Referring to fig. 1, fig. 1 is a flowchart illustrating an implementation of a sound output control method according to an embodiment of the present invention, which is applied to an intelligent bracelet, where the intelligent bracelet includes an earphone and a base for accommodating the earphone, the earphone is internally provided with a control chip and a first speaker, and the base is internally provided with a second speaker.
It is to be noted that, in the embodiments of the present invention, relational terms such as first and second, and the like are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions.
The method comprises the following steps:
S101, judging whether the earphone enters the base or not.
in the embodiment of the invention, whether the earphone enters the base can be determined through data collected by a sensor (such as a Hall sensor and a distance sensor) and a contact point.
That is, determining whether the earphone enters the base, according to different implementation manners, different sensors may be selected or the earphone may be determined whether the earphone enters the base directly in a contact manner, which will be illustrated below as specific how to determine:
The first method is as follows: the distance sensor can be arranged in the side wall of the earphone in the base, and whether the earphone enters the base or not is judged according to the distance length collected by the distance sensor (such as when the earphone enters the base, the distance between the single-side wall and the earphone is collected by the distance sensor, and when the earphone does not enter the base, the distance between the two side walls is collected by the distance sensor).
The second method comprises the following steps: the position of placing the earphone in the base sets up an inspection circuit, places the position at the earphone and sets up a shell fragment or pointer, and after the earphone got into, under the atress effect, shell fragment or pointer deformation switched on inspection circuit.
the third method comprises the following steps: the base sets up hall element, and hall element is connected with control chip electricity, and control chip obtains detecting signal through hall element, judges whether the earphone gets into the base according to detecting signal numerical value. Specifically, the value of the hall voltage collected by the hall element can be compared with a preset hall voltage threshold, when the collected voltage value is greater than the preset hall voltage threshold, the earphone is determined to enter the base, otherwise, the earphone is determined not to enter the base.
of course, in other embodiments of the present invention, reference may also be made to various implementation manners for checking whether the earphone enters the base in the prior art, which are not described in detail herein.
after judging whether the earphone enters the base or not, the earphone can correspond to different sound playing modes according to different judging results.
S102, when the earphone enters the base, the sound channel where the second loudspeaker is located is conducted, the control chip disconnects the sound channel of the first loudspeaker, and sound emission is achieved.
The sound path where the first loudspeaker is located is an earphone circuit, and the sound path where the second loudspeaker is located is a sound external-discharging circuit.

Preferably, in the embodiment of the present invention, in order to automatically turn on or off the relevant sound channel, a controllable switch is further built in the earphone, and the control chip controls the on/off of the controllable switch to turn on/off the sound channel where the first speaker is located. Specifically, when the earphone enters the base, the control chip can control the on-off state (i.e., on or off) of the controllable switch, so as to control the on-off state of the sound path where the first speaker is located.
wherein, the earphone gets into the base then switches on sound discharge circuit, and its specific implementation can specifically be: a first conductive element is arranged on the back of the earphone and electrically connected with the control chip, and a second conductive element is arranged outside the base;

Specifically, when the earphone enters the base, the sound channel where the second loudspeaker is located is conducted, and meanwhile the control chip disconnects the sound channel of the first loudspeaker, so that sound can be played out, namely, the smart band directly plays sound out by using the second loudspeaker in the base; when the earphone does not enter the base, the sound path where the second loudspeaker is located is disconnected, the control chip switches on the sound path of the first loudspeaker, and the sound playing of the first loudspeaker can be realized, namely, the sound is played through the earphone. Therefore, the user can take out the earphones or place the earphones from the inside of the intelligent bracelet according to the requirements of the user, and the sound output mode can be freely switched.
Example two:
Referring to fig. 2, fig. 2 is a specific flowchart of a sound output control method according to an embodiment of the present invention, which is applied to an intelligent bracelet, where the intelligent bracelet includes an earphone and a base for accommodating the earphone, the earphone is internally provided with a control chip and a first speaker, and the base is internally provided with a second speaker. The following describes the method in detail in the case that the headset is specifically a wireless headset, and the method includes the following steps:
S201, detecting the voltage of the Hall device embedded in the built-in cavity wall of the wireless earphone.
Among them, a hall device, i.e., a device capable of generating a hall effect. Hall effect: when a control current is conducted to two ends of the semiconductor slice and a magnetic field is applied to the vertical direction of the slice, a potential difference is generated in the direction vertical to the current and the magnetic field, and the potential difference is a Hall voltage.
In the embodiment of the invention, the hall device can be a hall element made of a semiconductor material, and can also be a hall chip (the same hall sensor) obtained by integrating the hall element with an amplifier circuit, a temperature compensation circuit, a voltage-stabilized power supply circuit and the like.
To realize sound production, a horn mainly uses a transduction principle (Transducer), including: moving coil type, iso-magnetic type, electrostatic type, electret type, moving iron type. The transduction principles commonly used at present are mainly two main categories of moving coil (Dynamic) and Electrostatic (Electrostatic) earphones. Wherein, the moving coil earphone principle: at present, most (more than 99 percent) earphone earplugs belong to the same type, the principle is similar to that of a common sound box, a coil in a permanent magnetic field is connected with a vibrating diaphragm, and the coil drives the vibrating diaphragm to sound under the drive of signal current. An electrostatic earphone: the vibrating diaphragm is in a changing electric field, the vibrating diaphragm is extremely thin and accurate to a few microns (the vibrating diaphragm of the static earphone of the new generation of the current STAX is accurate to 1.35 microns), and the coil drives the vibrating diaphragm to sound under the driving of the electric field force. It can be seen that the earphone contains a magnet in order to realize sound production, and a magnetic field is arranged around the magnet. Therefore, when the earphone is close to the hall device, a hall voltage will be generated under the principle of the hall effect.
In the embodiment of the invention, the smart bracelet is a bracelet capable of being internally provided with a wireless earphone, specifically, a cavity is arranged on a base of the smart bracelet, the structural shape of the cavity can be set according to the shape structure of the wireless earphone, and a hall device can be embedded in the wall of the cavity arranged in the wireless earphone in order to detect whether the wireless earphone is moved out of the smart bracelet.
S202, judging whether Hall voltage appears.
When the wireless earphone is arranged in the cavity wall, the Hall device generates Hall voltage under the action of a magnetic field of a magnet in the wireless earphone, and after the wireless earphone is moved out of the intelligent bracelet, the Hall device does not have Hall effect.
Specifically, judge whether hall voltage appears, its specific judgement includes:
Judging whether the Hall effect voltage corresponding to the Hall device is zero or not;
step two, if yes, determining that no Hall voltage exists;
And step three, if not, determining that the Hall voltage appears.
For convenience of description, the above three steps will be described in combination.
The Hall effect voltage is a potential difference generated in a direction perpendicular to the current and the magnetic field.
When the Hall effect voltage is zero, the situation that no magnetic field exists in the direction perpendicular to the current is indicated, namely the wireless earphone is not arranged inside the intelligent bracelet; when the Hall effect voltage is nonzero, it indicates that a magnetic field exists in the direction perpendicular to the current, namely the wireless earphone is inside the intelligent bracelet.
After determining whether the hall voltage exists, determining a sound playing mode according to a judgment result, specifically, if so, executing step S203; if not, step S204 is performed.
s203, the earphone circuit inside the intelligent bracelet is connected, and the sound discharge circuit inside the intelligent bracelet is disconnected, so that the wireless earphone is used for sounding.
and the earphone circuit is communicated, namely, the earphone circuit is enabled to enter an operating state, so that the wireless earphone is used for converting the sound signal into sound.
Specifically, on-off control of the earphone circuit and the sound amplification circuit can be realized by controlling controllable switches in the earphone circuit and the sound amplification circuit. I.e. the controllable switch of the earphone circuit can be closed and the controllable switch in the sound discharging circuit can be opened. At this time, the user can make and receive calls, listen to music, etc. through the wireless headset.
And S204, connecting the sound external-discharging circuit and disconnecting the earphone circuit so as to sound by using a loudspeaker in the sound external-discharging circuit.
I.e. the controllable switch of the earphone circuit can be opened and the controllable switch in the sound discharging circuit can be closed. At the moment, the user can directly answer the call, listen to music and the like in a mode of playing sound outside the bracelet.
In order to facilitate better understanding of the above steps S201 to S204 for those skilled in the art, the following describes the above steps S201 to S204 in combination with a specific schematic circuit diagram and a schematic control flow diagram as an example.
Referring to fig. 3, fig. 3 is a schematic diagram of an earphone circuit according to an embodiment of the present invention.
In fig. 3, hall is a hall device, and the hall device is connected with the MCU through an I2C bus. The MCU (Micro Control Unit, also called Single Chip Microcomputer (MCU)) or a Single Chip Microcomputer (MCU) integrates a CPU, an RAM, a ROM, a timing counter, and various I/O interfaces of a computer on one Chip to form a Chip-level computer. The SPK is a loudspeaker, the MCU controllable switch is a switch device which can be controlled by the MCU to be switched on and off, and the switching on and off of the earphone circuit and the external discharge circuit are determined by controlling the on and off of the MCU controllable switch.
When wireless earphone took out, the sound broadcast was normal earphone mode, and MCU returns the detected value 0 through hall (through taking out and putting into of hall detection wireless earphone), detected that the earphone breaks away from the wrist strap base, and the switch closure on the SPK circuit through MCU control earphone simultaneously makes earphone SPK switch on, realizes normal earphone mode.
When the wrist strap base was put back to the earphone in, MCU was 0 through hall return value, detected the earphone and put into the base, this moment, the switch disconnection in MCU control earphone SPK circuit, and the earphone is put into the base this moment, and the SPK shell fragment in with the base effectively contacts and switches on, and outside SPK (loudspeaker in the circuit of putting outward promptly) just has accessed into the circuit like this, can realize that sound is put outward.

The Hall device can generate Hall voltage under the action of a magnetic field. The earphone has a magnet inside, and a magnetic field exists around the magnet. Therefore, the embedding need not the hall device in the intelligent cavity wall of crisis, and after the wireless earphone was put back intelligent bracelet base, can produce hall voltage because of the existence of the magnetic field around the magnet of wireless earphone, and after the wireless earphone was taken off, then can also no longer exist because of disappearance of magnetic field, hall voltage. Based on this, in the method, the output mode of the current sound can be determined by monitoring the Hall device and determining whether the Hall voltage appears. Specifically, when the wireless earphone is stored in the intelligent bracelet base, the Hall voltage exists at the moment, the wireless earphone can be communicated with the sound external-playing circuit and sounds through the loudspeaker, namely, an external-playing mode; after the wireless earphone is taken out, no Hall voltage exists at the moment, the circuit of the earphone can be communicated, and the earphone can sound through the earphone, namely, in an earphone mode.
