A high pitch enhanced passive radiator is adapted to be utilized in a passive radiator speaker. The high pitch enhanced passive radiator includes a shell, a woofer, and the passive radiator speaker. The shell has a first slot and a second slot. The woofer is connected to the first slot. The passive radiator speaker is connected to the second slot and includes a flange, a piezoelectric speaker, and a counterweight plate. The piezoelectric speaker is connected to the flange. The projected area of the counterweight plate and the projected area of the piezoelectric speaker at least partially overlap with each other.

The present disclosure discloses a MEMS speaker including a substrate with a cavity and a sounding assembly connected with the substrate, the substrate comprising an outer surface away from the cavity and connected with the sounding assembly, a top surface opposite to the outer surface and a side surface respectively connected with the outer surface and the top surface; a printed circuit board with a through hole and connected with the outer surface of the substrate; a first shell connected with the top surface of the substrate; and a damping mesh covering the through hole and connected with the printed circuit board; wherein sounds emitted by the sounding assembly transmit outward through the through hole and the damping mesh. Compared with the related art, MEMS speaker disclosed by the present disclosure has a better reliability.

A venturi expander is mounted on a speaker enclosure to receive the rearward-propagated sound waves and to extend the propagation path. The venturi expander's reflective sides direct the rearward sound to the sides or top or bottom of the speaker enclosure to produce a reflected sound surrounding the speaker enclosure and producing sound to the sides of the speaker substantially as projected from the front of the speaker.

In at least one embodiment, an audio amplifier system is provided. The system includes a loudspeaker and an audio amplifier. The loudspeaker transmits an audio output into a listening environment. The audio amplifier is programmed to receive an audio input signal and to generate an excursion signal corresponding to a first excursion level of the voice coil based on the audio input signal. The audio amplifier is further programmed to limit the excursion signal to reach a maximum excursion level and to determine a target pressure for an enclosure of the loudspeaker based on the maximum excursion level. The audio amplifier is further programmed to generate a target current signal based at least on the target pressure and to convert the target current signal into a target voltage signal to a target driving signal to drive the voice coil to reach the maximum excursion level.

A sound box assembly for a display apparatus, includes: a housing defining a chamber therein, and a connecting part connected to the housing, and being configured to be connected with the display apparatus; and a loudspeaker arranged in the chamber of the housing, a sound-image center being disposed at a center position of the display apparatus when the loudspeaker playing sound. The loudspeaker includes a squawker arranged at a middle portion of the housing, a woofer and a tweeter. One of the woofer and the tweeter is arranged above the squawker and the other one of the woofer and the tweeter is arranged below the squawker.

A loudspeaker comprises an enclosure, at least one dynamic driver mounted in the enclosure, and at least one porous monolithic block. The at least one porous monolithic block comprises a plurality of pores and is mounted within the enclosure.

Systems of the present disclosure include an electronic device with a chassis and a speaker assembly. The speaker assembly can include a speaker support surrounding a speaker and coupled to the chassis via a spring element. The spring element can be monolithically formed with a main body of the speaker support and be configured to reduce transmission of vibrations from the speaker to the chassis. For example, the spring element can include an arm that extends within an opening of the main body to connect the main body to a fastener secured to the chassis. The spring element can be provided with features that facilitate wide distribution of loads and relative movement between the speaker assembly and the chassis.
