The application discloses an eartip, an earphone device, an earphone housing and a hearbud housing device. The eartip can include an outer portion, an inner portion, and an encapsulated volume formed by the inner and outer portion, wherein the outer portion is designed to contact the ear canal, and wherein the inner portion is designed to fit upon a stent. In an alternative embodiment, the airtip can include an inverted body, wherein when the inverted body is at least partially folded on itself the inverted body is arranged to include a bulbous region sized for insertion in an ear canal, a cavity internal to the bulbous region that holds a gas, where increasing pressure on the bulbous region releases a portion of the gas.

The application is directed to an eartip. The eartip can include an outer portion, an inner portion, and an encapsulated volume formed by the inner and outer portion, wherein the outer portion is designed to contact the ear canal, and wherein the inner portion is designed to fit upon a stent.

The present disclosure discloses a speaker including a frame with two open ends, a vibration system sealing one open end of the frame, a magnetic circuit system, and an air-permeable mesh. The magnetic circuit system includes a yoke sealing another open end of the frame, a first magnet, a second magnet arranged at two opposite sides of the first magnet, a through hole penetrating the yoke and arranged at another two opposite sides of the first magnet, and an extension wall bending and extending from a side of the through hole close to the first magnet in a direction close to the vibration system. The air-permeable mesh is attached to the yoke and covers the through hole. Compared with the related art, the speaker disclosed by the present disclosure has a better acoustic performance.

The present disclosure relates to a pair of glasses. The pair of glasses may include a frame, one or more lenses, and one or more temples. The pair of glasses may further include at least one low-frequency acoustic driver, at least one high-frequency acoustic driver, and a controller. The at least one low-frequency acoustic driver may be configured to output sounds from at least two first guiding holes. The at least one high-frequency acoustic driver may be configured to output sounds from at least two second guiding holes. The controller may be configured to direct the low-frequency acoustic driver to output the sounds in a first frequency range and direct the high-frequency acoustic driver to output the sounds in a second frequency range. The second frequency range may include one or more frequencies higher than one or more frequencies in the first frequency range.

A tactile audio system and associated methods are disclosed. In one example, the tactile audio system includes a signal processor configured to separate an input signal into a transient group and a sustained group. In one example, the tactile audio system includes a signal processor configured to separate an input signal into a plurality of frequency bands for each of the transient group and the sustained group. A number of transducers are provided to generate a tactile response corresponding to portions of the separated audio signal.

This application provides a speaker and a mobile terminal. The speaker includes a housing and a kernel located in the housing, where there is a front cavity and a rear cavity in the housing, the front cavity is in communication with the outside, and the rear cavity is an isolated cavity. In addition, to reduce a space area occupied by the entire speaker, the front cavity and the rear cavity are disposed in a stacked manner when being disposed. Specifically, the front cavity and the rear cavity are at least partially stacked along a thickness direction of the kernel. Therefore, the rear cavity is disposed in space of the entire speaker in the thickness direction of the kernel, to reduce an area occupied by the entire speaker in the mobile terminal on the premise that a size of the rear cavity meets a requirement.

The present disclosure relates to a pair of glasses. The pair of glasses may include a frame, one or more lenses, and one or more temples. The pair of glasses may further include at least one low-frequency acoustic driver, at least one high-frequency acoustic driver, and a controller. The at least one low-frequency acoustic driver may be configured to output sounds from at least two first guiding holes. The at least one high-frequency acoustic driver may be configured to output sounds from at least two second guiding holes. The controller may be configured to direct the low-frequency acoustic driver to output the sounds in a first frequency range and direct the high-frequency acoustic driver to output the sounds in a second frequency range. The second frequency range may include one or more frequencies higher than one or more frequencies in the first frequency range.
