Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
The principle of the invention is as follows: a sleep state monitoring unit is added in the headset, whether a user enters a sleep state or not is detected through the sleep state monitoring unit, and whether the sleep state is a light sleep state or a deep sleep state is judged. When the user is judged to start to enter the light sleep state, the output volume of the loudspeaker is controlled to be reduced, and the rotating speed of the vibration motor is controlled to be reduced. When the user is judged to enter the deep sleep state, the ear muff distance expansion unit is controlled to work, so that the indirect increase among the ear muffs of the headset is realized, and the headset is separated from the ears of the user.
Fig. 1 is a schematic structural diagram of a headphone according to an embodiment of the present invention, and as shown in fig. 1, the headphone includes a left ear muff, a right ear muff, a headband portion connecting the left ear muff and the right ear muff, two speakers 105 respectively disposed in the left ear muff and the right ear muff, a vibration motor 104, a sleep state monitoring unit 102, a control unit 101, and an ear muff distance expansion unit 106.
The sleep state monitoring unit 102 is configured to monitor different sleep states of the headset user and send the monitoring result to the control unit 101.
And the control unit 101 is used for controlling the output volume of the loudspeaker 105 to be reduced when the monitoring result of the sleep state monitoring unit 102 is light sleep. When the monitoring result of the sleep state monitoring unit 102 is a deep sleep, a distance increasing signal is sent to the ear muff distance expansion unit 106.
And an ear muff distance expansion unit 106, configured to increase the distance between the left and right ear muffs after receiving the distance increase signal sent by the control unit 101, so that the headset is separated from the ears of the user.
Fig. 2 is a schematic diagram of a headset in an embodiment of the invention; referring to fig. 2, in the present embodiment, the sleep state monitoring unit is a brain wave sensor 202.
The brain wave sensor 202 is provided in a headband portion of the headset, and monitors brain waves of a user of the headset, and transmits a signal to the control unit after detecting the brain waves of the user in a light sleep or deep sleep state. Because the brain is in the light sleep state and the deep sleep state, the frequency of the brain waves is different. Wherein, in a light sleep state, the brain wave is theta wave, and the frequency is 4-8 Hz; in the deep sleep state, the brain wave is a wave with a frequency of 0.5-4 Hz.
In a preferred embodiment of the present invention, the brain wave sensor 202 may monitor the brain wave frequency of the user, and then send the monitored brain wave frequency to the control unit 101. Or, after detecting the brain waves of the user in the shallow sleep state, the brain wave sensor 202 monitors the θ brain waves and sends a first signal to the control unit; after detecting the brain waves of the user in the deep sleep state, namely monitoring the brain waves, a second signal is sent to the control unit.
The control unit 101 performs corresponding control according to the brain wave frequency transmitted from the brain wave sensor 202. The method specifically comprises the following steps: the control unit 101 is used for controlling the output volume of the loudspeaker 105 to be reduced when detecting the first signal sent by the brain wave sensor 202; that is, it can be determined that the user is in the light sleep state based on the received first signal. For transmitting a distance increasing signal to the ear muff distance expansion and contraction unit 106 when the second signal transmitted from the brain wave sensor 202 is detected; that is, it can be determined that the user is in the deep sleep state according to the received second signal.
In the present embodiment, the brain wave sensor 202 is adopted as the sleep state monitoring unit 102, which has the following advantages: the brain wave sensor 202 can accurately determine whether the user is in a shallow sleep or a deep sleep in the current sleep state. An additional unit for assisting the judgment of the sleep state is not needed.
Fig. 3 is a schematic view of a headphone according to another embodiment of the present invention; as shown in fig. 3, in the present embodiment, the sleep state monitoring unit 102 does not employ the brain wave sensor 202, which is relatively expensive, but employs the acceleration sensor 302, which is relatively inexpensive.
Because in the light sleep state, the user's body position changes less and after entering the deep sleep state, the user's body position does not change substantially. When the body position of the user changes, the headset can be driven to displace, and the acceleration sensor can detect the movement of the headset. Therefore, in a period of time, the acceleration sensor does not detect the change of the body position of the user, and can judge that the user is in a light sleep state, and if in a later period of time, the acceleration sensor does not detect the change of the body position of the user, and can judge that the user is in a deep sleep state.
In one embodiment of the present invention, the acceleration sensor 302 is disposed at the headband portion or the left and right ear cups of the headset, and is used for detecting the displacement change of the headset and sending a signal to the control unit after detecting the displacement of the headset. That is, the acceleration sensor 302 sends a signal to the control unit 101 whenever the body position of the user changes.
And the control unit 101 is used for controlling the output volume of the loudspeaker 105 to be reduced when the signal sent by the acceleration sensor 302 is not detected in the time period T1. That is, the user's posture does not change within a certain time range, and the user is considered to be in a light sleep state. For sending a spacing increase signal to the ear muff spacing expansion unit 106 when the signal sent from the acceleration sensor 302 is not detected within a period of T2 after T1. That is, a change in the posture of the user is not detected for a while after the user enters the light sleep, and the user is considered to be in the deep sleep state.
In the practical use process of the invention, when a user of the headset is asleep, the user may inevitably turn over or take other sudden actions, and the acceleration sensor 102 may detect the actions and send signals to the control unit 101, so that the control unit 101 may misjudge that the user does not enter the sleep state. Therefore, in an embodiment of the present invention, in order to avoid the interference of the user turning over during sleep or the like to the determination of the sleep state of the user, preferably, the control unit 101 is further configured to filter out the signals transmitted by the acceleration sensor 102 with the duration less than the specified value during the time periods T1 and T2. Wherein, the designated value can be set according to the actual situation. In a specific embodiment of the invention, the control unit 101 filters out the signals sent by the acceleration sensor 102 with a duration less than 3s by means of a specific algorithm.
In order to better judge whether the user is in the sleep state currently, the headset further comprises: a microphone 109 and a sound processing unit 108. The microphone 109 is configured to collect an external sound signal and send the collected sound signal to the sound processing unit 108. And the sound processing unit 108 is used for filtering and amplifying the collected sound signals and then sending the sound signals to the control unit 101. The control unit 101 controls the output volume of the speaker 105 or sends a distance increasing signal to the ear muff distance expansion unit 106 according to the processed sound signal. Specifically, the control unit 101 determines whether the user enters a sleep state according to the processed sound signal, and controls the output volume of the speaker 105 to decrease or sends a distance increasing signal to the ear muff distance expansion unit 106 if the user enters the sleep state. If the sleep state is not entered, the output volume of the loudspeaker 105 is controlled to be restored or not processed. That is, the microphone 109 and the sound processing unit 108 can send signals to the control unit when determining that the user does not enter the sleep state or wakes up from the sleep state, so as to interrupt the original step of controlling the output volume reduction of the loudspeaker 105 by the control unit 101 or sending a distance increasing signal to the ear muff distance expansion unit 106, so that the headset can resume normal operation. And in the case where it is judged that the user is still in the sleep state, no signal is transmitted, and the control unit 101 continues the previous operation.
In this embodiment, one or more microphones form a microphone module to collect external sounds, such as speaking sounds of a user or breathing sounds. After being filtered and amplified by the sound processing unit 108. The control module 101 assists to determine whether the user really enters the sleep state according to the processed sound signal. Specifically, the control unit 101 identifies the processed sound signal sent by the sound processing unit; if the sound signal is recognized as a voice signal, the output volume of the speaker 105 is controlled to be restored. Wherein, because it is detected that the user is speaking, the user is not in the sleep state at present, and the output volume of the loudspeaker 105 is controlled to be restored; otherwise, if the user is in the sleep state according to the judgment of the acceleration sensor 102, the control is performed according to the timer and the signal sent by the acceleration sensor 102. I.e. to control the output volume of the loudspeaker 105 to decrease or to send a pitch increase signal to the ear cup pitch stretching unit 106.
The ear cup distance expansion unit 106 starts to operate after receiving the distance increase signal transmitted from the control unit 101, so that the distance between the left and right ear cups of the headphone is increased, and the headphone is easily detached from the ear of the user. The structure of the ear muff distance expansion unit 106 is not limited to one, as long as the effect of increasing the distance between the left and right ear muffs of the headset can be achieved.

In one embodiment of the invention, the specified value of the pulling force is 500 newtons, and when the stress sensor 107 senses that the pulling force of the control line 404 reaches 500 newtons, a feedback signal is sent to the control unit 101. The control unit 101 stops the rotation of the vibration motor 104 according to the feedback signal and locks the vibration motor 104 so that the distance between the two ear cups of the headphone is maintained.
