A display device including a display panel configured to display an image; a touch sensing device configured to sense a touch of an object; a sound driver configured to generate and transmit a first sound driving signal and a second sound driving signal according to first sound data and second sound data; and a sound generator configured to generate a sound according to the first and second sound driving signals, such that a sound pressure level in a first frequency range is between first and second sound pressure levels in a first operating mode and a second operating mode, wherein the display device is in the first operating mode in response to the touch sensing device not sensing the touch of the object, and the display device is in the second operating mode in response to the touch sensing device sensing the touch of the object.

The present disclosure provides example electronic devices, auxiliary materials, and rear housing assemblies of an electronic device. One example electronic device includes a rear housing, a middle frame, a functional component, a speaker box, and an auxiliary material, where the rear housing covers the middle frame and forms a mounting cavity together with the middle frame. The functional component, the speaker box, and the auxiliary material are disposed in the mounting cavity. The functional component is adjacent to the speaker box. A rear acoustic cavity of the speaker box is connected to the mounting cavity. The auxiliary material is bonded between the rear housing and the functional component. The auxiliary material has a weak-adhesion surface and a strong-adhesion surface that are opposite to each other. The weak-adhesion surface is bonded to the functional component, and the strong-adhesion surface is bonded to the rear housing.

The present invention discloses a speaker device. The speaker device comprises a speaker box, a heat source, and a heat conducting member; the speaker box comprises a housing, a speaker, a sound-guiding channel, and a heat conducting plate; the speaker includes a diaphragm, the first receiving space is divided into a front sounding chamber and a back chamber, and the sound-guiding channel communicates the front sounding chamber with the outside and forms a front chamber together with the front sounding chamber; the housing having an opening penetrating therethrough, the opening communicates with the front chamber, and the heat conducting plate covers on the opening, an adjusting hole penetrates through the housing and communicates with the back chamber; an valve covers on the adjusting hole and a controller for outputting a control signal to control the valve to open or to close.

An electronic device is provided. The electronic device may include: a housing including a cover and at least one first opening; a first acoustic module comprising a speaker disposed in an internal space of the housing; and at least one path configured to guide sound signals generated by the first acoustic module to an outside, the at least one path including: a first space defined by the first acoustic module and at least a portion of the housing; a second space connecting the first space to the first opening and configured to guide a sound signal having a first frequency band toward the first opening; and a third space connecting the first space to a second opening at least partially provided between the housing and the cover and configured to guide a sound signal having a second frequency band lower than the first frequency band toward the second opening.

A mobile terminal includes a housing and a speaker component including a speaker unit that divides a cavity of the speaker component into a front speaker box and a rear speaker box, an air vent coupled to an inner cavity of the housing is disposed on a wall of the rear speaker box, and a flexible sound absorbing member that can absorb a sound and damp vibration is disposed on a wall of the inner cavity of the housing.

The present disclosure is related to a mobile phone cover providing passive noise reduction of at least one microphone audio input signal, comprising a supporting frame (13). The supporting frame (13) is arranged with an extension element with a compartment (15) facing upwards with a partly open surface on a same side as a display surface of the mobile phone, the compartment (15) is adapted to support a porous body (17) providing the passive noise reduction.

An electronic device housing may include a display cover layer that overlaps an array of pixels. The cover layer or other portion of the housing may have an opening that forms an optical and audio port. Optical and audio components may be coupled to the port. A port cover may cover some or all of the port. The port cover may include one or more layers of mesh or other materials that allow light and sound to pass while blocking environmental contaminants. The optical components may include an ambient light sensor or other devices that receive light and/or may include devices that emit light. The audio components may include a microphone and/or a speaker. The optical component may emit or receive light that passes through the audio component. A structure in the interior of the housing may form a passageway coupled to the port through which sound and light passes.

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.
