[0002] At present, ear canal examinations include items such as hearing examinations, otoscope examinations, and CT examinations. The instruments used include various tools such as illumination lights, Wood's lamps, otoscopes, and ear picks. In order to facilitate the replacement of these different tools for use and quickly connect to the power supply, people usually use a coupler, which connects the power cord through a coupling cavity that is adapted to the bottom of each tool. In this way, corresponding detection heads can be replaced according to different project requirements. However, in ear canal examinations, the hearing detection and feedback of the examinee are often crucial. When replacing these tools for examinations, usually only the examiner judges the disease by observation based on experience, and it is impossible to immediately conduct hearing examinations and sound collection. Often, the instruments in hand are stopped, and other tools such as tuning forks are used for a rough hearing examination. As a result, it is difficult to distinguish whether the real blockage or lesion affects hearing, and often other more comprehensive examinations are required to obtain the results.

[0019] In the description of the present utility model, it should be noted that unless otherwise clearly defined and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations. The technical solutions of the present utility model will be further described below with reference to the accompanying drawings and embodiments.

[0020] As Figures 1 - 3As shown in the figure, a coupler with sound collection and output functions according to the present utility model includes a socket 2, a connector 3, and a coupling cavity 4 that are sequentially connected to a wire 1. A fixing seat 5 is provided inside the connector 3. A circuit board 6, a sound collection module 7, and a sound output module 8 are respectively provided on the fixing seat 5. The sound collection module 7 is used to convert the collected sound into an electrical signal, and the sound output module 8 is used to play the sound required during ear detection. The circuit board 6 is electrically connected to the sound collection module 7, the sound output module 8, and the socket 2 respectively. The sound collection module 7 and the sound output module 8 are also electrically connected to the coupling cavity 4 through metal sheets 9 respectively. By adding a sound collection module 7 and a sound output module 8, such as components like speakers and microphones, at the bottom of the coupling cavity 4, the present utility model can better collect and output sound. While using relevant instruments to deeply examine and inspect the ear canal, basic detections such as hearing can be quickly carried out without replacing other instruments such as tuning forks, which is convenient for the judgment of diseases. The present utility model combines the use of the sound collection module 7 and the sound output module 8. During detection, through the circuit control system preset on the circuit board 6, that is, the PCB board, this circuit connection is a conventional circuit control. The sound output module 8 emits a suitable detection sound effect and plays it directly beside the person being examined, forming sound wave conduction or bone conduction in the ear canal. According to the feedback of the person being examined, the detection result can be quickly obtained. Or the volume can also be adjusted, and the sound collection module 7 is used to receive the signal after the sound wave is reflected from the ear canal and convert it into an electrical signal. After analysis, it can be found whether there are situations such as unclear volume discrimination or blockages. Usually, after connecting different tools for deepening into the ear canal to the coupling cavity 4, the output and collection detection of sound can be synchronized with operations such as pressing and dredging, which is convenient for improving the efficiency of ear canal examination.

[0021] In one of the embodiments, first grooves 51 adapted to the sound collection module 7 and the sound output module 8 are respectively provided inside the fixing seat 5, and a second groove 52 adapted to the circuit board 6 is provided at the bottom of the fixing seat 5. The bottom of the first groove 51 is communicated with the second groove 52. The fixing seat 5 is provided to position and install the circuit board 6, the sound collection module 7, and the sound output module 8, so that the circuit board 6, the sound collection module 7, and the sound output module 8 are respectively embedded in the fixing seat 5, which is convenient for providing anti-collision protection for these delicate electronic components. At the same time, the first groove 51 is communicated with the second groove 52, allowing the sound collection module 7 and the sound output module 8 to be stably connected to the circuit board 6 through wires.

[0022] Furthermore, in order to avoid short circuit and other phenomena between the sound collection module 7 and the sound output module 8, a gasket 10 is also provided between the sound collection module 7 and the sound output module 8 and the metal sheet 9, and a through hole is provided on the gasket 10 to match the top interface of the sound collection module 7 and the sound output module 8, and the gasket 10 is made of insulating material. The gasket 10 can be made of a silicone sheet, which has a certain elasticity, so that the metal sheet can be pressed tightly on the sound collection module 7 and the sound output module 8. At the same time, its insulating effect makes the top interface of the adjacent sound collection module 7 and the sound output module 8 electrically connected to the metal sheet 9 through the through hole separately, and will not cause short circuit by cross-wires, so as to facilitate electrical connection with the electronic component part of the coupling cavity 4. At the same time, corresponding through holes can also be opened on the metal sheet 9 to facilitate the connection and positioning with the sound collection module 7 and the sound output module 8, and avoid displacement caused by vibration during use.

[0023] In addition, both ends of the connector 3 are provided with internal threads and are respectively used for threaded connection with the socket 2 and the coupling cavity 4. The metal sheet 9 is located on the fixed seat 5 at one end close to the coupling cavity 4, and the outer diameter of the metal sheet 9 is larger than the inner diameter of the coupling cavity 4. As a component added between the socket 2 and the coupling cavity 4, the connector 3 generally adopts a threaded connection fixing method. Moreover, the socket 2 and the coupling cavity 4 are external threads. After installation, the end of the connector 3 can be used to position the fixed seat 5 sleeved in the connector 3, so that the internal electrical connection is not easy to disconnect. The metal sheet 9 is equivalent to enlarging the contact surface of the electrical connection with the coupling cavity 4 after the sound collection module 7 and the sound output module 8 are added, so as to facilitate its circuit layout, and the metal sheet 9 is pressed on the fixed seat 5 by one end of the coupling cavity 4, and cooperates with the above-mentioned gasket 10, so that the various components of the device are more tightly connected and not easily disconnected due to vibration and the like. A limiting boss 11 is provided at one end of the connector 3 corresponding to the fixing seat 5 close to the socket 2, and the other side of the limiting boss 11 contacts the panel of the socket 2. Similarly, the limiting boss 11 cooperates with the end of the coupling cavity 4 to position the fixing seat 5 in the connector 3, and at the same time, it is also used to position the threaded connection between the connector 3 and the socket 2, so that the plug position on the socket 2 can be just connected to the circuit board 6. The socket 2 can adopt an aviation socket, which is a circular connector in shape, easy to cooperate with the coupler, and has pressure resistance and flame retardancy. Furthermore, the outer diameter of the circuit board 6 is larger than the inner diameter of the limiting boss 11. The circuit board 6 is embedded in the bottom of the fixing seat 5, and cooperates with the limiting boss 11 to prevent it from shifting, thereby protecting the stability of the circuit.
