Abstract: An electronic apparatus and a method for activating a specified function are provided. The electronic apparatus includes a speaker, an audio signal processor and an application processor. The audio signal processor senses a variation of an acoustic condition of the speaker. The application processor is used for: generating a logic high or low signal in response to the sensed variation of the acoustic condition; interpreting the logic high or low signal as a control signal; and performing an instruction corresponding to the control signal.

Abstract: A portable electronic device having a speaker module is provided. The speaker module includes: a speaker unit; a back chamber; an acoustic region coupled between the speaker unit and the back chamber; and a porous material at least partially filling a portion of the front chamber, the back chamber, or the channel, for improving and extending bass performance and relieving a acoustic effect caused by the acoustic region coupling the speaker unit and back chamber. Moreover, the portable electronic device is advantageously able to compensate a resonance degradation caused by the porous material.

Abstract: A micro-speaker includes a speaker monomer, a housing and a waterproof membrane. The housing accommodates the speaker monomer and has an opening to output a sound generated by the speaker monomer. The waterproof membrane seals the opening and transmits the sound generated by the speaker monomer. The waterproof membrane has a center area and a peripheral area surrounding the center area, and a stiffness of the center area is greater than a stiffness of the peripheral area.

Abstract: An electronic apparatus and a method for providing a sound system of the electronic apparatus are provided herein. The electronic apparatus has a housing, a speaker and a bracket. The housing has a space and a channel, which is coupled to the space. The speaker is placed in the space. The bracket has a first end coupled to the channel and is movable relative to the housing. A sound mode of the electronic apparatus may be switched from a first mode to a second mode by positioning a second end of the bracket from a first position in the channel to a second position away from the channel.

Abstract: A speaker module includes a speaker unit, a main body and a speaker carrier. The main body includes a sound outlet opening and an air pressure regulating structure. The sound outlet opening is configured to expose the speaker unit. The speaker carrier is configured to carry the speaker unit. The speaker carrier is disposed in the main body together with the speaker unit, and forms a resonance space with the main body. The air pressure regulating structure is configured to regulate the air pressure of the resonance space.

Abstract: An audio signal measurement method for a speaker and an electronic apparatus having the speaker are provided. The electronic apparatus further has a processing circuit and a power amplifier. The processing circuit is coupled to the speaker and configured to execute a time domain to frequency domain transform according to a voltage value of an audio signal and a current value of current feedback from the speaker so as to obtain a frequency response curve. The power amplifier is coupled to the speaker and configured to drive the speaker according the voltage value of the audio signal. The processing circuit is capable of determining whether the frequency response curve is located within a predetermined area such that the processing circuit generates a signal when the frequency response curve is located out of the predetermined area. Thereby, the electronic apparatus may measure its transducer distortion and acoustic box leakage.

Abstract: A robot arm for delivering a wafer is disclosed which comprises a carrier plate, an inner ring, a driving device and at least a contact pad. The inner ring is disposed on the carrier plate and defines at least a through-hole. The driving device is connected to the carrier plate to move the carrier plate. The contact pad is disposed at the through-hole of the inner ring and comprises a first protrusion portion and a second protrusion portion. The first protrusion portion protrudes from a first surface of the inner ring and is used for being in contact with the wafer to prevent it from being in contact with the first surface. The second protrusion portion is lodged in the through-hole to fix the contact pad at the inner ring.
