[0002] Total laryngectomy is the main means for treating advanced laryngeal cancer. However, after the operation, patients lose the vocal cord vibration function and need to rely on auxiliary sound - generating devices to restore their language ability. Currently, the widely used wearable electronic larynx in clinical practice mainly collects pronunciation signals through a neck - contact vibration sensor and outputs speech after conversion by electronic components.

[0003] Total laryngectomy patients need to rely on auxiliary sound - generating devices such as electronic larynx to restore their speech function. Existing wearable electronic larynges generally have the problem of inaccurate pronunciation point positioning. Traditional devices use fixed structures or manual adjustment of sensors, which are difficult to adapt to the anatomical differences of patients' necks and tissue deformation after surgery, resulting in inaccurate vibration signal acquisition. In addition, the voice of traditional electronic larynges is mechanically prominent, unable to restore the personalized voiceprint characteristics of patients, and the output speech presents a single electronic tone color, making the clarity and emotional expression effect of the voice poor. Clinical research shows that existing wearable electronic larynges cannot meet the usage needs of most patients.

[0004] Therefore, it is very necessary to study a wearable auxiliary sound - generating device and a sound - generating method for total laryngectomy patients that can adjust the position of the acquisition mechanism to accurately fit the pronunciation point and restore the personalized voiceprint characteristics of patients through AI voice - changing technology.

[0042] Embodiment 1

[0043] Please refer to Figures 1 to 9 As shown, a wearable auxiliary voice - generating device for total laryngectomy patients includes: a housing 1 for support, a positioning mechanism 2 for adjusting the position of the acquisition mechanism 3, an acquisition mechanism 3 for acquiring vibration signals at the voice - generating point on the patient's neck, a voice - generating mechanism 4 for generating sound, and a control device 5 for controlling the positioning mechanism 2, the acquisition mechanism 3, and the voice - generating mechanism 4.

[0044] The housing 1 includes a first housing 11, a second housing 12, a third housing 13, and a fourth housing 14. The first housing 11, the second housing 12, the third housing 13, and the fourth housing 14 are fixedly connected in sequence. A first connection groove 131 and a strap 132 are further provided on the third housing 13. It can be understood that the device can be worn on the patient's neck through the strap 132. Preferably, by tightening the strap 132, the housing 1 can be closely attached to the patient's neck, and by loosening the strap 132, the housing 1 can be separated from the patient's neck or the device can be removed from the neck. A power supply compartment 143 is provided at the bottom of the fourth housing 14, that is, the power supply is fixedly installed in the power supply compartment 143.

[0045] The positioning mechanism 2 includes a lifting component 21 and a rotating component 22. The lifting component 21 is slidably disposed in the third housing 13. Specifically, the lifting component 21 includes a lifting bracket 211, an arc-shaped chute 212, and a rack 213. The lifting bracket 211 is slidably engaged with the inner walls of the second housing 12 and the third housing 13. It can be understood that the lifting bracket 211 can move between the second housing 12 and the third housing 13. The arc-shaped chute 212 is disposed on the lifting bracket 211, and the rack 213 is disposed on the upper end surface of the lifting bracket 211. The rotating component 22 is installed above the lifting component 21. Specifically, the rotating component 22 includes a rotating bracket 221, two side plates 222, a first driving motor 224, a lead screw 225, and a second driving motor 226. The rotating bracket 221 is slidably disposed in the arc-shaped chute 212. It can be understood that the rotating bracket 221 can slide along the arc-shaped chute 212 on the lifting component 21. The two side plates 222 are fixedly disposed on the upper end surface of the rotating bracket 221. The first driving motor 224 is fixedly connected to the rotating bracket 221, and the lead screw 225 is connected to the rotating shaft of the first driving motor 224, that is, the first driving motor 224 can drive the lead screw 225 to rotate. The second driving motor 226 is fixed on the rotating bracket 221, and the second driving motor 226 is engaged with the rack 213 through a gear. It can be understood that the rotation of the second driving motor 226 can drive the rotating bracket 221 to slide along the arc-shaped chute 212 on the lifting bracket 211 through the cooperation of the gear and the rack 213. Furthermore, the rotating component 22 can drive the acquisition mechanism 3 to rotate and adjust the position of the acquisition mechanism 3.

[0046] The acquisition mechanism 3 is installed on the rotating assembly 22, and the acquisition mechanism 3 contacts the sound-producing point on the patient's neck to acquire the vibration information of the patient's neck. Specifically, the acquisition mechanism 3 includes a sliding bracket 31, a vibration conduction film 32, and a contact head 33. The sliding bracket 31 is slidably arranged between two side plates 222, and the sliding bracket 31 is matched with the lead screw 225. It can be understood that when the first drive motor 224 drives the lead screw 225 to rotate, the acquisition mechanism 3 can be driven to slide between the two side plates 222, thereby adjusting the distance between the acquisition mechanism 3 and the patient's neck. An electromagnet 312 is arranged on the sliding bracket 31, and the vibration conduction film 32 is fixedly arranged on the sliding bracket 31. The contact head 33 includes a sliding rod 331 and a permanent magnet 332. The sliding rod 331 is slidably matched with the sliding bracket 31. Correspondingly, the sliding bracket 31 is made of iron, and the permanent magnet 332 can adsorb the sliding bracket 31. The electromagnet 312 is matched with the permanent magnet 332. After the electromagnet 312 is energized, it generates a magnetic force, and the electromagnet 312 and the permanent magnet 332 repel each other, thereby pushing at least a part of the contact head 33 out of the limit groove 311. Specifically, a limit groove 311 is arranged on the sliding bracket 31, and the limit groove 311 is matched with the contact head 33. It can be understood that when the electromagnet 312 is not energized, the permanent magnet 332 and the sliding bracket 31 attract each other, thereby driving the contact head 33 to slide towards the vibration conduction film 32, so that the contact head 33 retracts to the position of the limit groove 311. The sliding rod 331 is connected to the vibration conduction film 32. After contacting the sound-producing point on the patient's neck, when the patient makes a sound, the sound-producing point vibrates, and is transmitted to the vibration conduction film 32 through the contact head 33 and the sliding rod 331, and the vibration conduction film 32 generates an electrical signal and transmits it to the control device 5.

[0047] The sound-producing mechanism 4 and the control device 5 are fixedly installed on the first housing 11. Specifically, the sound-producing mechanism 4 includes a loudspeaker 41, and the loudspeaker 41 is fixedly installed on the first housing 11.

[0048] Specifically, an air cavity 121 and a sound guide pipe orifice 122 are arranged on the second housing 12. The air cavity 121 is in extrusion fit with the rotating assembly 22, and a sealed cavity is formed between the air cavity 121 and the rotating assembly 22. The sound guide pipe orifice 122 is connected to the sound guide pipe.

[0049] Correspondingly, the fourth housing 14 further includes a second connection groove 141 and a handle 142. The second connection groove 141 is arranged at the bottom of the fourth housing 14, and the handle 142 is hinged at the second connection groove 141. When the handle 142 is turned upwards, it passes through the first connection groove 131 and cooperates with the bottom of the positioning mechanism 2.

[0050] It can be understood that when the patient's neck skin has not fully recovered after surgery, the strap 132 can be loosened to separate the outer shell 1 from the patient's neck, or the device can be removed from the neck. Then, the electromagnet 312 is energized, and the contact 33 of the acquisition mechanism 3 extends from the sliding bracket 31. After that, the handle 142 is toggled to push the positioning mechanism 2 and the acquisition mechanism 3 installed at the upper end of the positioning mechanism 2 from the third outer shell 13 into the second outer shell 12, forming a sealed cavity between the air cavity 121 and the rotating assembly 22. The sound guide nozzle 122 is connected to the sound guide tube, and the patient can put the sound guide tube into the mouth to drive the contact 33 to move through the sound guide tube, thereby generating a vibration signal and transmitting it to the control device 5.

[0051] The control device 5 includes a positioning controller 51, an AI voice conversion module 52, and an antenna 53. The positioning controller 51 is electrically connected to the positioning mechanism 2, and the AI voice conversion module 52 is electrically connected to the antenna 53, the acquisition mechanism 3, and the antenna 53.

[0052] The working principle of the present invention is as follows:

[0053] Before surgery, the patient's voice is recorded, and the voice is processed to obtain the patient's voiceprint information, which is then sent to the AI voice conversion module 52 through the antenna 53.

[0054] When the patient's neck skin has not fully recovered after surgery, the strap 132 can be loosened to separate the outer shell 1 from the patient's neck, or the device can be removed from the neck. Then, the electromagnet 312 is energized, and the contact 33 of the acquisition mechanism 3 extends from the sliding bracket 31. After that, the handle 142 is toggled to push the positioning mechanism 2 and the acquisition mechanism 3 installed at the upper end of the positioning mechanism 2 from the third outer shell 13 into the second outer shell 12, forming a sealed cavity between the air cavity 121 and the rotating assembly 22. The sound guide nozzle 122 is connected to the sound guide tube, and the patient can put the sound guide tube into the mouth to drive the contact 33 to move through the sound guide tube, thereby generating a vibration signal and transmitting it to the control device 5. The AI voice conversion module 52 of the control device 5 processes the vibration signal, and then plays the processed voice through the control speaker 41.

[0055] After the neck skin has fully recovered after the operation, when using it for the first time, by tightening the strap 132, the outer shell 1 can be made to closely adhere to the patient's neck. The positioning controller 51 is used to control the positioning mechanism 2 to adjust the position of the acquisition mechanism 3 so that it can be attached to the vocalization point on the patient's neck. The positioning controller 51 records the position information of the positioning mechanism 2. The acquisition mechanism 3 acquires the vibration signal of the vocalization point on the patient's neck. The AI voice conversion module 52 of the control device 5 processes the vibration signal, and then the processed voice is played through the control speaker 41. When the patient temporarily stops using the device, the strap 132 can be loosened to separate the outer shell 1 from the patient's neck, or the device can be removed from the neck, and the positioning controller 51 is used to control the positioning mechanism 2 to reset to prevent damage to the acquisition mechanism 3. When using it again, by tightening the strap 132, the outer shell 1 can be made to closely adhere to the patient's neck. By restoring the position recorded during the first use through the positioning controller 51, the device can be used to produce sound.
