A cone is a three-dimensional geometric shape that is usually made of paper, plastic, or metal. It has a wide end and a pointed end, with the wide end attached to the suspension.

In human anatomy, the eardrum, or tympanic membrane, is a thin, cone-shaped membrane that separates the external ear from the middle ear in humans and other tetrapods. Its function is to transmit sound from the air to the ossicles inside the middle ear, and then to the oval window in the fluid-filled cochlea.

The correct answer is Suspension, Surround. The explanation is that the rim of flexible material, known as the suspension, allows the cone to move. It is attached to the driver's metal frame, called the basket. The surround is also a part of the speaker that helps to support and control the movement of the cone. Together, the suspension and surround play a crucial role in allowing the cone to move and produce sound effectively.

It is a japanese principle that simply means " a place for everything and everything in its place."

This answer is correct because electrostatic speakers use a large, thin, conductive diaphragm panel to vibrate the air and produce sound. Electrostatic speakers work by applying an electrical charge to the diaphragm, which is sandwiched between two perforated metal plates. When an audio signal is applied to the diaphragm, it moves back and forth, causing the air around it to vibrate and produce sound waves. This design allows for accurate and detailed sound reproduction, making electrostatic speakers popular among audiophiles.

The spider is a part of a speaker that holds the coil in position but allows it to move freely back and forth. It acts as a suspension system, providing support and stability to the coil while still allowing it to vibrate and produce sound. The spider is typically made of a flexible material such as fabric or rubber, and its design and construction play a crucial role in the overall performance and sound quality of the speaker.

The correct answer is "Voice coil, Coil". The voice coil is an essential component of a speaker that converts electrical signals into mechanical vibrations, producing sound. It is a coil of wire that is placed within a magnetic field created by a permanent magnet. When an electrical current passes through the coil, it generates a magnetic field that interacts with the permanent magnet, causing the coil to move back and forth rapidly. This movement creates vibrations in the speaker cone, which in turn produces sound waves. Therefore, the voice coil, which is essentially a coil of wire, is an integral part of the electromagnet in a speaker.

It is a class of electronic filter used in audio applications. Most individual loudspeaker drivers are incapable of covering the entire audio spectrum from low frequencies to high frequencies with acceptable relative volume and absence of distortion so most hi-fi speaker systems use a combination of multiple loudspeaker drivers, each catering to a different frequency band.

n electronics and communications, the decibel (abbreviated as dB, and also as db and DB) is a logarithmic expression of the ratio between two signal power, voltage, or current levels. In acoustics, the decibel is used as an absolute indicator of sound power per unit area. A decibel is one-tenth of a Bel, a seldom-used unit named for Alexander Graham Bell, inventor of the telephone.

A passive crossover is a type of crossover that does not require an external power source to function. It is activated solely by the audio signal passing through it. This means that it operates passively, without the need for additional power or amplification. Passive crossovers are commonly used in audio systems to separate the audio signal into different frequency ranges and direct them to the appropriate speakers or drivers.

Woofers, woofer, and bass are the correct answer because they are all related to producing low frequency sounds. Woofers are specialized speakers designed to reproduce low-frequency sounds, while a woofer is a type of speaker driver that is responsible for producing bass frequencies. Bass refers to the low-pitched tones in music or sound. Therefore, all three terms are associated with the production of low frequency sounds.

A loudspeaker enclosure or loudspeaker cabinet is an enclosure in which speaker drivers and associated electronic hardware, such as crossover circuits and amplifiers, are mounted. Enclosures may range in design from simple, rectangular particle-board boxes to very complex cabinets that incorporate composite materials, internal baffles, horns, ports and acoustic insulation.

Sound waves with greater amplitudes move our ear drums more, and we register this sensation as a higher volume.

A microphone, colloquially mic or mike (/ˈmaɪk/),[1] is an acoustic-to-electric transducer or sensor that converts sound into an electrical signal. Electromagnetic transducers facilitate the conversion of acoustic signals into electrical signals.[2] Microphones are used in many applications such as telephones, hearing aids, public address systems for concert halls and public events, motion picture production, live and recorded audio engineering, two-way radios, megaphones, radio and television broadcasting, and in computers for recording voice, speech recognition, VoIP, and for non-acoustic purposes such as ultrasonic checking or knock sensors.

The term "midrange" or "mid-range" refers to a speaker that is designed to produce a range of frequencies in the middle of the sound spectrum. This means that it is capable of reproducing sounds that fall within a specific frequency range, typically between the lower bass frequencies and the higher treble frequencies. Midrange speakers are important in audio systems as they help to provide clarity and detail to the sound, ensuring that all frequencies are adequately represented.

The correct answer is "Sort, Seiri." This answer refers to a Japanese principle known as "Seiri," which means to remove unnecessary things or unwanted materials. This principle emphasizes the importance of organizing and decluttering one's surroundings by getting rid of items that are no longer needed. By sorting and removing unnecessary things, individuals can create a more efficient and productive environment.

Passive Radiator Enclosure has a passive driver just like the main, active drivers except it doesn't have an electromagnet voice coil, and it isn't connected to the amplifier. It is moved only by the sound waves coming from the active drivers. This type of enclosure is more efficient than sealed designs and more precise than bass reflex models.

A speaker is a device that converts analog audio signals into air vibrations, which are then perceived as sound. It takes electrical signals and transforms them into physical vibrations, causing the surrounding air to vibrate and produce audible sound waves. Speakers are commonly used in audio systems, such as in televisions, radios, and music players, to reproduce sound for the listener. They are essential for converting electronic signals into sound that can be heard by humans.

The statement is incorrect because a higher wave frequency actually means that the air pressure fluctuates faster, not slower. In a speaker, the wave frequency determines the pitch of the sound produced. Higher frequencies result in higher-pitched sounds, which are generated by faster air pressure fluctuations. Therefore, the correct answer is "No Deal."
