Fig. 1 shows a block diagram of a distress device 100 according to an exemplary embodiment of the present application.

As shown in fig. 1, the distress apparatus 100 includes a housing 107, a sound generating assembly 103, and a control device 104, and the control device 104 includes a control part 104 a.

The housing 107 is used to enclose the sound emitting assembly 103 and the like.

Fig. 5 is an embodiment of the housing 107. As shown in fig. 5, the housing 107 is generally spherical, but in other embodiments, other shapes may be used, such as cylindrical, ellipsoidal, mostly spherical/ellipsoidal, etc., with a small portion being a flat surface or a curved surface (e.g., a curved surface with a larger radius), etc. The housing 107 is comprised of two hemispherical shells, an upper shell 1071 and a lower shell 1072. The upper and lower housings 1071 and 1072 may be removably coupled (e.g., threaded, screwed, snap-fit, etc.) or non-removably coupled (e.g., glued, riveted, welded, snap-fit, etc.). When connected in an undetachable manner, it may increase the difficulty of gangsters damaging the distress apparatus 100.

The sound generating assembly 103 and other components may be integrated on a circuit board, and the housing 107 may include a structure for receiving and fixing the circuit board therein.

In some embodiments, the housing 107 further includes structure for engaging the control device 104, such as a notch 1073, the notch 1073 allowing a user to operate the control element 104 a. For example, the control component 104a may be extended into the distress apparatus 100 from the indentation 1073, mated with other components of the control device 104, or removed from the indentation. The housing 107 may also include other structures that cooperate with the control device 104, such as structures that removably secure the control component 104a to the housing 107 (e.g., removable snap structures, etc.), such that the control component 104a is not separated from the housing 107 due to gravity or shaking, etc.

In some embodiments, the housing 107 also includes a sound outlet 1074.

In some embodiments, the user may throw the distress device 100 out when a distress is required, requiring the offender to simultaneously subdue the user, stopping the distress device 100 from sounding a distress sound. When the user throws it out, the person is separated from the distress device, making it difficult for the offender to accomplish both goals simultaneously, increasing time consumption if at all. When the user throws the distress apparatus 100 far away or into a crow, it may be difficult for the offender to find the distress apparatus 100, thereby being able to always ask for help for the user.

In some embodiments, the housing 107 has a structure that facilitates movement over the ground, such that the distress device 100 can more easily be moved further after being thrown, increasing the difficulty for an adversary to find the distress device. For example, the housing 107 may be entirely or mostly spherical, ellipsoidal, cylindrical, rectangular or square with rounded corners, etc. Of course, these shapes have other advantages, such as easy holding by the user, and the spherical and ellipsoidal shapes are not easily damaged by ruffian.

In some embodiments, the housing 107 further includes a structure for connecting to other objects, such as a connecting ring, so that the distress device 100 can be hung on an object such as a piece of clothing, a backpack, a key ring, etc.; or the housing 107 may include a flat surface for attachment to a mobile phone or the like so that the distress apparatus 100 may be attached to the mobile phone or the like. Therefore, people can carry the help-seeking device 100 around at any time and can trigger the help-seeking function at the first time when encountering danger.

In some embodiments, the housing 107 is made of a hard material (rigid material), such as plastic, glass, metal, etc., that is resistant to damage. When the housing 107 is hard, the distress apparatus 100 can be prevented from being damaged by the offender, and therefore, even if the offender finds the distress apparatus 100, the offender cannot stop it from making a distress sound by damaging it.

In some embodiments, the housing 107 is made of a material having elasticity such that the distress device 100 can be bounced farther away when ejected.

In some embodiments, the housing 107 comprises two layers, an outer layer made of a material having elasticity and an inner layer made of a hard material, so that it can be moved farther away when being ejected, and can be prevented from being damaged.

In some embodiments, the housing 107 further includes user information of the user, wherein the user information includes all or part of personal information of the user, emergency contact information, and identification information having a one-to-one correspondence with the user.

In some embodiments, the identification information having a one-to-one correspondence relationship with the user is an equipment identification of the distress apparatus 100. The device identifier has uniqueness, that is, one device identifier corresponds to only one distress device 100, the user can send the device identifier and the personal information to the server after purchasing, the server establishes a corresponding relationship between the device identifier and the personal information, or a manufacturer acquires the personal information of the user when selling the device identifier and the personal information, and establishes a corresponding relationship between the device identifier and the personal information.

In some embodiments, the identification information having a one-to-one correspondence with the user is identification information assigned by the server to the user when the user registers, identification information assigned to the user when the user purchases, and the like.

In some embodiments, the server stores a corresponding relationship between the user and the identification information, so that the identification information can be uploaded to the server after the enthusiastic masses pick up the distress device 100, and the server determines the corresponding user according to the identification information and sends a distress message to the user.

In some embodiments, the user information may be printed/pasted on the housing 107 in the form of text, bar code, two-dimensional code, or the like. When the identification information is information such as identification information of the user, the information may be obtained from the user after the user places a purchase order, and the identification information may be placed on the housing 107.

In some embodiments, a writing or pasting area is also included on the housing 107 so that the user can write or paste his or her own user information on the housing 107.

When the housing 107 contains the identification information, after hearing a distress sound emitted by a certain distress device 100, others can find the distress device 100 and check the identification information thereof, and then give an alarm or ask for help for others through the identification information, if the identification information is provided for the police during alarming, the police can obtain corresponding personal information according to the identification information; the identification information is provided for the server through mobile phone app and the like, so that the server confirms the corresponding help-seeking user according to the corresponding relation between the identification information and the personal information, and gives an alarm to the help-seeking user or sends a help-seeking message to an emergency contact of the help-seeking user. Therefore, even if no people can ask for help around the distress device in distress, the distress call device 100 can continuously call for help, and people can obtain information of the people in distress as long as people look at the distress call device 100, so that the people in distress can be alarmed or asked for help.

In some embodiments, the control device 104 includes a control component 104a, the control component 104a being at least partially external to the housing 107, the control component 104a being completely separable from the housing 107 and other components of the control device 104; when the control part 104a is in a preset position, the sound production assembly 103 does not produce the distress sound; when the control part 104a is not at the predetermined position (e.g., when the control part 104a is separated from the housing 107 and other parts of the control device 104), the sound generating assembly 103 generates a distress sound. Therefore, when the user needs to ask for help, the user can send out the help by separating the control part 104a from other parts (the housing 107 and other parts wrapped by the housing) of the help asking device 100.

In some embodiments, all of the components of the control device 104 other than the control component 104a are secured within the housing 107; alternatively, the control device 104 may be located at least partially on the housing 107 or outside the housing 107, such as two connecting members extending from the housing 107, except for the control part 104 a. Therefore, the control part 104a is attached to a certain position of the housing 107, or one end of the control part extends into a notch of the housing, so that the control part 104a is matched with other parts of the control device 104 at a preset position, and the sound generating assembly 103 does not generate the distress sound.

In some embodiments, the control device 104 is a switch that includes a control component 104 a; when the control part 104a is in a predetermined position, the switch is in an open or closed state; when the control part 104a leaves the predetermined position, the switch is in a closed or open state. The distress device 100 may be different according to different embodiments, and is not limited herein, and only needs to make the control part 104a not send out a distress sound when the control part is in a predetermined position; when the mobile phone is not in the preset position, the mobile phone can send out the distress sound.

In some embodiments, the control device 104 is a switch composed of two connecting parts and a control part, the control part controls the two connecting parts to be in contact with or to be out of contact with each other, the contact or the disconnection of the two connecting parts corresponds to the switch being turned on or off, and the distress device 100 determines whether to make the sound generating assembly 103 generate a distress sound according to the switching of the switch.

In one embodiment, the control member 104a brings the two connection members into contact when approaching them, and the control member 104a disconnects the two connection members when moving away from them. For example, the control member 104a has magnetism, and one of the two connection members is a deformable thin plate made of a metal material, which is brought close to the control member by the magnetic force of the control member 104a, and is restored to an original position when the magnetic force is small/vanished, and the thin plate is in two positions such that the thin plate is kept in contact with or out of contact with the other of the two connection members.

Fig. 2 is a schematic diagram of this embodiment, the switch is composed of a control component 104a, a connecting component 104b and a connecting component 104c, the whole of the control component 104a or a part close to the connecting component 104b has magnetism, one end of the connecting component 104b is fixed, and the other end is not fixed; the connecting member 104c is fixed at both ends or otherwise not biased from its position by magnetic force; when the magnetic force is not acted, the connecting part 104b is contacted with the connecting part 104c, and the switch is closed; when acted upon by the magnetic force, the movable side of the attachment member can be deflected from its initial position to break contact with the attachment member 104c, causing the switch to open.

It will be appreciated that other alternatives are possible, for example, the control part 104a disconnecting two connecting parts when it is close to them and the control part 104a contacting them when it is far from them. Illustratively, the movable contact element is disconnected from the fixed contact element when not subjected to the magnetic force and is contacted with the fixed contact element when subjected to the magnetic force.

In another embodiment, the control member 104a disconnects the two connecting members when it is between them, and allows contact between the two connecting members when the control member 104a is removed from between them. For example, one or both of the two connection members may be a deformable sheet made of a metal material, the two connection members may be disposed opposite to each other, the control member may be made of an insulating material, and the control member 104a may be inserted into or removed from between the two connection members so that the two connection members are disconnected from or kept in contact with each other.

Fig. 3 is a schematic view of this embodiment, the control part 104a is a pin, and all or a portion of the control part 104a contacting both the connection parts is made of an insulating material. The two connecting members are a fixed portion 104d and an elastic portion 104e, respectively, the fixed portion 104d is fixed and immovable, the elastic portion 104e has one end fixed and the other end not fixed, and the elastic portion 104e is made of a material having elasticity so that it can be deformed, such as a metal sheet. When one end of the control component 104a is inserted between the fixed part 104d and the elastic part 104e, the fixed part 104d and the elastic part 104e are not contacted, and the switch is turned on; when the control component 104a is moved out from between the fixed part 104d and the elastic part 104e, the elastic part 104e moves towards the fixed part 104d under the action of the elastic force of the elastic part, so that the fixed part 104d is contacted with the elastic part 104e, and the switch is closed. In other embodiments, both of the connecting members are elastic portions 104 e.

It will be appreciated that other alternatives are possible, such as the control member 104a contacting the two connecting members when it is between them and the control member 104a breaking the two connecting members when it is removed from between them. For example, one or both of the two connecting members are deformable sheets made of a metal material, and the two connecting members are arranged oppositely and have a certain gap; the control part 104a is made of a conductive material; when the control part is inserted between the two connecting parts, the control part fills the gap between the two connecting parts, so that the two connecting parts are indirectly contacted (conducted) through the control part; when the control member is removed from between the two connection members, the two connection members are disconnected (non-conductive) due to the gap.

It will be appreciated that the above embodiments of the switch are merely exemplary and that other forms of switches may be employed.

In some embodiments, the control device 104a includes a control component 104a and a sensing device 104 f; the sensing device 104f determines the position of the control part 104a, and when the control part 104a is at a predetermined position, the sensing device 104f outputs one signal, and when the control part 104a is not at the predetermined position, the sensing device outputs the other signal; the processor 101 determines whether to make the sound generating assembly 103 generate a distress sound according to the signal output by the sensing device 104f (for example, the processor 101 may be connected to the output interface of the sensing device 104f at the input port, so that the processor 101 can obtain the signal output by the sensing device 104f from the input port; the output interface of the sensing device 104f may also be connected to an external interrupt interface of the processor 101, and the sensing device 104f outputs an interrupt signal when the control component 104a is not in the predetermined position). Illustratively, the housing 107 includes a notch extending inward, and the end of the notch is fixed with a sensing device 104f, and when one end of the control part 104a passes through the notch and approaches or contacts the sensing device 104f, the sensing device 104f outputs a signal; when the control part 104a is removed from the notch, the sensing device 104f outputs another signal. Fig. 4 is an example of this embodiment.

In some embodiments, the sensing device is a distance sensor. The distance sensor can be classified into an optical distance sensor, an infrared distance sensor, an ultrasonic distance sensor and the like according to different working principles. When the control part 104a is close to the sensing device 104f, the distance sensor outputs a signal; the distance sensor outputs a signal when the control component 104a is at a distance from the sensing device 104f or when the control component 104a is completely separated from the other components of the distress apparatus 100. The processor 101 determines whether the control part 104a is in a predetermined position according to the signal output by the sensing device 104f, and further determines whether to make the sound generating assembly 103 generate the distress sound.

In some embodiments, the sensing device 104f is a hall sensor and the control component 104a is magnetic. The control part 104a is close to or far from the hall sensor, and causes the output of the hall sensor to be different.

In some embodiments, the sensing device 104f is a piezoelectric sensor. When the control part 104a is in a predetermined position, pressure is generated on the piezoelectric sensor; when the control component 104a is not in the predetermined position, the pressure disappears, so that the piezoelectric sensor produces different outputs when the control component 104a is in different positions.

In some embodiments, the sensing device 104f is an inductive switch. The inductive switch mainly comprises an infrared inductive switch, a microwave inductive switch, an ultrasonic inductive switch, a piezoelectric inductive switch, an electromagnetic inductive switch, a capacitance inductive switch and the like.

It will be appreciated that other forms of sensing devices may be employed to determine whether the control component 104a is in a predetermined position.

It is understood that the control device 104 may have other configurations to enable the user to trigger the distress device 100 to emit a distress sound by separating the control component 104a from other components. But other embodiments may be used to trigger.

In some embodiments, the mating portion of the control component 104a and the housing 107 forms a detachable snap structure, so that the mating with other components of the control device 104 is more stable, and the two components are not separated by shaking or gravity, which may cause an erroneous help seeking.

In some embodiments, the control component 104a forms a detachable snap-fit structure with other components of the control device 104.

It will be appreciated that the control part 104a and the housing 107 or other parts of the control device 104 may also be configured with other than a removable snap-fit structure so that they do not separate from each other by shaking or gravity, such as using a magnet or the like.

In some embodiments, the control component 104a and/or the housing 107 includes a coupling ring thereon by which the distress device 100 may be hung from another object. If one of the housing 107 or the control component is hung on an object such as a backpack, clothes, a key ring and the like (for example, the control component 104a comprises the connecting ring 104a1), or is attached to an object such as a mobile phone and the like, when the help is required, the other component is only needed to be taken down (when the housing 107 is hung on the other object, the control component 104a is taken down, and when the control component 104a is hung on the other object, the housing 107 is taken down), so that the user can conveniently and quickly ask for the help. In this embodiment, when the user needs to ask for help, the user can close the switch and generate a help sound by simply separating the control unit 104a from the housing 107.

In some embodiments, the control device 104 is a switch, and when the control part 104a is not in the predetermined position, the switch is closed, the circuit is closed, the sound generating component 103 is powered on, and the distress sound is generated.

In some embodiments, the control device 104 outputs a high level or a low level signal, the high level causes the sound generating assembly 103 to generate the distress sound, and the low level causes the sound generating assembly 103 not to generate the distress sound.

In some embodiments, the distress device 100 further includes a processing circuit, an input end of the processing circuit is connected to the control device 104, an output end of the processing circuit is connected to the sound generating assembly 103, and the processing circuit is configured to convert a signal corresponding to a distress output by the control device 104 into an electrical signal that enables the sound generating assembly 103 to generate a distress sound, for example, convert an output corresponding to a distress output by the control device 104 into a high level signal, and enable the buzzer to generate a distress sound; convert it into an electrical signal of a speaker, make the speaker emit distress sound, and so on.

In some embodiments, the distress device 100 further includes a processing circuit, an input end of the processing circuit is connected to the control device 104, an output end of the processing circuit is connected to the sound generating assembly 103, and the processing circuit is configured to read a state of the control device 104, and output an electrical signal to the sound generating assembly 103 to make the sound generating assembly generate a distress sound when the state of the control device 104 corresponds to a distress state. For example, the control device 104 is a switch, the on or off of the switch corresponds to a low level or a high level, the input end of the processing circuit is connected with the switch, the switch is judged to be the high level or the low level, and whether the sound generating assembly 103 is enabled to generate the distress sound is determined according to the judgment result; alternatively, the control device 104 is configured to output an interrupt signal when the control part 104a is not in the predetermined position, so that the processing circuit causes the sound emitting assembly 103 to emit the distress sound in response to the interrupt; alternatively, the processing circuit reads the state of the control device 104 at intervals, and when the state of the help is read, the processing circuit causes the sound generating component to generate the help-seeking sound, and the like.

In one embodiment, the processing circuit may be a processor. The processor may include one or more processing cores, such as a 4-core processor, an 8-core processor, and so forth. The Processor may be at least one of an Application Specific Integrated Circuit (ASIC), a Digital Signal Processor (DSP), a Digital Signal Processing Device (DSPD), a ProgRAMmable Logic Device (PLD), a Field ProgRAMmable Gate Array (FPGA), a Central Processing Unit (CPU), a controller, a microcontroller, and a microprocessor. The processor may execute instructions to implement the corresponding functions.

In some embodiments, the processing circuit may be a voice chip or a voice circuit.

It will be appreciated that the processing circuitry may also be other signal conversion circuitry.

The sound production assembly 103 is used for producing distress sound. The sound emitting component 103 may be a speaker, a buzzer, or the like. The speaker is used for converting the electric signal into sound wave. The loudspeaker can be a traditional film loudspeaker or a piezoelectric ceramic loudspeaker. When the speaker is a piezoelectric ceramic speaker, the speaker can be used for purposes such as converting an electric signal into a sound wave audible to a human being, or converting an electric signal into a sound wave inaudible to a human being to measure a distance. The buzzer is used for making sound after the power is switched on, and the buzzer is mainly divided into a piezoelectric buzzer and an electromagnetic buzzer.

In some embodiments, the sound emitting assembly 103 may also optionally include a sound amplification circuit so that the sound emitted for help is large enough to appeal to the first party.

The sounding component 103 can send out the distress sound continuously; or the sound for help can be sent out according to a preset rule, for example, the sound for help is sent out within minutes first, and then the sound is sent out intermittently, so that the electric quantity is saved; it is also possible to delay a certain time (e.g., 5 minutes) before sending the distress sound, so as to prevent the distress device 100 from being found and damaged by the offender due to the distress sound.

In some embodiments, the distress device 100 further comprises a timing device, such as a timing circuit, to implement functions of intermittently sounding a distress, delaying sounding a distress, and the like.

In some embodiments, the distress device 100 may also optionally include a communication component 105 (not shown). The communication module 105 is used for receiving and transmitting RF (Radio Frequency) signals, also called electromagnetic signals. The communication component 105 communicates with communication networks and other communication devices via electromagnetic signals. The communication module 105 converts an electric signal into an electromagnetic signal to transmit or converts a received electromagnetic signal into an electric signal. Optionally, the communication component 105 comprises: an antenna system, an RF transceiver, one or more amplifiers, a tuner, an oscillator, a digital signal processor, a codec chipset, a subscriber identity module card, and so forth. The communication component 105 may include at least one short-range communication module, such as any module for performing short-range wireless communication based on short-range wireless communication protocols, such as the Hilink protocol, WiFi (IEEE 802.11 protocol), Mesh, bluetooth, ZigBee, Thread, Z-Wave, NFC, UWB, LiFi, etc., and the communication component 105 may also include a long-range communication module, such as any module for performing WLAN, GPRS, 2G/3G/4G/5G long-range communication.

In some embodiments, the memory 102 further stores user information of a user, wherein the user information includes all or part of personal information (such as all or part of name, gender, age, identification number, telephone number, photo, etc.) of the user, all or part of emergency contact information (such as all or part of emergency contact name, relationship with the user, telephone number, etc.), identification information having one-to-one correspondence with the user (such as storing the correspondence between the identification information and the user in a server, so that the corresponding user can be determined according to the identification information, and the personal information of the corresponding user and/or the emergency contact information of the user can be obtained).

The distress device 100 may send the user information to other electronic devices through the communication component 105, for example, when the distress device 100 of the user a is picked up by the user b, the user b may establish a communication connection with the distress device 100 through a mobile phone or other devices to obtain the user information of the user a, and after obtaining the user information, the mobile phone of the user b may send the user information to a server, so that the server gives an alarm to the user or sends a distress message to an emergency contact; the mobile phone of the user b can display the information, so that the user b can alarm or contact the emergency contact; user b's handset may not display this information but provide controls to contact user a's emergency contacts, to contact user a's emergency contacts by text messaging, telephone calls, etc., and so on.

The distress device 100 may broadcast the user information, such as a bluetooth broadcast, through the communication component 105. The identification information which has a one-to-one correspondence relationship with the user can be broadcasted, so that when the help-seeking device 100 of the user a is picked up by the user b, the broadcast information can be received through equipment such as a mobile phone and the like, the obtained identification information is sent to the server, the server determines the user a according to the identification information, and gives an alarm to the user a or sends a help-seeking message to an emergency contact of the user a.

When the communication component 105 comprises a remote communication module, the communication component 105 can send a distress message (e.g., in the form of a short message) directly to an emergency contact or other personnel (e.g., police) upon a distress call.

In some embodiments, the distress device 100 only transmits or broadcasts the distress message when it is seeking help (e.g., sounds a distress sound).

In some embodiments, the distress device 100 ceases to emit distress sounds upon receiving an instruction to cease emitting distress sounds, either directly or indirectly from a distress user, a server, an emergency contact of the distress user, or a law enforcement officer, through the communication component 105. In this way, the distress device 100 can be prevented from disturbing the residents.

For example, when the user considers that there is no danger, an instruction to stop the generation of the distress sound is transmitted to the distress device 100 through an electronic device (application) such as a mobile phone. When the user throws the distress device 100 out and then is difficult to pick up, for example, the user is thrown into a bush, a sewer or the like, the user can also send an instruction for stopping sending the distress sound to the distress device 100 through the mobile phone.

For example, when the server directly or indirectly receives the distress message (for example, the communication component 105 includes a remote communication module and directly sends the distress message to the server; the communication component 105 only includes a short-range communication module, the distress device 100 sends the distress message to the server through the electronic device of the people in heat, or the people in heat send the distress message to the server through the electronic device instead of the distress user), the emergency contact of the distress user may be determined according to the personal information/identification information of the user included in the distress message, or the emergency contact information is extracted from the distress message, an alarm is given to the user or a distress notification is sent to the emergency contact of the user, and then an instruction of stopping sending the distress sound is directly or indirectly sent to the distress device 100.

For example, when the emergency contact of the distress user directly or indirectly receives a distress message (for example, the communication component 105 includes a remote communication module and directly sends the distress message to the emergency contact of the distress user, the communication component 105 only includes a short-range communication module, the distress device 100 sends the distress message to the emergency contact of the distress user through electronic equipment of a hot crowd, or the hot crowd sends the distress message to the emergency contact of the distress user through the electronic equipment, or the distress device 100 sends the distress message to the emergency contact of the distress user through the electronic equipment of the hot crowd and a server, or the like), the emergency contact of the distress user may directly or indirectly send an instruction to stop sending out distress sound to the distress device 100.

For example, when a law enforcement officer (e.g., police) receives a distress message directly or indirectly, an instruction to stop sounding a distress may be directly or indirectly sent to the distress device 100.

In some embodiments, the distress device 100 can only receive an instruction to stop sending out distress sounds from other electronic devices (the distress user, an emergency contact of the distress user, or an electronic device of a law enforcement officer, a server, etc.) through the communication component 105, but cannot trigger the instruction to stop sending out distress sounds through the operation of the input component 104, so that it is difficult for a gangster to stop sending out distress sounds by the distress device 100.

In other embodiments, the distress device 100 can trigger an instruction to stop sounding a distress sound by operating the control device 104, such as placing the control component 104a in a predetermined position.

In the embodiment of the application, whether the SOS sound is sent or not is determined according to the matching or the separation of the control part and other parts of the control device, and the SOS sound can be sent only by separating the control part and other parts when a user encounters danger. When the control component or the shell is hung on objects such as a backpack, clothes and the like, the other component is taken down, and the distress sound can be emitted.

Those skilled in the art will appreciate that the configuration shown in fig. 1 does not constitute a limitation of the distress device 100 and may include more or fewer components than shown, or some components may be combined, or a different arrangement of components may be employed.

It should be noted that, according to the implementation requirement, each component/step described in the embodiment of the present invention may be divided into more components/steps, and two or more components/steps or partial operations of the components/steps may also be combined into a new component/step to achieve the purpose of the embodiment of the present invention.

Fig. 6 shows a block diagram of a distress device 200 according to an exemplary embodiment of the present application.

As shown in fig. 6, the distress apparatus 200 includes a housing 203, a sound emitting assembly 201, and a switch 202.

The sound generating component 201 is used for generating a distress sound and includes sound generating devices such as a speaker and a buzzer.

In some embodiments, the sound emitting component 201 may also include a voice chip to emit more varied sounds.

In some embodiments, the sound generating component 201 is composed of a processor, a memory and a speaker, wherein the memory stores distress voice data, and when a distress sound needs to be generated (for example, when the switch 202 is closed), the processor reads the data from the memory and outputs the data to the speaker.

The opening and closing of the switch 202 controls whether the sound generating assembly 201 generates the distress sound.

In some embodiments, the switch 202 is a key. In order to make the distress device 200 capable of making a distress sound (or making a distress sound all the time) within a certain period of time after the key is pressed, the distress device 200 may further include a timing structure (e.g., a timing circuit), or a processor (e.g., a processor detects the state of the key, continuously makes the distress sound when the key is pressed, and stops making the distress sound when the key is pressed again), etc.

In some embodiments, switch 202 is a self-locking switch, and switch 202 is closed and held when switch 202 is pressed a first time and switch 202 is opened when switch 202 is pressed a second time. For example, the distress device 200 is a circuit (and a housing 203 for wrapping the circuit) formed by serially connecting a power supply, a switch 202 and a sound generating component 201 (such as a buzzer), when a user presses the switch 202 for the first time, the switch 202 is closed and kept in a closed state, the sound generating component 201 continuously generates distress sound, and when the user presses the switch 202 for the second time, the switch 202 is opened, and the sound generating component 201 stops generating the distress sound.

In some embodiments, the switch 202 is a switch including a control component as described in the embodiments of the distress apparatus 100, and is not described herein again.

In some embodiments, the housing 203 has a structure that facilitates movement over the ground, such that the distress device 200 can more easily be moved further after being thrown, increasing the difficulty of an adversary finding the distress device. For example, the housing 203 may be entirely or mostly spherical, ellipsoidal, cylindrical, rectangular or square with rounded corners, or the like.

In some embodiments, the user may throw the distress device 200 out when encountering a danger, so that it is difficult for gangsters to stop making the distress device 200 generate distress sound, thereby enabling the distress device 200 to always ask for help for the user.

In some embodiments, the housing 203 may also optionally include features such as the housing 107 of the distress device 100, such as a connection ring included on the housing 203 to enable the distress device 200 to be hung on another object, the housing 203 being made of a hard material and/or a resilient material, identification information having a one-to-one correspondence with a user included on the housing 203, and so on.

In the embodiment of the application, the user sends out the distress sound by using the distress device 200 to replace the user to ask for help, so that the user can pay attention to danger.

Fig. 7 shows a block diagram of a distress device 300 according to an exemplary embodiment of the present application.

As shown in fig. 7, the distress device 300 includes a housing 303, a sound emitting assembly 301, and a switch 302.

The sound generating component 301 may be the sound generating component 201 of the distress device 200, and will not be described herein.

The shape, material, and other characteristics of the housing 303 are not limited, and for example, the shape, material, and other characteristics of the housing 107 of the distress device 100 and the housing 203 of the distress device 200 may be used, but other shapes, materials, and other characteristics may also be used.

The opening and closing of the switch 302 controls whether the sound generation unit 301 generates a distress sound. The distress device 300 may be different according to different embodiments, and is not limited herein, specifically, when the switch is in the off state, the sound generating assembly 301 generates a distress sound, or when the switch is closed, the sound generating assembly 301 generates a distress sound. For example, when the switch 302, the sound generating component 301 (such as a buzzer) and the power supply are connected in series, the switch 302 is closed, the sound generating component 301 generates the distress sound, the switch 302 is opened, and the sound generating component 301 stops generating the distress sound; the sound generating assembly 301 includes a processor that monitors the state of the switch 302 and causes the sound generating device to generate a distress sound based on the state, the processor may be configured to cause the sound generating device to generate a distress sound when the switch is open or closed, and so on.

The switch 302 is composed of two connection members (a connection member 302b and a connection member 302c) and a control member 302a, and the control member 302a controls the contact or the disconnection of the two connection members corresponding to the on or the off of the switch 302 (when the two connection members are in contact, the switch 302 is closed, and when the two connection members are disconnected, the switch 302 is opened).

When the control unit 302a is engaged with the housing 303 at a predetermined position, the switch 302 is opened or closed, and when the control unit 302a is disengaged from the housing 303, the switch 302 is closed or opened.

For example, the control member 302a has magnetism, and when the connection member 302b or the connection member 302c has one end fixed and the other end movable, and the control member 302a is attached to a certain portion of the housing 303, the movable end of the connection member 302b or the connection member 302c receives a magnetic force and is located at a certain position, and the switch 302 is located at a certain state (open or closed), and when the control member 302a is separated from the portion of the housing 303, the movable end of the connection member 302b or the connection member 302c does not receive a magnetic force and is located at another position, and the switch 302 is located at another state (closed or open).

For another example, the connecting part 302b is disposed opposite to the connecting part 302c, one end of the control part 302a can pass through the housing 303 and be located between the connecting part 302b and the connecting part 302c, and the connecting part 302b, the control part 302a and the connecting part 302c are sequentially contacted, so that the switch is opened (e.g., the control part 302a is made of a non-conductive material) or closed (e.g., a section of the control part 302a located between the connecting part 302b and the connecting part 302c has conductivity); when the control portion 302a is removed from between the connecting portion 302b and the connecting portion 302c, the connecting portion 302b is in contact with the connecting portion 302c (e.g., the connecting portion 302b and/or the connecting portion 302c have elasticity, and after the control portion 302a is removed, the connecting portion with elasticity returns to a position of being in contact with another connecting portion) or is disconnected (e.g., a gap is formed between the connecting portion 302b and the connecting portion 302c after the control portion 302a is removed).

Other configurations may be used between the control member 302a and the housing 303, the connecting member 302b, or the connecting member 302c, such that when the control member 302a is engaged with the housing 303 at a predetermined position, the switch 302 is opened or closed, and when the control member is disengaged from the housing 303, the switch 302 is closed or opened.

In some embodiments, the mating portion of the control component 302a and the housing 303 form a detachable snap structure, so that the mating of the two is more stable, and the two cannot be separated by shaking or gravity, which may cause an erroneous help seeking.

In some embodiments, the control part 302a forms a detachable snap structure with the two connecting parts, such as the two connecting parts clamping the control part 302a by their own elasticity, and so on.

In some embodiments, the control component 302a and/or the housing 303 include a coupling ring thereon by which the distress device 300 may be hung from another object.

In the embodiment of the application, when the control component 302a is matched with the shell 303 at a predetermined position, the switch 302 is opened or closed, and when the control component 302a is separated from the shell 303, the switch 302 is closed or opened, so that when a user needs to ask for help, the user only needs to separate the control component 302a from the shell 303. When the control component 302a or the shell 303 is hung on an object such as a backpack or clothes, the other component is taken down to send out the sound of asking for help.

Fig. 8 shows a block diagram of a distress device 400 according to an exemplary embodiment of the present application.

Generally, the distress apparatus 400 includes: processor 401, memory 402, sound emitting component 403, input component 404, housing 407.

The processor 401 may also include a main processor and a coprocessor, where the main processor is a processor for Processing data in an awake state, and is also called a Central Processing Unit (CPU); a coprocessor is a low power processor for processing data in a standby state. In some embodiments, the processor 401 may be integrated with a GPU (Graphics Processing Unit), which is responsible for rendering and drawing the content required to be displayed by the display screen. In some embodiments, the processor 401 may further include an AI (Artificial Intelligence) processor for processing computing operations related to machine learning.

Memory 402 may include one or more computer-readable storage media, which may be non-transitory. Memory 402 may also include high speed random access memory, as well as non-volatile memory, such as one or more magnetic disk storage devices, flash memory storage devices.

In some embodiments, a non-transitory computer readable storage medium in memory 402 is to store at least one instruction to cause processor 401 to perform the steps of: obtain input information from input component 404; it is determined whether to cause the sound emission component 403 to emit the distress sound based on the input information.

The user generates a distress sound by using the distress apparatus 400 instead of asking for help by himself, so that the user can cope with danger with concentration. In addition, the user can throw the distress device 400 out, so that gangsters can not make the distress device 400 stop making distress sounds, and the distress device 400 can ask for help for the user all the time.

In some embodiments, the memory 402 further stores distress voice data, and the processor 401 reads the distress voice data from the memory 402 and outputs the distress voice data to the sound generating component 403 to make it generate a distress sound.

In some embodiments, the data unit 401 and the memory 402 may be implemented on a single chip or circuit board, such as a music chip, which is not limited in this embodiment.

The sound-making component 403 can make a distress sound continuously; or the sound for help can be sent out according to a preset rule, for example, the sound for help is sent out within minutes first, and then the sound is sent out intermittently, so that the electric quantity is saved; it is also possible to delay a certain time (e.g., 5 minutes) before sending the distress sound, so as to prevent the distress device 400 from being found and damaged by the offender due to the distress sound. Optionally, the processor 401 may select different strategies for making the distress sound according to the user instruction, such as that the user continuously makes the distress sound when clicking a key, that the user intermittently makes the distress sound when double-clicking the key, and that the user delays making the distress sound when triple-clicking (single-clicking, double-clicking, triple-clicking are merely exemplary, and other input modes may be adopted to trigger the instruction, such as that the user sets an input mode corresponding to a different instruction in a setting mode in advance), and so on.

In some embodiments, the distress sound is fixed, such as by a buzzer, or by a designer fixing it to a certain frequency.

In other embodiments, the distress sound is obtained by playing preset distress audio data. The preset distress audio data may be a distress audio file preset by a technician, a distress audio file set by a user (for example, using a mobile phone app or the like to send a selected distress audio file to the distress device 400 through the communication component 405), distress voice data synthesized by a voice synthesis algorithm (for example, receiving text content set by the user, and synthesizing the text content into voice information), and the like. The user can use a mobile phone and the like to input own distress voice, the distress voice can comprise voice contents such as 'rescue', optionally personal information, emergency contact information and the like, and optionally some reward contents, such as only a help alarm or paying money with a certain amount by contacting the emergency contact, so as to encourage others to help oneself.

The sounding component 403 is used for sounding a distress sound. The sounding component 403 may be a speaker, a buzzer, or the like. The speaker is used to convert electrical signals from the processor 401 into sound waves. The loudspeaker can be a traditional film loudspeaker or a piezoelectric ceramic loudspeaker. When the speaker is a piezoelectric ceramic speaker, the speaker can be used for purposes such as converting an electric signal into a sound wave audible to a human being, or converting an electric signal into a sound wave inaudible to a human being to measure a distance. The buzzer is used for making sound after the power is switched on, and the buzzer is mainly divided into a piezoelectric buzzer and an electromagnetic buzzer.

In some embodiments, the sound emitting assembly 403 may also optionally include a sound amplification circuit so that the sound emitted for help is large enough to appeal to the first party.

In some implementations, the input component 404 is a key, touch sensitive sensor, or the like that obtains user input. The processor 401 may distinguish different instructions according to the opening and closing of the keys, the opening and closing time length, the opening and closing frequency, and the like, such as pressing for several seconds, pressing for several times continuously, and the like. The processor 401 may detect the user's contact or disengagement with the touch sensitive sensor through the touch sensitive sensor, the duration of the contact or disengagement, the trace formed by the movement of the finger on the touch sensor, etc. to distinguish between different instructions.

In some embodiments, the different instructions may include one or more of an instruction to sound a help, an instruction to stop sounding a help, an instruction to delay sounding a help, an instruction to stop sounding a help for a period of time and then to sound a help (e.g., a user is forced by a gangster). For example, when the key is pressed, the sound for help is generated, and when the key is pressed again, the generation of the sound for help is stopped. Optionally, the distress device 400 receives a setting instruction of the user to obtain an input mode of different instructions, for example, a setting mode is performed after a long press for several seconds, an input mode corresponding to a certain instruction is set in the setting mode, and for example, the input mode of the instruction for stopping sending the distress sound is set to be a continuous press for several times after a long press for several seconds. Optionally, the distress device 400 further includes a communication module 405, and the communication module 405 receives a setting instruction to obtain different instruction input modes. The user can set the input mode of stopping sending the instructions such as the distress sound and the like in a self-defined mode, so that gangsters can hardly stop the distress device 400 from seeking help, and the success rate of the user for obtaining help is increased.

In some embodiments, when the input information obtained from the input component 404 by the processor 401 is an input satisfying a predetermined rule and the input is interrupted, the processor causes the sound generating component 403 to generate a distress sound. Illustratively, the input component 404 is a key, which the user stops pressing after a continuous press, or stops pressing after a predetermined regular press (e.g., every few seconds) or presses at other regular intervals than the predetermined regular interval, etc.; the input component 404 is a touch sensitive sensor, and the user stops the contact after a continuous contact, or stops the contact after a predetermined regular contact (e.g., a touch every few seconds) or other regular contact outside of a predetermined regular contact, and so on. When a danger is encountered, the user may have no way to trigger the distress device 400 to send out a distress sound, but the user may perceive the danger before the danger occurs, and at this time, the distress device 400 may be regularly operated, so that the distress device 400 knows that the user may be in danger, but the danger does not occur; when a danger occurs, the user can make the distress device 400 sound a distress sound by simply stopping the operation.

In some embodiments, the input meeting the predetermined rule is user feedback after the distress device 400 outputs prompt information at the predetermined rule. For example, the distress device 400 may sound a prompt every few seconds (which may be a fixed value, or take values randomly over an interval at a time, etc.) to prompt the user to operate the input component 404. When the distress device 400 does not receive the feedback operation of the user within a certain time, it is considered that the user is in danger, and the sound generating component 403 is made to generate distress sound.

In some embodiments, when the processor 401 receives a perceived danger instruction (which may be triggered by a preset input to a key or the like as with other instructions), and the input information obtained from the input component 404 is an input satisfying a predetermined rule, the input is interrupted, so that the sound component 403 emits a distress sound.

In some embodiments, the input component 404 may be the control device 104 including the control component 404a in the distress apparatus 100, and the detailed description is given in the corresponding embodiments and is not repeated here.

It is understood that the input component 404 can be implemented by other means besides a button, a touch screen, a switch, etc., such as other structures that can make the sound generating component 403 generate a distress sound when being taken off from an object such as a pendant, a structure that makes the sound generating component 403 generate a distress sound when being thrown away, a structure that makes the sound generating component 403 generate a distress sound when falling to the ground after being thrown away, etc.

The housing 407 encloses the processor 401, memory 402, and other electronic components. The housing 407 may be the same as the housing 107 of the distress device 100, and the detailed description is given in the corresponding embodiment, which is not repeated herein.

In some embodiments, the distress device 400 may also optionally include a communication component 405. The communication component 405 may be the same as the communication component 105 of the distress device 100, and the detailed description is given in the corresponding embodiment, which is not repeated herein.

In some embodiments, the terminal device 400 may also include a bus 408. The processor 401, the memory 402, the sound production component 403, the input component 404, and the communication component 405 may be connected to each other through a bus 408; the bus 408 may be a Peripheral Component Interconnect (PCI) bus, an Extended Industry Standard Architecture (EISA) bus, or the like. The bus 408 may be divided into an address bus, a data bus, a control bus, and the like. For ease of illustration, only one thick line is shown in FIG. 8, but this is not intended to represent only one bus or type of bus. In other embodiments, the memory 402, the sound component 403, the input component 404, the communication component 405, etc. may also be connected directly to an interface of the processor 401.

In some embodiments, the distress device 400 may further include a locating component 409 (not shown in the figures) for locating the current geographic location of the electronic device 400. The Positioning component 409 may be a Positioning component based on a Global Positioning System (GPS) in the united states, a beidou System in china, a graves System in russia, or a galileo System in the european union.

In some embodiments, the distress device 400 may further include one or more sensors 417 (not shown). The one or more sensors 417 include, but are not limited to: an acceleration sensor 411 (not shown), a gyro sensor 412 (not shown), and a pressure sensor 413 (not shown).

The acceleration sensor 411 may detect the magnitude of acceleration in three coordinate axes of a coordinate system established with the distress apparatus 400. For example, the acceleration sensor 411 may be used to detect components of the gravitational acceleration in three coordinate axes. The processor 401 may detect whether the distress apparatus 400 is thrown out or whether the distress apparatus 400 lands according to the gravitational acceleration signal collected by the acceleration sensor 411.

The gyro sensor 412 may detect the body direction and the rotation angle of the distress apparatus 400, and the gyro sensor 412 may cooperate with the acceleration sensor 411 to acquire the motion data of the distress apparatus 400. The processor 401 may implement the following functions according to the data collected by the gyro sensor 412 and the acceleration sensor: determining acceleration in various directions, detecting whether the distress apparatus 400 is thrown out, or whether the distress apparatus 400 lands.

The pressure sensor 413 may be provided on the entire housing of the distress device 400 or on a partial housing. When the pressure sensor 413 is provided on the entire housing of the distress apparatus 400, the processor 401 determines whether a ground is touched based on pressure data collected by the pressure sensor 413, and causes the sound emitting assembly 403 to emit a distress sound when the ground is detected. When the pressure sensor 413 is disposed on a partial housing of the distress device 400, user input may be obtained, such as user instructions to differentiate between different pressure levels.

In one example, the sensor performs detection at a predetermined detection frequency (corresponding to a detection period) to obtain sensing data (e.g., sensing data of an acceleration sensor; sensing data of an acceleration sensor and a gyro sensor). In one example, the sensor outputs the sensed data to the processor 401 at a preset sampling frequency (corresponding to a sampling period), that is, the sensor does not output all of the sensed data to the processor 401, but outputs a part of the sensed data to the processor 401 in a sampling manner. The detection frequency is usually higher than the sampling frequency, for example, the detection frequency can reach 1ms for sampling 1 time, and the sampling frequency can reach 40ms to 200ms for reporting once.

In one embodiment, the processor 401 determines whether the distress device 400 has a free-fall motion exceeding a preset time period or a preset falling distance according to the sensing data, and causes the sound generating assembly 403 to generate a distress sound when the free-fall motion exceeding the preset time period or the preset falling distance occurs. Therefore, when the user needs to ask for help, the user throws the help-seeking device 400 out, and the help-seeking device 400 sends out a help-seeking sound after detecting that the help-seeking device is thrown out.

In one example, the preset duration may be set according to an application scenario. For example, the preset time period may be 0.5 s. When the acceleration value of each of the consecutive sampling periods (the total duration of the consecutive sampling periods is greater than the preset duration) acquired by the processor 401 is greater than the first acceleration threshold, it is determined that the distress device 400 has a free-fall motion exceeding the preset duration. For example, the first acceleration threshold is, for example, 0.3G, where G is the acceleration of gravity.

In one example, the preset falling distance may be set according to an application scenario. For example, the preset falling distance may be 1m or 2 m. When the acceleration value of each of the consecutive sampling periods acquired by the processor 401 is greater than the preset first acceleration threshold value, and the total falling distance in the consecutive sampling periods is calculated to exceed the preset falling distance, it is determined that the distress device 400 performs a free-falling body movement exceeding the preset falling distance.

Other values may be used for the first acceleration threshold, the preset duration, the preset falling distance, and other parameters to distinguish the free-fall movement (thrown) from the shaking movement of the distress apparatus 400.

In one embodiment, the processor 401 may cause the sound emitting assembly 403 to emit a distress sound when it determines that the distress device 400 is in violent movement based on the sensed data. For example, the distress device 400 has an acceleration value greater than a second acceleration threshold. The second acceleration threshold is, for example, 2G, where G is the acceleration of gravity.

Other values may be used for the second acceleration threshold to distinguish the motion of the distress device 400, such as landing (being thrown) from shaking.

Those skilled in the art will appreciate that the configuration shown in fig. 8 does not constitute a limitation of the distress device 400 and may include more or fewer components than shown, or combine certain components, or employ a different arrangement of components.

Fig. 9 shows a block diagram of a distress device 500 according to an exemplary embodiment of the present application.

As shown in fig. 9, the distress device 500 includes a housing 503, a sound generating assembly 501, a collision detecting module 502, and a processing module 504.

The shape, material, and other characteristics of the housing 503 are not limited, and for example, the shape, material, and other characteristics of the housing 107 of the distress device 100 and the housing 203 of the distress device 200 may be used, but other shapes, materials, and other characteristics may also be used.

The sound emitting component 501 includes a sound emitting device, such as a speaker, a buzzer, etc.

The collision detection module 502 is configured to output a collision signal when a collision is detected. If the user throws the distress device 500 out, the distress device 500 falls to the ground and collides with the ground.

In one embodiment, the collision detection module 502 is a collision sensor. Most of the collision sensors adopt an inertial type mechanical switch structure, which is equivalent to a control switch. The collision sensors can be generally classified into a rolling ball type collision sensor, a rolling shaft type collision sensor, an eccentric hammer type collision sensor, a mercury switch type collision sensor, a resistance strain gauge type collision sensor, and a piezoelectric effect type collision sensor according to their structures. The present embodiment does not limit the category, parameters, and the like of the collision sensor, and only needs to make the user fall to the ground after throwing (upward throwing, downward throwing with force, and the like) and fall to the ground from a free falling body with a certain height (such as a height of 1 meter, a height of 1.5 meters, and the like), so that the sound generating assembly 501 generates the distress sound (the collision detection module 502 outputs a collision signal, and the collision signal makes the sound generating assembly 501 generate the distress sound), and the user does not generate the distress sound under other conditions (such as the user walks, runs, and the like to drive the distress device 500 to shake). Optionally, the collision detection module 502 includes a plurality of collision sensors.

In one embodiment, the collision detection module 502 is a Pressure Transducer (Pressure Transducer) disposed on an outer surface or an inner surface of the housing 503. A pressure sensor is a device or apparatus that senses a pressure signal and converts the pressure signal into a usable output electrical signal according to a certain rule. Pressure sensors can be classified into gauge pressure sensors, differential pressure sensors, and absolute pressure sensors according to different types of test pressures. Pressure sensors can be classified into resistive strain gauge pressure sensors, semiconductor strain gauge pressure sensors, piezoresistive pressure sensors, inductive pressure sensors, capacitive pressure sensors, resonant pressure sensors, capacitive acceleration sensors, and the like. When the user throws the help-seeking device 500 and the help-seeking device falls to the ground, the user collides with the ground and receives a large impulsive force, so that the output of the pressure sensor changes; or the housing 503 is deformed by the collision, so that the pressure sensor is stressed and the output is changed. The present embodiment does not limit the category, parameters, and the like of the pressure sensor, and only needs to make the user fall to the ground after throwing (upward throwing, downward throwing with force, and the like) and fall to the ground freely from a certain height (such as a height of 1 meter, a height of 1.5 meters, and the like), so that the sound generating assembly 501 generates the distress sound (the pressure value output by the collision detection module 502 is greater than the preset value, so that the sound generating assembly 501 generates the distress sound), and does not generate the distress sound under other conditions (such as the user walks, runs, and the like to drive the distress device 500 to shake).

The collision detection module 502 may also detect whether the distress device 500 is thrown out in other manners, for example, an acceleration sensor is used to measure acceleration, and when the average acceleration of the distress device 500 in a certain direction exceeds a certain threshold at a certain time, the sound generation assembly 501 generates a distress sound.

And the processing module 504 is configured to convert the collision signal into an electrical signal for making the sound generating assembly generate a distress sound.

In one embodiment, the collision signal is a transient signal, and the processing module 504 is a self-holding circuit to convert the transient signal into a high level signal, so that the sound generating assembly 501 continuously generates the distress sound.

In one embodiment, the processing module 504 is a processor that obtains the collision signal from the collision detection module 502 and makes a sound component (e.g., a speaker) emit a distress sound after obtaining the collision signal. If the input end of the processor is connected with the collision detection module 502, and the output end of the processor is connected with the sound production assembly, after the input end receives a collision signal, an electric signal which enables the sound production assembly to produce sound is output from the output end; or, an interrupt interface of the processor is connected to the collision detection module 502, the collision detection module outputs an interrupt signal after detecting a collision, and the processor receives the interrupt signal and then makes the sound generation assembly 501 generate a distress sound.

The processing module 504 may also adopt other processing circuits as long as it can make the sound generating component 501 generate the distress sound when the collision detecting module 502 detects the collision.

The distress device 500 may be used to sound a distress after being thrown so that the user may simply sound a distress.

In some embodiments, the defense function portion of the defense tool 600 is integrated with the help function portion and is not separable during use.
