Referring to fig. 1, the headphone sound cavity pressure equalizing system of the present invention comprises: the detection unit 11, the control unit 12 and the pressure equalizing air valve 13 controlled by the control unit; wherein, the pressure equalizing air valve 13 is arranged between the front acoustic cavity and the rear acoustic cavity of the headset;
a detection unit 11, configured to detect whether the headset is worn, obtain a detection signal, and send the detection signal to the control unit 12;
the control unit 12 is used for receiving the detection signal sent by the detection unit and controlling the pressure equalizing air valve to be opened or closed according to the detection signal;
and the pressure equalizing air valve 13 is used for being opened or closed under the control of the control unit and can be communicated with the front sound cavity and the rear sound cavity when being opened.
Fig. 2 is a schematic diagram of a pressure equalizing system for an acoustic cavity of a headphone according to an embodiment of the present invention. Referring to fig. 2, the voltage equalizing system of the headphone of the present invention specifically realizes the principle that: a pressure equalizing air valve 13 and a detection unit 11 are respectively arranged between the front acoustic cavity and the rear acoustic cavity of the left ear cup and the right ear cup of the headset. Firstly, the detection unit 11 detects whether the headset is worn (namely, worn on the head of a user), and when the detection unit 11 detects that the headset is not worn, the detection information is sent to the control unit; after receiving the detection information, the control unit 12 controls the pressure equalizing air valve 13 to open, so that the front acoustic cavity space and the rear acoustic cavity space of the headset are kept in a communicated state, and the air pressure balance of the front acoustic cavity and the rear acoustic cavity of the headset is realized.
It is understood that the detecting unit 11 is disposed in the left and right ear cups of the headset in this embodiment, and in other embodiments of the present invention, the detecting unit may be disposed in any position of the headset where it can sense whether the user wears the status information, for example, the position may be the headband of the headset. At this time, detection is performed by the detection unit 11 provided on the headband of the headphone to obtain a detection signal.
When the detection unit 11 detects that the headset is worn on the head of the user, the detection information is also sent to the control unit 12; the control unit 12 controls the pressure equalizing valve 13 to close according to the detection information.
In the present embodiment, the detection unit 11 is a capacitive sensor, a photoelectric sensor, an infrared sensor, or a pressure sensor.
In the present embodiment, the control unit 12 is configured to control the pressure equalizing air valve 13 to be in an open state when the detection signal indicates that the headphone is not worn; or the control unit 12 is used for controlling the pressure equalizing air valve 13 to be closed after the detection signal indicates that the headset is worn and delaying for a preset time period.
Specifically, the preset time period is 1 second or 2 seconds, and in the time period, because the pressure equalizing air valve is in an open state, the front and back sound cavity spaces of the headset are in a completely communicated state, so that when the headset is worn, sudden air pressure in the sound cavity caused by the clamping force of the headset can be instantaneously balanced between the front and back sound cavities. It should be noted that the preset time of delay of 1 second or 2 seconds in this embodiment is an exemplary description, and in practical application, the time of air pressure equalization should be determined according to a specific example, so that it can be seen that the pressure equalization system provided by the present disclosure can achieve the purpose of air pressure equalization within the moment when the air pressure valve is opened. After the air pressure in the ear cavity of the headphone is balanced, the control unit 12 controls the pressure equalizing air valve 13 to be closed, so that the automatic pressure equalization of the sound cavity of the headphone is realized when the user wears the headphone next time.
In this embodiment, further, between the detection unit 11 and the control unit 12, the system further includes: a signal processing unit 200;
the signal processing unit 200 is configured to amplify, filter, and convert the detection signal before the detection unit 11 sends the detection signal to the control unit 12, and send the processed signal to the control unit 12.
Since the detection signal obtained by the detection unit 11 may be a weak signal or an interference signal, in order to ensure that the receiving end (the control unit 12) can successfully receive a correct signal, the system further includes a signal processing unit 200, which preprocesses the signal detected by the detection unit, in this embodiment, the detection unit 11 may be a capacitive sensor, a photoelectric sensor, or an infrared sensor, when the detection unit is a capacitive sensor, the capacitance of the sensor causes a transformation, so that the user's head can be accurately detected, and after the signal processing unit 200 receives the signal of the sensor, the signal processing unit performs a preliminary amplification, filtering signal conversion, and other processes, so as to convert the signal into a signal that the control unit can receive the processes. Similarly, when the detection unit 11 employs a photoelectric sensor, it is detected whether the user has worn the head of the user accurately by a change in light propagation, and the signal processing unit 200 performs a preliminary process after receiving a signal from the sensor. Similarly, when the detecting unit 11 employs an infrared sensor, according to the principle of infrared reflection, when a certain part of the body of the user is in the infrared region, the infrared rays emitted by the infrared emitting tube are reflected to the infrared receiving tube due to the shielding of the head of the user, and then the information whether the headphone is worn is accurately determined. Similarly, when the detecting unit 11 is a pressure sensor, it is detected whether the earphone is worn on the head of the user by detecting the pressure change received at the ear cup, and the signal processing unit 200 receives the signal of the sensor and then performs a preliminary process.
It can be understood that the embodiment of the present invention is not limited to the four types of sensors mentioned above, and in other embodiments, other sensing devices can be used as the detection unit to complete the function of detecting whether the headphone is worn to obtain the detection signal.
In this embodiment, the control unit 12 is further configured to notify the audio output port to start playing audio when the pressure equalizing air valve 13 is controlled to be closed.
Specifically, the control unit 12 notifies the audio output port of the audio output device connected to the headphone to start playing the audio information while controlling the pressure equalizing air valve 13 to open, thereby achieving air pressure balance between the front and rear sound cavity spaces of the headphone. Thus, after the control unit 12 judges that the earphone is worn on the head of the user, the pressure equalizing air valve 13 is controlled to be closed and the user starts to listen to music, and the original state of the acoustic system is recovered, so that the pressure equalizing system has no influence on the sound quality of the earphone.

When a user just wears the earphone and does not listen to music, the front sound cavity 404 and the rear sound cavity 406 of the headset are isolated by the closed pressure equalizing air valve, air flow generated by wearing the headset meets great resistance in the advancing process, great air pressure difference can be generated, pressure equalizing is needed at the moment, the control unit can send out an instruction for opening the pressure equalizing air valve according to the change of the wearing state of the headset detected by the detection unit, after the pressure equalizing air valve receives the opening instruction of the control unit, the pressure equalizing air valve is in the opening state 401 to open the pressure equalizing hole 402, therefore, sufficient and completely communicated space is formed between the front sound cavity 404 and the rear sound cavity 406, and the flow guide between the spaces of the front sound cavity 404 and the rear sound cavity 406 can be ensured to be conducted through the opened pressure equalizing hole in the advancing air flow moment (within a time period of 1 second or 2 seconds or shorter), so as to realize pressure equalizing. The technical problems that the air pressure which changes sharply between the front and the rear sound cavities directly acts on the vibrating diaphragm of the earphone loudspeaker to generate 'click' eardrum deformation noise and the vibrating diaphragm is seriously or even directly damaged are solved. Then, after a certain delay time for realizing the pressure equalization, the audio needs to be played normally, so the control unit will send out an instruction again after delaying the preset time period, control the pressure equalization air valve to close, thereby close the pressure equalization hole, isolate the front sound cavity and the rear sound cavity, recover the original state of the acoustic system (please refer to fig. 3 a), and inform the audio output port to start playing the audio, and ensure the audio quality of the played audio.

The shape of the pressure equalizing holes in this embodiment approximates to a vertically placed rectangle. It is understood that the shape of the pressure equalizing hole is not limited to the specific shape in the present embodiment, and other shapes of pressure equalizing holes may be used, for example, a honeycomb-shaped pressure equalizing hole formed by a plurality of small holes with smaller diameters, as long as the pressure equalizing hole can ensure that the air pressure between the front and rear sound cavity spaces reaches the purpose of instantaneous equalization when the pressure equalizing valve is in the closed state.
