Technical Field

The invention relates to the technical field of intelligent wearable equipment, in particular to a headset.

Background

In recent years, intelligent wearable devices have been developed rapidly, and in particular, headsets represented by VR/AR headsets and noise reduction headsets have a steep trend of increasing types and sales volumes. Along with the function of the headset is more and more, the function modules for realizing the corresponding functions on the headset are more and more, but the whole weight and the size of the headset are required to be light and small, so that the power consumption control is more and more important, because the power consumption control is better, the battery capacity of the headset can be smaller, namely, the size of the battery of the headset can be smaller to meet the light and small requirements. Many functions in the headphone, for example, functions such as physiological parameter collection, audio control just can play a role after the earphone is worn, and after taking off the earphone, if relevant function can suspend automatically, then can reduce the earphone consumption, extension duration to can reduce earphone battery capacity and size, make the whole weight of earphone and size light and exquisite, consequently need detect it when using headphone whether worn.

In the present market, headphone wear the detection mode and usually realize through pressure detection, electric capacity detection or photoelectric detection of ear muff, nevertheless because headphone's ear muff internal surface generally is equipped with cushion, screen cloth and dust keeper etc. pressure, electric capacity and photoelectric detection lead to wearing easily because of the separation that receives cushion, screen cloth and dust keeper etc. and detect inaccurately for headphone's consumption control is poor.

Detailed Description

Exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

As shown in fig. 1, the headphone includes a first side headphone 1, a second side headphone 2 and a headphone cord 3, the first side headphone 1 and the second side headphone 2 are respectively connected to two ends of the headphone cord 3, and the two

side headphones

1 and 2 are electrically connected through the headphone cord 3. Be equipped with signal emission module 4, controller 6 and triaxial acceleration sensor 7 on the earphone 1 of first side, be equipped with signal receiving module 5 on the earphone 2 of second side, controller 6 is electric connection signal emission module 4 and triaxial acceleration sensor 7 respectively to through 3 electric connection signal receiving module 5 of headphone line. The core function of the signal transmitting module 4 is to periodically transmit a wireless data packet (i.e. a wireless signal) with a unique serial number to the signal receiving module 5, wherein the wireless data packet with the unique serial number only functions at the signal receiving module 5; the signal receiving module 5 periodically scans and receives the wireless data packets with the unique serial numbers from the signal transmitting module 4, and calculates the wireless signal strength value according to the number of the wireless data packets. In this embodiment, the signal transmitting module 4 is one of an RF tag, a 2.4G bluetooth transmitting module, or a WIFI transmitting module, the signal receiving module 5 is one of an RF reader, a 2.4G bluetooth receiving module, or a WIFI receiving module, and the signal transmitting module 4 corresponds to the signal receiving module 5, specifically: if the signal transmitting module 4 is an RF tag, the signal receiving module is an RF reader; if the signal transmitting module 4 is a 2.4G Bluetooth transmitting module, the signal receiving module 5 is a 2.4G Bluetooth receiving module; if the signal transmitting module 4 is a WIFI transmitting module, the signal receiving module 5 is a WIFI receiving module.

In this embodiment, the first side earphone 1 of the headset is provided with function modules (not shown), such as a physiological parameter acquisition module and an audio control module, and the controller 6 is electrically connected to the function modules. After the headset is started, the wireless signal sent by the signal sending module 4 is sent to the signal receiving module 5, the signal receiving module 5 generates a wireless signal strength value according to the received wireless signal and then sends the wireless signal strength value to the controller 6, and the controller 6 compares the wireless signal strength value with a preset value; if the user wears the headset, the head of the user is located between the

earphones

1 and 2 on the two sides, the wireless signal strength received by the signal receiving module 5 can be weakened due to the fact that the head of the human body can block the wireless signal, the wireless signal strength value generated by the signal receiving module 5 is lower than the preset value, and then the controller 6 judges that the headset is worn by the user according to the judgment, and controls the function module to work. If the user does not wear the headset, the

earphones

1 and 2 on the two sides are not blocked, the signal sent by the signal sending module 4 is directly sent to the signal receiving module 5, the signal strength received by the signal receiving module 5 cannot be weakened, the wireless signal strength value generated by the signal receiving module 5 cannot be lower than the preset value at the moment, and the controller 6 accordingly judges that the headset is not worn by the user and controls the functional module to be out of work. Therefore, wearing detection of the headset is accurate, the functional module works when the headset is worn, and does not work when the headset is not worn, namely power consumption of the headset is well controlled.

The three-axis acceleration sensor 7 is used for detecting the activity state of the headset, and the three-axis acceleration sensor 7 is an existing conventional device, and the detailed structure and the working principle thereof are not described herein again. After measuring the triaxial acceleration value, the triaxial acceleration sensor 7 transmits the triaxial acceleration value to the controller 6, and the controller 6 combines the triaxial acceleration value and judges whether the triaxial acceleration value exceeds a threshold range, thereby judging the activity state of the current headset. When the controller 6 judges that the headset is not worn, if the three-axis acceleration value exceeds the threshold range, the controller 6 judges that the headset is picked up, so that the signal transmitting module 4 is controlled to enter a high-frequency transmitting mode; if the triaxial acceleration value does not exceed the threshold range within a period of time, the controller 6 judges that the headset is not picked up, and controls the signal transmitting module 4 to enter a low-frequency transmitting mode, so that the power consumption of the system is reduced.

In other embodiments, the controller 6, the three-axis acceleration sensor 7 and the function module may be disposed on the second-side earphone 2, or disposed on the first-side earphone 1 and the second-side earphone 2, which are conventional in the art and will not be described herein.
