Definitions
- This disclosure relates to a headphone device, especially to a headband-style headphone device whose form factor in compact storage is relatively smaller.
- the earphone devices in the marketplace may be divided into three categories according to the appearances: headband-style headphones, in-ear headphones, and ear hook headphones.
- Headband-style headphones are usually designed to fully encompass the ears with earpads to block outside noises and seal music in, and thus offer a relatively entertaining sound quality. They are also rigid and shatterproof yet with the drawbacks of large form factor and very limited collapsibility resulting in inconveniences of carrying them around. Hence, such headphones are the least portable and therefore much more suitable for home use.
- In-ear headphones are configured to be snugly inserted into the ear canals with the part of the audio output transducers. They are portable, lightweight, and fit for many portable electronic devices like Walkman and cell-phones. As a plus, they have small form factor. However, the only drawback thereof is that listeners cannot be isolated satisfactorily from outside noise or sound.
- Ear hook headphones attaching around the ears have size (form factor) and sound quality between the headband-style headphones and the in-ear headphones. Because the audio output transducers thereof are hung around the ears, better acoustic isolation and sound quality than the in-ear type can be provided. However, in terms of sound quality and audio performance, the headband-style headphone is the best choice.
- this disclosure solves the above problems by providing a headband-style headphone device whose form factor is relatively smaller when in compact storage.
- a headphone device in one embodiment, includes a first audio output module, a second audio output module, and a head module.
- the first audio output module outputs an audio signal of a left channel.
- the second audio output module outputs an audio signal of a right channel.
- the head module connected between the first audio output module and the second audio output module that are located at both ends of the head module respectively.
- the head module stays bent when in use to allow a user listen to audio signals comfortably, and stays straight when in compact storage and can be accommodated into the first and the second audio output modules as far as possible, thus the form factor of the headphone device is reduced.
- the head module can further include a flexible metal strip made of robust steel so that the flexible metal strip stays bent or straight normally when the headphone device is in use or in compact storage. And the flexible metal strip can be forced to deform and stays bent to fit the user's head.
- a headphone device in another embodiment, includes a first audio output module, a second audio output module, a head module, a wireless module, a volume control module and a cord.
- the wireless receiving module is electrically connected to the first audio output module for receiving and transforming a wireless signal from an electronic device into an audio signal which is to be transmitted to the second audio output module through the cord.
- This disclosure is advantageous basically because when the headphone device is in compact storage, the head module can be straightened and part of it can be accommodated into the first and second audio output modules as far as possible. Thus the form factor of the headphone device can be reduced greatly and becomes highly portable.

Abstract
Description
- This disclosure relates to a headphone device, especially to a headband-style headphone device whose form factor in compact storage is relatively smaller.
- The earphone devices in the marketplace may be divided into three categories according to the appearances: headband-style headphones, in-ear headphones, and ear hook headphones.
- Headband-style headphones are usually designed to fully encompass the ears with earpads to block outside noises and seal music in, and thus offer a relatively fabulous sound quality. They are also rigid and shatterproof yet with the drawbacks of large form factor and very limited collapsibility resulting in inconveniences of carrying them around. Hence, such headphones are the least portable and therefore much more suitable for home use.
- In-ear headphones are configured to be snugly inserted into the ear canals with the part of the audio output transducers. They are portable, lightweight, and fit for many portable electronic devices like Walkman and cell-phones. As a plus, they have small form factor. However, the only drawback thereof is that listeners cannot be isolated satisfactorily from outside noise or sound.
- Ear hook headphones attaching around the ears have size (form factor) and sound quality between the headband-style headphones and the in-ear headphones. Because the audio output transducers thereof are hung around the ears, better acoustic isolation and sound quality than the in-ear type can be provided. However, in terms of sound quality and audio performance, the headband-style headphone is the best choice.
- So there is a need to develop a headband-style headphone free of the above drawbacks without sacrificing the sound quality.
- In view of this, this disclosure solves the above problems by providing a headband-style headphone device whose form factor is relatively smaller when in compact storage.
- In one embodiment, a headphone device includes a first audio output module, a second audio output module, and a head module. The first audio output module outputs an audio signal of a left channel. The second audio output module outputs an audio signal of a right channel. The head module connected between the first audio output module and the second audio output module that are located at both ends of the head module respectively. The head module stays bent when in use to allow a user listen to audio signals comfortably, and stays straight when in compact storage and can be accommodated into the first and the second audio output modules as far as possible, thus the form factor of the headphone device is reduced.
- In this embodiment, the head module can further include a flexible metal strip made of robust steel so that the flexible metal strip stays bent or straight normally when the headphone device is in use or in compact storage. And the flexible metal strip can be forced to deform and stays bent to fit the user's head.
- In another embodiment, a headphone device includes a first audio output module, a second audio output module, a head module, a wireless module, a volume control module and a cord. The wireless receiving module is electrically connected to the first audio output module for receiving and transforming a wireless signal from an electronic device into an audio signal which is to be transmitted to the second audio output module through the cord.
- This disclosure is advantageous basically because when the headphone device is in compact storage, the head module can be straightened and part of it can be accommodated into the first and second audio output modules as far as possible. Thus the form factor of the headphone device can be reduced greatly and becomes highly portable.

head module 100 includes aflexible metal strip 101 which can be made of but not limited to robust stainless steel. One of ordinary skill in the art can select any deformable metal as material of theflexible metal strip 101 and determine the form factor thereof by manipulating thickness and length for example according to practical requirements. - The

One of thefirst projections 103 and one of thesecond projections 104 respectively correspond and are buckled to a first concave 111 disposed in the firstaudio output module 110 and a second concave 121 disposed in the secondaudio output module 120. Thus the relative position of thehead module 100, the firstaudio output module 110 and the secondaudio output module 120 can be fixed either in use (service mode) or in compact storage (storage mode). - When the
headphone device 10 is put to use, theflexible metal strip 101 is forced to deform and stay bent to fit the user's head, so that the user may feel comfortable with theheadphone device 10. - Besides, the

Fig. 3A to Fig. 3C are structure diagrams of an audio output module of the headphone device of the first embodiment particularly showing how thesecond projections 104 correspond and are buckled to the second concave 121. It is appreciated that since the connection between firstaudio output module 110 and thehead module 100 is the same as that between the secondaudio output module 120 and thehead module 100, only the secondaudio output module 120 is described for illustration in the following paragraphs. - In

headphone device 10 is turned into a compact storage form is depicted by referring toFig. 3A . As a first step, force is applied to deform theflexible metal strip 101 such that thehead module 100 stays straight. Then, the relative position of the firstaudio output module 110, the secondaudio output module 120 and theflexible metal strip 101 is adjusted by buckling theprojection 1041 which is closest to thehead cushion module 102 to the second concave 121. Thus theflexible metal strip 101 can be accommodated into the secondaudio output modules 120 as far as possible, and the form factor of theheadphone device 10 is reduced. - How the
headphone device 10 is turned into a service mode is depicted by referring toFig. 3B . As a first step, force is applied to theflexible metal strip 101 such that thehead module 100 stays bent. Then, one of theprojection 104i is selected to be buckled to the second concave 121 according to the head size and the customary practice for example, where i is an integer ranging from 1 to n, so that thehead module 100 is exposed from the first and secondaudio output modules - Referring to
Fig. 3C , aprotective projection 104s is provided next to theprojection 104n. When theprojection 104n closest to the end of theflexible metal strip 101 is buckled to the second concave 121 and the user want to further lengthen thehead module 100 by exposing more part of thehead module 100 from the first and secondaudio output modules protective projection 104s will serve to impede from increase of the length of thehead module 100 that is exposed from the first and secondaudio output modules flexible metal strip 101 from coming off the secondaudio output module 120 and breaking down theheadphone device 10. -

headphone device 20 receives from an electronic device electronic signals through thewireless module 270. The electronic signals are then transformed into wireless radiofrequency ones to be transmitted to the first and secondaudio output modules audio output modules - Alternatively, the signal processing module is incorporated only in the first
audio output module 210, and the sound waves are transmitted therefrom to the secondaudio output module 220 through the cord which is connected to the first and secondaudio output modules - It is noted that the
audio input module 250 and thevolume control module 260 in this embodiment function in the same way as theaudio input module 150 and thevolume control module 160 in the first embodiment respectively and will not be described further here.

headphone device 20 is in a service mode, the connectingmodule 240 can be extended from the secondaudio output module 220 in a flexible way to make theaudio input module 250 approximate to the listener's mouth as a voice receiver. Furthermore, thevolume control module 260 is disposed under theaudio input module 250 to allow an easy control of the volume of the first and secondaudio output modules -
Fig. 5 shows theheadphone device 20 of the second embodiment in compact storage. The connectingmodule 240 can be accommodated into the secondaudio output module 220 in a straight form. Theprojections head cushion module 202 can be buckled to the first concave 211 and the second concave 221 respectively. Thus theflexible metal strip 201 can be accommodated into the first and secondaudio output modules headphone device 20 is reduced. - It is noted that the embodiments are used as an exemplary interpretation of a headphone device without any intention to limit the scope of this disclosure. Those skilled in the art may modify the appearance and the function of the headphone device according to the user's requirements.
- This disclosure is advantageous because, on one hand, the flexible metal strip can be forced to stay straight and the head module becomes compact on the whole; on the other hand, part of the head module can be accommodated into the first and second audio output modules as far as possible and the form factor of the headphone device is thus reduced.
