[0050] See also Figure 1 and Figure 2 As shown, the present application provides a contact sound transmission device 100. The contact sound transmission device 100 is applied to a medical device 200. The contact sound transmission device 100 includes a sound transmission drive module 10 and a voice vibration module 20. The sound transmission drive module 10 is arranged on the medical device 200, and is used to convert the voice command sent by the console device end of the medical device 200 into a voice excitation signal; the voice command includes the real-time prompt information of the operator on the console device end and / or the fixed prompt information of the device. The voice vibration module 20 is connected to the sound transmission drive module 10, and is used to convert the voice excitation signal into a voice vibration signal. The voice vibration module 20 is also used to contact the body surface of the subject through a fixed component to transmit the voice vibration signal to the subject.

[0051] In this embodiment, the medical device 200 can be a computer tomography (CT) device or a magnetic resonance imaging (MRI) device. The voice command can be a voice signal corresponding to the prompt sound of the console device end or / and the voice of the device operator, including the operator's real-time prompt information or / and the device's fixed prompt information. The voice transmission drive module 10 can receive the voice signal corresponding to the prompt sound of the console device end or / and the voice of the device operator, and convert the voice command into a voice excitation signal. Through the sound transmission drive module 10, the prompt sound of the console device end or / and the voice of the device operator are transmitted in the form of a circuit transmission signal to form a voice excitation signal containing the operator's real-time prompt information or / and the device's fixed prompt information, which is transmitted in the form of signal frequency and amplitude. The sound transmission drive module 10 and the voice vibration module 20 can be connected by wireless communication or wired communication.

[0052] The voice vibration module 20 performs vibration of corresponding frequency and amplitude according to the voice excitation signal to form a voice vibration signal of mechanical vibration. The voice vibration signal also contains real-time prompt information of the operator or / and fixed prompt information of the device. Through the fixed component, the voice vibration module 20 can be fixed on the body surface of the measured person, so that the voice vibration module 20 is fully in contact with the body surface of the measured person, avoiding the problem of falling off during the signal transmission process, so as to ensure that the real-time prompt information of the operator at the console device end or / and the fixed prompt information of the device are accurately transmitted to the measured person. The voice vibration signal directly acts on the body of the measured person through the voice vibration module 20. The contact part between the voice vibration module 20 and the measured person can be a leg, an arm, a neck, a chest or a head, etc., to ensure that the voice vibration module 20 is in contact with the body surface of the measured person. The voice vibration signal is transmitted to the inner ear and the auditory nerve of the measured person through the skin, muscles and bones of the measured person, so that the measured person can clearly know the real-time prompt information of the operator or / and the fixed prompt information of the device. Wherein, the measured person can be understood as a person using the contact sound transmission device 100, which can be the measured person or other users.

[0053] Through the contact sound transmission device 100 provided by the present application, the voice command sent by the console device (the voice command includes the operator's real-time prompt information and / or the device's fixed prompt information) is transmitted to the subject in the form of circuit transmission signal and mechanical vibration transmission signal through the sound transmission drive module 10 and the voice vibration module 20. Compared with the traditional medical equipment that transmits prompt sound or voice to the subject through a speaker, during the transmission process of the contact sound transmission device 100 provided by the present application, the operator's real-time prompt information and / or the device's fixed prompt information will not be affected by air transmission loss, so that the operator's real-time prompt information and / or the device's fixed prompt information can be quickly and accurately transmitted to the subject.

[0054] Furthermore, through the contact sound transmission device 100 provided by the present application, the voice command is directly transmitted to the subject through the skin, muscles and bones of the subject, which can avoid the interference of the working noise of the equipment frame rotation and internal components on the operator's real-time prompt information and / or the fixed prompt information of the equipment. Through the contact sound transmission device 100, the subject can accurately and clearly hear the operator's real-time prompt information and / or the fixed prompt information of the equipment, and make corresponding inspection actions according to the operator's real-time prompt information and / or the fixed prompt information of the equipment, so that the communication efficiency between the equipment end and the subject is improved, thereby improving the inspection efficiency.

[0055] See also Figure 3 In one embodiment, the sound transmission driving module 10 includes a voice collection module 111, a signal processing module 112 and a control module 113. The voice collection module 111 is used to receive voice commands. The signal processing module 112 is connected to the voice collection module 111, and is used to convert the voice commands into recognizable digital signals and perform a cyclic redundancy check on the voice commands.

[0056] The first end of the control module 113 is used to receive the first voice control signal sent by the console device. The second end of the control module 113 is connected to the signal processing module 112, and is used to merge the first voice control signal with the recognizable digital signal to obtain a voice digital conversion signal. The third end of the control module 113 is connected to the digital-to-analog conversion module 120, and is used to send the voice digital conversion signal to the digital-to-analog conversion module 120.

[0057] In this embodiment, the voice acquisition module 111 is used to receive voice commands sent by the console device. The voice command can be a voice analog signal or a voice digital signal. In one embodiment, when the voice command is a voice analog signal, the voice acquisition module 111 is directly connected to the microphone or the voice collection device of the medical device. When the voice command is a digital audio signal, the voice acquisition module 111 is indirectly connected to the microphone or the voice collection device of the medical device through an audio signal input card. In this embodiment, the voice acquisition module 111 can process both the voice analog signal and the voice digital signal.

[0058] The signal processing module 112 pre-processes the voice command and converts the voice command into a digital signal recognizable by the digital-to-analog conversion module 120. The cyclic redundancy check code is transmitted or stored together with the data. The signal processing module 112 performs a cyclic redundancy check (CRC) on the voice command to detect whether an error occurs during signal transmission or storage to ensure the integrity and reliability of the transmitted voice command.

[0059] The first voice control signal can be understood as a control signal for the device-side operator to change the amplitude and frequency of the output voice on the system, so that the subject can obtain a loud and comfortable sound. In one embodiment, the first end of the control module 113 communicates wirelessly or wired with the device-side system, and can send the first voice control signal to the control module 113 in a timely manner. The control module 113 adjusts the sound effect and volume of the voice command during the transmission process according to the first voice control signal, so that the sound transmitted to the subject is loud and comfortable.

[0060] The second end of the control module 113 is connected to the signal processing module 112 for receiving a recognizable digital signal. The control module 113 fuses the first voice control signal with the recognizable digital signal to obtain a voice digital conversion signal. In one embodiment, the first voice control signal is fused with the recognizable digital signal by a data encoding method, an amplitude modulation method, a frequency modulation method, a time series encoding method, etc. to obtain a voice digital conversion signal. The voice digital conversion signal contains amplitude and frequency control information and voice information transmitted by the device end. After receiving the voice digital conversion signal, the digital-to-analog conversion module 120 converts the voice digital conversion signal into a voice analog signal as a voice excitation signal for driving the voice vibration module 20.

[0061] The voice vibration module 20 receives the voice excitation signal and converts the voice excitation signal into a mechanical voice vibration signal. Through the voice acquisition module 111, the signal processing module 112 and the control module 113, the amplitude of the voice excitation signal can be regulated and controlled, and then the vibration amplitude of the voice vibration module 20 is driven to regulate the volume heard by the testee. At the same time, through the voice acquisition module 111, the signal processing module 112 and the control module 113, the frequency of the voice excitation signal can also be changed, and then the vibration frequency of the voice vibration module 20 is driven to regulate the sound effect heard by the testee, which can also be understood as the sharpness (high frequency) or roughness (low frequency) of the sound heard by the testee.

[0062] In one embodiment, the first end of the control module 113 is also used to receive a control instruction sent by the console device end, and adjust the working state of the sound transmission drive module 10 and the working state of the voice vibration module 20 according to the control instruction.

[0063] In this embodiment, the first end of the control module 113 communicates wirelessly or by wire with the device-side system, and can communicate with the device-side system, and timely receive the control instructions sent by the device-side to adjust the working state of the sound transmission drive module 10 and the working state of the voice vibration module 20, so as to timely adjust the working state of the contact sound transmission device 100 and take timely countermeasures. By wirelessly or by wired communication between the control module 113 and the device-side system, the working state of the sound transmission drive module 10 and the working state of the voice vibration module 20 can be remotely controlled, thereby improving the convenience, efficiency and flexibility of the contact sound transmission device 100.

[0064] In one embodiment, the first end of the control module 113 is also used to receive control instructions sent by the console device end, such as: control instructions for the first voice control signal, instructions for restarting the sound transmission drive module 10 and / or the voice vibration module 20, or instructions for turning off the board power supply of the sound transmission drive module 10, etc.

[0065] In one embodiment, the sound transmission driving module 10 further includes a voice control module 114. The voice control module 114 is connected to the fourth end of the control module 113, and is used to send a second voice control signal to the control module 113 according to the voice control instruction triggered by the subject. The control module 113 is used to fuse the second voice control signal with the recognizable digital signal to obtain a voice digital conversion signal.

[0066] In this embodiment, the voice control module 114 can be an audio controller, a device or software tool for adjusting an audio signal. The voice control module 114 is connected to the fourth end of the control module 113, which can be a wired communication connection or a wireless communication connection. In one embodiment, the voice control module 114 can be set as a hardware device on the sound transmission drive module 10, and the subject can choose to adjust a comfortable volume and sound effect by himself through the voice control module 114, and then send a second voice control signal to the control module 113. The control module 113 adjusts the frequency and amplitude of the voice digital conversion signal according to the second voice control signal.

[0067] In one embodiment, the voice control module 114 can be a software tool, such as a software applet, etc. The subject can adjust the comfortable volume and sound effects by himself through the software tool on a device such as a tablet or a mobile phone, and then send a second voice control signal to the control module 113. The control module 113 adjusts the frequency and amplitude of the voice digital conversion signal according to the second voice control signal.

[0068] The voice digital conversion signal contains the control information of amplitude and frequency as well as the voice information transmitted by the device. After receiving the voice digital conversion signal, the digital-to-analog conversion module 120 converts the voice digital conversion signal into a voice analog signal as a voice excitation signal to drive the voice vibration module 20. The voice vibration module 20 receives the voice excitation signal and converts the voice excitation signal into a mechanical voice vibration signal. Through the voice control module 114, the subject can choose a voice suitable for him according to his own needs, and further adjust the subject's use experience, thereby increasing the human-computer interaction function between the subject and the medical device and improving the subject's use experience.

[0069] See also Figure 4 In one embodiment, the sound transmission driving module 10 further includes a digital-to-analog conversion module 120, a power amplifier module 130, and a frequency synthesis module 140. The digital-to-analog conversion module 120 is connected to the third end of the control module 113, and is used to convert the voice digital conversion signal into a voice analog signal. The power amplifier module 130 is connected to the digital-to-analog conversion module 120, and is used to amplify the voice analog signal to obtain an analog amplified signal. The frequency synthesis module 140 is connected to the power amplifier module 130, and is used to adjust the frequency of the analog amplified signal to obtain a voice excitation signal.

[0070] In the present embodiment, the digital-to-analog conversion module 120 performs digital-to-analog conversion on the voice digital conversion signal to obtain a voice analog signal. The voice analog signal, as a voice excitation signal, can be adapted to the voice vibration module 20 for excitation to generate a voice vibration signal for transmission to the subject. The digital-to-analog conversion module 120 has a low degree of distortion and can maintain the integrity and flexibility of the voice command during the conversion process. Furthermore, through the digital-to-analog conversion module 120, the analog signal corresponding to the original device-side voice information can be accurately restored, and the accurate device-side voice information can be quickly transmitted to the subject, thereby achieving effective communication between the device side and the subject.

[0071] The digital-to-analog conversion module 120 receives the amplitude and frequency control information contained in the voice digital conversion signal and the voice information transmitted by the device end. The digital-to-analog conversion module 120 converts the voice digital conversion signal into a voice analog signal. The voice analog signal also contains the amplitude and frequency control information and the voice information transmitted by the device end. The power amplifier module 130 adjusts the amplification factor according to the amplitude control information in the voice analog signal, which can increase the amplitude of the voice analog signal and obtain an analog amplified signal. Through the analog amplified signal, the vibration amplitude of the voice vibration signal can be increased, so that the vibration transmitted to the position of the ear nerve can be clearly identified by the subject, so as to make up for the loss of the voice vibration signal transmitted from different parts of the body to the ear nerve.

[0072] The analog amplified signal contains frequency control information and voice information transmitted by the device. The frequency synthesis module 140 changes the frequency according to the frequency control information in the analog amplified signal, and can adjust the frequency of the analog amplified signal to obtain a voice excitation signal. Furthermore, through the voice excitation signal, the vibration frequency of the voice vibration signal can be changed, so that the sound transmitted to the position of the ear nerve is sharper (high frequency) or rougher (low frequency). Therefore, through the power amplification module 130 and the frequency synthesis module 140, a voice simulation signal of a specified amplification factor and frequency can be generated, that is, a voice excitation signal, to drive the voice vibration module 20 to change the voice vibration signal, thereby adjusting the volume and sound effect of the voice heard by the subject.

[0073] See also Figure 5 In one embodiment, the frequency synthesis module 140 is connected to the digital-to-analog conversion module 120 to adjust the frequency of the voice analog signal to obtain a frequency adjustment signal. The power amplifier module 130 is connected to the frequency synthesis module 140 to amplify the frequency adjustment signal to obtain a voice excitation signal.

[0074] In this embodiment, the order of control of the power amplifier module 130 and the frequency synthesis module 140 can be interchanged. The frequency synthesis module 140 performs frequency adjustment on the voice simulation signal to obtain a frequency adjustment signal. The power amplifier module 130 then amplifies the frequency adjustment signal to obtain a voice excitation signal to drive the voice vibration module 20 to change the voice vibration signal, thereby adjusting the volume and sound effect of the sound heard by the testee. The relevant description of the power amplifier module 130 and the frequency synthesis module 140 can refer to the relevant description in the above embodiment.

[0075] See also Figure 6 In one embodiment, the voice vibration module 20 includes a voice conversion module 210 and a voice vibration component 220. The voice conversion module 210 is connected to the sound transmission drive module 10, and is used to convert the voice excitation signal into a vibrator drive signal, and protect the voice vibration module 20. The voice vibration component 220 is connected to the voice conversion module 210, and is used to convert the vibrator drive signal into a voice vibration signal. The voice vibration component 220 is also used to contact the body surface of the subject through a fixed component to transmit the voice vibration signal to the subject.

Voice conversion module 210 is also used for protecting voice vibration module 20, guarantees that voice vibration module 20 works normally, avoids the damage of each component in voice vibration module 20 by factors such as overload, overvoltage, overcurrent, overheating or short circuit. Voice conversion module 210 can cut off power supply in time, prevents voice vibration module 20 from burning. Through fixed assembly, voice vibration assembly 220 can be fixed on the body surface of measured person, makes voice vibration assembly 220 fully contact with the body surface of measured person, avoids the problem of falling off in signal transmission process, to ensure that the operator real-time prompt information of console equipment end or / and the fixed prompt information of equipment are accurately transmitted to measured person.

[0077] In one embodiment, the voice conversion module 210 includes a signal source, a power amplifier, a driving circuit, an overvoltage protection circuit, an overcurrent protection circuit, an overheat protection circuit, a short circuit protection circuit, etc. Through the voice conversion module 210, the accuracy and stability of the voice excitation signal can be ensured, and the precise control of the voice vibration component 220 can be achieved. In addition, the voice conversion module 210 can also ensure the safe operation of the voice vibration module 20, and can extend the service life, and improve the performance and accuracy of the contact sound transmission device 100.

[0078] Compared with the traditional technology of sending the system prompt sound and the operator's voice to the person being tested through a speaker, the contact sound transmission device 100 provided in the present application has a voice conversion module 210, which can avoid damage by factors such as overload, overvoltage, overcurrent, overheating or short circuit, thereby improving the service life and reliability.

[0079] In one embodiment, the voice vibration assembly 220 includes components such as a magnet, a coil and a vibrating membrane. When the voice vibration assembly 220 receives the vibrator drive signal, the current passes through the coil, and is subjected to the force in the magnetic field generated by the magnet, thereby generating a voice vibration signal. The voice vibration assembly 220 is in direct contact with the body of the measured person, and the voice vibration signal is conducted to the inner ear and auditory nerve of the measured person through the skin, muscles and bones, so that the measured person can clearly hear the voice of the operator or the prompt tone of the console device end.

[0080] In one embodiment, the voice conversion module 210 is further used to feed back the state signal of the voice conversion module 210 to the control module 113 in the sound transmission driving module 10. The control module 113 is used to adjust the working state of the voice vibration module 20 according to the state signal.

[0081] In the present embodiment, the voice conversion module 210 and the control module 113 can be connected by wired communication or wireless communication, and the state signal of the voice conversion module 210 is fed back to the control module 113. Then, the control module 113 can timely regulate the working state of the voice vibration module 20 according to the state signal. In one embodiment, the state signal includes state signals such as whether the power supply of the voice vibration component 220 exists, whether the voice excitation signal can be received normally, and whether the voice vibration component 220 is driven according to the amplitude and frequency in the voice excitation signal. The state signal of the voice conversion module 210 is fed back to the control module 113 in the sound transmission drive module 10, and the control module 113 can know the working condition of the voice vibration module 20 in real time. If there is an abnormal situation in the voice vibration module 20, the control module 113 can take countermeasures in time, such as cutting off the power supply of the voice vibration module 20 or sending the abnormal information of the voice vibration module 20 to the device end, so as to timely regulate the working state of the voice vibration module 20 and ensure the safe and accurate operation of the contact sound transmission device 100.

[0082] In one embodiment, the fixing component is a flexible belt structure or a magnetic structure or a bayonet bracket structure or a ring locking structure or a head beam structure or an ear hook structure.

[0083] In this embodiment, the flexible belt-like structure can be a belt-like structure formed by flexible materials such as a tape adhesive structure, a binding belt, and a wristband. Using the flexible belt-like structure as a fixed component to fix the voice vibration component 220 to the body surface of the subject can better fit the body curve, provide appropriate pressure to the subject, and achieve a comfortable wearing experience. The magnetic structure is a fixed component with magnetic properties. When the magnetic structure is used as a fixed component and adsorbed on the body surface of the subject, it will not cause sticky irritation to the skin and will not cause damage to the skin. Using the bayonet bracket structure as a fixed component can be tightly connected to the body part of the subject to provide more stable support. At the same time, there is no need to wrap the subject, and there is a heat dissipation gap, which is conducive to heat dissipation during wearing.

[0084] See also Figure 7 , the fixed component can be an annular locking structure 60. The circumferential opposite ends of the annular locking structure 60 are connected to the housing of the voice vibration module 20. The annular locking structure 60 forms an open accommodation space, and the arms, legs, and neck of the measured person can be placed in the open accommodation space. The annular locking structure 60 is used as a fixed component, and is stuck with the arms, legs, neck or head to ensure that the voice vibration component 220 is in full contact with the body of the measured person. The annular locking structure 60 is an annular structure, which can fit 360 degrees with the arms, legs, neck and other parts of the measured person, and can be tightly surrounded around the body parts, so that the voice vibration component 220 is firmly fitted with the body surface of the measured person. At the same time, the annular locking structure 60 makes the arms, legs, neck and other parts of the measured person evenly stressed, providing a better wearing experience.

[0085] Using the head beam structure as a fixed component can better span the subject's head without affecting the subject's limb movement, thus avoiding the subject's muscle fatigue caused by wearing it on the arms, legs, neck, etc. Using the ear hook structure as a fixed component can achieve contact between the voice vibration component 220 and the subject's head, making it difficult for the voice vibration component 220 to fall off and can move with the subject without being affected.

[0086] By fixing the position and fixing method of the voice vibration component 220 and the subject provided in the present application, and contacting with the subject, it can be applicable to all groups of subjects, so that the contact sound transmission device 100 has strong adaptability and is easy to operate.

[0087] In one embodiment, the sound transmission driving module 10 is disposed in the examination bed 201 of the medical device 200. The sound transmission driving module 10 is connected to the voice vibration module 20 through a shielded cable. The sound transmission driving module 10 and the voice vibration module 20 are made of shielding material.

[0088] In this embodiment, the sound transmission drive module 10 can be arranged in the bed base or mattress of the examination bed 201, and will not be affected by the external environment humidity, dust and other impurities, which can increase the service life of the sound transmission drive module 10. The sound transmission drive module 10 is installed in the examination bed 201, and it is convenient to check, test and replace, which is conducive to the maintenance of the sound transmission drive module 10 in the later stage.

[0089] The sound transmission driving module 10 is connected to the voice vibration module 20 through a shielded cable, and transmits power and communication signals to the voice vibration module 20, so that the voice vibration module 20 completes the corresponding vibration action and feeds back the status signal to the sound transmission driving module 10. The sound transmission driving module 10, the voice vibration module 20 and the connecting cable are all made of shielding materials, so that the contact sound transmission device 100 is not easily affected by external electromagnetic compatibility (EMC) interference.

[0090] In one embodiment, the shielding materials used in the sound transmission drive module 10, the voice vibration module 20 and the connecting cables can be one or more of metal materials (for example: steel plates, aluminum plates, copper foils and copper meshes, etc.), magnetic materials (for example: ferrites, nanocrystalline materials, etc.), conductive rubbers, conductive foams and conductive fiber cloths. In one embodiment, the voice vibration module 20 also includes a vibration power supply module 230. The vibration power supply module 230 is connected to the voice conversion module 210 to provide the electrical energy required by the voice conversion module 210. The sound transmission drive module 10 is arranged in the frame 202 of the medical device 200. The voice conversion module 210 is connected to the sound transmission drive module 10 via wireless communication.

[0091] In the present embodiment, for application scenarios with complex electromagnetic field environments, such as nuclear magnetic medical equipment, the sound transmission drive module 10 communicates with the voice vibration module 20 through wireless transmission, such as Bluetooth communication, infrared communication or 5G communication, and is not easily affected by EMC interference. The voice vibration module 20 is powered by its own vibration power supply module 230. The vibration power supply module 230 can be a battery. The voice conversion module 210 includes a wireless communication module for receiving the voice excitation signal of the sound transmission drive module 10, and outputting a voice vibration signal according to the voice excitation signal, so that the measured person can clearly and accurately know the operator's real-time prompt information or / and the fixed prompt information of the device conveyed to the measured person by the device operator at the console. The working status signal of the voice vibration module 20 can also be fed back to the sound transmission drive module 10 through wireless transmission. Thus, the voice conversion module 210 is connected to the sound transmission drive module 10 through wireless communication.

[0092] The frame 202 of the medical device 200 has good electromagnetic shielding performance. The sound transmission drive module 10 is arranged in the frame 202 of the medical device 200, effectively blocking external electromagnetic radiation and avoiding interference from the external electromagnetic environment. Furthermore, the sound transmission drive module 10 is arranged in the frame 202 of the medical device 200, which also reduces the impact of impurities such as dust on the performance of components and prolongs the service life of the components.

[0093] See also Figure 8 In one embodiment, the contact sound transmission device 100 further includes an active noise reduction module 30. The active noise reduction module 30 is used to convert the ambient noise signal into a noise reverse audio signal. The active noise reduction module 30 is connected to the sound transmission driving module 10 and is used to send the noise reverse audio signal to the sound transmission driving module 10.

[0094] In this embodiment, the sound collection device on the medical device (which can also be understood as a device for collecting sound such as a microphone) is used to collect noise sound waves in the surrounding environment to form an environmental noise signal. The active noise reduction module 30 receives the environmental noise signal and converts the environmental noise signal into a noise reverse audio signal. The noise reverse audio signal can be understood as a current signal of the reverse noise sound wave. The noise reverse audio signal is transmitted to the voice vibration module 20 through the sound transmission drive module 10, so that the voice vibration component 220 sends a corresponding voice vibration signal to neutralize and eliminate the environmental noise in the voice command, so that the subject can hear a clearer and more accurate sound.

[0095] Through the active noise reduction module 30, the contact sound transmission device 100 has an active noise reduction function, which can reduce the interference of environmental noise on the subject. Furthermore, the active noise reduction module 30 can also eliminate the inherent factors of the subject's own hearing loss, and conveniently and quickly give the subject clear and accurate prompt information. Therefore, the subject can make corresponding inspection actions based on the clear and accurate prompt information.

[0096] See also Fig. 9 In one embodiment, the active noise reduction module 30 includes a reverse processing module 310, a compensation module 320 and a dynamic equalization module 330. The reverse processing module 310 is used to filter, delay and phase shift the ambient noise signal to obtain a reverse signal. The compensation module 320 is connected to the reverse processing module 310, and is used to perform compensation processing on the reverse signal to obtain a reverse compensation signal. The dynamic equalization module 330 is connected to the compensation module 320, and is used to perform dynamic equalization processing on the reverse compensation signal to obtain a noise reverse audio signal. The dynamic equalization module 330 is connected to the sound transmission drive module 10, and is used to send the noise reverse audio signal to the sound transmission drive module 10.

[0097] See also Fig.10The reverse processing module 310 includes a filtering module 311, a delay module 312 and a phase shift module 313, which can filter, delay and phase shift the environmental noise signal to obtain a reverse signal, such as Fig. 9 As shown. The filter module 311 filters out the clutter signal in the environmental noise signal and retains the main frequency interference signal. The reverse signal is obtained through the delay module 312 and the phase shift module 313. The reverse signal passes through the compensation module 320 and the dynamic equalization module 330 to generate a current signal of a noise sound wave with an amplitude opposite to the main frequency band, that is, a noise reverse audio signal, to neutralize the impact of the environmental noise on the subject.

[0098] By processing the environmental noise signal through the reverse processing module 310, the compensation module 320 and the dynamic equalization module 330, a noise reverse audio signal can be obtained, which can reduce the impact of the environmental noise on the subject and improve the comfort during the examination. When there is a high decibel noise during the scanning of the medical device (such as nuclear magnetic noise or CT rotation noise), the contact sound transmission device 100 can achieve active noise reduction, so that the subject can block the noise and can clearly hear the fixed prompt sound of the device at the console device end or / and the real-time voice of the device operator, and then can accurately know the fixed prompt information of the device at the console device end or / and the real-time prompt information of the operator, so that the subject can make corresponding inspection actions.

[0099] See also Fig.11 In one embodiment, the contact sound transmission device 100 further includes a noise error processing module 40. The first end of the noise error processing module 40 is connected to the dynamic equalization module 330, and is used to obtain an error adjustment signal according to the noise reverse audio signal and the ambient noise signal. The second end of the noise error processing module 40 is connected to the compensation module 320, and is used to send the error adjustment signal to the compensation module 320. The compensation module 320 is also used to perform compensation processing on the reverse signal according to the error adjustment signal to obtain an error-adjusted reverse compensation signal. The dynamic equalization module 330 is also used to perform dynamic equalization processing on the error-adjusted reverse compensation signal to obtain an error-adjusted noise reverse audio signal, and send the error-adjusted noise reverse audio signal to the sound transmission driving module 10.

[0100] In this embodiment, the noise error processing module 40 compares the ambient noise signal collected by the microphone with the noise reverse audio signal processed by the active noise reduction module 30 to obtain an error adjustment signal. The error adjustment signal characterizes the difference between the ambient noise signal and the noise reverse audio signal. If there is a difference between the ambient noise signal and the noise reverse audio signal, the error adjustment signal is fed back to the compensation module 320 of the active noise reduction module 30. Then, the compensation module 320 of the active noise reduction module 30 further compensates the reverse signal again according to the error adjustment signal to obtain the error-adjusted reverse compensation signal. Further, the error-adjusted reverse compensation signal is transmitted to the dynamic equalization module 330. The dynamic equalization module 330 performs dynamic equalization adjustment on the error-adjusted reverse compensation signal to obtain the error-adjusted noise reverse audio signal. Thus, the error-adjusted noise reverse audio signal is sent to the sound transmission drive module 10, and passes through the voice vibration module 20, so that the voice vibration component 220 sends a corresponding voice vibration signal to neutralize and eliminate the ambient noise in the voice command, so that the subject can hear a clearer and more accurate sound.

[0101] Therefore, the ambient noise signal and the noise reverse audio signal are compared by the noise error processing module 40 to obtain an error adjustment signal, and the error adjustment signal is fed back to the active noise reduction module 30. Based on the error adjustment signal, the compensation module 320 and the dynamic equalization module 330 of the active noise reduction module 30 adjust the amplitude and frequency of the signal, re-equalize the noise reverse audio signal, and send the obtained error-adjusted noise reverse audio signal to the sound transmission driving module 10 to achieve a perfect neutralization effect, so that the subject can hear a clearer and more accurate sound.

[0102] In one embodiment, the noise error processing module 40 may be a noise error processor.
