Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. "A plurality of" means two or more.

[0042] This application provides an ultrasound device that can be used on humans and various animals.

[0043] Ultrasonic equipment can be either wireless or wired ultrasonic probes.

[0044] Please see Figure 1 The ultrasonic device includes a housing assembly 10, a sound head 20, a main board 30, a processor, a positioning unit 40, and a magnetic barrier unit.

[0045] The housing assembly 10 has a mounting cavity. The mounting cavity is used to mount various components of the probe. Exemplarily, the outer wall of the housing assembly 10 has a handhold area, which the user operates the ultrasound device by holding the handhold area of ​​the housing.

[0046] The acoustic head 20 is disposed on the housing assembly 10 and is used to emit and receive ultrasonic signals. The housing assembly 10 provides mounting support for the acoustic head 20.

[0047] In some embodiments, the housing assembly 10 is generally elongated for easy gripping by the user, and the sound head 20 is located at one end of the housing assembly 10 in the length direction.

[0048] The mainboard 30 is located in the mounting cavity and contains an ultrasonic transceiver circuit, which is electrically connected to the acoustic head 20. The ultrasonic transceiver circuit consists of an ultrasonic transmitting circuit and an ultrasonic receiving circuit. The ultrasonic transmitting circuit transmits electrical signals to the acoustic head 20, causing the acoustic head 20 to generate ultrasonic signals. The ultrasonic receiving circuit receives reflected echo signals from the acoustic head 20. It should be noted that reflected echo signals refer to the ultrasonic signals reflected back from the object being detected when the ultrasonic signal acts on it.

[0049] The processor is located in the mounting cavity and is used to process the reflected echo signal received by the acoustic head 20 and generate an electrical signal. In other words, the ultrasonic device of this application embodiment is also a device with data processing capabilities.

[0050] Traditional ultrasound equipment receives ultrasound echo signals from a sound head. After the sound is converted to electricity, the original analog signal is transmitted to a host computer outside the ultrasound equipment via a high-frequency cable. The host computer then performs signal processing, meaning that all beamforming, signal processing, and image reconstruction are done by the host computer, and the ultrasound equipment only acts as a sensor.

[0051] In the ultrasonic device of this application embodiment, the acoustic head 20 receives ultrasonic echo signals, performs acoustic-to-electric conversion, and then the processor processes the signals (such as beamforming and compression). The processed data can be transmitted as digital signals to the host or other terminal devices (such as mobile phones, tablets, etc.) via USB, Thunderbolt, or wireless networks (such as Wi-Fi), instead of analog cables. The host or other terminal devices only need post-processing / display.

[0052] The ultrasound device described in this application embodiment may also be referred to as a portable or handheld ultrasound device.

[0053] The positioning unit 40 is disposed in the mounting cavity and is used to transmit and receive radio waves for wireless communication with external devices; wherein the radio waves can penetrate the housing assembly 10. That is, the radio waves can penetrate the housing assembly 10, and the signal strength meets the application requirements. Thus, the positioning unit 40 is not externally mounted on the housing assembly 10, and therefore, the positioning unit 40 does not affect the daily use of the ultrasonic equipment.

[0054] The positioning unit 40 assists the user in locating the ultrasound equipment by communicating wirelessly with external devices (e.g., mobile phones, tablets, the aforementioned ultrasound host, etc.).

[0055] For example, external devices can make the positioning module emit sound, vibration, or light to remind the user to find the ultrasound device; or display on the interface of the external device the distance and direction between the ultrasound device and the external device.

[0056] The positioning unit 40 can employ any technology, such as satellite long-range communication technology or short-range communication technology. Compared to satellite long-range communication technology, short-range communication technology consumes less power, which helps reduce the power consumption of the positioning unit 40.

[0057] For example, the positioning unit 40 includes at least one of a Bluetooth unit, a ZigBee unit, an NFC unit, an infrared communication unit, and a wireless local area network unit. That is, the positioning unit 40 uses near-field communication technology.

[0058] In some embodiments, the positioning unit 40 may employ an AirTag module (a Bluetooth tracking module released by Apple). The AirTag module enables short-range communication with iOS (Apple's mobile operating system) devices via Bluetooth / NFC. When the ultrasound device is too far from an external device to utilize short-range wireless communication technology, given the global reach of iOS devices, an iOS device (such as an iPhone / iPad) is likely to be nearby. In this case, the AirTag module within the ultrasound device will automatically establish a wireless connection with this nearby iOS device and report its address to the cloud (Find My network) through that device. The cloud will then notify the external device of the ultrasound device's address. Thus, regardless of distance, the ultrasound device can be located as long as there is a nearby iOS device.

[0059] An electromagnetic blocking structure is at least partially disposed between the main board 30 and the positioning unit 40 to shield or reduce electromagnetic interference between the ultrasonic transceiver circuit and the positioning unit 40; and / or, an electromagnetic blocking structure is at least partially disposed between the acoustic head 20 and the positioning unit 40 to shield or reduce electromagnetic interference between the acoustic head 20 and the positioning unit 40.

[0060] Electromagnetic barrier structure refers to all structures that have electromagnetic shielding function.

[0061] The ultrasonic device of this application embodiment, due to the electromagnetic shielding effect of the electromagnetic barrier structure, is beneficial to shielding or reducing the electromagnetic interference of the positioning unit 40 on the ultrasonic signal, and reducing the impact of the positioning unit 40 on the ultrasonic imaging quality.

[0062] The ultrasonic transceiver circuit can be located on the side of the main board 30 facing the positioning unit 40, or on the side of the main board 30 facing away from the positioning unit 40; or part of it can be located on the side of the main board 30 facing the positioning unit 40, and the other part can be located on the side of the main board 30 facing away from the positioning unit 40.

[0063] In some embodiments, the ultrasonic transceiver circuit is located on the side of the motherboard 30 away from the positioning unit 40. On the one hand, the motherboard 30 itself can also provide electromagnetic shielding to a certain extent, further reducing electromagnetic interference from the positioning unit 40 to the ultrasonic transceiver circuit. In addition, it can make full use of the space on the side of the motherboard 30 away from the positioning unit 40.

[0064] In some embodiments, the ultrasound device further includes a wireless transmission unit disposed in the mounting cavity. The electrical signal processed by the processor is transmitted to the receiving device through the wireless transmission unit. In other words, the ultrasound device is a wireless ultrasound device, eliminating the need for cable connections to external devices and making it easy to carry. It should be noted that the receiving device refers to a device that receives the signal processed by the processor. After receiving the processed signal, the receiving device can display ultrasound images.

[0065] In some embodiments, the ultrasonic device includes a button 51 and a button circuit board 52, with the button 51 exposed on the outer surface of the housing assembly 10 and engaging with the button circuit board 52.

[0066] The number of buttons 51 is unlimited; there can be one or more. In this embodiment, "multiple" means no less than two.

[0067] When the user presses button 51, the corresponding function of button 51 can be performed. For example, the function of button 51 can be to select function options or adjust option parameters.

[0068] In embodiments where there are multiple buttons 51, all buttons 51 can share the same button circuit board 52.

[0069] In some embodiments, the ultrasound device also includes an indicator light that is electrically connected to the button circuit board 52, and the light of the indicator light can be displayed on the outer surface of the ultrasound device.

[0070] In some embodiments, the positioning unit 40 is fixed to the keypad circuit board 52, and the positioning unit 40 can be powered by the circuitry on the keypad circuit board 52. This allows for full utilization of the circuitry on the keypad circuit board 52, improving integration.

[0071] In some embodiments, the positioning unit 40 is fixed to the side of the button circuit board 52 facing the button 51. That is, the positioning unit 40 is fixed to the side of the button circuit board 52 away from the motherboard 30. This means that the button circuit board 52 and the inner surface of the corresponding housing assembly 10 are spaced apart to allow for the installation of the button 51. In this embodiment, the space between the button circuit board 52 and the inner surface of the housing assembly 10 can be fully utilized to arrange the positioning unit 40, resulting in a compact structure that does not occupy other space. Thus, even with the addition of the positioning unit 40, the structure of the existing ultrasonic equipment can be maintained or minimally modified, facilitating the upgrade of the ultrasonic equipment at a lower cost.

[0072] In some embodiments, the projections onto the button circuit board 52, the positioning unit 40 and the button 51 do not overlap, that is, the positioning unit 40 and the button 51 are staggered. In this way, the positioning unit 40 can be prevented from affecting the pressing stroke of the button 51.

[0073] In some embodiments, the button circuit board 52 is arranged parallel to the main board 30. This helps to reduce the space occupied by both in the stacking direction, which is beneficial for the miniaturization design of the ultrasound device and makes it easier for the user to hold.

[0074] In some embodiments, the overall size of the positioning unit 40 does not exceed 20mm*10mm*3mm (millimeters). The overall size of the positioning unit 40 can be understood as the minimum size of the cuboid space required to place the positioning unit 40 within it. The small size of the positioning unit 40 reduces the required installation space, making it easy to integrate into ultrasonic equipment.

[0075] Preferably, the dimension of the positioning unit 40 in the direction perpendicular to the surface of the button circuit board 52 does not exceed 3mm.

[0076] In some embodiments, the ultrasound device includes a power supply 60 that supplies power to at least the mainboard 30 and the acoustic probe 20. That is, the power supply 60 supplies power to the ultrasound device.

[0077] The power supply device 60 includes a power management unit 62 and a battery 61 electrically connected, with the battery 61 receiving or outputting power through the power management unit 62. The battery 61 is used to provide electrical energy, and the power management unit 62 is used for at least power conversion. The functions of the power management unit 62 may also include at least one of power monitoring, power distribution, and battery 61 management.

[0078] Power conversion refers to converting the input voltage into the desired stable output voltage.

[0079] Battery 61 can be a dry cell battery (also known as a disposable battery). Battery 61 can also be a rechargeable battery, meaning it can be charged.

[0080] In some embodiments, the ultrasound device includes a charging interface 70, which is electrically connected to a power management unit 62 for charging the battery 61 via the power management unit 62 when an external power source is connected. The battery 61 is a rechargeable battery, thus eliminating the need for the user to remove and install the battery 61, improving the ease of use of the ultrasound device.

[0081] In some embodiments, the power supply unit 60 and the motherboard 30 are stacked along a first direction, i.e., the power supply unit 60 faces the surface of the motherboard 30. The positioning unit 40 is located on the side of the power supply unit 60 away from the motherboard 30, and the power supply unit 60 constitutes at least a part of the electromagnetic shielding structure. That is, the projection of the power supply unit 60 onto the plane of the motherboard 30 between the motherboard 30 and the positioning unit 40 at least partially overlaps with the positioning unit 40. In this embodiment, the power supply unit 60 is used to shield or reduce electromagnetic interference between the positioning unit 40 and the ultrasonic transceiver circuit, eliminating the need for an additional electromagnetic shielding structure and contributing to a compact structure.

[0082] In some embodiments, the sound head 20 is located on one side of the power supply device 60 in the second direction, and the sound head 20 in the first direction from the motherboard 30 to the positioning unit 40 does not exceed the power supply device 60. That is, the power supply device 60 is located on the virtual connection line between the positioning unit 40 and the sound head 20. Electromagnetic waves radiated from the positioning unit 40 to the location of the sound head 20, or electromagnetic waves radiated from the sound head 20 to the location of the positioning unit 40, will be blocked by the power supply device 60. The power supply device 60 is beneficial for shielding or reducing electromagnetic interference between the positioning unit 40 and the sound head 20.

[0083] In some embodiments, the power management unit 62 and the battery 61 are arranged side-by-side along a second direction, which intersects with the first direction. That is, in the projection onto the plane of the motherboard 30, the power management unit 62 and the battery 61 are laid flat and do not overlap. This facilitates a smaller size design for the ultrasonic device in the first direction.

[0084] Preferably, the second direction is perpendicular to the first direction. More preferably, the second direction is parallel to the length direction of the housing assembly 10.

[0085] In some embodiments, the charging interface 70 and the speaker 20 are located on opposite sides of the power supply device 60 in the second direction. That is, the charging interface 70, the power supply device 60, and the speaker 20 are arranged sequentially along the second direction, so as to make full use of the space in the housing assembly 10 in the second direction.

[0086] Preferably, the power management unit 62 is located between the charging interface 70 and the battery 61. In this way, the power management unit 62 is arranged close to the charging interface 70, which helps to shorten the circuit length between the two and facilitates the wiring connection.

[0087] In some embodiments, the power supply 60 supplies power to the positioning unit 40. That is, there is no need to configure an additional power supply for the positioning unit 40. The positioning unit 40, the acoustic head 20, the main board 30, etc., share the same power supply 60. In other words, all the devices in the ultrasonic equipment that require power share the same power supply 60.

[0088] In some embodiments, the positioning unit 40 is fixed to the side of the keypad circuit board 52 away from the motherboard 30, and the power supply device 60 supplies power to the positioning unit 40 through the circuit on the keypad circuit board 52.

[0089] In this way, the circuitry on the button circuit board 52 can be fully utilized to power the positioning unit 40, reducing wiring harnesses.

[0090] It should be noted that the positioning unit 40 also needs to use the button circuit board 52 to transmit communication signals.

[0091] In some embodiments, the power supply device 60 is electrically connected to the ultrasonic transceiver circuit via a first circuit, and the power supply device 60 is electrically connected to the positioning unit 40 via a second circuit. The power supply device 60 can supply power to either the first circuit or the second circuit, or supply power to both the first circuit and the second circuit simultaneously.

[0092] It should be noted that "first circuit" refers to the general term for the path of power transmission, while "second circuit" refers to the general term for the path of circuit transmission. For example, the first circuit may include printed circuits and / or circuits formed by wires on the motherboard 30. The second circuit may include printed circuits and / or circuits formed by wires on the button circuit board 52.

[0093] The power supply device 60 described above can supply power to either the first circuit or the second circuit, or simultaneously to both the first circuit and the second circuit. This means that the power supply device 60 can achieve these power supply states, but it does not require that the ultrasonic equipment actually uses these functions during its use.

[0094] For example, when the power supply 60 has sufficient power, it simultaneously supplies power to both the first and second circuits, meaning it simultaneously powers both the sound head 20 and the positioning unit 40. When the power supply 60's power level falls below the reserved level (e.g., only 20% of the power remains), the first circuit is cut off, the sound head 20 cannot be activated, and the power supply 60 only powers the positioning unit 40, thus extending the standby time of the positioning unit 40.

[0095] When a certain type of user does not require the ultrasonic equipment to have a positioning function, the second circuit can be switched through hardware or software logic before the ultrasonic equipment leaves the factory, so that the second circuit cannot be powered on under any circumstances, and the positioning unit 40 loses its positioning function.

[0096] In this way, regardless of whether the ultrasonic equipment actually uses the positioning function, it can be implemented on the same model of ultrasonic equipment without changing the production materials and assembly line, which facilitates production and manufacturing.

[0097] This application provides an ultrasonic device, including a housing assembly 10, a sound head 20, a main board 30, a processor, and a positioning unit 40.

[0098] The housing assembly 10 has a mounting cavity. The housing assembly 10 can be any of the housing assemblies described above, and will not be described again here.

[0099] The acoustic head 20 is disposed on the housing assembly 10 and is used to emit and receive ultrasonic signals.

[0100] The motherboard 30 is located in the mounting cavity. An ultrasonic transceiver circuit is provided on the first side of the motherboard 30. The ultrasonic transceiver circuit is electrically connected to the sound head 20.

[0101] The processor is located in the mounting cavity and electrically connected to the sound head 20. It is used to process the reflected echo signal received by the sound head 20 and generate an electrical signal.

[0102] The positioning unit 40 is used to transmit and receive radio waves for wireless communication with external devices, wherein the radio waves are able to pass through the housing assembly 10.

[0103] The positioning unit 40 is located on the side of the main board 30 away from the ultrasonic transceiver circuit, that is, the second side of the positioning unit 40 facing the main board 30. The main board 30 is used to shield or reduce electromagnetic interference between the ultrasonic transceiver circuit and the positioning unit 40.

[0104] The first and second sides are the opposite surfaces of the motherboard 30.

[0105] The motherboard 30 usually has a ground plane, which can reduce noise interference and also shield or reduce electromagnetic interference (EMI) and signal crosstalk.

[0106] In this embodiment, the motherboard 30 is used to shield or reduce electromagnetic interference between the positioning unit 40 and the ultrasonic transceiver circuit, eliminating the need for an additional electromagnetic shielding structure, which is beneficial for the compact structure of the ultrasonic equipment.

[0107] In some embodiments, the ultrasonic device includes a power supply 60, which is stacked on top of the motherboard 30. The positioning unit 40 is located on the side of the power supply 60 away from the motherboard 30. That is, the positioning unit 40 and the motherboard 30 are located on opposite sides of the power supply 60. The power supply 60 acts as a barrier between the positioning unit 40 and the motherboard 30, and it also serves to resist electromagnetic interference, thereby further reducing electromagnetic interference between the positioning unit 40 and the ultrasonic transceiver circuit.

[0108] The power supply device 60 can be any of the power supply devices 60 in the above embodiments. For example, the power supply device 60 includes the battery 61 and the power management unit 62 in any of the above embodiments.

[0109] In some embodiments, the ultrasonic device includes a button 51 and a button circuit board 52. The button 51 is exposed on the outer surface of the housing assembly 10, and the button 51 cooperates with the button circuit board 52. A positioning unit 40 is fixed to the side of the button circuit board 52 facing the button 51. That is, the positioning unit 40 is fixed to the side of the button circuit board 52 away from the main board 30.

[0110] When the user presses button 51, the corresponding function of button 51 can be performed. For example, the function of button 51 can be to select function options or adjust option parameters.

[0111] It can be understood that when button 51 is not pressed, there is a certain distance between button 51 and button circuit board 52, which is not less than the pressing stroke of button 51, and button circuit board 52 and the inner surface of the corresponding housing assembly 10 also maintain a distance. In this embodiment, the spacing between button circuit board 52 and the inner surface of housing assembly 10 can be fully utilized to arrange positioning unit 40, resulting in a compact structure that does not occupy other space. Thus, even if positioning unit 40 is added, the structure of the existing ultrasonic equipment can be changed without alteration or with minimal alteration, facilitating the upgrading of ultrasonic equipment at a lower cost.

[0112] Some structures of the ultrasonic equipment can refer to the structure of the ultrasonic equipment in any of the above embodiments, and will not be described again here.
