Description
Technical Field
The utility model relates to the technical field of electronic equipment, in particular to an earphone device.
Background
In-ear headphones and headsets (commonly referred to collectively as audible headphones or earphone devices), the collection of more advanced functions controlled by a range of complex User Interfaces (UIs) is becoming increasingly common. Generally, in a rich-function headphone apparatus, a combination of buttons and/or a touch interface is used in the UI. As the volume of headphone devices decreases, physically moving buttons are no longer common and touch interfaces (capacitive or other types) are becoming the primary control interface. However, feedback is lacking in the interaction on the touch interface, such as feedback whether a touch or gesture is registered. Therefore, it is generally required to add a function of tactile feedback in the headphone device.
The prior art is to vibrate or rotate an actuator or motor by an amount through an input signal waveform, which produces a vibratory sensation to create haptic feedback. However, the actuator or motor may take up space in the audible wearable device. For example, one minimum volume haptic feedback motor currently available has an outer diameter of 7mm and a height of 2 mm. The components used to generate the vibrations for haptic feedback are still large compared to the typical components used in audible wearable devices. Thus, while haptic feedback is a desirable function in a touch-controlled enabled device, the actuators or motors required to generate the vibrations of the haptic feedback can consume space within the space-constrained product.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present invention.
According to an embodiment of the present invention, there is provided an earphone device. Fig. 1 is a block diagram of an earphone device 100 according to an embodiment of the present invention. The earphone device 100 may comprise an in-ear earphone, a headset, or any other type of earphone device. As shown in fig. 1, the headphone apparatus 100 includes a speaker unit 1022, and music or voice content of the headphone apparatus 100 can be played through the speaker unit 1022. The assembly of the speaker units may include magnets, a voice coil, and a diaphragm, the diaphragm may be located between the magnets, and the diaphragm is connected to the voice coil. A triggering instruction requiring tactile feedback may be sent to the headphone apparatus 100. The trigger instruction may be, for example, an instruction generated by a touch (e.g., clicking on a touch interface) or gesture (e.g., sliding a finger on the touch interface) of a user, even an instruction generated in response to played music or voice content, and even an instruction from another device connected to the ear speaker device 100. Furthermore, the trigger instruction may be any instruction that requires tactile feedback in the form of vibration.
The earphone device 100 may further include a pulse sequence obtaining unit 1021, and after the earphone device 100 receives the trigger instruction, the pulse sequence obtaining unit 1021 is configured to obtain the ultra-low frequency pulse sequence. The speaker unit 1022 may be connected to the pulse sequence acquiring unit 1021 and receive the ultra low frequency pulse sequence through the pulse sequence acquiring unit 1021. In response to the received trigger instruction, the speaker unit 1022 of the headphone apparatus 100 uses the ultra-low frequency pulse sequence to make the speaker unit 1022 respond to the ultra-low frequency pulse sequence, and generates the tactile feedback of the trigger instruction. The speaker unit 1022 may play the sound using the ultra-low frequency pulse train, and the low frequency sound generated by the ultra-low frequency pulse train may be selectively heard or not heard by human ears according to the setting of the frequency by the designer, for example, if the setting of the frequency by the designer is lower than the lower threshold of the hearing ability of human ears for the frequency, an output that is not heard by human ears may be generated. Otherwise, an output audible to the human ear may be produced. Whereas low frequency sound generated by a sequence of ultra low frequency pulses can produce an auditory effect similar to vibration compared to distinguishable tones, the output produced by such frequency settings can be used as a vibration for haptic feedback.
Compared with the existing earphone device which generates vibration by an actuator or a motor as the tactile feedback, the earphone device provided by the utility model can omit the use of the actuator or the motor, thereby saving more space and reducing cost. In addition, since the actuator does not have a diaphragm or an acoustic element of the speaker unit, even though the actuator can generate a sound audible to human ears when operating at a specific frequency, the sound cannot actually play the music or voice content of the earphone device 100, because the sound is a monotonous vibration noise, similar to a buzzer, the earphone device provided by the present invention can achieve a special effect that only the speaker unit can achieve, i.e., can simultaneously perform two functions of playing music and providing tactile feedback.
In one example, the outer diameter of one minimum volume haptic feedback motor currently available is 7mm and the height is 2 mm. Typical components used in headphone sets, such as speaker units, may be 5mm by 3mm in size. It can be seen that the haptic feedback motors used in the prior art are large in size compared to the typical components used in headphone settings. The earphone device provided by the utility model can omit a separate component (such as a motor or an actuator) for generating vibration, thereby effectively saving the internal space of the earphone device.
Fig. 2 shows a block diagram of an earphone device according to another embodiment of the present invention. In addition to the speaker unit 1022, the earphone device 100 may further include a user interface 104, and a trigger instruction requiring tactile feedback may be sent to the earphone device 100 through the user interface 104. The user interface 104 may be, for example, a capacitive or other type of touch interface. In one example, a user's touch or gesture may be received through the touch interface, and in response to a trigger instruction from the user's touch or gesture, the speaker unit 1022 plays a sound similar to a vibration auditory effect using an ultra-low frequency pulse sequence as tactile feedback that the touch or gesture is registered or unregistered. In another example, the haptic feedback may be generated according to music or voice content played by the earphone device, for example, when the earphone device plays a sound effect like explosion or simulated vibration, a corresponding trigger instruction may be generated according to the played content to trigger the haptic feedback.
As shown in fig. 2, the earphone device 100 may further include a memory 106, and the ultra-low frequency pulse sequence may be pre-stored in the memory 106, so that the speaker unit 1022 may retrieve the ultra-low frequency pulse sequence from the memory 106 to play a sound as a tactile feedback. In some embodiments, the earphone device 100 may further include a pulse sequence generating unit 108 for generating an ultra-low frequency pulse sequence. In some embodiments, the pulse sequence generating unit 108 may be a processor, and the pulse sequence generating unit 108 may be configured to generate the ultra low frequency pulse sequence in real time after the earphone device 100 receives the trigger instruction. The processor may be a Digital Signal Processor (DSP) or other type of processing device. The earphone device 100 shown in fig. 2 includes a memory 106 and a pulse sequence generation unit 108, but in other embodiments, the earphone device may include one of the memory 106 and the pulse sequence generation unit 108.
Fig. 3 is a block diagram of a pulse sequence generating unit according to an embodiment of the present invention. As shown in fig. 3, the pulse sequence generating unit 108 may include a pulse modulation module 1082, and the pulse modulation module 1082 is configured to generate the ultra-low frequency pulse sequence by pulse amplitude modulating the carrier waveform. In other embodiments, the pulse sequence generating unit 108 may also generate the ultra-low frequency pulse sequence by using other applicable methods. In general, the ultra low frequency range refers to a range of frequencies below 300 Hz. In some embodiments, the pulse sequence generation unit 108 comprises a frequency selection module 1084, the frequency selection module 1084 being configured to select the frequency of the carrier of the ultra low frequency pulse sequence to be a lower threshold (e.g., 20Hz) of the human ear's auditory frequency range, such that low frequency sound played through the ultra low frequency pulse sequence is audible to the human ear and the resulting auditory sensation may resemble vibrations. In addition, the pulse sequence generating unit 108 includes a mute configuration module 1086, and the mute configuration module 1086 is configured to form the ultra-low frequency pulse sequence to have a mute time period between adjacent pulses.
Fig. 4 is a waveform diagram illustrating an ultra low frequency pulse train according to an embodiment of the present invention, and fig. 4 is a waveform diagram illustrating an ultra low frequency pulse train truncated by a window function. The lower threshold of the frequency range of audible sounds audible by human ear is 20Hz, and as shown in fig. 4, the frequency of the carrier wave of the sequence of ultra low frequency pulses is selected to be 20Hz with a silent period of 0.02s duration between adjacent pulses. It will be appreciated that other choices of the relevant parameters of the ultra low frequency pulse sequence are possible.
The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions, improvements, etc. within the spirit and principle of the present invention should be included in the protection scope of the present invention.
