[0002] Otoacoustic screening devices are mostly used for newborn hearing screening, conditioned orientation reflex testing in infants and young children, or hearing testing for children and adults. They typically consist of a main unit, accessories, probes, probe protection holders, batteries, and standard earplug kits. Currently available otoacoustic screening devices have strong anti-interference capabilities and can efficiently screen hearing. However, for ease of use, the main unit is lightweight and includes a built-in battery. The earphone probe is usually wired to the main unit, allowing for use without a power cord. This means that when the battery needs charging, the main unit requires more cables, making normal use less convenient. Furthermore, the earphone probe cannot be moved far from the main unit, which limits its application range. Therefore, it is necessary to develop a wireless charging base. By simply adding a wireless charging device to existing otoacoustic screening devices, it can be compatible with most current otoacoustic screening device main units for wireless charging and can be used with wireless earphones for hearing screening.

To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can be described as the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0019] like Figures 1-3As shown, the present invention discloses a wirelessly rechargeable ear-acoustic screening device base, including a charging base 1. The charging base 1 is generally in the shape of a right trapezoid. A power cord 11 is provided on the rear side of the charging base 1. A groove 12 is provided on the front inclined surface of the charging base 1. The groove 12 is adapted to the ear-acoustic screening device 2. A trigger switch 13 is provided in the groove 12. An induction coil 14 for wirelessly charging the ear-acoustic screening device 2 is provided in the charging base 1 at the position corresponding to the trigger switch 13. The induction coil 14 is connected in series with the trigger switch 13 and electrically connected to the power cord 11. A socket 15 is also provided at the bottom of the groove 12 corresponding to the ear-acoustic screening device 2. A signal transmitter 16 is provided in the charging base 1 and is connected in parallel to the power cord 11. The ear-acoustic screening device 2 can be electrically connected to the signal transmitter 16 through the socket 15, so that the signal receiver of the earphone 3 can be wirelessly connected to the signal transmitter 16. This invention optimizes the wireless charging function of the otoacoustic screening instrument 2. It can be universally used simply by adding a wireless charging device to the existing otoacoustic screening instrument 2. The otoacoustic screening instrument 2 is placed in the groove 12, and the induction coil 14 can wirelessly charge the otoacoustic screening instrument 2. During charging, the sound signal of the otoacoustic screening instrument 2 is transmitted to the signal transmitter 16 of the charging base 1 through the socket 15. This can change the wired connection between the earphone 3 probe and the otoacoustic screening instrument 2 to a wireless connection between the earphone 3 and the charging base 1. There is no need to change the original structure of the otoacoustic screening instrument 2. The sound signal of the otoacoustic screening instrument 2 is first transmitted to the charging base 1 through the socket 15, and then the signal transmitter 16 of the charging base 1 transmits wirelessly to the earphone 3 probe. This allows the earphone 3 to be detached from the otoacoustic screening instrument 2 and reduces the tangling of wires, making it convenient for continued use of otoacoustic screening.

[0020] Furthermore, the groove 12 is open on the top side corresponding to the charging base 1, and the two sides of the groove 12 are recessed inward to form a sliding groove. The two sides of the otoacoustic screening device 2 are provided with protrusions 21 that are adapted to the groove 12. When the otoacoustic screening device 2 is inserted into the groove 12, the front of the otoacoustic screening device 2 is higher than the front slope of the charging base 1. The shape of the groove 12 has a large capacity, which can accommodate most otoacoustic screening devices 2 and make them stable. Moreover, the sliding grooves on both sides of the groove 12 can stably insert the otoacoustic screening device 2, so that the induction coil 14 corresponds to it to realize wireless charging. The front of the otoacoustic screening device 2 protrudes, and with the adjustment button 22 and the corresponding screen on the front of the otoacoustic screening device 2, it is convenient to continue to operate the otoacoustic screening device 2 during use.

[0021] In one embodiment, the protrusions 21 are connected to both sides of the otoacoustic screening device 2 via elastic elements. When the elastic elements are compressed, the protrusions 21 are flush with the sides of the otoacoustic screening device 2. The outer shell of the otoacoustic screening device 2 can be redesigned to fit the width of the groove 12, or a shell with protrusions 21 on both sides can be fixedly fitted to fit the groove 12. The protrusions 21 allow the otoacoustic screening device 2 to be inserted into the groove 12 from top to bottom. Alternatively, by compressing the internal elastic elements, such as springs, the protrusions 21 can be retracted to be flush with the sides, allowing it to be directly inserted into the groove 12 from the front. The elastic elements are then released, lifting the protrusions 21 and locking the sides of the groove 12. This makes the otoacoustic screening device 2 more stable during charging and prevents problems such as misalignment of the induction coil 14.

[0022] Specifically, the activation of the induction coil 14 can be triggered by the trigger switch 13. When the otoacoustic screening device 2 is placed in the groove 12, due to the tight fit with the groove 12, the trigger switch 13 can be a push-button switch, pressed and triggered by the otoacoustic screening device 2. The trigger switch 13 can also be an inductive switch, thus adapting to other otoacoustic screening devices 2 of different shapes. The wireless connection between the signal receiver of the earphone 3 and the signal transmitter 16 can be Bluetooth, NFC, or Wi-Fi, ensuring network security and stability. In addition, the top side of the otoacoustic screening device 2 is provided with a jack 23 for wired connection with the earphone 3. The otoacoustic screening device 2 can be provided with two interfaces for wired connection with the earphone 3. One of them can be used with the socket 15 during charging to transmit electrical signals to the charging base 1, and then the signal transmitter 16 can realize the wireless connection with the earphone 3 probe. The other interface is the jack 23 on the top side, which, apart from being relatively far from the groove 12, serves as a backup interface. The earphone 3 can also be connected to this wired interface while the otoacoustic screening device 2 is charging to continue hearing screening.
