Description

  The present invention relates to a sound receiver and a sound generation function test apparatus, and is intended to test the sound characteristics of a sound receiver such as a headphone connected to an earphone jack of an electronic device as a test target such as a portable terminal, and the electronic device. The present invention relates to a sound generation function test apparatus used in the above.

A small electronic device such as a mobile phone, a simple mobile phone (PHS), or a personal digital assistant (PDA) is provided with an earphone jack for listening to sound and music using the earphone.
Conventionally, as part of a test related to the sound generation function of an electronic device such as a portable terminal, a test for determining whether or not a desired signal is output from an earphone jack to which the earphone is connected is performed. For example, a headphone for testing is connected to this earphone jack, and the tester can listen to the sound or music actually emitted from the vicinity of the ear, or connect a speaker to the earphone jack without wearing the headphone etc. The sensory test is performed by judging the quality by listening to the generated sound.

However, in general, in the production line of small electronic devices as described above, a plurality of lines are often densely packed, and when performing a sensory test using a speaker, the tester must perform the same test on adjacent lines. It is indistinguishable from the sound generated from the speakers used in the process, and even if no sound is emitted from the target speaker, there is a possibility that the electronic device under test may be mistakenly judged as a good product there were.
In addition, when the tester conducts a sensory test with headphones, the influence of surrounding sound sources can be eliminated, but there are concerns about health damage such as hearing loss due to wearing headphones for a long time. There is a problem that the tester is burdened. Furthermore, for example, there was a problem that sirens and emergency broadcast sounds could not be heard in an emergency.

For this reason, a headphone has been proposed in which an openable / closable lid is attached to the earphone so that it can be opened or closed as necessary (see, for example, Patent Document 1). By testing using such headphones, external sounds are cut off during the test to concentrate on the sound emitted from the earphones to prevent judgment errors and other sounds can be easily heard outside the test. It becomes possible to do so.
In addition, a technique for amplifying an electric signal supplied from an earphone jack of an electronic device and emitting a generated sound from a speaker has also been proposed (see, for example, Patent Document 2).

Since the motor drive signal is supplied to control the lids 15 and 31 so as to open, for example, even when a complicated test is performed, the test can be performed accurately and reliably.

In addition, the lid is automatically opened except when necessary (that is, during the test), you can easily hear the sound coming from the outside, can prevent health damage such as hearing loss, The burden on the examiner can be reduced. Furthermore, for example, it is possible to avoid a problem that sirens and emergency broadcast sounds are difficult to hear in an emergency.
Further, the controller 4 supplies a motor drive signal to the test headphones 3 before starting the test, and closes the lid portions 15 and 31 by the rotation of the motors 18 and 32. After the test is completed, the test headphones 3 Since the motor drive signal is supplied to control the lids 15 and 31 to open, the burden on the tester can be reduced even when a complicated test is performed, for example.

The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and there are design changes and the like without departing from the gist of the present invention. Are also included in the present invention.
For example, in the above-described embodiments, the case where a motor is used as the driving unit has been described. However, in addition to this, a magnet or a spring may be used in combination, or air may be used.
Moreover, although the case where the lid is rotated around the rotation axis to open and close has been described, it may be opened and closed by a sliding operation. In this case, a single motor may be arranged at the center of the headband, for example, and the lids of both earphone units may be displaced simultaneously.

Alternatively, the operating member may be eliminated and the lid portion may be directly attached to the motor shaft and rotated. Here, you may comprise so that a cover part may be rotated so that the surface normal of a cover part may become mutually parallel with a rotating shaft.
Further, when the connection plug of the headphones is fitted to the earphone jack, a connection detection signal may be transmitted from the mobile phone to the controller.
Moreover, you may apply to the headset with which the microphone was mounted | worn. Further, the present invention may be applied to a single earphone as well as the headphone.
