TL;DR: In this paper, an audio self-test method of communication terminals is described, which includes the steps: 1, a to-be-tested terminal is manually or automatically placed in a test box; 2, a test signal and a test result are stored in the to be tested terminal; 3, the test signal is sent out the internally stored test signal through a speaker, a receiver or a vibrator.
Abstract: The invention discloses an audio self-test method of communication terminals. The method includes the steps: 1, a to-be-tested terminal is manually or automatically placed in a test box; 2, a test signal and a test result are stored in the to-be-tested terminal; 3, the to-be-tested terminal sends out the internally stored test signal through a speaker, a receiver or a vibrator of the to-be-tested terminal and receives the test signal through the microphone of the to-be-tested terminal; computing parts, such as a processor, of the to-be-tested terminal analytically processes the test signal received, thus obtaining the test result; 4, after testing or after the test signal is received, the to-be-tested terminal is taken out manually or automatically.

TL;DR: In this paper, a miniature portable telephone set was used with a wristwatch by using a speaker and a microphone simultaneously when a couple of ends of a band fitted to a wrist of the user is not connected together.
Abstract: PURPOSE: To obtain the miniature portable telephone set in common use with a wrist watch by using a speaker and a microphone simultaneously when a couple of ends of a band fitted to a wrist of the user is not connected together. CONSTITUTION: The stiffness of a band 3 allows two microphone container 6 and speaker container 8 to be separated at a proper distance. When ends of the band are not connected to each other, a microphone and a speaker are used at the same time. A case 2 acts like a grip to grip the main body to operate an acting part of a pushbutton. Thus, the compact portable telephone set is easily hold and when the telephone set is not in use, the main body is used for a wrist watch.

TL;DR: In this article, a test signal generating means is used to generate test signals from the speakers 1-3 and a signal processing means 18 using the other speakers 4, 5 to collect the sound of the test signal, analyzing the sound collection signal to output a control signal S, and the amplifier means is controlled by the control signal.
Abstract: PURPOSE:To keep the sound field of a listener in the best state at all times by using one speaker for an input (microphone) device in common in the acoustic reproduction device provided with plural speaker systems so as to automatically set a level or the like of an output device. CONSTITUTION:Amplifier means 6-10 amplifying a sound source 16 of plural channels and plural speaker systems 1-5 to reproduce the amplified signal are provided to the equipment. Moreover, the equipment is provided with a test signal generating means 17 outputting a test signal from the speakers 1-3 and a signal processing means 18 using the other speakers 4, 5 to collect the sound of the test signal, analyzing the sound collection signal to output a control signal S, and the amplifier means is controlled by the control signal. Furthermore, the sound sources of plural channels are used for the test signals.

TL;DR: In this article, a microphone is arranged inside a resonator, which is tuned to a certain resonance frequency, and the impedance break at the resonance frequency allows alignment to the impedance of the surrounding medium so that optimal antenna cross-sections can be used.
Abstract: In order to increase the noise gap between incident- and interference signals, in particular wind noise, microphone (5) is arranged inside a resonator (2) which is tuned to a certain resonance frequency. The resonator can also be a silator (2a). The impedance break at the resonance frequency allows alignment to the impedance of the surrounding medium so that optimal large antenna cross-sections can be used. The sensitivity of the microphone is also increased by the sound- pressure increase at resonance. Since the shape of the resonators can be freely chosen, they can be integrated into existing vacant spaces, for example wings of search drones.
