Damage to the voice will directly affect a person's ability to express himself and even affect communication between people. It is reported that with the increasing frequency of social communication, the incidence of voice diseases has increased year by year, accounting for about 5%-10% of ENT diseases, of which about 30% of people have unhealthy voice problems, which has also attracted people's attention to voice disorders. Early detection of voice lesions can minimize the patient's pain and economic burden.

[0003] Currently, a detection device is needed for voice detection and analysis. Existing detection devices are mostly wearable when collecting vocal information. Therefore, they are easily affected by wearing specifications or environmental factors in actual detection, which often leads to poor clarity of the collected voice, thereby reducing the credibility of the detection and evaluation device. Utility Model Content

[0004] The utility model provides a detection device for pathological voice, which can shield external noise and guide the patient to open the chest cavity and maintain a correct and standard pronunciation posture, so as to make the voice clearer and louder and improve the collection quality of the voice.

[0009] The utility model has the beneficial effects that: during the voice detection process, the detection room provides a relatively quiet test environment for the patient, and the distance between the patient and the sound pickup device during the detection process is limited by the positioning seat, and the patient's sitting posture is limited by the positioning plate to ensure correct phonation, and the tester issues action instructions to the patient in the detection room through the detection computer control prompt screen, and the patient emits corresponding sounds according to the instructions, and the sound pickup device sends the collected sound signal to the detection computer, and the tester analyzes the patient's voice through the computer to obtain the basis for disease judgment, so the detection room can be used to shield external noise, and guide the patient to open the chest cavity and maintain a correct and standard pronunciation posture, so that the sound is clearer and louder, and the quality of voice collection is improved. When the set screw is loosened, the height of the positioning plate can be adjusted, so that not only the patient's chest position is limited, but also the patient's head is limited to tilt forward through the top of the positioning plate, so as to ensure a good throat pronunciation posture, and the handle is conducive to the patient opening the chest cavity and facilitating the patient's phonation. The soundproof board has a two-way soundproofing effect inside and outside. During the patient's voice collection process, the sound waves are transmitted to the two-way soundproof cotton through the sound-permeable hole, thereby eliminating the internal noise and minimizing the echo interference in the test room. The combination of one-way soundproof cotton and two-way soundproof cotton reduces the noise outside the test room from entering the test room, thus ensuring the quiet effect in the test room. The sound pickup device adjusts the height position through the cooperation of the slider and the slideway, and adapts to the patient's voice direction with the pitch angle of the sound-absorbing screen, thereby improving the quality of the patient's voice collection.

[0017] according to Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a detection device for pathological voice comprises: a detection room 1, which is a cabin structure, and a swing door 2 is provided on one side of the detection room 1, and the top and four walls of the detection room 1, as well as the swing door 2 are all composed of sound insulation panels; a positioning seat 3, which is fixedly arranged on one side of the detection room 1, and a positioning plate 4 is provided on the front of the positioning seat 3; a sound pickup device 22 and a prompt screen 5, which are both arranged on the side of the detection room 1 opposite to the positioning seat 3, and a through wire channel 6 is provided on the side wall of the detection room 1 corresponding to the sound pickup device 22, and the signal lines of the sound pickup device 22 and the prompt screen 5 extend outward through the wire channel 6; a detection computer, which is arranged outside the detection room 1, and each of the signal lines is electrically connected to the detection computer respectively.

[0018] Through the above settings, during the voice detection process, the detection room 1 provides a relatively quiet test environment for the patient, and the distance between the patient and the sound pickup device 22 during the detection process is limited by the positioning seat 3, and the patient's sitting posture is limited by the positioning plate 4 to ensure correct voice production. The tester issues action instructions to the patient in the detection room 1 through the detection computer control prompt screen 5, and the patient makes corresponding sounds according to the instructions. The sound pickup device 22 sends the collected sound signal to the detection computer, and the tester analyzes the patient's voice through the computer to obtain the basis for judging the condition. Through this setting, the detection room 1 shields external noise as much as possible, and guides the patient to open the chest and maintain a correct and standard pronunciation posture, so that the sound is clearer and louder, and the quality of voice collection is improved.

[0019] In order to ensure the environmental comfort in the testing room 1, the corresponding testing room 1 is equipped with lighting and ventilation devices. It should be noted that the ventilation device is in a closed state during the test to reduce the impact of wind noise on sound collection. In addition, a camera is installed in the testing room 1 to facilitate the experimenter to check the patient's condition and provide guidance and help.

[0020] The positioning seat 3 includes a seat cushion 7, a pair of positioning brackets 8 are fixedly provided at the bottom of the seat cushion 7, the positioning brackets 8 extend upward in front of the seat cushion 7, the positioning plate 4 is slidably matched with the positioning bracket 8 through a sliding sleeve 9, and the sliding sleeve 9 is provided with a fixing screw; a pair of limiting brackets 10 are provided in the middle of the positioning bracket 8, the limiting brackets 10 extend horizontally in the direction away from the positioning plate 4, and the free ends of each limiting bracket 10 are vertically connected to an operating handle 11, and the operating handle 11 is electrically connected to the prompt screen 5.

[0021] In this setting, after loosening the set screw, the height of the positioning plate 4 can be adjusted, thereby not only limiting the position of the patient's chest, but also limiting the forward tilt of the patient's head through the top of the positioning plate 4, thereby ensuring a good laryngeal pronunciation posture, while the handle helps the patient to open his chest and speak.

[0023] In this setting, the sound insulation board has a two-way sound insulation effect inside and outside. During the patient's voice collection process, the sound waves are transmitted to the two-way sound insulation cotton 14 through the sound-transmitting hole 16, thereby eliminating the internal noise and reducing the echo interference in the detection room 1 as much as possible. The combination of the unidirectional sound insulation cotton 15 and the two-way sound insulation cotton 14 reduces the noise outside the detection room 1 from being transmitted into the detection room 1, thereby ensuring the quiet effect in the detection room 1.

[0024] The sound pickup device 22 includes a slide 17 vertically arranged on the inner wall of the detection chamber 1, and a slider 18 cooperating with the slide 17; it also includes a sound-absorbing screen 19 and a microphone 20.

[0025] In this configuration, the sound pickup device 22 is adjusted in height by the cooperation of the slider 18 and the slide 17, and is adapted to the patient's vocal direction by the pitch angle of the sound absorbing screen 19, thereby improving the quality of collecting the patient's voice.

[0026] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
