Systems, apparatuses, and methods are described for a privacy blocking device configured to prevent receipt, by a listening device, of video and/or audio data until a trigger occurs. A blocker may be configured to prevent receipt of video and/or audio data by one or more microphones and/or one or more cameras of a listening device. The blocker may use the one or more microphones, the one or more cameras, and/or one or more second microphones and/or one or more second cameras to monitor for a trigger. The blocker may process the data. Upon detecting the trigger, the blocker may transmit data to the listening device. For example, the blocker may transmit all or a part of a spoken phrase to the listening device.

An object information acquiring apparatus includes a detector including m-number of probes to which a voltage is supplied and a current/voltage conversion circuit which converts a current into a voltage, a receiver processing electric signals from the probes, and a relay board respectively relaying power distribution lines between the electrical power source and the probes and signal wirings between the receiver and the probe, wherein the relay board receives input of signal wirings and power distribution lines from n-number (mn) of probes among the m-number of probes, connects the signal wirings from the n-number of probes to the receiver, and connects, to the electrical power source side, the power distribution lines of a number that is fewer than the power distribution lines from the n-number of probes.

According to an aspect, an apparatus may include a media streaming device including electronic circuitry configured to receive media content wirelessly from a media content source, and an audio output cord segment having a first end portion configured to be coupled to an audio input port of the media streaming device, and a second end portion configured to be coupled to an audio rendering device, where the electronic circuitry is further configured to transmit audio content through the audio output cord segment to the audio rendering device.

A Bluetooth (BT) device includes a host processor and a BT controller coupled by a Host Controller Interface (HCI) including a Host Controller Transport Layer and a HCI Driver. The host processor implements an applications layer and includes HCI firmware for communicating via the Host Controller Transport Layer with the BT controller. The BT controller includes a processor coupled to a memory and to a transceiver, and a RF driver. The HCI firmware also includes HCI command code for a user to define a topology of the BT network including configuring the BT device in a current chain including a plurality of BT devices including configuring from which BT device it receives data from and which BT device it forwards data to. For communicating data across the BT network the BT device forwards the data without host processor involvement in at least resending the data back to its BT controller.

An acoustic playback system including a digital filter; and a plurality of digital modulators each of which output a digital signal to one of a plurality of speakers driven by digital signals having different play back bandwidths; wherein the digital filter converts a digital audio signal which is input into a plurality of digital audio signals of a plurality of frequency bandwidths corresponding to play back bandwidths of the speakers, and outputs each of the digital audio signals of the plurality of frequency bandwidths to one of the plurality of digital modulators; each of the digital modulators outputs the modulated digital signal to the speaker of a play back bandwidth corresponding to a frequency bandwidth of the digital audio signal which is input by performing miss-match shaping after noise shaping to a digital audio signal; and each number of bits of a digital signal of the digital modulators is different.

The present disclosure relates to an earphone socket, an earphone plug, an earphone and an electronic device. For example, the earphone socket may include a socket body in which an earphone jack is formed. The earphone socket may include multiple ground terminals, which may be arranged in the earphone jack. The ground terminals may contact a ground section disposed on an earphone plug when the earphone plug is inserted into the earphone jack. The technical solutions of the present disclosure reduce earphone crosstalk and improve tone quality.
