This invention discloses a sound field adjustment method and a computer-readable storage medium. The sound field adjustment method is applied to a multi-functional cockpit and includes: acquiring the user's position and spatial structure information of the sound field space; for any target speaker among the various speakers installed in the sound field space, calculating the sound field space parameters corresponding to the user's position based on the user's position and spatial structure information; determining the target processing parameters of the target speaker based on the sound field space parameters; processing the input audio signal of the target speaker according to the target processing parameters to obtain an output audio signal, and outputting the output audio signal using the target speaker. This invention improves the user experience in a multi-functional cockpit.

An in-ear audio glasses temple and smart glasses are disclosed. The in-ear audio glasses temple includes a temple body and an audio component. The temple body includes a temple arm, an ear hook, and an in-ear portion. The ear hook is mounted on the temple arm, and the in-ear portion is slidably mounted on the end of the temple arm and has a sound hole. The audio component is installed in the in-ear portion and corresponds to the sound hole. The first end of the temple arm is used to connect to the frame, and the ear hook can be suspended on the ear so that the in-ear portion installed on the end of the temple arm is aligned with the external auditory canal. Sliding the in-ear portion can drive the audio component in and out of the external auditory canal. The smart glasses include a frame with lenses and two sets of in-ear audio glasses temples. The two sets of in-ear audio glasses temples are symmetrically arranged on the left and right ends of the frame and are hinged to the frame by the temple arm. The two ear hooks are suspended on the ears to wear the smart glasses, and the two in-ear portions are slid into the external auditory canal so that the audio component plays sound in the external auditory canal, thereby improving the listening effect and ensuring privacy.

The invention discloses a digital multimedia exhibition hall control method, a terminal, equipment and a storage medium, and the method comprises the steps: periodically obtaining a current monitoring video through people stream portrait recognition equipment according to a preset collection period in a projection process; face recognition processing is carried out on each video frame in the current monitoring video in sequence, a crowd trend recognition result is obtained, and a block group number of a target block group where the current crowd is located is recorded in the crowd trend recognition result; based on the crowd trend identification result, generating a control instruction for the driving device; and sending a control instruction to the driving device, so that the driving device drives the mobile projector and the audio playing device to move to a position corresponding to the target block group. According to the scheme, the problem of poor experience of exhibition viewers in related technologies can be solved.

This invention discloses a foldable adjustable mid-high frequency speaker unit, relating to the field of speaker technology. It includes a speaker body with storage slots on both sides. A soundbar is housed within each storage slot, and one end of the soundbar is fixed within the storage slot via a folding mechanism. The folding mechanism extends the soundbar to both sides of the speaker body and is equipped with hinges that allow for flexible adjustment of the soundbar's horizontal and vertical placement. This invention extends the soundbar to both sides of the speaker body via the folding mechanism, and, in conjunction with the hinges, allows for flexible adjustment of the soundbar's horizontal and vertical placement. This actively increases the horizontal and vertical spacing between the mid-high frequency drivers, improving the separation of the left and right channels from a sound source layout perspective, widening the horizontal sound diffusion angle, and enhancing the vertical projection density, achieving a wide-range, distortion-free listening effect across the entire area.

Provided are an auscultation auxiliary device and a stethoscope capable of improving the listening performance of auscultation sounds. The auscultation auxiliary device (6) has a hollow sheet (7), and the hollow sheet (7) is mounted on a diaphragm (30) provided on a chest listening device (3) in a manner that allows loading and unloading. The hollow sheet (7) has: a first membrane portion (7a), which is mounted on the diaphragm (30) provided on the chest listening device (3) in a manner that allows loading and unloading, a second membrane portion (7b), which abuts against a part of the examination object (2) and can deform along the concave and convex deformation of the part of the examination object (2), and a hollow portion (7c), which is formed into a sealed state between the first membrane portion (7a) and the second membrane portion (7b); a transmission medium for transmitting sound is sealed in the hollow portion (7c).

The application provides a nerve stimulation regulation system and an artificial hearing device, the regulation system comprising: a signal source configured to acquire an external signal; a signal processing module configured to determine whether a current acoustic environment is a quiet environment based on the external signal, and if so, output a closed-loop debugging command to a control module; the control module is configured to output a special test signal to a stimulation module and an acquisition command to a signal acquisition module based on the closed-loop debugging command; the stimulation module is configured to output a test special electric pulse based on the special test signal; the signal acquisition module is configured to acquire a target auditory electric signal based on the acquisition command; the signal processing module is further configured to automatically update stimulation strategy coding parameters according to the target auditory electric signal. The application can automatically induce and acquire a target auditory electric signal for closed-loop parameter adjustment without affecting the normal listening experience of a user.

The utility model discloses a six-sound-channel three-frequency-division automobile sound box, which adopts the design of two power amplifier modules, one power amplifier module is four-sound-channel output, the other power amplifier module is two groups of CENTER middle outputs which are matched left and right, a six-sound-channel power amplifier output function is realized, and the two groups of CENTER middle outputs which are matched left and right physically compensate the tone quality of intermediate frequency and high frequency. Meanwhile, the output function of the subwoofer is added, so that the bass is thicker and firmer, the layering sense of the high pitch, the alto pitch and the bass is clearer, the beauty of music is better reflected, and the experience feeling is stronger; in addition, the volume and amplitude of the FL signal source and the FR signal source can be respectively adjusted through the arrangement of the middle volume control module, and the proportions of high and low frequency components in the FL signal source and the FR signal source can be respectively adjusted through the arrangement of the treble and bass attenuation circuit control module, so that the alto is fully played, and an ideal alto state is achieved.
