone, the related functions of answering the phone and the like through a Bluetooth unit. The utility model discloses need not directly operate the cell-phone, directly control through the earphone, convenient and fast has increased bluetooth headset's practicality.
