Abstract: Embodiments of this application provide a sound image calibration method and apparatus. The method includes: A terminal device outputs a first target audio signal using a first play component, and a second target audio signal using a second play component, where a sound image is located at a first location. The terminal device receives a second operation on a second control; in response, it outputs a third target audio signal using the first play component, and a fourth target audio signal using the second play component, where the sound image is located at a second location. The distance between the second location and the central location of the terminal device is less than the distance between the first location and the central location. This allows the terminal device to turn on the control for sound image calibration, adjust the sound image closer to the central location, improve audio replay effect.

Abstract: This application provides a sound processing method and apparatus thereof. When the method is implemented, an electronic device such as a mobile phone may learn a device action and a music material matching the action. In this way, a user may drive the electronic device to perform an action through his own action (such as shaking his head, shaking his hands, or the like) when playing audio. The electronic device may recognize the actions through movement detection, and determine a music material matching the action according to a preset association relationship, so as to add an entertaining interactive effect to the audio being played, increase fun of an audio playing process, and meet a requirement of the user interacting with the audio being played.

Abstract: The present disclosure belongs to technical field of thermoelectricity, particularly relates to a cogeneration apparatus, including a thermal collector and a thermoelectric power generation component, the thermoelectric power generation component is disposed on the thermal collector and an end face at one side contacts with the thermal collector, the cogeneration apparatus can collect the heat generated after gas combustion through the thermal collector, the heat is used for heating one end of the thermoelectric power generation component, so that two ends of the thermoelectric power generation component form a temperature difference, thereby realizing power generation. In this solution, a compensating distance is disposed between an upper end of the thermoelectric power generation component and an upper end of the thermal collector.

Abstract: An optical module and an optical system thereof for head-up display, and a vehicle, relating to the technical field of head-up display. The optical module includes an image generation element and a light blocking assembly which are provided in sequence; the image generation element is used for forming an image signal, the image signal being incident on a receiving end through the light blocking assembly; and the light blocking assembly is further used for transmitting part of light in external light according to a polarization direction and/or wavelength. The image signal is not affected by the light blocking assembly when passing through the light blocking assembly; the external light passes through the light blocking assembly and the image generation element in sequence, and does not generate an image after passing through the image generation element; light heat of the external light would be gathered on the image generation element.
