Abstract: In a display assistant device, a speaker is mounted in a waveguide structure which is at least partially disposed beneath a display screen. The waveguide structure is mounted in an exterior housing which includes speaker grills distributed on a plurality of surfaces of the exterior housing, permitting sound waves from the speaker to be projected outside the exterior housing. A cover structure is disposed on top of the waveguide structure to conceal the waveguide structure and speaker within the exterior housing. The cover structure has a tilted bottom surface configured to be suspended above the waveguide structure and to be separated by a first space. Sound waves projected from an upper portion of the speaker are reflected by the tilted bottom surface and are guided through the first space to exit the device from a speaker grill portion located on a rear side of the exterior housing.

Abstract: An elliptically shaped speaker has a driver assembly which may include a woofer driver and a tweeter driver. The speaker has a uniquely designed bridge member. The bridge member acts both as a structural element and waveguide for the tweeter. It has a specific elongated, elliptical shape that allows the speaker to be inserted into a corresponding cut-out opening in a wall, ceiling or any other structural panel, then rotated behind the panel and re-inserted from behind into the opening, thereby providing a secure seal and exact positioning within the panel. The resulting system allows for a low frequency speaker to be installed behind the panel with a noticeably smaller opening than the total size of the speaker.

Abstract: A hybrid actuator includes a housing for defining an external appearance, a stator having a coil, a vibrator having a permanent magnet which vibrates due to a mutual electromagnetic force with the stator, an elastic member for elastically supporting the vibrator relative to the housing, and a piezoelectric element attached to one surface of the housing.

A virtual image generation system comprises memory storing a three-dimensional scene, a sensor configured for detecting a focus of the end user on a sound source, a speaker configured for conveying sounds to the end user, and a control subsystem configured for causing the speaker to preferentially convey a sound originating from the sound source in response to detection of the focus, and for rendering image frames of the scene, and a display subsystem configured for sequentially displaying the image frames to the end user.

Abstract: An accessory for eyeglasses that functions as a combined hearing aid and/or eyeglasses retention device which can maintain housings of behind the ear (BTE) hearing aids in place on a user's ears. The combined hearing aid and/or eyeglasses retention device can also maintain eyeglasses from slipping down the nose of a user which also maintains the device at its optimal position to retain housings of BTE hearing aids in place. The combined hearing aid and/or eyeglasses retention device also prevents displacement of BTE housing(s) off a user's ears when a user removes a mask. The combined hearing aid and/or eyeglasses retention device can also be a ‘standalone’ eyeglasses retention device when a user does not wear BTE hearing aids.

Abstract: A housing assembly and an electronic device are provided. The housing assembly comprises a middle frame. The middle frame comprises a side surface. A first sound cavity, a second sound cavity and a sound output hole are arranged at the middle frame. One end of the first sound cavity corresponds to a receiver. The other end of the first sound cavity extends toward the side surface and communicates with the second sound cavity. The second sound cavity extends in a lengthwise direction of the side surface and is in communication with the sound output hole. The invention employs a sound guiding channel having an offset configuration to communicate a receiver with an external environment, thereby ensuring quality of an audio output while reducing an occupied region near the sound output hole and improving the appearance of a product to meet the appearance requirement.
