Abstract

An external sound amplifying device for a telephone, comprising: a housing removably mounted to a telephone handset; a microphone adjacent to an earpiece of the handset to collect telephone sounds emitted by the earpiece when the housing is mounted to the handset; a loudspeaker; a vibration sensor for sensing vibration generated when the housing moves; a sound sensor; a battery cell; and a processing unit. When the vibration sensor senses vibration, the processing unit enables the battery unit to supply power to the loudspeaker, so that the loudspeaker can amplify telephone sound transmitted by the microphone. When the processing unit judges that the vibration sensor does not sense vibration for a preset time interval and the sound sensor does not sense sound for the preset time interval, the processing unit enables the battery unit to stop supplying power to the loudspeaker.

Description

External loud-speaker for telephone

Technical Field

The present invention relates to a sound amplifying device, and more particularly to an external sound amplifying device for a telephone.

Background

The indoor wireless telephone set comprises a slave set and a master set. The master machine is fixedly arranged at a certain indoor position and is connected with a local line of a telecommunication office through a telephone line, and the sub machine is in wireless communication with the master machine, so that a user can hold the sub machine by hand and walk around to make a call indoors.

Currently, some wireless telephone handsets have a sound amplification function. However, there are still some cordless telephone handset types that do not have a sound amplifying function, and there are also external speakers sold in the market that can be removably mounted on the cordless telephone handset to amplify the telephone sound in the headset of the handset. The conventional external speaker is generally powered by a dry battery and provides a volume button for operation by a user. When the user uses the sub-machine with the external loudspeaker, the user must operate the volume button to start the loudspeaker function of the external loudspeaker, and the battery indicator lamp is lighted at the moment. However, after the user finishes the call, if the user forgets to operate the volume button again to turn off the sound amplifying function of the external microphone, the battery is always in a power consumption state, and thus the battery is quickly discharged, which results in frequent battery replacement. Therefore, a solution is necessary.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

Referring to fig. 1 to 4, the external sound amplifying device 2 of the present invention is adapted to be removably mounted on a handset 1, wherein the handset 1 includes a barrel 10 and an earphone 11.

In the present embodiment, the external microphone 2 for a telephone comprises a housing 20, a mounting band 28, a sound collector 29, a microphone 21, a microphone 22, a volume adjustment knob 220, a vibration sensor 23, a sound sensor 24, a light emitting unit 27 (such as an LED, etc.), a battery unit 25, and a processing unit 26.

The housing 20 is removably mounted to the body 10 of the handset 1. In this embodiment, the housing 20 is removably mounted to the barrel 10 of the handset 1 by the mounting strap 28. In this embodiment, the two ends of the mounting band 28 are fixed on the housing 20, and may be, for example, elastic bands. In addition, since the external sound amplifying device 2 for a telephone of the present invention receives sound through the microphone 21 disposed inside the casing 20, the sound receiving hole 201 is required to be disposed on the back surface of the casing 20.

In the present embodiment, the sound collector 29 is shaped like a trumpet, and has a large diameter opening 291 and a small diameter opening 292, the small diameter opening 292 is fixedly installed on the back surface of the housing 20, the large diameter opening 291 is spaced apart from the back surface of the housing 20, and the diameter of the opening of the small diameter opening 292 is larger than the diameter of the sound collecting hole 201 of the housing 20, so that the microphone 21 installed inside the housing 20 can collect sound through the sound collecting hole 201 and the sound collector 29. In the present embodiment, the opening of the small-diameter opening 292 of the sound collector 29 is provided concentrically with the sound receiving hole 201 of the housing 20.

In the present embodiment, the microphone 21 is disposed in the housing 20 adjacent to the acoustic hole 201. When the casing 20 is mounted on the barrel 10 of the handset 1, the sound collector 29 is disposed between the casing 20 and the barrel 10 of the handset 1, and the large-diameter opening 291 of the sound collector 29 covers the earphone 11 of the handset 1, so that the microphone 21 can collect the telephone sound emitted from the earphone 11 of the handset 1 through the sound receiving hole 201 and the sound collector 29.

The microphone 22 is disposed inside the casing 20 and can amplify sound through a plurality of sound amplifying holes disposed on the front surface of the casing 20.

The volume adjustment knob 220 extends through the housing 20 and is operable by a user to adjust the amplification volume of the microphone 22.

The vibration sensor 23 is disposed in the housing 20 and is used for sensing vibration generated when the housing 20 moves. In the present embodiment, the vibration sensor 23 may be, for example, a ball sensor or a spring sensor.

The sound sensor 24 is disposed in the housing 20 and is used for sensing a telephone sound emitted from the microphone 22, or a user speaking sound, etc.
