Unless otherwise apparent from the context, or otherwise indicated, like reference numbers in the figures refer to the same structure or operation.

As used in this application and the appended claims, the terms "a," "an," "the," and/or "the" are not intended to be inclusive in the singular, but rather are intended to be inclusive in the plural unless the context clearly dictates otherwise. In general, the terms "comprises" and "comprising" merely indicate that steps and elements are included which are explicitly identified, that the steps and elements do not form an exclusive list, and that a method or apparatus may include other steps or elements.

The relative arrangement of the components and steps, the numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the present application unless specifically stated otherwise. Meanwhile, it should be understood that the sizes of the respective portions shown in the drawings are not drawn in an actual proportional relationship for the convenience of description. Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail but are intended to be part of the specification where appropriate. In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.

In the description of the present application, it is to be understood that the orientation or positional relationship indicated by the directional terms such as "front, rear, upper, lower, left, right", "lateral, vertical, horizontal" and "top, bottom", etc., are generally based on the orientation or positional relationship shown in the drawings, and are used for convenience of description and simplicity of description only, and in the case of not making a reverse description, these directional terms do not indicate and imply that the device or element being referred to must have a particular orientation or be constructed and operated in a particular orientation, and therefore, should not be considered as limiting the scope of the present application; the terms "inner and outer" refer to the inner and outer relative to the profile of the respective component itself.

Both ends of the ground line 123 of the branching device 120 are connected to the common (ground) C1 of the sound source input connector 140 and the common (ground) C2 of the terminal input/output connector 150, respectively.

In some embodiments of the present invention, the wire separating device 120 further includes a resistor 124 for microphone detection. The two ends of the resistor 124 are connected to the microphone branch 122 and the ground 123, respectively. Preferably, the resistor 124 may be a 2.2Kohm resistor, but the embodiment is not limited thereto.

In one example shown in fig. 3, a first test voice provided by the audio source 110 enters the first terminal 10 via the left channel a1 of the audio source input connector 140, the microphone splitter 122 of the splitter 120, and the microphone D2 of the terminal input/output connector 150.

It should be understood that the first terminal 10 and the second terminal 20 may be mobile devices having voice communication functions, including but not limited to mobile phones, tablet computers, and walkie talkies. The first terminal 10 and the second terminal 20 may be provided with terminal input and output interfaces corresponding to the terminal input and output connector 150 according to the needs of those skilled in the art.

In some embodiments of the present invention, the first terminal 10 and the second terminal 20 further have a voice input component and a voice playing component. Illustratively, the voice input component may be a microphone; the voice playing component may be a Speaker and/or a Receiver. In some examples, the voice input component and the voice playback component described above may be built into the first terminal 10 and the second terminal 20. In other examples, the first terminal 10 and the second terminal 20 may be further connected to an external voice input component and/or a voice playing component to implement a voice input function and/or a voice playing function.

The operation of the voice quality testing system 100 will be described with reference to fig. 1.

Referring to the direction shown by the solid line in fig. 1, the first test voice provided from the voice source 110 enters the first terminal 10 through the voice source input connector 140, the microphone splitter 122 and the terminal input-output connector 150, and is transmitted from the first terminal 10 to the second terminal 20.

In some examples of the present invention, the second terminal 20 can be played by a voice playing component (e.g. a receiver or a speaker) built in the second terminal 20 after receiving the first test voice sent from the first terminal 10, so as to be heard by the testee.

Referring to the direction shown by the dotted line in fig. 1, the second test voice received by the first terminal 10 from the second terminal 20 can be transmitted to the earphone 130 through the terminal input/output connector 150 and the earphone line 121, so that the testee can hear the second test voice.

In some examples of the invention, the second test voice may be emitted by the tester. Illustratively, a tester may speak near the second terminal 20, and the tester's voice may be entered into the second terminal 20 through a voice input component (e.g., a microphone) built into the second terminal 20.

It should be understood that the first test voice may be transmitted from the first terminal 10 to the second terminal 20 over an Air Interface. Similarly, the second test voice may be sent from the second terminal 20 to the first terminal 10 over the air interface. The "air interface" is a radio transmission specification between a base station and a mobile device, and defines the frequency of use, bandwidth, access timing, coding method, handover, and the like of each radio channel.

In one example shown in fig. 1, the earphones 130 include a left ear earphone 130a and a right ear earphone 130b, and the left ear earphone 130a is wrapped with a sound insulating material. After receiving the first test voice from the first terminal 10, the second terminal 20 plays the test voice through a receiver built in the second terminal 20, so that the left ear of the test subject can hear the test voice. After receiving the second test voice from the second terminal 20, the first terminal 10 may transmit the second test voice to the right ear phone 130b through the terminal input/output connector 150 and the phone splitter 121, so that the second test voice can be heard by the right ear of the testee.

It is understood that one or more of the above-described testers may be present. For example, the tester wearing the headset may be the same or different from the tester making the second test voice. In the preferred embodiment of the present invention, the earphone 130 is suitable for being worn by the tester and the second testing voice comes from the tester wearing the earphone 130.

The utility model discloses an above embodiment provides a voice quality testing system, and this voice quality testing system can effectively reduce the test degree of difficulty and the test cost of voice quality.
