Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The man-machine interaction mode of the TWS earphone is mainly pressing, sliding and knocking. The knocking operation is mainly realized by relying on an accelerometer to detect knocking times, and the pressing and sliding operation is mainly realized by relying on a capacitance sensor to detect conductor contact. In daily use, the conventional pressing, sliding and knocking operations have high false triggering probability, and the user wearing the touch screen generates bad experience and also influences the wearing stability. Based on the above technical problem, the present embodiment provides a TWS headset, which is implemented by referring to fig. 1 specifically, and fig. 1 is a schematic structural diagram of the TWS headset provided in the present embodiment, and the schematic structural diagram specifically includes:
an earplug 100; a stem 200 connected to the earplug; a touch panel 300 is respectively arranged at two sides of the ear handle 200 and used for acquiring touch analog signals; the signal processing device 400 connected to the touch panel 300 is configured to determine whether to generate a trigger signal according to two touch analog signals after receiving the two touch analog signals sent by the two touch panels 300; and the main control chip 500 is connected to the signal processing device 400 and configured to perform a preset operation according to the trigger signal.
It can be understood that, the TWS headset provided in this embodiment may be a left headset or a right headset, and may also be a left headset and a right headset.
The earplug 100 is connected to the ear stem 200 through a connecting portion, which may be a spring, one end of the spring is fixedly connected to the mounting surface of the ear stem 200, and the bottom of the earplug 100 is fixedly connected to the other end of the spring. In this embodiment, the material and physical size of the ear handle 200 are not limited, and the user can customize the setting. The two sides of the ear handle 200 are respectively provided with a touch panel 300, specifically a first touch panel 310 and a second touch panel 320, the touch panels 300 include but are not limited to a capacitive touch panel and a resistive touch panel, and because the touch panel 300 only includes one channel, only a captured touch can be detected, but not a captured slide. Referring to fig. 2, fig. 2 is a front view of a layout of a touch panel 300 of a TWS headset according to an embodiment of the present application; referring to fig. 3, fig. 3 is a left side view of a layout of a touch panel 300 of a TWS headset according to an embodiment of the present application; referring to fig. 4, fig. 4 is a right view of a layout of a Touch Panel 300 of a TWS headset according to an embodiment of the present disclosure, where the Touch Panel 300, i.e., Touch Panel, needs to be laid on two sides of an ear handle 200 of the TWS headset, and under such a layout condition, a user can easily complete normal Touch of the Touch Panel 300 on two sides with two fingers after wearing the Touch Panel normally. Referring to fig. 5, fig. 5 is a schematic diagram of a touch operation of a TWS headset according to an embodiment of the present application, which can ensure that a false triggering rate is greatly reduced, and at the same time, because a user operates with both hands, the position of the headset body can be ensured to be stable, and thus, no adverse effect is generated on wearing.
The touch panel 300 is configured to collect touch analog signals, where the touch analog signals include, but are not limited to, signals corresponding to short press, long press, double press, and the like. Specifically, when there is an effective short press, long press, double click, or the like, the obtained touch analog signal is an effective analog signal, and when there is no effective operation, the obtained touch analog signal is an ineffective analog signal. For an effective touch analog signal, a user can operate the earphone with two fingers, even if the touch pads 300 on two sides of the ear handle 200 are touched at the same time, the whole operation process is stable, and the wearing stability and the user experience of the earphone are not influenced. The problems of wearing instability and mistaken touch caused by pressing on the earphone body are avoided; the problems of high cost and mistaken touch caused by the fact that a plurality of channels are arranged in one direction when the ear handle 200 slides on one side and the operation can be completed only by sequential triggering are solved; the problem of mistaken touch and wearing stability caused by knocking and triggering operations is avoided.
The signal processing device 400 connected to the touch panel is configured to determine whether to generate a trigger signal according to the two touch analog signals after receiving the two touch analog signals sent by the two touch panels 300. Specifically, after the first touch analog signal collected by the first touch panel 310 and the second touch analog signal collected by the second touch panel 320 are received at the same time, the signal processing device 400 determines whether to generate the trigger signal according to the two touch analog signals after receiving the first touch analog signal and the second touch analog signal. It is understood that when the first touch analog signal and the second touch analog signal are simultaneously collected or the collected time interval is within the preset interval range, it is determined that the touch analog signals transmitted by the two touch panels 300 are simultaneously received. Judging whether to generate a trigger signal according to the two touch analog signals, and specifically comprising the following steps: when the first touch analog signal and the second touch analog signal are both effective touch analog signals, generating a trigger signal; when at least one effective touch analog signal exists in the first touch analog signal and the second touch analog signal, no trigger signal is generated, and the touch is determined to be a false touch. Therefore, the touch of the double-side touch pad can be effective, and the probability of false triggering is greatly reduced.
In one implementable implementation, the signal processing device 400 includes: a touch integrated circuit 410 for converting two touch analog signals into high and low level signals; the and circuit 420 is configured to determine whether the high-low level signals corresponding to the two touch panels 300 are both at a high level; and if the voltage is high level, generating a trigger signal.
Referring to fig. 6, fig. 6 is a logic diagram of TWS signal transmission according to an embodiment of the present application. In this embodiment, after the values of the Touch analog signals collected by the left and right Touch panels 300panel1 and panel2 are converted by the Touch integrated circuit 410, i.e., Touch IC, the two signals pass through the and circuit 420, i.e., Gate, and only when the two high and low level signals, i.e., output 1 and output 2, are both high level, the trigger signal, i.e., the high level signal, is output to the main control chip 500. In short, when the left and right touchpads panel1 and panel2 are triggered at the same time (or within a preset time range), the system can regard the occurrence of a user touch event; the detection logic is also used for reducing the false triggering rate and avoiding false triggering when the single side is in contact with the skin.
In an implementation, the touch panel 300300 is configured to determine whether a touch duration of the touch operation is within a preset touch duration range when the touch operation is detected; if the touch duration is within the preset touch duration range, an effective touch analog signal is obtained.
In the embodiment, the preset touch duration range is not limited, and the actual requirements of the user can be limited according to the configuration. For example, if the preset touch duration range is a and the corresponding touch operation is a short press, if the touch analog signal obtained in the preset touch duration range a is an effective analog signal, the corresponding touch integrated circuit 410 converts the obtained high-low level signal into a high-level signal; if the touch analog signal that is not obtained within the preset touch duration range a is an invalid analog signal, the corresponding touch integrated circuit 410 converts the obtained high-low level signal into a low level signal. When the preset touch duration range is b and b > a, and the corresponding touch operation is long press, if the touch analog signal obtained in the preset touch duration range b is an effective analog signal, the corresponding touch integrated circuit 410 converts the obtained high-low level signal into a high-level signal; if the touch analog signal not obtained within the preset touch duration range b is an invalid analog signal, the corresponding touch integrated circuit 410 converts the obtained high-low level signal into a low level signal.
In one implementation, the touch panel 300 is configured to determine whether a touch area of a touch operation is within a preset touch area range when the touch operation is detected; if the touch area is within the preset touch area range, an effective touch analog signal is obtained.
The touch area is not limited in the embodiment, and the user can set the touch area according to actual requirements as long as the purpose of the embodiment can be achieved. For example, if the touch area of the touch operation is within the preset touch area range c, an effective touch analog signal is obtained, and the high-low level signal obtained by the conversion of the corresponding touch integrated circuit 410 is a high-level signal; if the touch area of the touch operation is not within the preset touch area range c, an invalid touch analog signal is obtained, and the corresponding touch integrated circuit 410 converts the obtained high-low level signal into a low level signal.
In an implementation manner, the touch panel 300 is configured to determine whether the number of touches of the touch operation is a preset number of touches when the touch operation is detected; if the touch times are preset, an effective touch simulation signal is obtained.
The number of touches is not limited in this embodiment, and the user may set the number according to actual needs as long as the purpose of this embodiment can be achieved. For example, if the number of touches in the touch operation is within the preset number of touches d, an effective touch analog signal is obtained, and the corresponding touch integrated circuit 410 converts the obtained high-low level signal into a high level signal; if the touch area of the touch operation is not within the preset touch frequency c, an invalid touch analog signal is obtained, and the corresponding touch integrated circuit 410 converts the obtained high-low level signal into a low level signal.
In an implementation manner, the signal processing apparatus 400 is configured to determine whether a time interval between receiving two touch analog signals is within a preset interval, and if so, determine whether to generate a trigger signal according to the touch analog signal.
The preset intervals in the present embodiment include, but are not limited to, 0.5s, 1s, 1.5s, and 2 s. At this time, the embodiment does not limit the touch analog signal, only the existing signal is used as an effective touch analog signal, and as long as the time interval for receiving the two touch analog signals is within the preset interval, the trigger signal is determined to be generated; and if the time interval for receiving the two touch analog signals is not within the preset interval, not generating a trigger signal. In this way, the sensitivity of signal triggering is increased.
In one implementable implementation, touch panel 300 is a capacitive touch panel. The capacitive touch panel only needs to touch, and does not need pressure to generate signals; only one or no correction is needed, while the resistive touch panel requires conventional correction; the service life is long; the system power consumption is superior to that of the resistance touch panel.
In summary, in the present embodiment, by setting the touch pads 300 on both sides, only when both touch pads 300 obtain an effective touch analog signal, the preset operation can be triggered, so that the probability of false triggering of the touch pads 300 can be effectively reduced by the user, and the user experience of the user during the interactive operation can be improved.
Based on the above technical scheme, this embodiment simulates touch trigger signals according to the touch analog signals generated by the simultaneous touch of the double-sided touch panel 300 so as to execute preset operations according to the trigger signals, and simultaneously touches through both sides of the ear handle 200, so that the operation process is stable, the wearing stability is not affected, and only the simultaneous touch is effective, thereby greatly reducing the probability of false triggering and improving the user experience.
