Embodiments are directed to a sealed pipe-loaded loudspeaker for augmenting low frequency response in a portable electronic device. A loudspeaker transducer is configured to radiate sound directly out of a forward radiation area and incidentally out of a rearward radiation area, and a sealed transmission line forming a closed pipe acoustically coupled to the transducer through which the rearward radiation propagates to produce standing waves corresponding to the dimensions of the closed pipe, wherein resonances apply a loading to a diaphragm element of the transducer to lower its resonance frequency. An acoustical wave front radiates away from the diaphragm element for the direct sound and is emitted outside of the device, and the rearward radiation is not emitted from the device.

The present disclosure relates to an acoustic output device. The acoustic output device may include an earphone core, a controller, a power source, and a flexible circuit board. The earphone core may include at least one low-frequency acoustic driver configured to output sounds from at least two first guiding holes and the at least one high-frequency acoustic driver configured to output sounds from at least two second guiding holes. The controller may be configured to direct the at least one low-frequency acoustic driver to output the sounds in a first frequency range and direct the at least one high-frequency acoustic driver to output the sounds in a second frequency range. The power source may be configured to provide power supply for the earphone core. The flexible circuit board may be configured to connect the earphone core with the power source.

In an embodiment, an electronic device 1 has a panel 20, a housing 10 that holds the panel 20, and a piezoelectric element 30 installed on the rear side of the panel 20, wherein the piezoelectric element 30 is installed at a position that allows for the vibration amplitude of the panel 20 to become the highest on the side closer to the center of the panel 20 in the longitudinal direction from the installed position of the piezoelectric element 30. The electronic device is capable of causing an entire panel to vibrate in a stable manner.

An electronic device includes a casing, a speaker enclosure and an actuating and sensing module. The casing has an opening. The speaker enclosure is disposed within the casing to enclose a speaker, in communication with the opening of the casing and divided into a first speaker compartment and a second speaker compartment by a partition plate disposed corresponding to the opening, so that the opening of the casing is in communication with the first speaker compartment and the second speaker compartment. The actuating and sensing module is disposed within the first speaker compartment. The speaker is disposed within the second speaker compartment. The actuating and sensing module comprises a fluid transportation device and a sensor. The fluid transportation device is driven to transport a fluid from outside the casing into the first speaker compartment through the opening of the casing to make the fluid sensed by the sensor.

A sound enhancing device for improving voice reception of a smartphone microphone is attachable to the rear surface of a smartphone opposite the surface of the smartphone having a display. The device has a deflector in a sliding engagement within a cavity of a housing moveable between a stowed position and a deployed position. A reflective curved area positioned on a first surface of the deflector captures and reflects sound waves from the voice of a user toward a microphone of the smartphone.

The loudspeaker module is installed in an interior of an electronic terminal and comprises an outer casing in which a vibration system and a magnetic circuit system are received, the magnetic circuit system comprises a basin-like stand fixed on the outer casing, a position of the outer casing corresponding to a sidewall of the basin-like stand is provided with a rear sound exit hole, the rear sound exit hole is communicated with an inner cavity of the module and an inner cavity of the electronic terminal; a chamfered plane is disposed at an upper end of a sidewall of the basin-like stand corresponding to the rear sound exit hole, and the chamfered plane is disposed on a side of the sidewall of the basin-like stand adjacent to the rear sound exit hole.
